soc: renesas: r8a779a0-sysc: Fix A2DP1 and A2CV[2357] PDR values

2022-08-17T12:40:28Z

[ Upstream commit bccceabb92ce8eb78bbf2de08308e2cc2761a2e5 ] The PDR values for the A2DP1 and A2CV[2357] power areas on R-Car V3U are incorrect (copied-and-pasted from A2DP0 and A2CV[0146]). Fix them.

soc: renesas: Kconfig: Introduce ARCH_RZG2L config option

2022-02-24T12:53:25Z

The Renesas RZ/G2L, RZ/G2LC, RZ/G2UL and RZ/V2L SoCs have identical IP blocks for which drivers are common. To avoid updating the Kconfig files for drivers in common to each SoC, introduce the ARCH_RZG2L config option. The ARCH_RZG2L config option will be selected by the above mentioned SoCs, and the ARCH_RZG2L config option will be used as a dependency for the drivers in common. While at it, move PM and PM_GENERIC_DOMAINS under the ARCH_RZG2L config option instead of keeping it for individual SoCs.

soc: renesas: Kconfig: Explicitly select PM and PM_GENERIC_DOMAINS configs

2022-02-22T08:44:15Z

Explicitly select PM and PM_GENERIC_DOMAINS configs for ARCH_R9A07G044 and ARCH_R9A07G054 configs. PM and PM_GENERIC_DOMAINS configs are required for RZ/{G2L,V2L} SoC without these configs the SMARC EVK's won't boot.

soc: renesas: Consolidate product register handling

2021-11-30T08:42:00Z

Currently renesas_soc_init() scans the whole device tree up to three times, to find a device node describing a product register. Furthermore, the product register handling for the different variants is very similar, with the major difference being the location of the product bitfield inside the product register. Reduce scanning to a single pass using of_find_matching_node_and_match() instead. Switch to a common handling of product registers, by storing the intrinsics of each product register type in the data field of the corresponding match entry.
