Changes since v2:
- Rebased on tag v6.1.
- Added "JH71X0" to the StarFive driver headers in MAINTAINERS.
- Removed Co-developed-by tag of Hal in patch 1 and patch 4.
- Changed the commit author from Hal to Emil in patch 2 and patch 5.
  Removed Co-developed-by tag of Emil in patch 2 and patch 5. (by Emil)
- Improved the coding style of patch 11, 12 and 13.
- Dropped patch 14. (by Emil)
Patch 4:
- Passed the "owner" member of reset_controller_dev structure
  directly in reset_starfive_jh7100_register(). (by Emil)
- Added MAINTAINERS changes.
Patch 7:
- Split patch 7 into sys part and aon part. Merged them into patch 9 and
  patch 10 respectively. (by Krzysztof)
- Renamed include/dt-bindings/clock/starfive-jh7110.h to
  include/dt-bindings/clock/starfive,jh7110-crg.h. (by Krzysztof)
- Synchronized the definitions with the latest changes from Emil.
Patch 8:
- Split patch 8 into sys part and aon part. Merged them into patch 9 and
  patch 10 respectively. (by Krzysztof)
- Renamed include/dt-bindings/reset/starfive-jh7110.h to
  include/dt-bindings/reset/starfive,jh7110-crg.h. (by Krzysztof)
- Fixed the date of Copyright. (by Emil)
- Dropped weird indentations. (by Krzysztof)
- Synchronized the definitions with the latest changes from Emil.
Patch 9:
- Improved the description of clocks. (by Emil and Krzysztof)
- Added MAINTAINERS changes.
Patch 10:
- Improved the description of clocks. (by Emil and Krzysztof)
- Changed the clock-name "clk_rtc" to "rtc_osc" and  "apb_bus_func" to
  "apb_bus".
Patch 11:
- Removed the flags of trace/debug clocks and set the flags of core clocks
  as CLK_IS_CRITICAL. (by Emil)
- Deleted the extra 1-1 clocks and synchronized the clock tree with the
  latest changes from Emil. (by Emil)
- Selected RESET_STARFIVE_JH7110 in Kconfig option CLK_STARFIVE_JH7110_SYS.
Patch 12:
- Changed the macro JH7110_AONCLK_RTC to JH7110_AONCLK_RTC_OSC and
  JH7110_AONCLK_APB_BUS_FUNC to JH7110_AONCLK_APB_BUS.
- Synchronized the clock tree with the latest changes from Emil.
- Set the MODULE_LICENSE as "GPL" according to commit bf7fbeeae6db.
Patch 13:
- Removed the "asserted" member in reset_info structure and always pass
  NULL when calling reset_starfive_jh71x0_register(). (by Emil)

  v2: https://lore.kernel.org/all/20221118010627.70576-1-hal.feng@starfivetech.com/

Changes since v1:
- Rebased on tag v6.1-rc5.
- Rewrote the clock and reset drivers using auxiliary bus framework, so
  patch 8, 9, 15 were dropped and all patches changed a lot. (by Stephen)
- Split Patch 14 into two patches. One is for factoring out the common
  JH71X0 code, the another one is for renaming. (by Stephen)
- Created a subdirectory for StarFive reset drivers.
- Factored out common JH71X0 reset code.
- Renamed the common clock and reset code from "*starfive*" or
  "*STARFIVE*" to "*jh71x0*" or "*JH71X0*".
- Combined JH7110 system and always-on clock DT binding headers in one
  file named "include/dt-bindings/clock/starfive-jh7110.h".
- Renamed clock definitions "JH7110_SYSCLK_PCLK2_MUX_FUNC_PCLK" and
  "JH7110_SYSCLK_U2_PCLK_MUX_PCLK" to "JH7110_SYSCLK_PCLK2_MUX_FUNC" and
  "JH7110_SYSCLK_PCLK2_MUX".
- Rewrote the DT bindings of clock and reset for using auxiliary bus.
- Registered an auxiliary device for reset controller in clock drivers.
- Changed clock names "CODAJ*" and "WAVE*" to "codaj*" and "wave*".
  Changed clock names "u2_pclk_mux_func_pclk" and "u2_pclk_mux_pclk" to
  "pclk2_mux_func" and "pclk2_mux".
- Changed the flags of clock apb0 and noc_bus_isp_axi to CLK_IS_CRITICAL
  as suggested by StarFive SDK group.
- Registered clock gmac0_gtxc as a gate clock instead of a div clock
  as suggested by StarFive SDK group.
- Changed the frequency of clock pll2_out to 1188MHz as suggested by
  StarFive SDK group.
- Fixed the bug that the clock JH7110_AONCLK_GMAC0_GTXCLK was not handled
  in JH7110 always-on clock driver.
- Registered the reset driver as an auxiliary driver.
- Reworded the commit messages.
