Basic support for the Gen 3 R-Car M3-N SoC.
Based on original work from:
Takeshi Kihara <takeshi.kihara.df@xxxxxxxxxxx>
Magnus Damm <damm+renesas@xxxxxxxxxxxxx>
Signed-off-by: Jacopo Mondi <jacopo+renesas@xxxxxxxxxx>
---
v1 -> v2:
- Split r8a77965.dtsi from patch v1 [5/15]
- Replace all PD_ and CLK_ defines with numeric entries
- Move timer and pmu nodes outside of soc node and replace their
"interrupt" property with "interrupt-extended" one
- Fix license header
