From 34439f73d92171cff478bd454cd812a5a50fbdd0 Mon Sep 17 00:00:00 2001 From: Tuomas Tynkkynen Date: Sat, 23 Dec 2017 00:30:56 +0200 Subject: [PATCH] ARM: sunxi: Remove left-over cd-inverted property from pcDuino3 Commit 8620f384098b ("dm: sunxi: Linksprite_pcDuino3: Correct polarity of MMC card detect") claims that the Pcduino3 device tree had an incorrect polarity for the card detect pin and thus changed the polarity flag of the cd-gpios from GPIO_ACTIVE_HIGH to GPIO_ACTIVE_LOW. Actually the DT was correct since according to the mmc binding, a combination of GPIO_ACTIVE_HIGH + cd-inverted results in an active-low polarity. But because the U-Boot driver lacks the code to look at the cd-inverted property (unlike the Linux driver) it interpreted the polarity of active-high. Thus, after that commit the DT is actually wrong from the binding/Linux point of view. To make both Linux and U-Boot interpret the DT in the same way, just drop the left-over cd-inverted property. I've sent a Linux patch to switch all sunxi DTs over to not using the cd-inverted property, so eventually all sunxi boards in U-Boot will be consistent in not using cd-inverted.
