Subject: [PATCH 1/3] ARM: dts: keystone-k2g-evm: Add "vqmmc-supply" property for mmc0/mmc1
Date: Wed, 25 Apr 2018 18:57:44 +0530	[thread overview]
Message-ID: <20180425132746.13911-2-kishon@ti.com> (raw)
In-Reply-To: <20180425132746.13911-1-kishon@ti.com>

Add "vqmmc-supply" property for mmc0/mmc1 to indicate the supply connected
to the IO lines. Also add dt node for ldo1 regulator required for mmc1
vqmmc-supply.
