[PATCH v5 0/8] arm: Base support for Renesas RZN1D-DB Board

From: Michel Pollet
Date: Tue Apr 17 2018 - 07:09:25 EST

This series adds the plain basic support for booting a bare
kernel on the RZ/N1D-DB Board. It's been trimmed to the strict
minimum as a 'base', further patches that will add the
rest of the support, pinctrl, clock architecture and quite
a few others.

Thanks for the comments on the previous versions!

+ Given the problems I have with getting in some structure around the
sysctrl block, I've removed the MFD, I've now attached a simple reboot
driver on it's own pair of registers.
+ Rebased on next-20180417
+ Fixes for suggestions by Simon Horman
+ Fixes for suggestions by Jacopo Mondi
+ Fixes for suggestions by Geert Uytterhoeven
+ Renamed the r9a06g0xx.dtsi file, given up on trying to get a family
common file in, so dropped potential RZ/N1S support and now only
focus on RZ/N1D for this patchset.
+ Added 'always-on' to the architected timer node, because it is.
+ Added ARCH_R9A06G032, to match others patterns like RCAR
+ Sorted the .dts files, added empty lines as required.
+ Fixed patch prefixes to match git-log for bindings&dts
+ Merged board .dts & Makefile changes together
+ Rebased on next-20180410
+ Fixes for suggestions by Geert Uytterhoeven
+ Removed SoC Specific renesas,r9a06g032-xxx, as it's not needed for now.
+ Kept renesas,rzn1 as a family/generic for this family.
+ Fixed a couple of the commit messages.
+ Added Geert's Reviewed-By where appropriate.
+ Fixes for suggestions by Simon Horman
+ Fixes for suggestions by Rob Herring
+ Fixes for suggestions by Geert Uytterhoeven
+ Removed the mach file
+ Added a MFD base for the sysctrl block
+ Added a regmap based sub driver for the reboot handler
+ Renamed the files to match shmobile conventions
+ Adapted the compatible= strings to reflect 'family' vs 'part'
+ Removed the sysctrl.h file entirelly.
+ Fixed every warnings from the DTC compiler on W=12 mode.
+ Split the device-tree patches from the code.
