[PATCH 0/3] clk: meson: gxbb-aoclk: Add CEC 32k clock
From: Neil Armstrong
Date: Thu Jul 06 2017 - 06:25:40 EST
In order to support the standalone CEC Controller on the Amlogic SoCs,
a specific CEC 32K clock must be handled in the AO domain.
The CEC 32K AO Clock is a dual divider with dual counter to provide a more
precise 32768Hz clock for the CEC subsystem from the external xtal.
The AO clocks management registers are spread among the AO register space,
so this patch also adds management of these registers mappings then uses them
for the CEC 32K AO clock management.
This patchset :
- updates the bindings accordingly
- adds the CEC 32k clock
- adds the clock binding entry
The DT Update will be sent in another patchset.
