This patch removes s5p64x0 related spi because of no more support for
s5p64x0 SoCs. Meanwhile, cleanup SPI DT bindings for s5p6440-spi, it
should be s5p64x0-spi instead.

4a8573abe9 spi: qup: Remove chip select function
This patch removes the chip select function.  Chip select should instead be
supported using GPIOs, defining the DT entry "cs-gpios", and letting the SPI
core assert/deassert the chip select as it sees fit.

The chip select control inside the controller is buggy.  It is supposed to
automatically assert the chip select based on the activity in the controller,
but it is buggy and doesn't work at all.  So instead we elect to use GPIOs.

Make FSL eSPI CSnBEF and CSnAFT fields in ESPI_SPMODEn registers
(n=0,1,2,3) configurable through device tree.

CSnBEF is the chip select setup time.  It's the delay in bits from the
activation of chip select pin to the first clock for data frame.

CSnAFT is the chip select hold time.  It's the delay in bits from the
last clock for data frame to the deactivation of chip select pin.

The FSL eSPI driver hardcodes CSnBEF and CSnAFT to 0.  Need to set
them to a different value for some device.

beb74bb087 spi: sh-msiof: Add support for R-Car H2 and M2
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>.

b5f6517948 spi: sunxi: Add Allwinner A10 SPI controller driver
The older Allwinner SoCs (A10, A13, A10s and A20) all have the same SPI
controller.

Unfortunately, this SPI controller, even though quite similar, is significantly
different from the recently supported A31 SPI controller (different registers
offset, split/merged registers, etc.). Supporting both controllers in a single
driver would be unreasonable, hence the addition of a new driver.

Like its more recent counterpart, it supports DMA, but the driver only does PIO
until we have a dmaengine driver for this platform.

ed520c90b3 ARM: tegra: document use of standard DMA DT bindings
Update all the Tegra DT bindings to require the standard dmas/dma-names
properties rather than non-standard nvidia,dma-request-selector property.

This is a DT-ABI-incompatible change. It is the second of two changes
required for me to consider the Tegra DT bindings as stable, the other
being the previous conversion to the common reset bindings.

07999587b7 ARM: tegra: document reset properties in DT bindings
Update all the Tegra DT bindings to require resets/reset-names properties
where the HW module has reset inputs. Remove any entries from clocks or
clock-names that were only required to identify reset inputs, rather than
referring to real clocks.

This is a DT-ABI-incompatible change. It is the first of two changes
required for me to consider the Tegra DT bindings as stable, the other
being conversion to the common DMA DT bindings.

d8f64797c5 ARM: tegra: add missing clock documentation to DT bindings
Many of the Tegra DT binding documents say nothing about the clocks or
clock-names properties, yet those are present and required in DT files.
This patch simply updates the documentation file to match the implicit
definition of the binding, based on real-world DT content.

All Tegra bindings that mention clocks are updated to have consistent
wording and formatting of the clock-related properties.

ba1271bb05 spi: gpio: clarify gpio chipselect language
Commit 7431798490 (of_spi: add generic binding support to specify cs gpio)
introduced generic binding for gpio chip-select. The cs_gpio struct field,
however, is an internal implementation detail of the Linux SPI subsystem, and
should not be mentioned in the device tree binding documentation. Mention the
previously defined cs-gpios master node property instead.
