Depending on your tree-schedule for the merge-window, you could also pick up all 4 with my: Acked-by: Heiko Stuebner <heiko@sntech.de> Heiko

Current dts files with 'pwm' nodes are manually verified. In order to automate this process pwm-rockchip.txt has to be converted to yaml. Signed-off-by: Johan Jonker <jbx6244@gmail.com> --- For some SoC nodes this patch serie generates notifications for undocumented "interrupts" properties shared between PWM channels till there is consensus of what to do with it or someone makes a solution for the whole PWM block.
