i2c: Add support for Qualcomm Generic Interface (GENI) I2C controller
Add Support for the Qualcomm Generic Interface (GENI) I2C interface
found on newer Qualcomm SoCs.
The Generic Interface (GENI) is a firmware based Qualcomm Universal
Peripherals (QUP) Serial Engine (SE) Wrapper which can support multiple
bus protocols depending on the firmware type loaded at early boot time
based on system configuration.
It also supports the "I2C Master Hub" which is a single function Wrapper
that only FIFO mode I2C.
It replaces the fixed-function QUP Wrapper found on older SoCs.
The geni-se.h containing the generic GENI Serial Engine registers defines
is imported from Linux.
Only FIFO mode is implemented, neither SE DMA nor GPI DMA are implemented.
