[PATCH v2 2/3] drivers: clk: Add support for versa3 clock driver

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add support for Renesas versa3 clock driver(5p35023).
The clock generator provides 6 output clocks.

Signed-off-by: Biju Das <biju.das.jz@xxxxxxxxxxxxxx>
---
RFC->v2:
 * Dropped header file <linux/clk.h> and removed all
   consumer api's
 * struct clk_parent_data used for assigning the parent names.
 * Replaced initpointer->const init pointer in vc3_clk_register
 * Replaced of_clk_add_hw_provider with devm_clk_add_hw_provider
 * Dropped vc3_remove() callback.
