From: Ben Dooks Date: Mon, 27 Apr 2015 13:19:12 +0000 (+0200) Subject: ARM: at91/dt: sama5d3 xplained: add fixed regulator for vmmc0 X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1b53e3416dd05dd515d90ef8e587119da57328fe;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git ARM: at91/dt: sama5d3 xplained: add fixed regulator for vmmc0 Add fixed 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 fixed regulator support enabled if this is to be used properly.
