Subject: [PATCH V10 0/5] Add i.MX7ULP EVK PWM backlight support

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
