Subject: [PATCH 5.4 120/340] ASoC: simple-card-utils: Fix device module clock
From: Sameer Pujar <spujar@...dia.com>
[ Upstream commit 1e30f642cf2939bbdac82ea0dd3071232670b5ab ]
If "clocks = <&xxx>" is specified from the CPU or Codec component
device node, the clock is not getting enabled. Thus audio playback
or capture fails.
Fix this by populating "simple_dai->clk" field when clocks property
is specified from device node as well. Also tidy up by re-organising
conditional statements of parsing logic.
Fixes: bb6fc620c2ed ("ASoC: simple-card-utils: add asoc_simple_card_parse_clk()")
