From: Tero Kristo Date: Fri, 20 Feb 2015 08:08:52 +0000 (+0200) Subject: ARM: OMAP4+: control: remove support for legacy pad read/write X-Git-Tag: v4.1-rc1~45^2~3^2^2~3 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=efde234674d9db08b762d9faef4dbbaa2eba3a2e;p=karo-tx-linux.git ARM: OMAP4+: control: remove support for legacy pad read/write omap4_ctrl_pad_readl/writel are no longer used by anybody, so remove these. Syscon / pinctrl should be used to access the padconf area instead.
