Merge tag 'samsung-dt64-6.20' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux into soc/dt
Samsung DTS ARM64 changes for v6.20
1. ExynosAutov920:
- Add MFD clock controller node.
2. Google GS101:
- Add True Random Number Generator (TRNG) and OTP nvmem nodes.
- Correct the PMU (Power Management Unit) compatibles by dropping
fallback to syscon. The PMU on Samsung devices serves the role of
syscon, however on GS101 it cannot be used via standard Linux syscon
interface, because register accesses require custom regmap. It was
simply never correctly working with "syscon" compatible fallback.
- Add phandles to System Registers SYSREG blocks in clock controllers,
necessary for enabling automatic clock control later.
