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: r8a774c0-sysc: Fix power request conflictsGeert Uytterhoeven1-0/+3
Describe the location and contents of the SYSCEXTMASK register on RZ/G2E, to prevent conflicts between internal and external power requests. Based on a patch in the BSP by Dien Pham <dien.pham.ry@renesas.com>.

2019-01-07soc: renesas: r8a774c0-sysc: Fix initialization order of 3DG-{A,B}Biju Das1-19/+4
The workaround for the wrong hierarchy of the 3DG-{A,B} power domains on RZ/G2E ES1.0 corrected the parent domains. However, the 3DG-{A,B} power domains were still initialized and powered in the wrong order, causing 3DG operation to fail. Fix this by changing the order in the table at runtime, when running on an affected SoC. This work is based on the work done by Geert for R-Car E3.
