Subject: [PATCH] arm64: dts: renesas: disable SD functions for plain eMMC
Date: Tue, 19 Jan 2021 14:33:22 +0100	[thread overview]
Message-ID: <20210119133322.87289-1-wsa+renesas@sang-engineering.com> (raw)

Some SDHI instances are solely used for eMMC. Disable SD and SDIO
for faster initialization.

I recall that ARM64 maintainers prefer such changes in one block and not
individual patches. If that's not true, I can convert, of course.
