From 5f65328df3f5cd25af741638153929d3c7ad4d8a Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Sun, 4 Nov 2018 21:37:07 +0100 Subject: arm64: dts: renesas: Switch eMMC bus to 1V8 on Salvator-X and ULCB The eMMC card has two supplies, VCC and VCCQ. The VCC supplies the NAND array and the VCCQ supplies the bus. On Salvator-X and ULCB, the VCC is connected to 3.3V rail, while the VCCQ is connected to 1.8V rail. Adjust the pinmux to match the bus, which is always operating in 1.8V mode. While at it, deduplicate the pinmux entries, which are now the same for both default and UHS modes. We still need the two pinctrl entries to match the bindings though.
