Subject: arm64: dts: amlogic: t7: Add PWM controller nodes
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=97f08cef69118bff9b7901bb1c804e7e326b31bf;p=thirdparty%2Fkernel%2Flinux.git

arm64: dts: amlogic: t7: Add PWM controller nodes

Add device tree nodes for the seven PWM controllers available
on the Amlogic T7 SoC, using amlogic,meson-s4-pwm as fallback compatible.
All nodes are disabled by default and should be
enabled in the board-specific DTS file.
