From f05be589ff32e87821b86845625ed3d402d37dc7 Mon Sep 17 00:00:00 2001

Subject: [PATCH] mfd: axp20x: Add AXP22x PMIC support
Add support for the AXP22x PMIC devices to the existing AXP20x driver.
This includes the AXP221 and AXP223, which are identical except for
the external data bus. Only AXP221 is added for now. AXP223 will be
added after it's Reduced Serial Bus (RSB) interface is supported.
AXP22x defines a new set of registers, power supplies and regulators,
but most of the API is similar to the AXP20x ones.
A new irq chip definition is used, even though the available interrupts
on AXP22x is a subset of those on AXP20x. This is done so the interrupt
numbers match those on the datasheet.
This patch only enables the interrupts, system power-off function, and PEK
sub-device. The regulator driver must first support different variants
before we enable it from the mfd driver.

Subject: [PATCH] regulator: axp20x: Prepare support for multiple AXP chip
families
Rework the AXP20X_ macros and probe function to support the several chip
families, so that each family can define it's own set of regulators.

Subject: [PATCH] regulator: axp20x: Add support for AXP22X regulators
Add AXP22X regulator definitions and variant id associations.
This introduces a new "switch" type output for one of the regulators.
It is a switchable secondary output of one regulator, with the same
voltage level as the primary output.

nand_scan_tail
Take ECC initialization code portion out of nand_scan_tail so that we can
re-use this implementation.
This commit only moves some code around and makes no functional changes.

Subject: [PATCH] mtd: nand: Add DT NAND partition parser
Add a of_nandpart_parse function to help parsing NAND partitions from DT.
This function should be called from NAND controller drivers just after the
nand_scan_tail in place of mtd_device_parse_register.
The caller can specify a parser function to retrieve HW specific
informations from the DT.

Subject: [PATCH] mtd: nand: Add page status table (pst)
Page status table is an byte array storing pages status.
It defines 3 status:
- unknown: the page has not been read yet and we do not know its current
state
- empty: the page contains only FFs
- filled: the page has been filled with data
Care must be taken: an empty page does not mean it can be written, because
it might have already been written with only FFs.
These page status are useful to check wether the controller should try to
correct errors (using ECC) or a derandomize data (using a randomizer
block).

Subject: [PATCH] mtd: nand: Introduce a randomizer layer in the NAND framework
This patch introduce a new layer in the NAND framework to support both HW
and SW randomizers.
This randomization is required on some MLC/TLC NAND chips which do not
support large islands of same patterns.
The randomizer layer defines a nand_rnd_ctrl struct which is intended to
be used by NAND core functions or NAND drivers to randomize/derandomize
data stored on NAND chips.
The implementation can implement any of these functions:
- config: prepare a random transfer to/from the NAND chip
- write_buf: randomize and write data to the NAND chip
- read_buf: read and derandomize data from the NAND chip
read/write_buf functions are always called after a config call.
The config call specify the page, the column within the page and the action
that will take place after the config (either read or write).
If column is set to -1, the randomizer is disabled.
If page is set to -1, we keep working on the same page.
The randomizer layer provides helper functions that choose wether the
randomizer or the chip read/write_buf should be used.

Subject: [PATCH] mtd: nand: nand_decode_ext_id(): Fill in ecc strength and
size for Samsung
On some nand controllers with hw-ecc the controller code wants to know the
ecc strength and size and having these as 0, 0 is not accepted.
Specifying these in devicetree is possible but undesirable as the nand
may be different in different production runs of the same board, so it
is better to get this info from the nand id where possible.
This commit adds code to read the ecc strength and size from the nand for
Samsung extended-id nands. This code is based on the info for the 5th
id byte in the datasheets for the following Samsung nands: K9GAG08U0E,
K9GAG08U0F, K9GAG08X0D, K9GBG08U0A, K9GBG08U0B. These all use these bits
in the exact same way.

Subject: [PATCH] mtd: nand: sunxi: Add NAND_BBT_CREATE_EMPTY to bbt_options
The ftl format used by the Allwinner Android kernels, with which most
Allwinnner devices ship, overrides the factory bad block markers, and
fills the oob data with a pattern which causes a lot of false bad block
positives, so when we first create a bbt table, start with an empty one
to avoid marking a ton of blocks as bad from the start.

Subject: [PATCH] nand: sunxi: fix write to USER_DATA reg
The USER_DATA register cannot be updated with readb on A13 SoCs, thus
triggering a bug when using memcpy_toio on this register.
Use writel (plus a temporary variable to old the USER_DATA value) to
address that problem.

Subject: [PATCH] mmc: sunxi: Don't start commands while the card is busy
Some sdio wifi modules have not been working reliable with the sunxi-mmc
host code. This turns out to be caused by it starting new commands while
the card signals that it is still busy processing a previous command.
This commit fixes this, thereby fixing the wifi reliability issues on
the Cubietruck and other sunxi boards using sdio wifi.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This patch adds support for PLL2 and derivates on A10 revision B and
higher, as well as on sun5i and sun7i SoCs. As this PLL is only used for
audio and requires good accuracy, we only support two known good rates.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The module 1 type of clocks consist of a gate and a mux and are used on
the audio blocks to mux and gate the PLL2 outputs for AC97, IIS or
SPDIF. This commit adds support for them on the sunxi clock driver.

Subject: [PATCH] ASoC: sunxi: add support for the on-chip codec on early
Allwinner SoCs
The sun4i, sun5i and sun7i SoC families have a built-in codec, capable
of both audio capture and playback. This memory-mapped device can be fed
with audio data via the Allwinner DMA controller.

Subject: [PATCH] usb: musb: sunxi: Add support for the Allwinner sunxi musb
controller
This is based on initial code to get the Allwinner sunxi musb controller
supported by Chen-Yu Tsai and Roman Byshko.
This adds support for the Allwinner sunxi musb controller in both host only
and otg mode. Peripheral only mode is not supported, as no boards use that.
This has been tested on a cubietruck (A20 SoC) and an UTOO P66 tablet
(A13 SoC) with a variety of devices in host mode and with the g_serial gadget
driver in peripheral mode, plugging otg / host cables in/out a lot of times
in all possible imaginable plug orders.

+Required properties:
+ - compatible : "allwinner,sun4i-a10-musb"
+ - reg : mmio address range of the musb controller
+ - clocks : clock specifier for the musb controller ahb gate clock
+ - interrupts : interrupt to which the musb controller is connected
+ - interrupt-names : must be "mc"
+ - phys : phy specifier for the otg phy
+ - phy-names : must be "usb"
+ - dr_mode : Dual-Role mode must be "host" or "otg"

Subject: [PATCH] usb: musb: sunxi: Add support for musb controller in A31 SoC
The A31 SoC uses the same musb controller as found in earlier SoCs, but it
is hooked up slightly different. Its SRAM is private and no longer controlled
through the SRAM controller, and its reset is controlled via a separate
reset controller. This commit adds support for this setup.

Subject: [PATCH] ARM: dts: sun7i: add bluetooth module to CubieTruck DTS
The CubieTruck has an AMPAK AP6210 WiFi+Bluetooth module. The
Bluetooth part is a BCM20710 IC connected to UART2 in the A20
SoC. The IC also takes a 32.768 KHz low power clock input, a power
enable signal and a wake signal via GPIO.
The Bluetooth module supports out-of-band interrupt signaling via
GPIO, but this is not supported in this patch.
