Our partner have a question about i.MX6SDL GPIO.
Please see chapter 29.5.2 in IMX6SDLRM Rev.1.
It says "If GDIR[n] is cleared and IOMUXC input mode is not GPIO, then reading DR[n] always returns zero".
With same condition (GDIR[n] is cleared and IOMUXC input mode is not GPIO), how about the value of GPIOx_PSR register?
Does is return zero same as GPIOxDR register?
