Hi guys , I need a help
<
caiortp>
I need to set an GPIO in the devicetree to enable my lcd display
<
caiortp>
the lcd enable is connected to the GPIO03_IO11 (in device tree gpio = 75)
<
caiortp>
*(in the linux is the gpio = 75)
<
caiortp>
I'm trying to add gpios = <&gpio3 11 1>;
<
caiortp>
but the pin doesn't go to '1' at the startup
<
vpeter>
caiortp: Did you define this gpio in pinctrl section?
<
caiortp>
pinctrl_reset_lcd: reset-lcd {
<
caiortp>
fsl,pins = <
<
caiortp>
MX6QDL_PAD_EIM_DA11__GPIO3_IO11 PAD_CTRL_HYS_PD /* SODIMM 116 */
<
caiortp>
it's inside of
<
caiortp>
&iomuxc {
<
caiortp>
* Mux all pins which are unused to be GPIOs
<
caiortp>
* so they are ready for export to user space
<
caiortp>
pinctrl-names = "default";
<
caiortp>
pinctrl-0 = <
<
caiortp>
&pinctrl_gpio_2
<
caiortp>
&pinctrl_usbh_oc_1
<
caiortp>
&pinctrl_usbc_id_1
<
caiortp>
&pinctrl_usbc_det_1
<
caiortp>
&pinctrl_batery_mode
<
caiortp>
&pinctrl_reset_lcd
<
caiortp>
&pinctrl_5v_fault
<
caiortp>
&pinctrl_codec_int
<
caiortp>
pinctrl_reset_lcd: reset-lcd {
<
caiortp>
fsl,pins = <
<
caiortp>
MX6QDL_PAD_EIM_DA11__GPIO3_IO11 PAD_CTRL_HYS_PD /* SODIMM 116 */
<
vpeter>
What is the value of PAD_CTRL_HYS_PD ?
<
caiortp>
opss sorry, this a macro
<
caiortp>
#define PAD_CTRL_HYS_PD 0x130b0 /*(PAD_CTL_HYS | PAD_CTL_PUE | PAD_CTL_PKE | PAD_CTL_SPEED_MED | PAD_CTL_DSE_40ohm)*/
<
caiortp>
I try to add in the lcd
<
caiortp>
pinctrl-0 = <&pinctrl_ipu1_1>;
<
caiortp>
status = "okay";
<
caiortp>
gpios = <&gpio3 11 1>;
