From: Geert Uytterhoeven <geert+renesas@linux-m68k.org>
- Add future-proof "renesas,hspi-<soctype>" compatible values, - Add missing "interrupt-parent", "#address-cells", and "#size-cells" properties, - Add reference to pinctrl documentation, - Add example bindings.
Signed-off-by: Geert Uytterhoeven <geert+renesas@linux-m68k.org> --- v3: - Split in two patches: bindings and dtsi updates v2: - Add Tested-by - List full example compatible properties with soctypes instead of just the soctypes, so checkpatch can validate DTSes.
