This series adds support for the Qualcomm I2C slave controller, a
dedicated hardware IP that operates exclusively as an I2C slave device
on the bus.
The controller supports FIFO (PIO) mode for data transfer and exposes
an SMBus interface to userspace via the standard I2C subsystem. It is
present on Qualcomm QDU1000 and related SoCs.
The series is structured as follows:
Patch 1: Device Tree binding document for the controller
Patch 2: Driver implementation including Kconfig and Makefile entries
Patch 3: MAINTAINERS entry
The driver has been tested on QDU1000 hardware with byte, word, and
block SMBus transfers.
