From 0b32bc4831694c0b750811589543f540a2385b40 Mon Sep 17 00:00:00 2001 From: Detlev Casanova Date: Thu, 8 Dec 2022 13:15:52 -0500 Subject: [PATCH] imx6q-sabrelite: Re-add mmc aliases In commit d0399a46e7cda63c07e3eb8558bef84cfb068028, the device tree was synchronized from linux and the aliases were dropped. They need to be kept so that the mmc cards are in the right order. Without the aliases, u-boot reports: MMC: FSL_SDHC: 2, FSL_SDHC: 3 With the aliases, u-boot reports: MMC: FSL_SDHC: 0, FSL_SDHC: 1 The upstream linux device tree does not contain the same aliases than u-boot (It keeps the devices order with /dev/mmcblk2 and /dev/mmcblk3). Because this board has been using different aliases in u-boot and linux, a imx6q-sabrelite-u-boot.dtsi file is added to be automatically included in imx6q-sabrelite.dts. This way, linux and u-boot each keep their own aliases and there is no breakage on current installations. This should never be done for new boards as we want to keep linux and u-boot with the same aliases as much as possible. This patch is only necessary to avoid breaking existing setups.
