[PATCH v7 0/6] Enable I2C on SA8255p Qualcomm platforms

[Praveen Talari]

The Qualcomm automotive SA8255p SoC relies on firmware to configure
platform resources, including clocks, interconnects and TLMM.
The driver requests resources operations over SCMI using power
and performance protocols.

The SCMI power protocol enables or disables resources like clocks,
interconnect paths, and TLMM (GPIOs) using runtime PM framework APIs,
such as resume/suspend, to control power states(on/off).

The SCMI performance protocol manages I2C frequency, with each
frequency rate represented by a performance level. The driver uses
geni_se_set_perf_opp() API to request the desired frequency rate..

As part of geni_se_set_perf_opp(), the OPP for the requested frequency
is obtained using dev_pm_opp_find_freq_floor() and the performance
level is set using dev_pm_opp_set_opp().
