[PATCH 0/3 v3] spi: controller driver for Designware SPI core and PCI interface

[Feng Tang <feng.tang-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>]

Hi all,

This patch series adds driver for Designware SPI core + PCI interface, and
they are generated against kernel 2.6.32-rc4

0001: driver for the DW SPI core
0002: driver for PCI interface
0003: add DMA support

This driver has been verified on Intel Moorestown platform, with Maxim's
Max3110 UART device and Option's 3G modem GTM501L, both PIO and DMA works
fine, and these 2 slave devcies can work simultaneously.

0003 is RFC only, as it has dependency over DMA controller driver's acceptance
to mainline.

User can use "dw_apb_ssi_db.pdf" from Synopsys as HW datasheet

please help to review them.

---------------
change history:
	v3
	* address some review comments from Andrew Morton
	
	v2
	* divide the original one driver to "core+interface" framework
	  according to David's comments

	v1
	* initial submission 

Thanks,
Feng
