Subject: [PATCH] ARM: dts: rockchip: set FIFO size for SDMMC, SDIO and EMMC
Date: Fri, 28 Nov 2014 11:24:14 +0100
Message-ID: <1417170254-13615-1-git-send-email-julien.chauveau@neo-technologies.fr> (raw)

The SDMMC, SDIO and EMMC controllers use an external FIFO whose size is 256x32bit.
This patch set the corresponding fifo-depth properties for both RK3066 and RK3188.
