  The patch series is based on v6.7. You can simply review or test the
  patches at the link [8].
  - fixed initval issue.
  - fixed pll clk crash issue.
  - fixed warning reported by <lkp@intel.com>
  - code optimization as per review comments.
  - code cleanup and style improvements as per review comments and checkpatch
    with "--strict"

Changes in v6:
  The patch series is based on v6.7-rc1. You can simply review or test the
  patches at the link [7].
  - fixed some warnings/errors reported by kernel test robot <lkp@intel.com>.

Changes in v5:
  The patch series is based on v6.7-rc1. You can simply review or test the
  patches at the link [6].
  - dt-bindings: improved yaml, such as:
    - add vendor prefix for system-ctrl property for clock generator.
    - Add explanation for system-ctrl property.
  - move sophgo,sg2042-clkgen.yaml to directly under clock folder.
  - fixed bugs for driver Makefile/Kconfig
  - continue cleaning-up debug print for driver code.

Changes in v4:
  The patch series is based on v6.7-rc1. You can simply review or test the
  patches at the link [5].
  - dt-bindings: fixed a dt_binding_check error.

Changes in v3:
  The patch series is based on v6.7-rc1. You can simply review or test the
  patches at the link [3].
  - DTS: don't use syscon but define sg2042 specific system control node. More
    background info can read [4].
  - Updating minor issues in dt-bindings as per input from reviews.

Changes in v2:
  The patch series is based on v6.7-rc1. You can simply review or test the
  patches at the link [2].
  - Squashed the patch adding clock definitions with the patch adding the
    binding for the clock controller.
  - Updating dt-binding for syscon, remove oneOf for property compatible;
    define clock controller as child of syscon.
  - DTS changes: merge sg2042-clock.dtsi into sg2042.dtsi; move clock-frequency
    property of osc to board devicethree due to the oscillator is outside the
    SoC.
  - Fixed some bugs in driver code during testing, including removing warnings
    for rv32_defconfig.
  - Updated MAINTAINERS info.
