Subject: [PATCH v8 0/5] riscv: sophgo: add clock support for sg2042

From: Chen Wang <unicorn_wang@...look.com>

This series adds clock controller support for sophgo sg2042.

Thanks,
Chen

Changes in v8:
  The patch series is based on v6.7. You can simply review or test the
  patches at the link [9].
  
  In this version, the main change is to split one clock provider into two.
  Strictly follow the hardware instructions, in the memoymap, the control
  registers of some clocks are defined in the SYS_CTRL segment, and the
  control registers of other clocks are defined in the CLOCK segment.
  Therefore, the new design defines two clock controllers, one as a child
  node of the system control and the other as an independent clock controller
  node.

  This modification involves a major modification to the binding files, so
  the reviewed-by tags has been deleted.

Changes in v7:
  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@...el.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@...el.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.

Changes in v1:
  The patch series is based on v6.7-rc1. You can simply review or test the
  patches at the link [1].
