For imx50-weim and imx6q-weim type of devices, there might a WEIM CS
space configuration register in General Purpose Register controller,
e.g. IOMUXC_GPR1 on i.MX6Q.
Depending on which configuration of the following 4 is chosen for given
system, IOMUXC_GPR1[11:0] should be set up as 05, 033, 0113 or 01111
correspondingly.
CS0(128M) CS1(0M) CS2(0M) CS3(0M)
CS0(64M) CS1(64M) CS2(0M) CS3(0M)
CS0(64M) CS1(32M) CS2(32M) CS3(0M)
CS0(32M) CS1(32M) CS2(32M) CS3(32M)
The patch creates a function for such type of devices, which scans
'ranges' property of WEIM node and build the GPR value incrementally.
Thus the WEIM CS GPR can be set up automatically at boot time.

The Xilinx XADC is a ADC that can be found in the series 7 FPGAs from Xilinx.
The XADC has a DRP interface for communication. Currently two different
frontends for the DRP interface exist. One that is only available on the ZYNQ
family as a hardmacro in the SoC portion of the ZYNQ. The other one is available
on all series 7 platforms and is a softmacro with a AXI interface. This binding
document describes the bindings for both of them since the bindings are very
similar.
Each of them needs:
* A address range where the registers are mapped
* An interrupt number for the device interrupt
* A clock. For the the ZYNQ hardmacro interface this is the modules PCAP
clock, for the AXI softmacro it is the AXI bus interface clock.
Additionally the bindings specify whether an external multiplexer is used and in
which mode it is used. The devicetree bindings also describe which external
channels are connected and in which configuration.

Add bindings for TI Async External Memory Interface (AEMIF) controller.
The Async External Memory Interface (EMIF16/AEMIF) controller is intended to
provide a glue-less interface to a variety of asynchronous memory devices like
ASRA M, NOR and NAND memory. A total of 256M bytes of any of these memories
can be accessed via 4 chip selects with 64M byte access per chip select.
We are not encoding CS number in reg property, it's memory partition number.
The CS number is encoded for Davinci NAND node using standalone property
"ti,davinci-chipselect" and we need to provide two memory ranges to it,
as result we can't encode CS number in "reg" for AEMIF child devices
(NAND/NOR/etc), as it will break bindings compatibility.
In this patch, NAND node is used just as an example of child node.

Add support for the MSIOF variant in the R-Car H2 (r8a7790) and M2
(r8a7791) SoCs.
Binding documentation:
- Add future-proof "renesas,msiof-<soctype>" compatible values,
- The default for "renesas,rx-fifo-size" is 256 on R-Car H2 and M2,
- "renesas,tx-fifo-size" and "renesas,rx-fifo-size" are deprecated for
soctype-specific bindings,
- Add example bindings.
Implementation:
- MSIOF on R-Car H2 and M2 requires the transmission of dummy data if
data is being received only (cfr. "Set SICTR.TSCKE to 1" and "Write
dummy transmission data to SITFDR" in paragraph "Transmit and Receive
Procedures" of the Hardware User's Manual).
- As RX depends on TX, MSIOF on R-Car H2 and M2 also lacks the RSCR
register (Receive Clock Select Register), and some bits in the RMDR1
(Receive Mode Register 1) and TMDR2 (Transmit Mode Register 2)
registers.
- Use the recently introduced SPI_MASTER_MUST_TX flag to enable support
for dummy transmission in the SPI core, and to differentiate from other
MSIOF implementations in code paths that need this.
- New DT compatible values ("renesas,msiof-r8a7790" and
"renesas,msiof-r8a7791") are added, as well as new platform device
names ("spi_r8a7790_msiof" and "spi_r8a7791_msiof").
- The default RX FIFO size is 256 words on R-Car H2 and M2.
This is loosely based on a set of patches from Takashi Yoshii
<takasi-y@ops.dti.ne.jp>.

Documentation:
- Add missing "interrupt-parent", "#address-cells", "#size-cells", and
"clocks" properties,
- Add missing default values for "num-cs", "renesas,tx-fifo-size" and
"renesas,rx-fifo-size",
- Add a reference to the pinctrl documentation.
Implementation:
- As "num-cs" is marked optional, provide a sensible default.

This driver supports the GPIO controller found in LSI ZEVIO SoCs.
It has been successfully tested on a TI nspire CX calculator.

Document what we (Laurent and I, following a mailing list dicussion)
believe are best practices for the polarity flag in a GPIO specifier.
While touching the doc, I made a few minor editing changes to other
areas.

Updates from Jean-Fracois for the TDA998x driver, which are on top of
the fixes you have previously pulled, except these changes aren't
intended for -rc, but the next merge window.
Several of these are issues of correctness - passing more correct HDMI
info packets, not reading registers in older chips documented as write
only (despite appearing to be read/write in later chips). Others are
code cleanups (using definitions rather than constants where we have
them already in the kernel).
Additional functionality is also added by way of optional support for
the IRQ from the TDA998x, which allows us to avoid busy-waiting for
the EDID reads.
* 'tda998x-devel' of git://ftp.arm.linux.org.uk/~rmk/linux-cubox:
drm/i2c: tda998x: always use the same device for all kernel messages
drm/i2c: tda998x: adjust the audio clock divider for S/PDIF
drm/i2c: tda998x: code optimization
drm/i2c: tda998x: remove the unused variable ca_i2s
drm/i2c: tda998x: make the audio code more readable
drm/i2c: tda998x: use irq for connection status and EDID read
drm/i2c: tda998x: always enable EDID read IRQ
drm/i2c: tda998x: add DT documentation
drm/i2c: tda998x: add DT support
drm/i2c: tda998x: don't read write-only registers
drm/i2c: tda998x: don't freeze the system at audio startup time
drm/i2c: tda998x: change probe message origin
drm/i2c: tda998x: code cleanup
drm/i2c: tda998x: clean up error chip version checking
drm/i2c: tda998x: check more I/O errors
drm/i2c: tda998x: simplify the i2c read/write functions
drm/i2c: tda998x: use ALSA IEC958 definitions and update audio frequency
drm/i2c: tda998x: add the active aspect in HDMI AVI frame
drm/i2c: tda998x: use HDMI constants
This reverts tlv320aic32x4 as compatible for tlv320aic3x as it has its
own bindings now.
