The cros_usbpd-charger already supports limiting input current, so we can easily extend it as a passive thermal cooling device. By limiting the current flow into the system, we can reduce the heat generated by related chips, which results in reserving more thermal budget for the system. This series will only works on making it a OF style thermal cooling device, so related code are guarded by #ifdef macros. --- Changes in v2: - Revise commit message for including the reason of change for this series. - Remove uses of `ifdef CONFIG_THERMAL_OF`, and use `IS_ENABLED(CONFIG_THERMAL_OF)` when needed. - Does not failing the driver probing if failed to register the usbpd device as a cooling device. --- Sung-Chi Li (2): power: supply: cros_usbpd-charger: extend as a thermal of cooling device dt-bindings: mfd: cros-ec: add properties for thermal cooling cells .../devicetree/bindings/mfd/google,cros-ec.yaml | 3 + drivers/power/supply/cros_usbpd-charger.c | 84 +++++++++++++++++++++- 2 files changed, 85 insertions(+), 2 deletions(-) --- base-commit: ac24e26aa08fe026804f678599f805eb13374a5d change-id: 20241122-extend_power_limit-62c2d9aabfa7 Best regards, -- Sung-Chi Li <lschyi@xxxxxxxxxxxx>
