The issue is exposed by
https://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/
linux.git/commit/?h=for-next&id=936c383673b9e3007432f17140ac62de53d87db9

Since the upper patch not in Linus tree, I not add Fixed tag.

The issue is bus clk should be registered using bus composite api, not
peripheral api. Otherwise we will met failed to assigned clock parents error log.
Because peripheral critical clk has CLK_SET_PARENT_GATE and CLK_IS_CRITICAL,
you will not able to set clk parents.

We need use bus critical clk api to register the clks, so introduce
a new helper and use it.

Peng Fan (5):
  clk: imx: add imx8m_clk_hw_composite_bus_critical
  clk: imx8mq: fix noc and noc_io registration
  clk: imx8mm: fix bus critical clk registration
  clk: imx8mn: fix bus critical clk registration
  clk: imx8mp: fix bus critical clk registration
