2019-10-01soc: renesas: rcar-sysc: Remove unneeded inclusion of <linux/bug.h>Geert Uytterhoeven1-1/+0
No R-Car or RZ/G SYSC driver uses any of the definitions provided by <linux/bug.h>, hence there is no need to include this header file.

2019-10-01soc: renesas: r8a77970-sysc: Fix power request conflictsGeert Uytterhoeven1-0/+3
Describe the location and contents of the SYSCEXTMASK register on R-Car V3M, to prevent conflicts between internal and external power requests. Based on a patch in the BSP by Dien Pham <dien.pham.ry@renesas.com>.

2018-11-30soc: renesas: r8a77970-sysc: Correct names of A2DP/A2CN power domainsGeert Uytterhoeven1-2/+2
The R-Car Gen3 HardWare Manual Errata for Rev. 0.80 (Feb 28, 2018) renamed the A2IR2 and A2IR3 power domains on R-Car V3M to A2DP resp. A2CN. As these definitions are not yet used from DT, they can just be renamed. While at it, fix the indentation of the A3IR definition.

2018-11-30soc: renesas: r8a77970-sysc: Remove non-existent CR7 power domainGeert Uytterhoeven1-1/+0
The R-Car Gen3 HardWare Manual Errata for Rev. 0.80 (Feb 28, 2018) removed the CR7 power domain on R-Car V3M, as this SoC does not have an ARM Cortex-R7 Realtime Core. As this definition was never used from DT, it can just be removed.

According to the figure 9.2(b) of the R-Car Series, 3rd Generation User’s Manual: Hardware Rev. 0.80 the A2IRn and A2SCn power areas in R8A77970 have the A3IR area as a parent, thus the SYSC driver has those parents wrong...
