This bus driver supports the QUP i2c hardware controller in the Qualcomm 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). Signed-off-by: Ivan T.
