This patch add support for property 'rockchip,no-dmaengine'.
it is a boolean property. if present, driver will do not
register pcm dmaengine, only just register dai. if the dai
is part of multi-dais, the property should be present. Please
refer to rockchip,multidais.txt about multi-dais usage.

This patch fixup that the wrong position when dma desc status
is DONE. even if the desc status is DONE, it is still able to
get the position from the dma driver. so, just remove the judgement.

This is because set_fmt ops maybe called when PD is off,
and in such case, regmap_ops will lead system hang.
enale PD before doing regmap_ops.

we found mclk maybe not precise as required because of PLL,
but it still can be used and no side effect. for example, if we
require mclk 11289600, but get 11289598, it doesn't matter.
so using DIV_ROUND_CLOSEST to fix it.

Based on the TSADC Tshut mode to select pinctrl,
instead of setting pinctrl based on architecture
(Not depends on pinctrl setting by "init" or "default").
And it requires setting the tshut polarity before select pinctrl.

to cope with Wide Temperature Range test, we maxamize
soc's sw/hw over temperature power off degree.
fow now, 115 degree Celsius is set to trigger sw powering off.
if sw function does not work and temperature is continuing to
grow up, and till 120 degree Celsius, hw powering off/reset
is triggered.

If the device has a 'power-domains' property that the power framework
prefer to use dev_pm_ops for suspend&resume. The legacy suspend & resume
callback for nandc driver would not be used.
Anyway, it's better use dev_pm_ops whether 'power-domains' is existent.
