Currently the driver uses of_clk_hw_onecell_get() for all clocks it
manages, but this is incorrect for the audio refclk, which has 0 rather
than 1 clock cell according to its binding documentation [1]; attempting
to look up the clock when referenced like this in the Device Tree leads
to errors, as uninitialized memory is passed to of_clk_hw_onecell_get()
as the index.
The actual fix is in patch 3; patches 1 and 2 are preparation and
related cleanup. I've added a Fixes: tag to all 3 patches, as they
need to be backported together.
Matthias Schiffer (3):
clk: keystone: syscon-clk: use struct instead of array for match data
clk: keystone: syscon-clk: specify whether a parent is required in
match data
clk: keystone: syscon-clk: use of_clk_hw_simple_get() for audio refclk
