Subject[PATCH v1 0/2] mmc: sdhci-of-aspeed: Support toggling SD bus signal
Date
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
