Subject: [PATCH 0/4] clk: meson: ao: use the new parent description method
Date: Mon, 22 Jul 2019 11:50:49 +0200	[thread overview]
Message-ID: <20190722095053.14104-1-amergnat@baylibre.com> (raw)

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")

Alexandre Mergnat (4):
  clk: meson: g12a-aoclk: migrate to the new parent description method
  clk: meson: gxbb-aoclk: migrate to the new parent description method
  clk: meson: axg-aoclk: migrate to the new parent description method
  clk: meson: remove ao input bypass clocks
