Subject: ARM: OMAP2+: gpmc: remove cs# in sync clk div calc
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=1b47ca1a127925acd73381edb8d1d462014bff1f;p=openwrt%2Fstaging%2Fblogic.git

ARM: OMAP2+: gpmc: remove cs# in sync clk div calc

Divider value for a certain sync clk is determined solely
based on gpmc fclk. CS# does not have any role here, thus
remove presence of CS# in clock divider calculation API.
