Geert Uytterhoeven 3b1600c515 soc: renesas: rcar-sysc: Remove unneeded inclusion of <linux/bug.h> 
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.

Geert Uytterhoeven 8c32c5ff87 soc: renesas: r8a774c0-sysc: Fix power request conflicts 
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>.

Biju Das a64597227d soc: renesas: r8a774c0-sysc: Fix initialization order of 3DG-{A,B} 
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.
