The DAI mode is and should be configured by the sound card driver as
codec and ssi have to be in the right modes to communicate with each
other. It is possible to operate the ssi unit or the codec in master mode,
sometimes even on the same board in different configurations.
With the latest changes in the fsl-ssi driver, the 'fsl,mode' property
is only handled as a fallback property. If the sound card sets the DAI
mode correctly, this fallback configuration is dropped.

The S/PDIF rxtx4 and rxtx6 clock inputs are "ESAI_HCKT" and "MLB clock",
respectively, according to the SoC documentation, and they are currently
mapped to clocks "esai" and "mlb".
However, they do not seem to actually work correctly. Testing on a
Cubox-i system with fsl_spdif driver forced to select one of those as
input will result in I/O errors on audio playback, which I believe means
missing clock signal.
Possibly the "ESAI_HCKT" and "MLB clock" refer to some other clocks
related to ESAI and MLB, or we are missing something else.
Since audio playback will not work if fsl_spdif selects these clocks
(which happens rarely), set the inputs do dummy clocks, at least for
now.

The rxtx2 clock of i.MX6 S/PDIF is currently set to "asrc" clock.
However, according to SoC documentation, rxtx2 is connected to
ASRC_EXT_CLK, a different external clock.
Testing on Cubox-i system seems to confirm that: when fsl_spdif is
forced to select rxtx2 as input clock, audio playback fails with an I/O
error.
Set rxtx2 to the dummy clock by default to prevent fsl_spdif from
selecting it.

Most peripherals on the i.MX53 have an
Off-Platform Peripheral Access Control Register (OPACR)
in which the access rights (together with the MPROT registers) can be declared.
However, this does not seem to work for example for SSI1+SDMA, because the
supervisor bit is not set for the SDMA unit.
It does work for SSI2, the QSB for example uses SSI2 for its audio. But SSI2 only
works because it does NOT have an OPACR.
The right solution would be to fix the access rights for the SDMA, but the unit
responsible for this is the Central Security Unit (CSU), which of course is NOT
documented. So, until documentation for this is openly available, turn off the
supervisor protection because it cripples the hardware.

The i.MX SoCs allow to setup fine grained access rights to peripherals on the
AIPS bus.
This is done via the Peripheral Access Register (PAR) in e.g. the i.MX21
or in later SoC versions the Off-Platform Peripheral Access Control Register
(OPACR), e.g. i.MX53.
Under certain circumstances this leads to problems in which bus masters are
not granted their access rights to peripherals.
To be able to disable these restrictions on DT platforms, add a helper function
that looks for AIPS nodes in the DT and disables them for every compatible node
it finds.
The compatible has to be declared in the mach-specific entry file, where this
helper function should then be called.

imx6q_pm_enter calls imx6sl_set_wait_clk when run on an imx6sl
based machine. However if support for imx6sl is not enabled
at compile time, this prevents us from building the kernel and
we get this link error instead:
arch/arm/mach-imx/built-in.o: In function `imx6q_pm_enter':
:(.text+0x4b84): undefined reference to `imx6sl_set_wait_clk'
This makes the cpu_is_imx6sl function conditionally return false
if imx6sl is disabled at compile-time, which matches what the
older cpu_is_mx* macros did. We have similar inline functions for
the other imx6 variants, but so far I have not run into a case
where the extra #ifdef is necessary.
