[PATCH v2 00/11] serial: 8250: split LPSS to 8250_lpss, enable DMA on Quark

Show all headers | View raw

This is combined series of two things:
- split out the Intel LPSS specific driver from 8250_pci into 8250_lpss
- enable DMA support on Intel Quark UART

The patch has been tested on few Intel SoCs / platforms.

This is targeting serial subsystem, thus it would be nice to get and Ack from Vinod first.
Moreover, the series depends on [1] that is now under review.

That's why I asked Vinod to create immutable tag / branch for the [1] and the
dependants (at least one more, which is sata_dwc_460ex).

The series can be reached in the branch located at [2].

Since v1:
- address most of Peter's comments (mostly changelog to patch 8)
- add tag to patch 5
- drop patch 6 from the series to be separately dealt with

Andy Shevchenko (11):
  dmaengine: dw: keep copy of custom slave config in dwc
  dmaengine: dw: provide probe(), remove() stubs for users
  dmaengine: dw: set polarity of handshake interface
  dmaengine: dw: override LLP support if asked in platform data
  serial: 8250_dma: switch to new dmaengine_terminate_* API
  serial: 8250_dma: adjust DMA address of the UART
  serial: 8250: enable AFE on ports where FIFO is 16 bytes
  serial: 8250_lpss: split LPSS driver to separate module
  serial: 8250_lpss: move Quark code from PCI driver
  serial: 8250_lpss: enable MSI for Intel Quark
  serial: 8250_lpss: enable DMA on Intel Quark UART
