Our products want to set some pins to GPIO, and control these.
When I check the docs and source code, the same PIN had a difference GPIO number of u-boot and kernel.
Example, When I want to set H3 to GPIO.
Base of u-boot source code H3 GPIO number is 59.
#define TEGRA_GPIO(bank, offset)
((TEGRA_GPIO_BANK_ID_##bank * 8) + offset)
#define TEGRA_GPIO_BANK_ID_H 7
TEGRA_GPIO(H, 3) ===> 7*8+3 = 59
But when I find this pin number on Kernel, I reference “Jetson_TX1_Generic_Customer_Pinmux_Customer_Release.xlsm”.
I find the H3 is “GPIO3_PE.06”.
Base this name and trace kernel source code, I find the H3 GPIO number is 38.
#define TEGRA_GPIO_PE6 38
So, the same pin had a difference GPIO number is correct?
