Okay, so... this one is interesting. RGB LEDs are very common, and we
need to have some kind of support for them. Multicolor is for
arbitrary set of LEDs in one package, RGB is for LEDs that can produce
full range of colors. We do not have real multicolor LED that is not
RGB in the pipeline, so that one is disabled for now.
You can expect this saga to continue with next pull requests.

A fairly quiet release for SPI, nothing really going on in the core
although there's been quite a bit of driver related activity. This pull
request includes the addition of some shared code in drivers/memory for
the Renesas RPC-IF which is used by a newly added SPI driver, the memory
subsystem doesn't seem to have a fixed maintainer at the minute and this
seemed like the most sensible way to get that hardware supported.
- Quite a few cleanups and optimizations for the Altera, Qualcomm GENI,
sun6i and lantiq drivers.
- Several more GPIO descriptor conversions.
- Move the Cadence QuadSPI driver from drivers/mtd to drivers/spi.
- New support for Mediatek MT8192 and Renesas RPC-IF, R8A7742 and
R8A774e1.

IP core of the DW DMA controller may be synthesized with different
max burst length of the transfers per each channel. According to Synopsis
having the fixed maximum burst transactions length may provide some
performance gain. At the same time setting up the source and destination
multi size exceeding the max burst length limitation may cause a serious
problems. In our case the DMA transaction just hangs up. In order to fix
this lets introduce the max burst length platform config of the DW DMA
controller device and don't let the DMA channels configuration code
exceed the burst length hardware limitation.
Note the maximum burst length parameter can be detected either in runtime
from the DWC parameter registers or from the dedicated DT property.
Depending on the IP core configuration the maximum value can vary from
channel to channel so by overriding the channel slave max_burst capability
we make sure a DMA consumer will get the channel-specific max burst
length.

According to the DW APB DMAC data book the minimum burst transaction
length is 1 and it's true for any version of the controller since
isn't parametrised in the coreAssembler so can't be changed at the
IP-core synthesis stage. The maximum burst transaction can vary from
channel to channel and from controller to controller depending on a
IP-core parameter the system engineer activated during the IP-core
synthesis. Let's initialise both min_burst and max_burst members of the
DMA controller descriptor with extreme values so the DMA clients could
use them to properly optimize the DMA requests. The channels and
controller-specific max_burst length initialization will be introduced
by the follow-up patches.

This converts the two Freescale i.MX SPI drivers
Freescale i.MX (CONFIG_SPI_IMX) and Freescale i.MX LPSPI
(CONFIG_SPI_FSL_LPSPI) to use GPIO descriptors handled in
the SPI core for GPIO chip selects whether defined in
the device tree or a board file.
The reason why both are converted at the same time is
that they were both using the same platform data and
platform device population helpers when using
board files intertwining the code so this gives a cleaner
cut.
The platform device creation was passing a platform data
container from each boardfile down to the driver using
struct spi_imx_master from <linux/platform_data/spi-imx.h>,
but this was only conveying the number of chipselects and
an int * array of the chipselect GPIO numbers.
The imx27 and imx31 platforms had code passing the
now-unused platform data when creating the platform devices,
this has been repurposed to pass around GPIO descriptor
tables. The platform data struct that was just passing an
array of integers and number of chip selects for the GPIO
lines has been removed.
The number of chipselects used to be passed from the board
file, because this number also limits the number of native
chipselects that the platform can use. To deal with this we
just augment the i.MX (CONFIG_SPI_IMX) driver to support 3
chipselects if the platform does not define "num-cs" as a
device property (such as from the device tree). This covers
all the legacy boards as these use <= 3 native chip selects
(or GPIO lines, and in that case the number of chip selects
is determined by the core from the number of available
GPIO lines). Any new boards should use device tree, so
this is a reasonable simplification to cover all old
boards.
The LPSPI driver never assigned the number of chipselects
and thus always fall back to the core default of 1 chip
select if no GPIOs are defined in the device tree.
The Freescale i.MX driver was already partly utilizing
the SPI core to obtain the GPIO numbers from the device tree,
so this completes the transtion to let the core handle all
of it.
All board files and the core i.MX boardfile registration
code is augmented to account for these changes.
This has been compile-tested with the imx_v4_v5_defconfig
and the imx_v6_v7_defconfig.

The LP55xx driver is already using the of_gpio() functions to
pick a global GPIO number for "enable" from the device tree and
request the line. Simplify it by just using a GPIO descriptor.
Make sure to keep the enable GPIO line optional, change the
naming from "lp5523_enable" to "LP55xx enable" to reflect that
this is used on all LP55xx LED drivers.

This converts the s3c24xx LED driver to use GPIO descriptors
and also modify all board files to account for these changes
by registering the appropriate GPIO tables for each board.
The driver was using a custom flag to indicate open drain
(tristate) but this can be handled by standard descriptor
machine tables.
The driver was setting non-pull-up for the pin using the custom
S3C24xx GPIO API, but this is a custom pin control system used
by the S3C24xx and no generic GPIO function, so this has simply
been pushed back into the respective board files.

"I2C has quite some patches for you this time. I hope it is the move to

The big news is two new drivers (Nuvoton NPCM and Qualcomm CCI),
larger refactoring of the Designware, Tegra, and PXA drivers, the
Cadence driver supports being a slave now, and there is support to
instanciate SPD eeproms for well-known cases (which will be
user-visible because the i801 driver supports it), and some
devm_platform_ioremap_resource() conversions which blow up the
diffstat.
Note that I applied the Nuvoton driver quite late, so some minor fixup
patches arrived during the merge window. I chose to apply them right

Core changes:
- A new GPIO aggregator driver has been merged: this can
join a few select GPIO lines into a new aggregated GPIO
chip. This can be used for security: a process can be
granted access to only these lines, for example for
industrial control. Another way to use this is to
reexpose certain select lines to a virtual machine or
container.
- Warn if the gpio-line-names is too long in he DT parser
core.
- GPIO lines can now be looked up by line name in addition
to being looked up by offset.
New drivers:
- A new generic regmap GPIO driver has been merged. Too
many regmap drivers are starting to look like each other
so we need to create some common ground and try to move
drivers over to using that.
- The F7188X driver now supports F81865.
Driver improvements:
- Large improvements to the PCA953x expander, get multiple lines
and several cleanups.
- Large improvements to the DesignWare DWAPB driver, and Sergey
Semin has volunteered to maintain it.
- PL061 can now be built as a module, this is part of a bigger
effort to make the ARM platforms more modular.

One new platform gets added, the Realtek RTD1195, which is an older
Cortex-a7 based relative of the RTD12xx chips that are already supported
in arch/arm64. The platform may also be extended to support running
32-bit kernels on those 64-bit chips for memory-constrained machines.
In the Renesas shmobile platform, we gain support for "RZ/G1H" or R8A7742,
an eight-core chip based on Cortex-A15 and Cortex-A7 cores, originally
released in 2016 as one of the last high-end 32-bit designs.
There is ongoing cleanup for the integrator, tegra, imx, and omap2
platforms, with integrator getting very close to the goal of having
zero code in arch/arm/, and omap2 moving more of the chip specifics
from old board code into device tree files.
The Versatile Express platform is made more modular, with built-in
drivers now becoming loadable modules. This is part of a greater effort
for the Android OS to have a common kernel binary for all platforms and
any platform specific code in loadable modules.
The PXA platform drops support for Compulab's pxa2xx boards that had
rather unusual flash and PCI drivers but no known users remaining.
All device drivers specific to those boards can now get removed as
well.
Across platforms, there is ongoing cleanup, with Geert and Rob
revisiting some a lot of Kconfig options.

has_irq member of struct dwapb_port_property is used only in one place,
so, make it local test instead and remove from the structure.
This local test is using memchr_inv() which is quite efficient in comparison

This driver only creates a bunch of platform devices sharing resources
belonging to the PMC device. This is pretty much what MFD subsystem is
for so move the driver there, renaming it to intel_pmc_bxt.c which
should be more clear what it is.
MFD subsystem provides nice helper APIs for subdevice creation so
convert the driver to use those. Unfortunately the ACPI device includes
separate resources for most of the subdevices so we cannot simply call
mfd_add_devices() to create all of them but instead we need to call it
separately for each device.
The new MFD driver continues to expose two sysfs attributes that allow
userspace to send IPC commands to the PMC/SCU to avoid breaking any
existing applications that may use these. Generally this is bad idea so
document this in the ABI documentation.

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
This issue was found with the help of Coccinelle.
