Both dt_binding_check and dtbs_check (for ARCH=arm) are happy, apart from errors like: arch/arm/boot/dts/bcm2711-rpi-4-b.dtb: pwm@7e20c000: #pwm-cells:0:0: 3 was expected From schema: Documentation/devicetree/bindings/pwm/pwm-bcm2835.yaml which is fixed in patch #6. So: Reviewed-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Who will pick up this patch? Is it supposed to go in via pwm or arm/broadcom? (I suggest the latter.) Best regards Uwe

My concern is only that nobody might feel responsible and think the other party will pick up. Thierry didn't pick up patches yet for the next merge window (or I missed it), so I guess it's not yet to late for going in via pwm. I suggest to let it go in via the arm/broadcom tree, to have the whole series together. Best regards Uwe
