soc: renesas: Move power-domain drivers to the genpd dir

2023-07-14T08:40:56+00:00

To simplify with maintenance let's move the renesas power-domain drivers to the new genpd directory. Going forward, patches are intended to be managed through a separate git tree, according to MAINTAINERS. Cc: Geert Uytterhoeven Cc: Magnus Damm Cc: Signed-off-by: Ulf Hansson

soc: renesas: rcar-sysc: Optimize rcar_sysc_area struct sizes

2022-06-13T09:43:50+00:00

Reduce the sizes of the rcar_sysc_area and rcar_gen4_sysc_area structures: - parent is in the range [-1..32] or [-1..64], so s8 is sufficient, - flags needs just 3 bits (for now), so u8 is plenty. This reduces kernel size by: - 288 bytes for an R-Car Gen1+Gen2 kernel (arm32), - 1772 bytes for an R-Car Gen3+Gen4 kernel (arm64).

soc: renesas: rcar-sysc: Add R8A77961 support

2019-11-01T13:25:53+00:00

Add support for the power areas in the Renesas R-Car M3-W+ (R8A77961) SoC to the R-Car System Controller driver. R-Car M3-W+ (aka R-Car M3-W ES3.0) is very similar to R-Car M3-W (R8A77960), which allows for both SoCs to share a driver: - R-Car M3-W+ lacks the A2VC power area, so its area must be nullified, - The existing support for the SYSCEXTMASK register added in commit 9bd645af9d2a49ac ("soc: renesas: r8a7796-sysc: Fix power request conflicts") applies to ES3.0 and later only. As R-Car M3-W+ uses a different compatible value, differentiate based on that, instead of on the ES version. Based on a patch in the BSP by Dien Pham .

soc: renesas: Rename SYSC_R8A7796 to SYSC_R8A77960

Rename CONFIG_SYSC_R8A7796 for R-Car M3-W (R8A77960) to CONFIG_SYSC_R8A77960, to avoid confusion with R-Car M3-W+ (R8A77961), which will use CONFIG_SYSC_R8A77961. Rename r8a7796_sysc_info and r8a7796_sysc_init for consistency.
