Hi,
We have some new platforms that don't provide separate PCI device for
the Integrated DMA Engine on Intel MID UART. It was not practical to
add support for them into 8250_pci.c, which is why I'm proposing that
we split it into separate probe driver.
The series includes some modifications to the hsu dma engine driver,
but the idea is that this would go trhu the serial tree.
Changes since v1:
- Fixed the incorrect register offset as pointed out by Andy.
- Fixed also driver/dma/hsu/pci.c as it still used the hsu platform data.
- Added ACKs from Vinod.
Heikki Krogerus (5):
serial: 8250_pci: Intel MID UART support to its own driver
dmaengine: hsu: make the UART driver in control of selecting this
driver
dmaengine: hsu: introduce stubs for the exported functions
dmaengine: hsu: remove platform data
serial: 8250_mid: add support for DMA engine handling from UART MMIO
