Subject: [PATCH 2/2] ARM: dts: imx7d-pico: Pass 'no-1-8-v' property to the eMMC
Date: Tue, 23 May 2017 12:16:09 -0300	[thread overview]
Message-ID: <1495552569-18567-2-git-send-email-fabio.estevam@nxp.com> (raw)
In-Reply-To: <1495552569-18567-1-git-send-email-fabio.estevam@nxp.com>

Currently the following eMMC error is seen:

mmc1: mmc_select_hs200 failed, error -74

On imx7d-pico the eMMC VCCQ is fixed at 3.15V, so pass the 'no-1-8-v'
property to properly describe that 1.8V operation is not possible.
