Address the following issues:
- imx_drm_encoder_get_mux_id() searches the CRTC list for the matching
CRTC, and returns the position within this list as the MUX programming
value for encoders. This is sub-optimal for two reasons:
1. It relies upon the CRTC list not changing during the lifetime of
the driver.
2. It is dependent on the initialisation order of the CRTCs.
We address (1) in this patch, leaving (2) until a better solution can
be found, as (2) requires larger changes.
- imx_drm_encoder is unused. Instead, pass the drm_encoder which is
slightly more useful; all callers pass encoder->crtc as the required
crtc, so move this inside the function.

The DI clock selection was very rudimentary: it would statically use
either the IPU internal clock or the DI external clock depending on
which "encoder" was being used. In the case of HDMI, it would always
use the IPU clock.
Moreover, using the IPU clock resulted in fractional divisors, which
are achieved by skipping clock pulses. This can result in the HDMI
PHY PLL being frequency modulated, and the attached device is then
unable to properly lock on to the TMDS clock.
We need at least 1% accurate and stable clocks for HDMI.
Arrange for the DI clock to be sourced from the IPU internal clock
if it can satisfy our requirements, otherwise switch to the DI
external clock and try and set the external clock to our desired
pixel clock rate.

Pull DMA mask updates from Russell King:
"This series cleans up the handling of DMA masks in a lot of drivers,
fixing some bugs as we go.
Some of the more serious errors include:
- drivers which only set their coherent DMA mask if the attempt to
set the streaming mask fails.
- drivers which test for a NULL dma mask pointer, and then set the
dma mask pointer to a location in their module .data section -
which will cause problems if the module is reloaded.
To counter these, I have introduced two helper functions:
- dma_set_mask_and_coherent() takes care of setting both the
streaming and coherent masks at the same time, with the correct
error handling as specified by the API.
- dma_coerce_mask_and_coherent() which resolves the problem of
drivers forcefully setting DMA masks. This is more a marker for
future work to further clean these locations up - the code which
creates the devices really should be initialising these, but to fix
that in one go along with this change could potentially be very
disruptive.
The last thing this series does is prise away some of Linux's addition
to "DMA addresses are physical addresses and RAM always starts at
zero". We have ARM LPAE systems where all system memory is above 4GB
physical, hence having DMA masks interpreted by (eg) the block layers
as describing physical addresses in the range 0..DMAMASK fails on
these platforms. Santosh Shilimkar addresses this in this series; the
patches were copied to the appropriate people multiple times but were
ignored.
Fixing this also gets rid of some ARM weirdness in the setup of the
max*pfn variables, and brings ARM into line with every other Linux
architecture as far as those go"
