This patchset adds 36bit dma address and power management
supports for mt8192-nor. Additionally, use dma_alloc_coherent()
instead of kmalloc() for internal bounce buffer for platforms
of only supporting 32bit addresses.

Changes in v4:
- Drop two patches from a list which already addressed by
  an another series and not directly related with mt8192 support
- Fix 0-day ci 'shift-count-overflow' warning
- Fix missing 'high_dma' initialization for 36bit address

Changes in v3:
- Fix a bugfix of v2 in checking spi memory operation.
- split read_dma function into two (normal/bounce)
- Support 7bytes generic spi xfer

Changes in v2:
- Add power management support
- Fix bugs in checking spi memory operation.
- use dma_alloc_coherent for allocating bounce buffer
- code cleanups

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
