The psi monitoring patches will need to determine the same states as

Thank you for the v2.
I will probably submit v3 outside the realm of the multi color framework.
We can always convert as Pavel pointed out.

The final ternary expression is given void * and type * as arguments, so
the resulting type of the macro ends up being void *.
container_of returns a type which maches the argument, this provides type
safety and allows the expression to be immediately used as the target
type.

Tegra I2C TX and RX FIFO depth is 8 words. PIO mode is used for
transfer size of the max FIFO depth and DMA mode is used for

PIO mode needs full intervention of CPU to fill or empty FIFO's
