Subject: [PATCH v2 0/8] clk: meson: ee: use the new parent description method

Meson SoCs clock controllers use the string comparison method to describe
parent relation between the clocks, which is not optimized.

Its also use bypass clock made from device-tree clock to provide an input
clock which can be access through global name, but it still not optimal.

A recent patch [0] allows parents to be directly specified with
device-tree clock name or without string names from localy declared clocks.

This patchset replaces clock string names by clock pointers (as possible),
removes bypass clocks and uses directly device-tree clock names in parent
assignment.

Tested on GXL, GXBB, Meson8b, AXG SoCs by comparing the clock summary
(orphan too) before and after migration.

[0] commit fc0c209c147f ("clk: Allow parents to be specified without string names")

Change since v1:
- Improve comments in gxbb, g12a and meson8b files

Alexandre Mergnat (8):
  clk: meson: g12a: move clock declaration to dependency order
  clk: meson: g12a: migrate to the new parent description method
  clk: meson: gxbb: migrate to the new parent description method
  clk: meson: axg: migrate to the new parent description method
  clk: meson: meson8b: migrate to the new parent description method
  clk: meson: clk-regmap: migrate to new parent description method
  clk: meson: remove ee input bypass clocks
  clk: meson: remove clk input helper
