[PATCH 18/22] msm: clock: Migrate to clkdev
Stephen Boyd
sboyd at codeaurora.org
Thu Dec 16 19:50:02 EST 2010
Migrating to clkdev has several advantages:
* Less code in mach-msm/clock.c
* A more robust clk_get() implementation
* clk_add_alias() support
* clk_get_sys() support
In general, this will help board authors setup clock aliases and
break the dependency on device pointers in the clock tables.
