Re: [U-Boot] [PATCH v4 08/13] dm: clk: Define clk_get_parent_rate() for clk operations

This commit adds the clk_get_parent_rate() function, which is responsible for getting the rate of parent clock. Unfortunately, u-boot's DM support for getting parent is different (the parent relationship is in udevice) than the one in common clock framework (CCF) in Linux.

To alleviate this problem - the clk_get_parent_rate() function has been introduced to clk-uclass.c.

Changes in v4: None Changes in v3:

• The rate information is now cached into struct clk field
• The clk_get_parent() is used to get pointer to the parent struct clk

This also needs a test.
