Hi!
In the dts file can find the configuration below!
ov5693_a@36 {
compatible = "nvidia,ov5693";
reg = <0x36>;
devnode = "video0";
physical_w = "3.674";
physical_h = "2.738";
avdd-reg = "vana";
iovdd-reg = "vif";
clocks = <0xd 0x59 0xd 0x10d>;
clock-names = "extperiph1", "pllp_grtba";
mclk = "extperiph1";
clock-frequency = <0x16e3600>;
reset-gpios = <0x12 0x8d 0x0>;
pwdn-gpios = <0x12 0x88 0x0>;
vana-supply = <0x1d>;
My question is “pwdn-gpios = <0x12 0x88 0x0>” represent which gpio number, what’s the principle to get the number?
(By check the hardware designation, I find pwdn-gpios is connect to GPIO3_PR.01 pin (457))
