Before enabling a muxing function, pin interrupt is disabled (probably
to prevent spurious interrupts). It can causes several issues mainly for
power management when switching from default to sleep state or the other
way around. So if the irq was enabled for a pin, restore it once pin has
been configured.

As .power() and .reset() function defined as a pair similar functions.
But the .reset() use the soc-camera device's dev as parameter.
And .power() use the i2c-client's dev.

This patch will pass the i2c-client's dev to .reset() function, same as
.power().

In commit:

    3078cde7

 can: at91_can: add dt support

device tree support was added to the at91_can driver. In this commit the
mapping of device to driver data was mixed up. This results in the sam9x5
parameters being used for the sam9263 and the workaround for the broken mailbox
0 on the sam9263 not being activated.

This patch fixes the broken platform_device_id table.

sam9x5 SoCs have the following errata:
 "RTC: Interrupt Mask Register cannot be used
  Interrupt Mask Register read always returns 0."

Hence we should not rely on what IMR claims about already masked IRQs
and just disable all IRQs.

2. As the i2c has known issue for 9g45, so we use i2c-gpio instead.

Allow the pin controller to handle and set the state of the pins to:
* "default" on boot, resume and before performing an transfer.
* "sleep" on suspend.

This should make it possible to optimize energy usage for the pins
both for the suspend/resume cycle.

pm: at91: pm_slowclock: move disabling the DDR clock after the code to disable the DDRC peripheral clock

It is verified on the SAMA5D4-EK that it is more reliable to disable DDR clock.

Since in SAMA5D4 chip, the PMECC can correct bit flips in erased page.
So we add a DT property to indicate this hardware charactor.

If the PMECC support correct bitflip erased page (all data are 0xff).
Then we can use the PMECC correct the page and skip the erased page
check.
