PENDING: arm64: dts: qcom: nord: Add PMM8650AU and KAI_MV PMIC support
Add support for PMM8650AU and KAI_MV PMICs on nord-rrd and nord-ride-sx - new PMICs not present on lemans/monaco, so added new dtsi files (kai_mv-nord.dtsi, pmm8650au-nord.dtsi) with their peripheral definitions (MBG-temp, pon, rtc, gpio), updated nord.dtsi spmi_bus controller node accordingly and added matching compatible strings in the pinctrl-spmi-gpio driver.

sorry what is kai_mv-nord.dtsi ? What h/w module it represent. Please reuse dts/dtsi that represent h/w . On qli we donot refactor dt nodes based on tech area split.

Kai_mv is a new PMIC not present on lemans/monaco, so there was no existing dtsi to reuse - added kai_mv-nord.dtsi
for it. For Kobra (pmm8650au) is a different SIDs then lemans/monaco, so it also needed its own dtsi rather than reusing theirs.

Done - squashed the 7 commits into 2 (pinctrl driver change, DT/dtsi changes) with proper commit messages
describing each change. Pushed the update. Thanks

I saw that - https://lore.kernel.org/all/177939170556.182385.2422863350479004971.b4-ty@kernel.org/ Here they added kai_mv PMIC so renaming it to pmau0102.

drajpura269 I'm facing an issue on early/hwe/nord-next branch that PMIC interrupt never fires . I wonder whether you tested it good on staging/nord.

shawngsc · 2026-08-20T03:54:56Z

For which PMIC interrupt you are talking about? Can you once check with latest PR?

I'm seeing the issue with PMAU0102 GPIO_08 being interrupt line of FUSB15201 Type-C controller, but I suspect it's an issue with any PMIC interrupts, temp-alarm, pm8xxx_rtc_alarm or pmic_pwrkey. I just tested the latest of this PR with pm8xxx_rtc_alarm. It doesn't tick in /proc/interrupts after an alarm expires like echo +3 > /sys/class/rtc/rtc0/wakealarm.

drajpura269 · 2026-08-20T04:56:36Z

echo +3 > /sys/class/rtc/rtc0/wakealarm

Not sure what's setup difference but I can see the interrupt with the same command you gave.
root@qcom-armv8a:/sys/class/thermal# cat /proc/interrupts | grep rtc
364: 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 pmic_arb 6431274 Edge pm8xxx_rtc_alarm

Add the qcom,pmau0102 compatible string to the SPMI PMIC binding for the new PMIC used on Nord. PMM8650AU (Kobra) reuses the existing qcom,pmm8654au compatible, as confirmed to be the same PMIC. Signed-off-by: Dhruvin Rajpura <drajpura@qti.qualcomm.com>

please resolve the comment.

Add the qcom,pmau0102-gpio SPMI GPIO compatible string, with 12 GPIOs, for the new PMIC used on Nord. PMM8650AU (Kobra) reuses the existing qcom,pmm8654au-gpio compatible, as confirmed to be the same PMIC, so the driver already binds against it. Signed-off-by: Dhruvin Rajpura <drajpura@qti.qualcomm.com>

Add a qcom,pmau0102-mbg-tm compatible with qcom,pm8775-mbg-tm as fallback, so the MBG temperature monitor on PMAU0102 can be distinguished from the existing PM8775 MBG hardware while still binding against the same driver. Signed-off-by: Dhruvin Rajpura <drajpura@qti.qualcomm.com>

PMAU0102 and PMM8650AU are new PMICs used on nord-rrd and nord-ride-sx that are not present on lemans/monaco, so there is no existing dtsi to reuse. Add per-chip PMIC dtsi files (pmau0102-nord.dtsi, pmm8650au-nord.dtsi) with their peripheral definitions, matching the hardware-per-file convention used for other PMICs. Update the spmi_bus controller node in nord.dtsi accordingly and include the new per-chip dtsi files from nord-embedded.dtsi, shared by both nord-rrd.dts and nord-ride-sx.dts. PMAU0102 instances (pmau0102_e through pmau0102_l) get gpio, adc and an MBG(Master Bandgap) temperature monitor wired to a DIE_TEMP ADC channel, using the qcom,pmau0102-mbg-tm compatible with qcom,pm8775-mbg-tm as fallback. PMM8650AU (Kobra) is confirmed to be the same PMIC as PMM8654AU, so its instances reuse the existing qcom,pmm8654au and qcom,pmm8654au-gpio compatibles. The Kobra_MM instance (kobra_mm_a) gets pon, rtc, gpio and adc; apps does not have permission for its qcom,spmi-temp-alarm peripheral, so no thermal sensor is added for it. The Kobra_PSAIL instance (kobra_psail_b) gets an MBG temperature monitor wired to kobra_mm_a's DIE_TEMP ADC channel, since Kobra_PSAIL has no ADC of its own. Signed-off-by: Dhruvin Rajpura <drajpura@qti.qualcomm.com>

Enable qcom,spmi-adc5-gen3 and qcom,pm8775-mbg-tm so the PMAU0102 and PMM8650AU MBG temperature sensors and their backing ADC channels are built into the Nord kernel image. Signed-off-by: Dhruvin Rajpura <drajpura@qti.qualcomm.com>
