ARM: AM33XX: clock: add clock data in common clock format
OMAP2/3/4 clock-tree data is migrated to common-clock framework, so it is needed to do same for AM33XX device. Signed-off-by: Vaibhav Hiremath <hvaibhav@ti.com> Cc: Rajendra Nayak <rnayak@ti.com> Cc: Paul Walmsley <paul@pwsan.com> Cc: Benoit Cousson <b-cousson@ti.com> [paul@pwsan.com: replace omap2_init_clksel_parent() with omap2_clksel_find_parent_index(); modified to not use the AM33xx common clock data yet; updated patch description; reflowed the macros; updated DEFINE_STRUCT_CLK_HW_OMAP usage to include clkdm_name] Signed-off-by: Mike Turquette <mturquette@ti.com> Signed-off-by: Paul Walmsley <paul@pwsan.com>
