Merge branch '20260227061544.1785978-1-praveen.talari@oss.qualcomm.com' into drivers-for-7.2

2026-05-22T03:00:31+00:00

Merge the refactoring and helper functions in the Qualcomm GENI Serial
Engine driver through a topic branch.

These changes will provide the ability to add support managing power and
performance for the GENI instances in platforms where these are
controlled as SCMI resources.

The patches are merged through a topic branch to avoid conflicts with other
changes, while making them available to other subsystems.

soc: qcom: geni-se: Introduce helper APIs for performance control

2026-05-22T02:56:38+00:00

The GENI Serial Engine (SE) drivers (I2C, SPI, and SERIAL) currently
manage performance levels and operating points directly. This resulting
in code duplication across drivers. such as configuring a specific level
or find and apply an OPP based on a clock frequency.

Introduce two new helper APIs, geni_se_set_perf_level() and
geni_se_set_perf_opp(), addresses this issue by providing a streamlined
method for the GENI Serial Engine (SE) drivers to find and set the OPP
based on the desired performance level, thereby eliminating redundancy.

soc: qcom: geni-se: Introduce helper API for attaching power domains

2026-05-22T02:56:38+00:00

The GENI Serial Engine drivers (I2C, SPI, and SERIAL) currently handle
the attachment of power domains. This often leads to duplicated code
logic across different driver probe functions.

Introduce a new helper API, geni_se_domain_attach(), to centralize
the logic for attaching "power" and "perf" domains to the GENI SE
device.

soc: qcom: geni-se: Add resources activation/deactivation helpers

2026-05-22T02:56:38+00:00

The GENI SE protocol drivers (I2C, SPI, UART) implement similar resource
activation/deactivation sequences independently, leading to code
duplication.

Introduce geni_se_resources_activate()/geni_se_resources_deactivate() to
power on/off resources.The activate function enables ICC, clocks, and TLMM
whereas the deactivate function disables resources in reverse order
including OPP rate reset, clocks, ICC and TLMM.

soc: qcom: geni-se: Introduce helper API for resource initialization

2026-05-22T02:56:38+00:00

The GENI Serial Engine drivers (I2C, SPI, and SERIAL) currently duplicate
code for initializing shared resources such as clocks and interconnect
paths.

Introduce a new helper API, geni_se_resources_init(), to centralize this
initialization logic, improving modularity and simplifying the probe
function.

soc: qcom: geni-se: Add geni_icc_set_bw_ab() function

2026-05-22T02:56:38+00:00

Add a new function geni_icc_set_bw_ab() that allows callers to set
average bandwidth values for all ICC (Interconnect) paths in a single
call. This function takes separate parameters for core, config, and DDR
average bandwidth values and applies them to the respective ICC paths.

This provides a more convenient API for drivers that need to configure
specific average bandwidth values.
