Hi.

This patchset adds devicetree and slave mode support to pxa2xx SPI
controller. The objective is that it will be able to support the
OLPC XO 1.75 embedded controller that is a SPI master talking to a
MMP2 SOC. The EC driver will be submitted in a separate patch set
shortly.
 
These patches have been submitted previously, but not applied:

[PATCH v2 01/11] dt-bindings: spi/spi-pxa2xx: add PXA2xx SSP SPI
[PATCH v2 02/11] PCI: Provide pci_match_id() with CONFIG_PCI=n
[PATCH 03/11] spi: pxa2xx: Use an enum for type
[PATCH 04/11] spi: pxa2xx: Add devicetree support
[PATCH v2 05/11] DT: marvell,mmp2: Add SSP1 and SSP3

These are new:

[PATCH 06/11] dt-bindings: spi/spi-pxa2xx: Add spi-slave property
[PATCH 07/11] spi: Deal with slaves that return from transfer_one()
[PATCH 08/11] spi: pxa2xx: Add slave mode support
[PATCH 09/11] dt-bindings: spi/spi-pxa2xx: Add ready GPIO signal
[PATCH 10/11] spi: pxa2xx: Add ready signal
[PATCH 11/11] spi: pxa2xx: Deal with the leftover garbage in TXFIFO

Verified on a OLPC XO 1.75 machine.

Thank you,
Lubo
