i.MX7ULP EVK board has MIPI-DSI display, its backlight is supplied by TPM PWM module, this patch set enables i.MX7ULP TPM PWM driver support and also add backlight support for MIPI-DSI display.
Changes since V9: - update compatible string in DT binding, pwm driver and DTS file; - update PWM driver logic of changing period and duty, put them in 1 function; - update node name to be "pwm", and label name to be "tpm4".
Anson Huang (5): dt-bindings: pwm: Add i.MX TPM PWM binding pwm: Add i.MX TPM PWM driver support ARM: imx_v6_v7_defconfig: Add TPM PWM support by default ARM: dts: imx7ulp: Add tpm pwm support ARM: dts: imx7ulp-evk: Add backlight support
