Camera reset pin is H8 or R5?

I see the reset-gpio is TEGRA_MAIN_GPIO(R, 5) in device tree:

reset-gpios = <&tegra_main_gpio TEGRA_MAIN_GPIO(R, 5) GPIO_ACTIVE_LOW>;

In sensor driver programming guide, I see the camera reset pin is R5 :

But I see the GPIO2_CAM0_RST# pin is H8 in the JetsonTX2_TX2i_OEM_Product_Design_Guide_20180618.pdf :

So how to mapping camera reset pin to TX2 module? is H8? is R5?

Please refer to pinmux sheet in DLC. TEGRA_MAIN_GPIO(R, 5) means GPIO3_PR.05 not pin R5 as listed in sheet which is mapped to pin H8.

OK, I got it and thank you.
May I to know which document I can get more about GPIO pinmux relation information?
