From mboxrd@z Thu Jan 1 00:00:00 1970 From: nicolas.ferre@atmel.com (Nicolas Ferre) Date: Tue, 19 May 2015 11:07:16 +0200 Subject: [PATCH 1/4] ARM: at91/dt: sama5d3 xplained: fill in mmc1 and set it to disabled In-Reply-To: <1430140753-19998-1-git-send-email-ludovic.desroches@atmel.com> References: <1430140753-19998-1-git-send-email-ludovic.desroches@atmel.com> Message-ID: <555AFD44.7040007@atmel.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Le 27/04/2015 15:19, Ludovic Desroches a ?crit : > From: Ben Dooks > > The mmc1 channel is not populated on the SAM5D3 Xplained board, however > it is enabled and therefore the driver is attaching to it. > > The node configuration for mmc1 is missing, so add an mmc1 node in the > device tree and set its status to disabled. Also add the vmmc and the > necessary slot configuration if this node were enabled to avoid the following > warnings from the driver: > > atmel_mci f8000000.mmc: No vmmc regulator found > atmel_mci f8000000.mmc: No vqmmc regulator found > > Signed-off-by: Ben Dooks > Signed-off-by: Ludovic Desroches Acked-by: Nicolas Ferre and queued on at91-4.2-dt branch. I also sent the update of the at91 defconfigs. We may need to have a kind of synchronization between them... but a loose one should be okay...
