Using GPT1 in Linux on iMX8MPlus

[alexeyfirago]

Hi all,

We have a custom board based on iMX8MPlus. We want to use GPT1 to capture a signal on SAI3_TXC. We are using kernel revision imx-5.4.47_2.2.0 and revision imx-atf imx_5.4.47_2.2.0.

Is it possible to use GPT1 in Linux? Will adding a DTS node for GPT be enough? Or we also should patch imx8mp_bl31_setup.c in imx-atf?

Thanks!
