SDIO cards may need clock to send the card interrupt to host.
Thus, we get runtime pm when sdio irq is enabled to prevent the clock
resource is released and put it when sdio irq is disabled.
The uSDHC has an ADMA Length Mismatch errata ERR004536 which may cause ADMA
work abnormally. The errata has already been fixed for i.MX6Q TO1.2

If uDMA is running, software set TDAR may cause tx hang.
If uDMA is in idle, software set TDAR don't cause tx hang.
There is a TDAR race condition for mutliQ when the software sets TDAR
and the UDMA clears TDAR simultaneously or in a small window (2-4 cycles).
This will cause the udma_tx and udma_tx_arbiter state machines to hang.

ENGR00273838-7 ASoC: fsl: Use hw_params() and hw_free() to set FLL
We followed community way by using set_bias() to set FLL of WM8962.
But this can't meet our requirement: aplay -Dhw: 16khz.wav 24khz.wav.
Thus use hw_params() and hw_free() instead.

ASoC: wm8962: Let CODEC driver enable and disable its own MCLK
snd_soc_open() will trigger pm_runtime resume() which will then enable
the regulator and initialization. So we should make sure the MCLK is
enabled before this resume().
Previously we let the machine driver get the clock and enable it in
its probe(). However, considering about power saving, it'll be better
to enable it when it's going to be used and disable it after using.
So this patch just simply adds clk_get() and clk_enable() to WM8962
driver. Meanwhile, it marks clock pointer to NULL if no clock assigned
to it so it will not break any current function.

ENGR00331635-1: dma: imx-sdma: Add imx6sx platform support
The new Solo X has more requirements for SDMA events. So it creates a event mux
to remap most of event numbers in GPR (General Purpose Register). If we want to
use SDMA support for those module who do not get the even number as default, we
need to configure GPR first.
Thus this patch adds this support of GPR event remapping configuration to the
SDMA driver.
