sunxi: mellowflyc5: configure card detect GPIO for mmc0 in U-Boot

deece · deece · commit ffc8c8cf0bd4 · 2026-07-12T19:42:27.000+10:00
Replace 'broken-cd;' with 'cd-gpios = &lt;&amp;pio 5 6 GPIO_ACTIVE_LOW&gt;;' in
the U-Boot device tree patch for the Mellow Fly-C5.

We verified on physical hardware that the PF6 pin is wired to the card
detect switch, operating as active-low (logical high when empty, logical
low when a card is inserted).
