[PATCH] clk: imx: imx8: Add .name for "acm_aud_clk0_sel" and "acm_aud_clk1_sel"

[PATCH] clk: imx: imx8: Add .name for "acm_aud_clk0_sel" and "acm_aud_clk1_sel"

[Shengjiu Wang]

"acm_aud_clk0_sel" and "acm_aud_clk1_sel" are registered by this ACM
driver, but they are the parent clocks for other clocks, in order to
use assigned-clock-parents in device tree, they need to have the
global name.

This doesn't make any sense. Why are we adding fallback names?  Is
"acm_aud_clk0_sel" not part of the DT binding for this clk controller?

It is not part of DT binding for this clk controller.  it is registered by this
clk controller itself.  As it is a parent clock, so my understanding
is that we need to add a fallback name,  or change "fw_name" to "name",
please correct me if I am wrong.

If it's registered by this clk controller itself then it should be a
clk_hw pointer and not use any string name.
