Subject: [PATCH 1/3] ARM: imx: vining2000: Clean up uSDHC4 setup
Date: Wed, 15 Jan 2020 11:27:30 +0100 [thread overview]
Message-ID: <20200115102732.167211-1-marex@denx.de> (raw)
Simplify the uSDHC4 eMMC controller setup. This is the only eMMC
present on the system and only controller that is used, so drop
the extra logic.
