			Clean all #ifdef's added to OMAP2 clock code to make it COMMON clk ready, not that CONFIG_COMMON_CLK is enabled. Signed-off-by: Rajendra Nayak <rnayak@ti.com> [paul@pwsan.com: also drop CONFIG_COMMON_CLK tests around APLL recalc_rate functions] Signed-off-by: Mike Turquette <mturquette@ti.com> [paul@pwsan.com: remove some ifdefs in mach-omap2/io.c] Signed-off-by: Paul Walmsley <paul@pwsan.com>
