Changes from v5:
* Checked the return value of wait_for_completion_timeout
* Removed the bus-delay devicetree parameter. After reviewing this logic
in detail, we found a bug in the formulae involving the bus delay. Moreover,
this parameter is not used by any product in the wild.

Maybe I'm missing something, but I think your i2c adapter is probed with
a subsys_initcall (as many other adapters). Otherwise, I can't see why
it would be probed before the the gpio c

This patchset adds a new adapter driver supporting the Imagination Technologies
I2C Serial Control Bus (SCB) controller.
The driver supports the usual FIFO-based mode of operation (so-called automatic

In other words, there's no need to use the _noirq hooks to get a suspend/resume
device/adapter order.
This commit changes this by using the suspend/resume PM hooks in the I2C
adapter.
