[PATCH v4 0/2] arm64: dts: Add SYSREG nodes for FSD SoC

[PATCH v4 0/2] arm64: dts: Add SYSREG nodes for FSD SoC

[Sriranjani P]

FSD has few system controller register blocks. This patch series intends to
add support of device node for system controller registers group that
resides in PERIC, FSYS0, FSYS1 and CAM blocks of FSD SoC. As these will
be used by PCIE, EQoS and CSI module. Patches for adding support for PCIE,
EQoS and CSI are already under review at [1], [2] and [3].

Also this patch series add required DT bindings for such system controller
of FSD SoC.

[1]: https://lkml.org/lkml/2022/11/21/463
[2]: https://lkml.org/lkml/2022/11/4/420
[3]: https://lkml.org/lkml/2022/11/20/363

These changes are made on top of Krzysztof's patches [4] posted as part of
splitting Samsung Exynos SoC SYSREG bindings to own file.

[4]: https://lkml.org/lkml/2022/11/25/370

Changes since v3:
1. As per update from Krzysztof, add dedicated compatibles for sysreg found
on FSD SoC in the exynos-sysreg.yaml file.
2. Add CAM block sysreg changes in the dtsi file and respective compatible
in binding document.

Changes since v2:
1. Updated compatibles as per improvements suggested by Krzysztof.

Changes since v1:
1. Fixed SoB in [PATCH 1/2] dt-bindings: mfd: syscon: Add tesla compatible
found on FSD SoC.
2. Address review comments from Krzysztof on [PATCH 2/2] and aligned sysreg
node near to respective blocks sorted in order of unit address.

If you ping me, then:
1. Pinging after a week is a bit too fast. Standard is 2 weeks.
2. It is too late in the cycle for me to pick it up. I will take it
after the merge window. Anything sent after rc5 usually misses upcoming
merge window.

Best regards,
Krzysztof
