Subject: [PATCH 1/2] ASoC: SOF: imx: drop usage of the imx8_*_clocks API
From: Laurentiu Mihalcea <laurentiu.mihalcea@....com>
Currently, the driver has to keep track of all the clocks
it uses via an array of "struct clk_bulk_data", which doesn't
scale well and is unnecessary. As such, replace the usage of
the imx8_*_clocks with "devm_clk_bulk_get_all()" and friends.
