This series introduces a new driver to let the user retrieve current RPM of the two fans, the temperature readouts from 2 temperature sensors and get/let keyboard brightness levels. The driver also notifies the EC of system suspend entry/exit. Two separate compatibles are maintained since the two laptops' ECs seem to be generally alike, however assuming full compatibility with the limited available information does not spark confidence. Signed-off-by: Konrad Dybcio --- Changes in v4: - Make the byte order clearer for reads/writes. Sparse is happy. - Tweak the if-else near ASUS_EC_EVT_AC_STATE - Add the A14 DTS patch - Link to v3: https://patch.msgid.link/20260923-topic-asus_ec-v3-0-2bf3bb9da879@oss.qualcomm.com Changes in v3: - Cover Ilpo's feedback: includes, braces, dev_info->dev_dbg, line wrapping, reuse the timeout logic - Pick up tags - Reabse on next-20260922 (NOP) - Link to v2: https://patch.msgid.link/20260922-topic-asus_ec-v2-0-0bd923d1b853@oss.qualcomm.com Changes in v2: - Add rationale for separate compatibles - Drop `wakeup-source` from `required` in dt-bindings - Fix bindings example indentation - Rebase on next-20260921 (NOP) - Link to v1: https://patch.msgid.link/20260917-topic-asus_ec-v1-0-373516d347ae@oss.qualcomm.com To: Rob Herring To: Krzysztof Kozlowski To: Conor Dooley To: Konrad Dybcio To: Hans de Goede To: Ilpo Järvinen To: Bryan O'Donoghue To: Guenter Roeck To: Bjorn Andersson To: Abel Vesa Cc: devicetree@vger.kernel.org Cc: linux-kernel@vger.kernel.org Cc: platform-driver-x86@vger.kernel.org Cc: linux-hwmon@vger.kernel.org Cc: linux-arm-msm@vger.kernel.org --- Konrad Dybcio (4): dt-bindings: embedded-controller: Add ASUS Zenbook A16 EC platform: arm64: Add a driver for the EC found on ASUS Glymur machines arm64: dts: qcom: glymur-zenbook-a16: Add Embedded Controller arm64: dts: qcom: glymur-zenbook-a14: Add Embedded Controller .../asus,zenbook-a16-ux3607oa-ec.yaml | 64 +++ .../dts/qcom/glymur-asus-zenbook-a14-ux3407na.dts | 26 + .../dts/qcom/glymur-asus-zenbook-a16-ux3607oa.dts | 15 +- drivers/platform/arm64/Kconfig | 16 + drivers/platform/arm64/Makefile | 1 + drivers/platform/arm64/asus-glymur-ec.c | 616 +++++++++++++++++++++ 6 files changed, 736 insertions(+), 2 deletions(-) --- base-commit: 1fffefb00cc0b0da1f2ae24e3d33364530ea6515 change-id: 20260917-topic-asus_ec-065764978e77 Best regards, -- Konrad Dybcio
