as we always want to take critical_section, and it is not long time job,
take mutex is not necessary, use spinlock_irq_save as a replace is
better, dont't have to take global critial_section in pm.

When initialising the SJA1000 peripheral on some implementations
(SJA1000_FDTOL), "releasing" the buffer when the Rx buffer is empty
causes a buffer pointer misalignment.
On peripheral initialise, remove the flag to "release" the buffer.
This should be safe for all systems using the SJA1000 CAN controller
as a "reset" to the peripheral clears the Rx FIFO.

After change, when CONFIG_PM_NDOMAINS > 1,
the pm_register will not able to get notificaion
from not PM_IDLE_DOMAIN.
Should use pm_domain_register as a replacement.
Isolate domains from global callbacks can decrease
not necessary execution, and reduce the
lock instruction requirements.

MCP794XX supports digital trimming that periodically adds or subtracts
clock cycles, resulting in small adjustments in the internal timing.
This way inaccuracies of clock source can be compensated.
This commit adds option to set the trimming register for MCP794XX.

This commit adds configuration option CONFIG_MCP794XX_DATETIME_UTC.
If set, the datetime is stored in UTC instead of local time. The
default value is kept at local time to keep backwards compatibility
with devices currently using the RTC.

DAC driver uses CONFIG_DAC_FIFOSIZE, but this is not configurable
from Kconfig. This adds the missing option and allows to set DAC
FIFO size from the configuration.

only when first time change state can hold WFI for enough time thresh,
allow second time goto target state,
suitable for the case when wakeup from sleep too slow, etc.

There is no need to call rwb->rhreloade() when nblocks is 0,
and some platform(eg: BES) has the limit that the parameter
of len in pltatform flash read function cant't be 0.
Swap the sequence of domain state update and statechanged callback,
Make sure inside statechanged callback can get the old domain state.

Some drivers may set too big quota by accident and consume all of our
buffers, so we add a check when registering devices.

Fix a bug which causes that 1-bit mode is always selected.
This happens even if the driver sets SDIO_CAPS_4BIT capability
in case of the card and the host support 1- and 4-bit wide bus.
