Merge tag 'samsung-drivers-6.19' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux into soc/drivers

Samsung SoC drivers for v6.19

1. ChipID driver: Add support for identifying Exynos8890 and Exynos9610.

2. PMU driver: Allow specifying list of valid registers for the custom
   regmap used on Google GS101 SoC.  The PMU (Power Management Unit) on
   that SoC uses more complex access to registers than simple MMIO and
   invalid registers trigger aborts halting the system.

3. Few minor cleanups.

4. Several new bindings for compatible devices.

* tag 'samsung-drivers-6.19' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux:
  dt-bindings: soc: samsung: exynos-pmu: allow mipi-phy subnode for Exynos7870 PMU
  soc: samsung: exynos-chipid: use a local dev variable
  dt-bindings: soc: samsung: exynos-sysreg: add gs101 hsi0 and misc compatibles
  dt-bindings: soc: samsung: exynos-sysreg: add power-domains
  soc: samsung: gs101-pmu: implement access tables for read and write
  soc: samsung: exynos-pmu: move some gs101 related code into new file
  soc: samsung: exynos-pmu: allow specifying read & write access tables for secure regmap
  dt-bindings: samsung: exynos-sysreg: add exynos7870 sysregs
  soc: samsung: exynos-chipid: add exynos8890 SoC support
  dt-bindings: hwinfo: samsung,exynos-chipid: add exynos8890-chipid compatible
  dt-bindings: soc: samsung: exynos-pmu: add exynos8890 compatible
  soc: samsung: exynos-pmu: Annotate online/offline functions with __must_hold
  soc: samsung: exynos-chipid: Add exynos9610 SoC support
  dt-bindings: hwinfo: samsung,exynos-chipid: add exynos9610 compatible
  dt-bindings: soc: samsung: exynos-sysreg: Add Exynos990 PERIC0/1 compatibles
