Subject: [PATCH v4 00/10] Add new partial clock and reset drivers for StarFive JH7110

This patch serises are base on the basic JH7110 SYSCRG/AONCRG
drivers and add new partial clock drivers and reset supports
about System-Top-Group(STG), Image-Signal-Process(ISP)
and Video-Output(VOUT) for the StarFive JH7110 RISC-V SoC. These
clocks and resets could be used by DMA, VIN and Display modules.

Patch 1 adds struct members to support STG/ISP/VOUT resets.

Patches 2 and 3 are about the System-Top-Group clock and reset
generator(STGCRG) part. The first patch adds docunmentation to
describe STG bindings, and the second patch adds clock driver to
support STG clocks and resets as auxiliary device for JH7110.

Patches 4 and 5 are about the Image-Signal-Process clock and reset
gennerator(ISPCRG) part. The first patch adds docunmentation to
describe ISP bindings, and the second patch adds clock driver to
support ISP clocks and resets as auxiliary device for JH7110.
And ISP clocks should power on and enable the SYSCRG clocks first
before registering.

Patches 6 and 7 are about the Video-Output clock and reset
generator(VOUTCRG) part. The first patch adds docunmentation to
describe VOUT bindings, and the second patch adds clock driver to
support VOUT clocks and resets as auxiliary device for JH7110.
And VOUT clocks also should power on and enable the SYSCRG clocks
first before registering.

Patch 8 adds the maintainer who take charge of the STGCRG/ISPCRG/VOUTCRG
for JH7110.
Patch 9 adds external clocks which ISP and VOUT clock driver need.
Patch 10 adds device node about STGCRG, ISPCRG and VOUTCRG to JH7110 dts.

Patches 1, 3, 5, 7 and 8 are dependent on the patchset [1] which
is about JH71x0 clock and reset driver (Accepted and will merge).
Patchdes 9 and 10 are dependent on the patchset [1] and [2] which is
about JH7110 device tree and PMU node.
This patchset should be applied after the patchset [1], [2]:
[1] https://lore.kernel.org/all/20230401111934.130844-1-hal.feng@starfivetech.com/
[2] https://lore.kernel.org/all/20230116074259.22874-4-walker.chen@starfivetech.com/

Changes since v3:
- Rebased on the lastest JH71X0 clock and reset driver of patchset[1]
  and modified the parameters of the register reset functions.
- The patch 1 combined three commits on STG/ISP/VOUT resets into one.
  And Changed the auxiliary_device_id name from
  "clk_starfive_jh71x0.reset-*" to "clk_starfive_jh7110_sys.rst-*".
- Added a maintainer in STARFIVE JH71X0 CLOCK DRIVERS.

v3: https://lore.kernel.org/all/20230314124404.117592-1-xingyu.wu@starfivetech.com/

Changes since v2: 
Patch 1:
- Dropped the modification of maintainers.
- Modified clock and reset names in the dt-bindings header files.
Patch 3:
- Added 'Emil Renner Berthing' as the author.
- Used 'default m' in Kconfig file.
- Changed the flags of 'CLK_IGNORE_UNUSED' to 0 or 'CLK_IS_CRITICAL'.
Patch 4:
- Dropped the 'reset-names' property.
- Shortened the clock and reset names in the dt-bindings header files.
Pacth 6:
- Used 'default m' in Kconfig file.
- Changed the flags of 'CLK_IGNORE_UNUSED' to 0.
- Set reset_control struct to a local variable because it just is used
  one time in probe.
Pacth 7:
- Dropped the 'reset-names' property.
Patch 9:
- Used 'default m' in Kconfig file.
- Set reset_control struct to a local variable because it just is used
  one time in probe.
Patch 10:
- Changed the order of externel clock in alphanumerical order.
Patch 11:
- Dropped the 'reset-names' property in ispcrg and voutcrg node.

v2: https://lore.kernel.org/all/20230221083323.302471-1-xingyu.wu@starfivetech.com/

Changes since v1:
- Modified the binding and dropped the indentation.
- Removed the useless header files in the drivers.
- Used an array lookup instead of a pile of conditions about parent
  clocks' name.
- Added clocks operation on driver remove.

v1: https://lore.kernel.org/all/20230120024445.244345-1-xingyu.wu@starfivetech.com/
