This adds binding, driver and the DT support for the Lenovo Yoga C630 Embedded Controller, to provide battery information. Support for this EC was implemented by Bjorn, who later could not work on this driver. I've picked this patchset up and updated it following the pending review comments. DisplayPort support is still not a part of this patchset. It uses EC messages to provide AltMode information rather than implementing corresponding UCSI commands. However to have a cleaner uAPI story, the AltMode should be handled via the same Type-C port. Merge strategy: the driver bits depend on the platform/arm64 patch, which adds interface for the subdrivers. I'd either ask to get that patch merged to the immutable branch, which then can be picked up by power/supply and USB trees or, to make life simpler, ack merging all driver bits e.g. through USB subsystem (I'm biased here since I plan to send more cleanups for the UCSI subsystem, which would otherwise result in cross-subsystem conflicts). --- Changes in v3: - Split the driver into core and power supply drivers, - Added UCSI driver part, handling USB connections, - Fixed Bjorn's address in DT bindings (Brian Masney) - Changed power-role for both ports to be "dual" per UCSI - Link to v2: https://lore.kernel.org/linux-arm-msm/20230205152809.2233436-1-dmitry.baryshkov@xxxxxxxxxx/ Changes in v2: - Dropped DP support for now, as the bindings are in process of being discussed separately, - Merged dt patch into the same patchseries, - Removed the fixed serial number battery property, - Fixed indentation of dt bindings example, - Added property: reg and unevaluatedProperties to the connector bindings. - Link to v1: https://lore.kernel.org/linux-arm-msm/20220810035424.2796777-1-bjorn.andersson@xxxxxxxxxx/ --- Bjorn Andersson (2): dt-bindings: power: supply: Add Lenovo Yoga C630 EC arm64: dts: qcom: c630: Add Embedded Controller node Dmitry Baryshkov (4): platform: arm64: add Lenovo Yoga C630 WOS EC driver usb: typec: ucsi: add Lenovo Yoga C630 glue driver power: supply: lenovo_yoga_c630_battery: add Lenovo C630 driver arm64: dts: qcom: sdm845: describe connections of USB/DP port .../bindings/power/supply/lenovo,yoga-c630-ec.yaml | 83 ++++ arch/arm64/boot/dts/qcom/sdm845.dtsi | 53 ++- .../boot/dts/qcom/sdm850-lenovo-yoga-c630.dts | 76 ++++ drivers/platform/arm64/Kconfig | 14 + drivers/platform/arm64/Makefile | 1 + drivers/platform/arm64/lenovo-yoga-c630.c | 279 ++++++++++++ drivers/power/supply/Kconfig | 9 + drivers/power/supply/Makefile | 1 + drivers/power/supply/lenovo_yoga_c630_battery.c | 476 +++++++++++++++++++++ drivers/usb/typec/ucsi/Kconfig | 9 + drivers/usb/typec/ucsi/Makefile | 1 + drivers/usb/typec/ucsi/ucsi_yoga_c630.c | 189 ++++++++ include/linux/platform_data/lenovo-yoga-c630.h | 42 ++ 13 files changed, 1232 insertions(+), 1 deletion(-) --- base-commit: 8314289a8d50a4e05d8ece1ae0445a3b57bb4d3b change-id: 20240527-yoga-ec-driver-76fd7f5ddae8 Best regards, -- Dmitry Baryshkov <dmitry.baryshkov@xxxxxxxxxx>
