This bus driver supports the QUP i2c hardware controller in the Qualcomm
MSM SOCs. The Qualcomm Universal Peripheral Engine (QUP) is a general
purpose data path engine with input/output FIFOs and an embedded i2c
mini-core. The driver supports FIFO mode (for low bandwidth applications)
and block mode (interrupt generated for each block-size data transfer).
The driver currently does not support DMA transfers.

v2: updates to runtime PM calls (addresses comments from Mark Brown).
Disable interrupts before setting completion object to NULL (bug fix).

Hi Ben,

If there are no objections to this i2c driver, can it be pulled into your -next tree?

thank you,
