Thanks, Chen --- 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 - 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 . 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.
