Subject[PATCH v3 08/11] ARM: davinci - migrating to use common clock init code
Date
A clk_init function pointer is added to davinci_soc_info to allow
SoC code to specify a clock init function for the SoC. Also
cpu_clks, psc_bases and psc_bases_num are being obsoleted as part
of the migration. clk_init() is now called from davinci_timer_init()
as the davinci_common_init() is too early to call this function.
