Subject: [PATCH v3 05/11] clk: Provide struct clk for fixed rate clock (clk_fixed_rate.c)
Up till now the fixed rate clock ('osc') has been added to UCLASS_CLK without declaring struct clk. As a result it was only accessible by iterating the udevice's uclass list.
This is a problem for clock code, which operates on pointers to struct clk (like clk_get_rate()), not udevices.
After this change struct clk is accessible from udevice and udevice from struct clk.
