Merge branch 'riscv-jh7110_initial_dts' into riscv-dt-for-next
Merge Hal's series adding support for the new StarFive JH7110 SoC. There's a few bindings here for core components that were not picked up by the various maintainers for the subsystems (previously Palmer would pick these up via the RISC-V tree) & the first two commits in the branch are shared with the clk tree, since the dts depends on defines in the dt-binding headers. This is based on -rc2, as the board does not actually boot on -rc1 due to the bug Linus introduced. Signed-off-by: Conor Dooley <conor.dooley@microchip.com>
