[ARM] 3455/1: ARM: OMAP: 7/8 Misc updates, take 2 Patch from Tony Lindgren Update misc OMAP core code from linux-omap tree: - McBSP updates by Samuel Ortiz, Andrzej Zaborowski - Whitespace cleanups by Ladislav Michl - Other fixes by various linux-omap developers Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

OMAP2420: hwmod data: Add McSPI Update the omap2420 hwmod data with the McSPI info. Add a device attribute structure which will be used for passing number of chipselects from hwmod data. Add revision macros to be passed from rev field from hwmod.

OMAP: devices: Modify McSPI device to adapt to hwmod framework Cleans up all base address definitions for omap_mcspi and adapts the device registration and driver to hwmod framework. Changes involves: 1) Removing all base address macro defines. 2) Using omap-device layer to register device and utilizing data from hwmod data file for base address, dma channel number, Irq_number, device attribute(number of chipselect). 3) Appending base address with pdata reg_offset for omap4 boards. For omap4 all regs used in driver deviate with reg_offset_macros defined with an value of 0x100. So pass this offset through pdata and append the same to base address retrieved from hwmod data file and we are not mapping *_HL_* regs which are not used in driver.
