[PATCH 1/3] ARM: renesas: condor: switch eMMC bus to 1V8
From: Hai Pham hai.pham.ud@renesas.com
The eMMC card has two supplies, VCC and VCCQ. The VCC supplies the NAND array and the VCCQ supplies the bus. On Condor, 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.
Based on Linux commit 69efe4bbeda50745 ("arm64: dts: renesas: condor: Switch eMMC bus to 1V8") from Wolfram Sang

This enables MMC support, which is available on Condor board, by default.
