Subject: [PATCH 01/69] dtbindings: qcom_adm: Fix channel specifiers
Original patch from Andy Gross.
This patch removes the crci information from the dma
channel property. At least one client device requires
using more than one CRCI value for a channel. This does
not match the current binding and the crci information
needs to be removed.
Instead, the client device will provide this information
via other means.

Subject: [PATCH 02/69] dmaengine: Add ADM driver
Original patch by Andy Gross.
Add the DMA engine driver for the QCOM Application Data Mover (ADM) DMA
controller found in the MSM8x60 and IPQ/APQ8064 platforms.
The ADM supports both memory to memory transactions and memory
to/from peripheral device transactions. The controller also provides flow
control capabilities for transactions to/from peripheral devices.
The initial release of this driver supports slave transfers to/from peripherals
and also incorporates CRCI (client rate control interface) flow control.

Subject: [PATCH 04/69] spi: qup: Fix transaction done signaling
Wait to signal done until we get all of the interrupts we are expecting
to get for a transaction. If we don't wait for the input done flag, we
can be inbetween transactions when the done flag comes in and this can
mess up the next transaction.

Subject: [PATCH 05/69] spi: qup: Fix DMA mode to work correctly
This patch fixes a few issues with the DMA mode. The QUP needs to be
placed in the run mode before the DMA transactions are executed. The
conditions for being able to DMA vary between revisions of the QUP.
This is due to v1.1.1 using ADM DMA and later revisions using BAM.

Subject: [PATCH 07/69] spi: qup: properly detect extra interrupts
It's possible for a SPI transaction to complete and get another
interrupt and have it processed on the same spi_transfer before the
transfer_one can set it to NULL.
This masks unexpected interrupts, so let's set the spi_transfer to
NULL in the interrupt once the transaction is done. So we can
properly detect these bad interrupts and print warning messages.

is done for reads
For reads, we will get another interrupt so we need to handle things
then. For writes, we can finish up now.

Subject: [PATCH 09/69] spi: qup: refactor spi_qup_io_config in two functions
This is preparation for handling transactions larger than 64K-1 bytes in
block mode which is currently unsupported quietly fails.
We need to break these into two functions 1) prep is called once per
spi_message and 2) io_config is calle once per spi-qup bus transaction
This is just refactoring, there should be no functional change

Subject: [PATCH 10/69] spi: qup: call io_config in mode specific function
DMA transactions should only only need to call io_config only once, but
block mode might call it several times to setup several transactions so
it can handle reads/writes larger than the max size per transaction, so
we move the call to the do_ functions.
This is just refactoring, there should be no functional change

Subject: [PATCH 11/69] spi: qup: allow block mode to generate multiple
transactions
This let's you write more to the SPI bus than 64K-1 which is important
if the block size of a SPI device is >= 64K or some other device wants
to something larger.
This has the benefit of completly removing spi_message from the spi-qup
transactions

Subject: [PATCH 14/69] spi: qup: Fix sg nents calculation
lib/scatterlist.c:sg_nents_for_len() returns the number of SG
entries that total up to greater than or equal to the given
length. However, the spi-qup driver assumed that the returned
nents is for a total less than or equal to the given length. The
spi-qup driver requests nents for SPI_MAX_XFER, however the API
returns nents for SPI_MAX_XFER+delta (actually SZ_64K).
Based on this, spi_qup_do_dma() calculates n_words and programs
that into QUP_MX_{IN|OUT}PUT_CNT register. The calculated
n_words value is more than the maximum value that can fit in the
the 16-bit COUNT field of the QUP_MX_{IN|OUT}PUT_CNT register.
And, the field gets programmed to zero. Since the COUNT field is
zero, the i/o doesn't start eventually resulting in the i/o
timing out.

Subject: [PATCH 27/69] clk: qcom: Add support for SMD-RPM Clocks
This adds initial support for clocks controlled by the Resource
Power Manager (RPM) processor on some Qualcomm SoCs, which use
the qcom_smd_rpm driver to communicate with RPM.
Such platforms are msm8916, apq8084 and msm8974.
The RPM is a dedicated hardware engine for managing the shared
SoC resources in order to keep the lowest power profile. It
communicates with other hardware subsystems via shared memory
and accepts clock requests, aggregates the requests and turns
the clocks on/off or scales them on demand.
This driver is based on the codeaurora.org driver:

Subject: [PATCH 28/69] clk: qcom: Add support for RPM Clocks
This adds initial support for clocks controlled by the Resource
Power Manager (RPM) processor on some Qualcomm SoCs, which use
the qcom_rpm driver to communicate with RPM.
Such platforms are apq8064 and msm8960.

On QCOM platforms using MTD devices storage (such as IPQ806x), SMEM is
used to store partition layout. This new parser can now be used to read
SMEM and use it to register an MTD layout according to its content.

Subject: [PATCH 33/69] ARM: qcom: automatically select PCI_DOMAINS if PCI is
enabled
If multiple PCIe devices are present in the system, the kernel will
panic at boot time when trying to scan the PCI buses. This happens on
IPQ806x based platforms, which has 3 PCIe ports.
Enabling this option allows the kernel to assign the pci-domains
according to the device-tree content. This allows multiple PCIe
controllers to coexist in the system.

Krait CPUs have a handful of L2 cache controller registers that
live behind a cp15 based indirection register. First you program
the indirection register (l2cpselr) to point the L2 'window'
register (l2cpdr) at what you want to read/write. Then you
read/write the 'window' register to do what you want. The
l2cpselr register is not banked per-cpu so we must lock around
accesses to it to prevent other CPUs from re-pointing l2cpdr
underneath us.

We want to reuse the logic in clk-mux.c for other clock drivers
that don't use readl as register accessors. Fortunately, there
really isn't much to the mux code besides the table indirection
and quirk flags if you assume any bit shifting and masking has
been done already. Pull that logic out into reusable functions
that operate on an optional table and some flags so that other
drivers can use the same logic.

From: Stephen Boyd <sboyd@codeaurora.org>
On some devices (MSM8974 for example), the HFPLLs are
instantiated within the Krait processor subsystem as separate
register regions. Add a driver for these PLLs so that we can
provide HFPLL clocks for use by the system.

From: Stephen Boyd <sboyd@codeaurora.org>
The Krait clocks are made up of a series of muxes and a divider
that choose between a fixed rate clock and dedicated HFPLLs for
each CPU. Instead of using mmio accesses to remux parents, the
Krait implementation exposes the remux control via cp15
registers. Support these clocks.

The ACC and GCC regions present in KPSSv1 contain registers to
control clocks and power to each Krait CPU and L2. For CPUfreq
purposes probe these devices and expose a mux clock that chooses
between PXO and PLL8.

The Krait CPU clocks are made up of a primary mux and secondary
mux for each CPU and the L2, controlled via cp15 accessors. For
Kraits within KPSSv1 each secondary mux accepts a different aux
source, but on KPSSv2 each secondary mux accepts the same aux
source.

When the Hfplls are reprogrammed during the rate change,
the primary muxes which are sourced from the same hfpll
for higher frequencies, needs to be switched to the 'safe
secondary mux' as the parent for that small window. This
is done by registering a clk notifier for the muxes and
switching to the safe parent in the PRE_RATE_CHANGE notifier
and back to the original parent in the POST_RATE_CHANGE notifier.

The Platform data was removed earlier by,
'commit eb96924acddc ("cpufreq: dt: Kill platform-data")'
since there were no users at that time.
Now this is required when the each of the cpu clocks
can be scaled independently, which is the case
for krait cores. So reintroduce it.

Subject: [PATCH 47/69] mtd: nand: Create a BBT flag to access bad block
markers in raw mode
Some controllers can access the factory bad block marker from OOB only
when they read it in raw mode. When ECC is enabled, these controllers
discard reading/writing bad block markers, preventing access to them
altogether.
The bbt driver assumes MTD_OPS_PLACE_OOB when scanning for bad blocks.
This results in the nand driver's ecc->read_oob() op to be called, which
works with ECC enabled.
Create a new BBT option flag that tells nand_bbt to force the mode to
MTD_OPS_RAW. This would result in the correct op being called for the
underlying nand controller driver.

Subject: [PATCH 49/69] PM / OPP: Support adjusting OPP voltages at runtime
On some SoCs the Adaptive Voltage Scaling (AVS) technique is
employed to optimize the operating voltage of a device. At a
given frequency, the hardware monitors dynamic factors and either
makes a suggestion for how much to adjust a voltage for the
current frequency, or it automatically adjusts the voltage
without software intervention. Add an API to the OPP library for
the former case, so that AVS type devices can update the voltages
for an OPP when the hardware determines the voltage should
change. The assumption is that drivers like CPUfreq or devfreq
will register for the OPP notifiers and adjust the voltage
according to suggestions that AVS makes.

Subject: [PATCH 50/69] OPP: Allow notifiers to call dev_pm_opp_get_{voltage,
freq} RCU-free
We pass the dev_pm_opp structure to OPP notifiers but the users
of the notifier need to surround calls to dev_pm_opp_get_*() with
RCU read locks to avoid lockdep warnings. The notifier is already
called with the dev_opp's srcu lock held, so it should be safe to
assume the devm_pm_opp structure is already protected inside the
notifier. Update the lockdep check for this.

When the voltage is adjusted, the voltage tolerance is not updated.
This can lead to situations where the voltage min value is greater

Subject: [PATCH 54/69] cpufreq-dt: Handle OPP voltage adjust events
On some SoCs the Adaptive Voltage Scaling (AVS) technique is
employed to optimize the operating voltage of a device. At a
given frequency, the hardware monitors dynamic factors and either
makes a suggestion for how much to adjust a voltage for the
current frequency, or it automatically adjusts the voltage

In the former case, an AVS driver will call
dev_pm_opp_modify_voltage() and update the voltage for the
particular OPP the CPUs are using. Add an OPP notifier to

Subject: [PATCH 58/69] clk: qcom: Always add factor clock for xo clocks
Currently the RPM/RPM-SMD clock drivers do not register the xo clocks,
so we should always add factor clock. When we later add xo clocks support
into the drivers, we should update this function to skip registration.
By doing so we avoid any DT dependencies.

Subject: [PATCH 60/69] HACK: arch: arm: force ZRELADDR on arch-qcom
ARCH_QCOM is using the ARCH_MULTIPLATFORM option, as now recommended
on most ARM architectures. This automatically calculate ZRELADDR by
masking PHYS_OFFSET with 0xf8000000.
However, on IPQ806x, the first ~20MB of RAM is reserved for the hardware
network accelerators, and the bootloader removes this section from the
layout passed from the ATAGS (when used).
For newer bootloader, when DT is used, this is not a problem, we just
reserve this memory in the device tree. But if the bootloader doesn't
have DT support, then ATAGS have to be used. In this case, the ARM
decompressor will position the kernel in this low mem, which will not be
in the RAM section mapped by the bootloader, which means the kernel will
freeze in the middle of the boot process trying to map the memory.
As a work around, this patch allows disabling AUTO_ZRELADDR when
ARCH_QCOM is selected. It makes the zImage usage possible on bootloaders
which don't support device-tree, which is the case on certain early
IPQ806x based designs.

Subject: [PATCH] ipq8064: tsens: Support for configurable interrupts
Provide support for adding configurable high and
configurable low trip temperatures. An interrupts is
also triggerred when these trip points are hit. The
interrupts can be activated or deactivated from sysfs.
This functionality is made available only if
CONFIG_THERMAL_WRITABLE_TRIPS is defined.

Subject: [PATCH 67/69] generic: Mangle bootloader's kernel arguments
The command-line arguments provided by the boot loader will be
appended to a new device tree property: bootloader-args.
If there is a property "append-rootblock" in DT under /chosen
and a root= option in bootloaders command line it will be parsed
and added to DT bootargs with the form: <append-rootblock>XX.
Only command line ATAG will be processed, the rest of the ATAGs
sent by bootloader will be ignored.
This is usefull in dual boot systems, to get the current root partition
without afecting the rest of the system.

(dw_pcie_host_init) from [] (qcom_pcie_probe+0x20c/0x2e4)
pcie_phy_clk is generated for PCIe controller itself and the
GCC controls its branch operation. This error is coming since
the assert operations turn off the parent clock before branch
clock. Now this patch moves clk_disable_unprepare before assert
operations.
Similarly, during probe function, the clock branch operation
should be done after dessert operation. Currently, it does not
generate any error since bootloader enables the pcie_phy_clk
but the same error is coming during probe, if bootloader
disables pcie_phy_clk.

Subject: pinctrl: qcom: use scm_call to route GPIO irq to Apps
For IPQ806x targets, TZ protects the registers that are used to
configure the routing of interrupts to a target processor.
To resolve this, this patch uses scm call to route GPIO interrupts
to application processor. Also the scm call interface is changed.

Subject: [PATCH] mtd: nand: add Winbond manufacturer and chip
This patch adds the W25N01GV NAND to the table of
known devices. Without this patch the device gets detected:
nand: device found, Manufacturer ID: 0xef, Chip ID: 0xaa
nand: Unknown NAND 256MiB 1,8V 8-bit
nand: 256 MiB, SLC, erase size: 64 KiB, page size: 1024, OOB size : 16
Whereas the u-boot identifies it as:
spi_nand: spi_nand_flash_probe SF NAND ID 00:ef:aa:21
SF: Detected W25N01GV with page size 2 KiB, total 128 MiB
Due to the page size discrepancy, it's impossible to attach
ubi volumes on the device.

Subject: mtd: spi-nor: add mx25l25635f with SECT_4K
This patch fixes an issue with the creation of the
ubi volume on the AVM FRITZ!Box 4040. The mx25l25635f
and mx25l25635e support SECT_4K which will set the
erase size to 4K. This is used by ubi to calculate
VID header offsets. Without this, uboot and linux
disagrees about the layout and refuse to attach
the ubi volume created by the other.
