I’m trying to enable I2S microphone on Hikey970 now.
Currently, I’m trying to enable i2s0 channel that will be connected a microphone, However, the pin control information for i2s0 is not supported in hikey970-pinctrl.dtsi.
And I can not make it because I don’t have any technical document of the Hikey970 GPIO controlling.
Could anyone please give me some advice to make pin control information for i2s0 on Hikey970?
thanks in advance.
