The driver recently learned to handle platform ids. Make use of this
new feature. The up side is that the driver needs less knowledge about
the spi interfaces used on different SoCs.

Group soc specific data in a global struct instead of repeating it for
each call to imxXX_add_spi_imxX. The structs holding the actual data
are placed in .init.constdata and so don't do much harm. Compared to
the previous approach this reduces code size to call imx_add_spi_imx.

* 'at91-fixes-for-linus' of git://github.com/at91linux/linux-2.6-at91:
AT91: at91sam9261ek: remove C99 comments but keep information
AT91: at91sam9261ek board: remove warnings related to use of SPI or SD/MMC
AT91: dm9000 initialization update
AT91: SAM9G45 - add a separate clock entry for every single TC block
AT91: clock: peripheral clocks can have other parent than mck
AT91: change dma resource index
The sd/mmc data structure is not used if SPI is selected. The configuration
of PIO on the board prevent from using both interfaces at the same time
(board dependent).
Remove the warnings at compilation time adding a preprocessor condition.

Partially revert e69edc7, which introduced automatic zreladdr

seems to be error and conflict prone. Go back to the original way
we were handling this for the time being, while keeping the automatic

Dave Hylands reports:
| We've observed a problem with dma_alloc_writecombine when the system
| is under heavy load (heavy bus traffic). We've managed to reduce the
| problem to the following snippet, which is run from a kthread in a
| continuous loop:
|
| void *virtAddr;
| dma_addr_t physAddr;
| unsigned int numBytes = 256;
|
| for (;;) {
| virtAddr = dma_alloc_writecombine(NULL,
| numBytes, &physAddr, GFP_KERNEL);
| if (virtAddr == NULL) {
| printk(KERN_ERR "Running out of memory\n");
| break;
| }
|
| /* access DMA memory allocated */
| tmp = virtAddr;
| *tmp = 0x77;
|
| /* free DMA memory */
| dma_free_writecombine(NULL,
| numBytes, virtAddr, physAddr);
|
| ...sleep here...
| }
|
| By itself, the code will run forever with no issues. However, as we
| increase our bus traffic (typically using DMA) then the *tmp = 0x77
| line will eventually cause a page fault. If we add a small delay (a
| few microseconds) before the *tmp = 0x77, then we don't see a page
| fault, even under heavy load.
A dsb() is required after modifying the PTE entries to ensure that they
will always be visible. Add this dsb().

Commit 7cfe24947 ("ARM: AMBA: Add pclk support to AMBA bus
infrastructure") changed AMBA bus to handle the PCLK automatically.
However, in EP93xx clock initialization is arch_initcall which is done
later than AMBA device identification. This causes
amba_get_enable_pclk() to fail resulting device where UARTs are not
functional.
So change ep93xx_clock_init() to be postcore_initcall.

The validate_event function in the ARM perf events backend has the
following problems:
1.) Events that are disabled count towards the cost.
2.) Events associated with other PMUs [for example, software events or
breakpoints] do not count towards the cost, but do fail validation,
causing the group to fail.
This patch changes validate_event so that it ignores events in the
PERF_EVENT_STATE_OFF state or that are scheduled for other PMUs.
