[PATCH] drm/bridge: ti-sn65dsi86: Implement the pwm_chip

2020-12-08 Thread Bjorn Andersson
The SN65DSI86 provides the ability to supply a PWM signal on GPIO 4, with the primary purpose of controlling the backlight of the attached panel. Add an implementation that exposes this using the standard PWM framework, to allow e.g. pwm-backlight to expose this to the user. Special thanks to Doug
