Subject: ARM: OMAP2+: clock: introduce ti_clk_features flags
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8111e01045c1b3ac6b5d3c2ee3b8dc562efdf3ae;p=linux-beck.git

ARM: OMAP2+: clock: introduce ti_clk_features flags

This shall be used to replace the cpu type checks around the clock code.
Actual bit values will be introduced in patches later.
