V9:
 Per Shawn's comments in patch 3:
  License still keep GPL per ./Documentation/process/license-rules.rst
  Sort header in patch 3
  Update of_device_id variable to be driver specific

 Per Shawn's comments in patch 4:
   Drop: Reported-by: kernel test robot
   imx93-blk-ctrl.o in a separate line in Makefile
   Move reg_access_table from imx93_blk_ctrl_domain_data to imx93_blk_ctrl_data
   Drop 'const struct imx93_blk_ctrl_domain_data *bus', and add related fields in imx93_blk_ctrl_data 
   Use genpd_xlate_onecell
   Drop extra uneccesary domain allocation in probe
   Align indent
   License still keep GPL per ./Documentation/process/license-rules.rst

 Shawn:
  patch 5, 6 may conflict with [1], because both patchsets are based on linux-next/master.
  If this patchset goes fast, I could rebase [1].
  If [1] goes fast, I could rebase patch 5, 6 in this patchset. But if the binding or driver is
  good, I hope you could pick binding/driver first, I rebase patch 5,6 in a separate patch later.

V8:
 Fix error reported by kernel test robot

V7:
 Added R-b for dt-bindings
 Addressed Shawn's comments for patch 3, 4
 Included NoC default settings in patch in patch 4
 Use regmap access table to restrict the access to blk-ctrl register in patch 4
 Update node name in patch 5, 6

V6:
 Per Rob's comments to patch 1:
  Drop the ref to power-domain.yaml
  Describe each item of reg
 Per Randy's comment, drop duplicated support in Kconfig
 Per kernel test robot, use `void __iomem *` instead `void * __iomem`
 not default select PM_GENERIC_DOMAINS for SOC_IMX9

V5:
 Update bindings for SRC, remove the slices node
   Although there are several mix-slices, mem-slices, but actually
   they should work together, so I use one node to group a mix/mem with
   dual reg entries.
 Add SRC driver to include a driver to populate subnodes of SRC node
 Restructure SRC-PD driver, because slices node dropped.
 Drop the patch to export of_clk_bulk_get_all, which is not needed.

V4:
 Correct including fsl,imx93-power.h, not imx93-power.h in driver

V3:
  Move src yaml to power directory.
  Update slice name to slices

V2:
  yaml fix

This patchset is to support i.MX93 SRC and mediamix blk ctrl.
SRC functions as power domain provider as i.MX8M GPC.
mediamix blk ctrl is similar with i.MX8M blk ctrl, but much simplier from
software view.

Add bindings and dts node
