[v2,0/3] Add basic SPI support on TH1520

Message

Implemented basic SPI support for TH1520 SoC. There are two SPIs reserved
on the LicheePi4A, one on the SPI Flash pads that are blanked out on the
back, and one on the pins. I implemented the one connected to the pad.

It is using a fixed clock of 396MHz. The address and clock frequency was
referenced from the TH1520 System Reference Manual [1].

I have tested this on the LicheePi4A.

Changes made in v2:
- Changed from single patch file to a patchset by splitting the single
commit into dt-bindings, driver and the devicetree.

Thanks!

[1/3] dt-bindings: spi: snps,dw-apb-ssi.yaml: update compatible property
      commit: 6c387fb263363347185bd7a213ad175c174d35dc

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
