From: Chen Wang <unicorn_wang@xxxxxxxxxxx> Milk-V Pioneer [1] is a developer motherboard based on SOPHON SG2042 [2] in a standard mATX form factor. Add minimal device tree files for the SG2042 SOC and the Milk-V Pioneer board. Now only support basic uart drivers to boot up into a basic console. Thanks, Chen --- Changes in v5: The patch series is based on v6.6-rc1. You can simply review or test the patches at the link [7]. - dts: changed plic to support external interrupt - pickup improvements from Conor, details refer to [8]. Changes in v4: The patch series is based on v6.6-rc1. You can simply review or test the patches at the link [6]. - Update bindings files for sg2042 clint as per intput from reviewers: - rename filename from sophgo,sg2042-clint-mswi/sg2042-clint-mtimer to thead,c900-aclint-mswi/thead,c900-aclint-mtimer. - rename compatible strings accordingly. - Update dts as per input from reviewers: don't use macro for cpus's isa properties; use new compatible strings for mtimer/mswi of clint. - Use only one email-address for SoB. Changes in v3 [v3]: The patch series is based on v6.6-rc1. You can simply review or test the patches at the link [5]. - add new vendor specific compatible strings to identify timer/mswi for sg2042 clint - updated maintainers info. for sophgo devicetree - remove the quirk changes for uart - updated dts, such as: - add "riscv,isa-base"/"riscv,isa-extensions" for cpus - update l2 cache node's name - remove memory and pmu nodes - fixed other issues as per input from reviewers. Changes in v2 [v2]: The patch series is based on v6.6-rc1. You can simply review or test the patches at the link [4]. - Improve format for comment of commitments as per input from last review. - Improve format of DTS as per input from last review. - Remove numa related stuff from DTS. This part is just for optimization, may add it later if really needed. Changes in v1: The patch series is based on v6.6-rc1. Due to it is not sent in thread, I have listed permlinks of the patchset [v1-0/12] ~ [v1-12/12] here for quick reference. You can simply review or test the patches at the link [3].
