thermal/of: Rename the devm_thermal_of_cooling_device_register() function

2026-06-03T07:12:53+00:00

To clarify that the function operates on child nodes, rename: devm_thermal_of_cooling_device_register() | v devm_thermal_of_child_cooling_device_register() Used the command: find . -type f -name '*.[ch]' -exec \ sed -i 's/devm_thermal_of_cooling_device_register/\ devm_thermal_of_child_cooling_device_register/g' {} \; Did not used clang-format-diff because it does not indent correctly and checkpatch complained. Manually reindented to make checkpatch happy This prepares for upcoming support of cooling devices identified by an ID rather than device tree child nodes. No functional change.

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. Signed-off-by: Bjorn Andersson

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: Handle core clk in geni_se_clks_off() and geni_se_clks_on()

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

Currently, core clk is handled individually in protocol drivers like the I2C driver. Move this clock management to the common clock APIs (geni_se_clks_on/off) that are already present in the common GENI SE driver to maintain consistency across all protocol drivers. Core clk is now properly managed alongside the other clocks (se->clk and wrapper clocks) in the fundamental clock control functions, eliminating the need for individual protocol drivers to handle this clock separately.

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.
