Commit 941432d00768 ("arm64: dts: allwinner: Drop non-removable from SoPine/LTS SD card") enabled the card detect GPIO for the SOPine module, along the way with the Pine64-LTS, which share the same base .dtsi. However while both boards indeed have a working CD GPIO on PF6, the polarity is different: the SOPine modules uses a "push-pull" socket, which has an active-high switch, while the Pine64-LTS use the more traditional push-push socket and the common active-low switch. Fix the polarity in the sopine.dtsi, and overwrite it in the LTS board .dts, to make the SD card work again on systems using SOPine modules. Fixes: 941432d00768 ("arm64: dts: allwinner: Drop non-removable from SoPine/LTS SD card") Reported-by: Ashley <contact@victorianfox.com> Signed-off-by: Andre Przywara <andre.przywara@arm.com> --- Hi, sorry, that slipped through my testing. I verified that the CD switch worked, but didn't actually boot Linux on the SOPine baseboard. Thanks to Ashley for the heads up!
