hi, ALL
i encountered a problem for backlight.
the Backlight Brightness pin is pwm3 that correspond to SD4_DAT1 pad on my customer board.
i configured SD4_DAT1 pad to MX6Q_PAD_SD4_DAT1__PWM3_PWMO。
the platform_pwm_backlight_data is like this:
------------------------------------------------------------------------------------------------
static struct platform_pwm_backlight_data mx6_pwm_backlight_data = {
.pwm_id = 2,
.max_brightness = 248,
.dft_brightness = 128,
.pwm_period_ns = 50000,
};
-------------------------------------------------------------------------------------
and add the following code in boad init.
imx6q_add_mxc_pwm(2);
imx6q_add_mxc_pwm_backlight(2, &mx6_pwm_backlight_data);
but when i operated the Brightness in android setting, it seems not work.
Do anyone know what's missing or what's wrong?
