dee3978e96 arm64: dts: renesas: salvator-x: Add DU external dot clock sources
The DU1 and DU2 external dot clocks are fixed frequency clock generators
running at 33MHz, while the DU0 and DU3 external dot clocks are
generated by an I2C-controlled programmable clock generator.

All those clock generators are available on both the H3 and M3-W
Salvator-X boards. Add them to the salvator-x.dtsi file.

The Renesas ULCB development board can be equipped with either an R-Car
H3 or M3-W SiP, which are pin-compatible.  Both boards use different
DTBs.

Reduce duplication by extracting common ULCB board support into its own
.dtsi file.  References to SoC-specific clocks are handled through cpp
definitions.  Sort device nodes while at it.

For H3ULCB, there are no functional changes.

For M3ULCB, the following new devices are now described in DT:
  - External audio, CAN, and PCIe clocks,
  - CS2000 clock generator,
  - AK4613 Audio Codec.

3e7a5b3c8d arm64: dts: r8a7795: update PFC node name to pin-controller
The device trees for Renesas SoCs use either pfc or pin-controller as the
node name for the PFC device. This patch is intended to take a step towards
unifying the node name used as pin-controller which appears to be the more
generic of the two and thus more in keeping with the DT specs.

My analysis is that this is a user-visible change to the extent that kernel
logs, and sysfs entries change from e6060000.pfc and pfc@e6060000 to
e6060000.pin-controller and pin-controller@e6060000.

b5a8ffad0e arm64: dts: r8a7795: Tidyup Audio-DMAC channel for DVC
Current	Audio-DMAC is assigned "rx" as Audio-DMAC0, "tx" as Audio-DMAC1.
Thus, DVC "tx" should be assigned as Audio-DMAC1, instead of Audio-DMAC0.

Because of this, current platform board (using SRC/DVC/SSI)
Playback/Capture both will use same Audio-DMAC0
(but it depends on audio data path).

First note is that this "rx" and "tx" are from each IP point,
it doesn't mean Playback/Capture.
Second note is that Audio DMAC assigned on DT is only for
Audio-DMAC, Audio-DMAC-peri-peri has no entry.

=> Audio-DMAC
-> Audio-DMAC-peri-peri

7d73a4da26 arm64: dts: r8a7795: salvator-x: Set drive-strength for ravb pins
The EthernetAVB should not depend on the bootloader to setup correct
drive-strength values. Values for drive-strength where found by
examining the registers after the bootloader has configured the
registers and successfully used the EthernetAVB.

57a4fd420c arm64: dts: r8a7796: Remove unit-address and reg from integrated cache
The Cortex-A57 cache controller is an integrated controller, and thus
the device node representing it should not have a unit-addresses or reg
property.

b3f26910c0 arm64: dts: r8a7796: Upgrade to PSCI v1.0 to support Suspend-to-RAM
>From PSCI v1.0, Suspend-to-RAM is supported via SYSTEM_SUSPEND PSCI
function call. Hence, upgrade PSCI version for R-Car M3-W to support
Suspend-to-RAM.

The Suspend-to-RAM is highly dependent on ARM Trusted Firwmare support
since necessary callback functions will be registered after a query
to ARM Trusted Firmware about SYSTEM_SUSPEND support.

Since PSCI v1.0 is backward compatible with PSCI v0.2, CPU Hotplug and
CPUIdle should be able to work normally with this change.
