From: Geert Uytterhoeven <geert+renesas@xxxxxxxxxxxxxx> - 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@xxxxxxxxxxxxxx> --- Mark: Can you please ack and take this, so Simon can apply the patches that use these bindings? Thx! 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.
