These cores now have an open-source fixed-configuration edition, which enables everyone to explore with them. The first patch adds an compatible string set for T-Head CLINT, which is incompatible with SiFive ones by not having a mtime register. The Linux CLINT driver, which is only used in M mode now, does not support it at all -- having a DT binding is for OpenSBI. The second and third patches are for OpenC906, the open source edition of C906. They try to add some DT binding strings for it. By the way, as we discussed in the BoufalloLab series, C906/C910 do not have so many customizable options for PLIC/CLINT, so maybe we should not add additional per-SoC-system compatible strings and allow only "thead,c900-*".
