From: Matthias Brugger Date: Mon, 22 May 2017 09:40:19 +0000 (+0200) Subject: dt-bindings: i2c-mt6577: Rename file to reflect bindings X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8491899466eccc8957441b96bd55c7b6efd2fb3b;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git dt-bindings: i2c-mt6577: Rename file to reflect bindings The i2c-mt6577.txt actually holds the bindings for all mediatek supported i2c controller. Change the name to i2c.mtk.txt to reflect that.
