Can you use subjects that match previous submissions done to the driver:

6e2e7c9fdae3 clk-kona-setup: Use kmalloc_array() in parent_process()
f37fccce4cc1 clk: bcm: kona: Migrate to clk_hw based registration and OF
APIs
4087a5f2e5e7 clk: bcm/kona: Do not use sizeof on pointer type
7926b3f8c626 clk: bcm/kona: Remove ccu_list
dc613840a625 clk: bcm281xx: add clock hysteresis support
a597faccc7ee clk: bcm281xx: add clock policy support
03548ec06ad3 clk: bcm281xx: define CCU clock data statically
b12151ca5cd7 clk: bcm281xx: initialize CCU structures statically
e756325206eb clk: bcm281xx: use init_data.name for clock name
e813d49d2a47 clk: bcm281xx: don't use unnamed structs or unions
1a5823c9209f clk: bcm281xx: don't disable unused peripheral clocks
1f27f15258bf clk: bcm281xx: add initial clock framework support

[media] is not appropriate here, other than that, the changes look good,
thanks.
