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.

soc: imx: imx8m-blk-ctrl: Scan subnodes and bind drivers to them

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.

Pull ARM SoC driver updates from Arnd Bergmann:
 "As usual, there are lots of minor driver changes across SoC platforms
  from NXP, Amlogic, AMD Zynq, Mediatek, Qualcomm, Apple and Samsung.
  These usually add support for additional chip variations in existing
  drivers, but also add features or bugfixes.

  The SCMI firmware subsystem gains a unified raw userspace interface
  through debugfs, which can be used for validation purposes.

  Newly added drivers include:

   - New power management drivers for StarFive JH7110, Allwinner D1 and
     Renesas RZ/V2M

   - A driver for Qualcomm battery and power supply status

   - A SoC device driver for identifying Nuvoton WPCM450 chips

   - A regulator coupler driver for Mediatek MT81xxv"
