This patch series depends on the Initial device tree support for StarFive JH8100 SoC patch series which can be found at [1]. As it is recommended to refrain from merging fundamental patches like Device Tree, Clock & Reset, and PINCTRL tested on FPGA/Emulator, into the RISC-V Mainline, this patch series has been renamed to "RFC" patches. Yet, thanks to the reviewers who have reviewed the patches at [2]. The changes are captured below. StarFive JH8100 shares a similar clock and reset design with JH7110. To facilitate the reuse of the file and its functionalities, files containing the 'jh71x0' naming convention are renamed to use the 'common' wording. Internal functions that contain the 'jh71x0' naming convention are renamed to use 'starfive.' This is accomplished through patches 1, 2, 3, and 4. Patch 5 adds documentation to describe System (SYSCRG) Clock & Reset binding. Patch 6 adds SYSCRG clock driver. patch 7 adds documentation to describe North-West (NWCRG) Clock & Reset binding. Patch 8 adds NWCRG clock driver. patch 9 adds documentation to describe North-East (NECRG) Clock & Reset binding. Patch 10 adds NECRG clock driver. patch 11 adds documentation to describe South-West (SWCRG) Clock & Reset binding. Patch 12 adds SWCRG clock driver. patch 13 adds documentation to describe Always-On (AON) Clock & Reset binding. Patch 14 adds AON clock driver. Patch 15 adds support for the auxiliary reset driver. Patch 16 adds clocks and reset nodes to the JH8100 device tree. Changes since [2]: - Renamed the patch series to "RFC" patches. - Added the "Reviewed-by" tag from Emil for patches 1, 2 3 & 4. - Removed clk_ prefixes. - Used 4 spaces for example indentation in dt-binding documentation. - Used the same license in dt-binding. - Moved number of clocks from binding to source file. - Moved number of resets from binding ro source file. - Removed the subfolder for new clock files. - Followed the JH71xx files naming convention. - Followed the JH71xx clock naming conventions. - Followed the JH71xx resets naming conventions. - Moved the PLL fixed clock from the source file to Device Tree. - Dropped clk.dtsi and moved the clocks node to SoC.dtsi.
