2022-06-20ARM: dts: imx6q-apalis: backlight pwm: Adapt brightness stepsMax Krummenacher1-2/+2
Adapt the brightness steps as the backlight doesn't light up for very low duty cycles. Signed-off-by: Max Krummenacher <[email protected]> Signed-off-by: Shawn Guo <[email protected]>
2022-06-20ARM: dts: imx6q-apalis: backlight pwm: Simplify inverted backlightMax Krummenacher1-5/+5
Set #pwm-cells to the default 3 to gain access to the parameter which allows inverting the PWM signal. This is useful to specify a backlight which has its highest brightness at 0. With the change to use the PWM with inverted polarity the PWM signal is inverted to how it was before this patch. This changes the meaning of the values in the brightness-levels property. I.e. the duty-cycle changes from x/255 to (255-x)/255. Keeping the brightness-levels will then have a big brightness jump from 0 to 127 duty cycle, the other 6 steps will then be barely noticeable. Change the brightness-levels to provide the same brightness-levels as before. Signed-off-by: Max Krummenacher <[email protected]> Signed-off-by: Shawn Guo <[email protected]>
2022-06-20ARM: dts: imx6q-apalis: Add support for Toradex Ixora V1.2 carrier boardsMax Krummenacher3-166/+289
The Ixora V1.2 carrier board adds SW relevant new features compared to the V1.1 version. - An I2C EEPROM is added. - The SD card slot got a switchable 3.3V supply. - Pull ups on the SD card signals are not assembled to faciliate 1.8V speed modes. - The CAN transceivers got a switchable 3.3V supply. Add a new device tree and, as the differences are so small rework the device tree for V1.1 to include the V1.2 device tree and adjust as needed. Drop adding the toradex,apalis_imx6q-ixora to the dtb compatible to adhere to the binding yaml document.

Skov's i.MX6 based boards come in different flavors which have different panels attached. For optimal contrast experience each panel type needs an individual common voltage (VCOM) to drive its TFT backplane. The latter is generated by an LCD bias supply IC controlled by a pwm as input signal.
