Hello,
This series implements support for toggling SD bus signal voltage by GPIO pin.
This series has been tested on AST2600-A2 EVB with APLL and 200MHz HCLK clock source with sdr104, sdr50, sdr25, sdr12 and high speed mode. This series were also be tested on AST2600-A1 EVB and AST2500 EVB that don't have the design of signal voltage toggling by GPIO.
Please help to review.
Regards, Steven
