[PATCH v3 00/11] Add new partial clock and reset drivers for StarFive JH7110

[Xingyu Wu]

This patch serises are to 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.

Patches 1 to 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 support about STG resets. The last patch adds
clock driver to support STG clocks for JH7110.

Patches 4 to 6 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 support about ISP resets. The last patch adds
clock driver to support ISP clocks for JH7110.

Patches 7 to 9 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 support about VOUT resets. The last patch adds
clock driver to support VOUT clocks for JH7110.

Patch 10 adds external clocks which ISP and VOUT clock driver need.
Patch 11 adds device node about STGCRG, ISPCRG and VOUTCRG to JH7110 dts.

Patches 2, 3, 5, 6, 8 and 9 are dependent on the patchset [1] which
is about JH71x0 clock and reset driver.
Patchdes 10 and 11 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]:

[2] https://lore.kernel.org/all/20230116074259.22874-4-walker.chen@xxxxxxxxxxxxxxxx/

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@xxxxxxxxxxxxxxxx/

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@xxxxxxxxxxxxxxxx/
