soc: imx: imx8mp-blk-ctrl: register HSIO PLL clock as bus_power_dev child

2023-07-19T07:44:02+00:00

The blk-ctrl device is deliberately placed outside of the GPC power
domain as it needs to control the power sequencing of the blk-ctrl
domains together with the GPC domains.

Clock runtime PM works by operating on the clock parent device, which
doesn't translate into the neccessary GPC power domain action if the
clk parent is not part of the GPC power domain. Use the bus_power_device
as the parent for the clock to trigger the proper GPC domain actions on
clock runtime power management.

soc: imx: imx8m-blk-ctrl: reordering the fields

2023-03-27T01:52:41+00:00

The clang-analyzer reports:
"Excessive padding in 'struct imx8m_blk_ctrl_domain_data'
(12 padding bytes, where 4 is optimal). Optimal fields order: name,
clk_names, path_names, gpc_name, num_clks, num_paths, rst_mask, clk_mask,
mipi_phy_rst_mask, consider reordering the fields or adding explicit
padding members [clang-analyzer-optin.performance.Padding]
   struct imx8m_blk_ctrl_domain_data {"

So reordering the fields.

This particular block can have DT subnodes describing the LVDS LDB
bridge. Instead of misusing simple-bus to scan for those nodes, do
the scan within the driver.
