f2292532a5 mxc : BUG in imx_dma_request
On MX2 platforms imx_dma_request() calls request_irq() which may sleep
with interrupts disabled.

de0096d809 mxc : Clean up properly when imx_dma_free() used without imx_dma_disable()
The sequence
	imx_dma_request()
	imx_dma_enable()
	imx_dma_free()
left the dma channel in_use mode and did not release the timer.

e65fb0099f [ARM] MXC: remove _clk suffix from clock names
The context makes it clear already that these are clocks, so there's
no need for such a suffix. This patch only changes the clocks actually
used in the tree. The remaining clocks are renamed in the subsequent
architecture specific patches.

dcea83adc6 [ARM] Hide ISA DMA API when ISA_DMA_API is unset
When ISA_DMA_API is unset, we're not implementing the ISA DMA API,
so there's no point in publishing the prototypes via asm/dma.h, nor
including the machine dependent parts of that API.

This allows us to remove a lot of mach/dma.h files which don't contain
any useful code.  Unfortunately though, some platforms put their own
private non-ISA definitions into mach/dma.h, so we leave these behind
and fix the appropriate #include statments.

58a85f465f MX2: Add DMA support for mx2 and (eventually) mx1
This patch adds DMA support for Freescale i.MX27 SoCs. It is derived
from the i.MX1 port and should (though currently untested) still be
working for the i.MX1.
