Consider a message size limit when calculating the maximum amount
of data that can be read.
The message size limit has been introduced with 4.9, so cc it
to stable.

Subject: [PATCH 2/8] spi/bcm63xx: make spi subsystem aware of message size
limits
The bcm63xx LS SPI controller does not allow manual control of the CS
lines and will toggle it automatically before after sending data, so we
are limited to messages that fit in the FIFO buffer. Since the CS lines
aren't available as GPIOs either, we will need to make slave drivers
aware of this limitation and handle it accordingly.

Subject: [PATCH] mdio_bus: Issue GPIO RESET to PHYs.
Some boards [1] leave the PHYs at an invalid state
during system power-up or reset thus causing unreliability
issues with the PHY which manifests as PHY not being detected
or link not functional. To fix this, these PHYs need to be RESET
via a GPIO connected to the PHY's RESET pin.
Some boards have a single GPIO controlling the PHY RESET pin of all
PHYs on the bus whereas some others have separate GPIOs controlling
individual PHY RESETs.
In both cases, the RESET de-assertion cannot be done in the PHY driver
as the PHY will not probe till its reset is de-asserted.
So do the RESET de-assertion in the MDIO bus driver.

Subject: [PATCH] net: phy: Call bus->reset() after releasing PHYs from reset
The API convention makes it that a given MDIO bus reset should be able
to access PHY devices in its reset() callback and perform additional
MDIO accesses in order to bring the bus and PHYs in a working state.
Commit 69226896ad63 ("mdio_bus: Issue GPIO RESET to PHYs.") broke that
contract by first calling bus->reset() and then release all PHYs from
reset using their shared GPIO line, so restore the expected
functionality here.
Fixes: 69226896ad63 ("mdio_bus: Issue GPIO RESET to PHYs.")

Subject: [PATCH 2/6] bcm63xx_enet: do not write to random DMA channel on
BCM6345
The DMA controller regs actually point to DMA channel 0, so the write to
ENETDMA_CFG_REG will actually modify a random DMA channel.
Since DMA controller registers do not exist on BCM6345, guard the write
with the usual check for dma_has_sram.

Subject: [PATCH 3/6] bcm63xx_enet: do not rely on probe order
Do not rely on the shared device being probed before the enet(sw)
devices. This makes it easier to eventually move out the shared
device as a dma controller driver (what it should be).

bcm63xx USB gadget driver to arch/mips/bcm63xx/usb-common.c in
preparation for adding support for OHCI and EHCI host controllers which
will also touch the USB private register.

Subject: [PATCH 04/11] MIPS: BCM63XX: add OHCI/EHCI configuration bits to
common USB code
This patch updates the common USB code touching the USB private
registers with the specific bits to properly enable OHCI and EHCI
controllers on BCM63xx SoCs. As a result we now need to protect access
to Read Modify Write sequences using a spinlock because we cannot
guarantee that any of the exposed helper will not be called
concurrently.

symbol
This configuration symbol can be used by CPUs supporting the on-chip
OHCI controller, and ensures that all relevant OHCI-related
configuration options are correctly selected. So far, OHCI support is
available for the 6328, 6348, 6358 and 6358 SoCs.

Subject: [PATCH 08/11] MIPS: BCM63XX: introduce BCM63XX_EHCI configuration
symbol
This configuration symbol can be used by CPUs supporting the on-chip
EHCI controller, and ensures that all relevant EHCI-related
configuration options are selected. So far BCM6328, BCM6358 and BCM6368
have an EHCI controller and do select this symbol. Update
drivers/usb/host/Kconfig with BCM63XX to update direct unmet
dependencies.

Subject: [PATCH 09/11] MIPS: BCM63XX: add support for the on-chip EHCI
controller
Broadcom BCM63XX SoCs include an on-chip EHCI controller which can be
driven by the generic ehci-platform driver by using specific power
on/off/suspend callbacks to manage clocks and hardware specific
configuration.

Make the behaviour of clk_get_rate consistent with common clk's
clk_get_rate by accepting NULL clocks as parameter. Some device
drivers rely on this, and will cause an OOPS otherwise.

partitions {
compatible = "fixed-partitions";

reg = <0x0 0x10000>;
label = "cfe";
read-only;
};

Subject: [PATCH] mtd: bcm63xxpart: move imagetag parsing to its own parser
Move the bcm963xx Image Tag parsing into its own partition parser. This
Allows reusing the parser with different full flash parsers.
While moving it, rename it to bcm963* to better reflect it isn't chip
but board specific.

I tried to keep the code as-is, to keep the changes as small as
possible.
One side effect is that the partitions get renumbered, which means any
root=/dev/mtdblock* will now point to the wrong mtd device. But since
bcm963xx boards will require these hardcoded in the kernel commandline
anyway this should b a non issue, as it can be easily updated.
There is no such thing in the mips/bcm63xx defconfig, so nothing to update
there.

Subject: [PATCH 03/16] pinctrl: add a pincontrol driver for BCM6328
Add a pincontrol driver for BCM6328. BCM628 supports muxing 32 pins as
GPIOs, as LEDs for the integrated LED controller, or various other
functions. Its pincontrol mux registers also control other aspects, like
switching the second USB port between host and device mode.

Subject: [PATCH 05/16] pinctrl: add a pincontrol driver for BCM6348
Add a pincotrol driver for BCM6348. BCM6348 allow muxing five groups of
up to ten gpios into fourteen potential functions. It does not allow
muxing individual pins. Some functions require more than one group to be
muxed to the same function.

Subject: [PATCH 07/16] pinctrl: add a pincontrol driver for BCM6358
Add a pincotrol driver for BCM6358. BCM6358 allow overlaying different
functions onto the GPIO pins. It does not support configuring individual
pins but only whole groups. These groups may overlap, and still require
the directions to be set correctly in the GPIO register. In addition the
functions register controls other, not directly mux related functions.

+- compatible: Must be "brcm,bcm6362-pinctrl"
+- reg: Register specifiers of dirout, dat, led, mode, ctrl, basemode registers.
+- reg-names: Must be "dirout", "dat", "led", "mode", "ctrl", "basemode".
+- gpio-controller: Identifies this node as a GPIO controller.
+- #gpio-cells: Must be <2>.

Subject: [PATCH 09/16] pinctrl: add a pincontrol driver for BCM6362
Add a pincotrol driver for BCM6362. BCM6362 allows muxing individual
GPIO pins to the LED controller, to be available by the integrated
wifi, or other functions. It also supports overlay groups, of which
only NAND is documented.

+* Broadcom BCM63268 pin controller
+
+Required properties:
+- compatible: Must be "brcm,bcm6362-pinctrl".
+- reg: Register specifiers of dirout, dat, led, mode, ctrl, basemode registers.
+- reg-names: Must be "dirout", "dat", "led", "mode", "ctrl", "basemode".
+- gpio-controller: Identifies this node as a GPIO controller.
+- #gpio-cells: Must be <2>.
+
+Example:
+
+pinctrl: pin-controller@100000c0 {
+ compatible = "brcm,bcm63268-pinctrl";
+ reg = <0x100000c0 0x8>,

Subject: [PATCH 13/16] pinctrl: add a pincontrol driver for BCM63268
Add a pincontrol driver for BCM63268. BCM63268 allows muxing GPIOs
to different functions. Depending on the mux, these are either single
pin configurations or whole pin groups.

Subject: [PATCH] USB: EHCI: allow limiting ports for ehci-platform
In the same way as the ohci platform driver allows limiting ports,
enable the same for ehci. This prevents a mismatch in the available
ports between ehci/ohci on USB 2.0 controllers.
This is needed if the USB host controller always reports the maximum
number of ports regardless of the number of available ports (because
one might be set to be usb device).

+Broadcom BCM6345 Level 1 periphery interrupt controller
+
+This block is a interrupt controller that is typically connected directly
+to one of the HW INT lines on each CPU. Every BCM63XX xDSL chip since
+BCM6345 has contained this hardware.
+
+Key elements of the hardware design include:
+
+- 32, 64, or 128 incoming level IRQ lines
+
+- All onchip peripherals are wired directly to an L2 input
+
+- A separate instance of the register set for each CPU, allowing individual
+ peripheral IRQs to be routed to any CPU
+
+- No atomic mask/unmask operations
+
+- No polarity/level/edge settings
+
+- No FIFO or priority encoder logic; software is expected to read all
+ 1-4 status words to determine which IRQs are pending
+
+Required properties:
+
+- compatible: Should be "brcm,bcm6345-periph-intc".
+- reg: Specifies the base physical address and size of the registers.
+ Multiple register addresses may be specified, and must match the amount of
+ parent interrupts.
+- interrupt-controller: Identifies the node as an interrupt controller.
+- #interrupt-cells: Specifies the number of cells needed to encode an interrupt
+ source, should be 1.
+- interrupt-parent: Specifies the phandle to the parent interrupt controller
+ this one is cascaded from.
+- interrupts: Specifies the interrupt line(s) in the interrupt-parent controller
+ node, valid values depend on the type of parent interrupt controller.
+ Multiple lines are used to route interrupts to different cpus, with the first
+ assumed to be for the boot CPU.
+
+Example:
+
+periph_intc: interrupt-controller@f0406800 {
+ compatible = "brcm,bcm6345-periph-intc";
+ reg = <0x10000020 0x10>, <0x10000030 0x10>;
+
+ interrupt-controller;
+ #interrupt-cells = <1>;
+
+ interrupt-parent = <&cpu_intc>;
+ interrupts = <2>, <3>;
+};

+Broadcom BCM6345-style external interrupt controller
+
+Required properties:
+
+- compatible: Should be "brcm,bcm6345-ext-intc" or "brcm,bcm6318-ext-intc".
+- reg: Specifies the base physical addresses and size of the registers.
+- interrupt-controller: identifies the node as an interrupt controller.
+- #interrupt-cells: Specifies the number of cells needed to encode an interrupt
+ source, Should be 2.
+- interrupt-parent: Specifies the phandle to the parent interrupt controller
+ this one is cascaded from.
+- interrupts: Specifies the interrupt line(s) in the interrupt-parent controller
+ node, valid values depend on the type of parent interrupt controller.
+
+Optional properties:
+
+- brcm,field-width: Size of each field (mask, clear, sense, ...) in bits in the
+ register. Defaults to 4.
+
+Example:
+
+ext_intc: interrupt-controller@10000018 {
+ compatible = "brcm,bcm6345-ext-intc";
+ interrupt-parent = <&periph_intc>;
+ #interrupt-cells = <2>;
+ reg = <0x10000018 0x4>;
+ interrupt-controller;
+ interrupts = <24>, <25>, <26>, <27>;
+};

From 4fd286c3e5a5bebab0391cf1937695b3ed6721a3 Mon Sep 17 00:00:00 2001
From: Jonas Gorski <jogo@openwrt.org>
Date: Sun, 30 Nov 2014 20:20:30 +0100
Subject: [PATCH 4/5] MIPS: BCM63XX: wire up BCM6358's external interrupts 4
and 5
Due to the external interrupts being non consecutive, the previous
implementation did not support them. Now that we treat both registers
as separate irq controllers, there is no such limitation anymore and
we can expose them for drivers to use.

The DSL-less BCM6368 variant BCM6367 uses a different chip id. Apart
from missing DSL, there is no difference to BCM6368, so treat it such.

Subject: [PATCH 52/56] MIPS: BCM63XX: fixup mapped SPI flash access on boot
Some bootloaders leave the flash access in an invalid state with dual
read enabled; fix it by disabling it and falling back to simple fast
reads.

Subject: [PATCH 42/44] MIPS: BCM63XX: allow building support for more than one
board type
Use the arguments passed to the kernel to detect being booted with
CFE as the indicator for bcm963xx board support, allowing the
non presence of CFE_EPTSEAL to assume a different board type.

Subject: [PATCH 01/10] MIPS: BCM63XX: move fallback sprom support into its own
unit
In preparation for enhancing it, move it into its own file. Require a
mac address to be passed as the argument to always "reserve" the mac
regardless of the inclusion state of SSB.

Subject: [PATCH 03/10] MIPS: BCM63XX: make fallback sprom optional
Some devices do not provide enough mac addresses to populate wifi in
addition to ethernet.
Use having pci enabled as a rough heuristic which boards should have it
enabled.

Subject: [PATCH 09/10] MIPS: BCM63XX: allow board files to provide sprom
fixups
Allow board_info files to supply fixups for the base sproms to adapt
them to the actual used sprom contents in case they do not use the
default ones.
