From mboxrd@z Thu Jan 1 00:00:00 1970 From: ben.dooks@codethink.co.uk (Ben Dooks) Date: Thu, 26 Mar 2015 17:38:25 +0000 Subject: [PATCH 3/3] ARM: at91/dt: sama5d3 add gpio regulator for vmmc0 In-Reply-To: <1427391505-29129-1-git-send-email-ben.dooks@codethink.co.uk> References: <1427391505-29129-1-git-send-email-ben.dooks@codethink.co.uk> Message-ID: <1427391505-29129-4-git-send-email-ben.dooks@codethink.co.uk> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Add gpio regulator for vmmc0 and attach the vmmc for it to the mmc0 node on the SAM5D3 Xplained board. This will remove the following warning from the kernel: atmel_mci f0000000.mmc: No vmmc regulator found Note, atmel_defconfig will need gpio regulator support enabled if this is to be used properly.
