On Glymur, the PMIC RTC alarm IRQ cannot be delivered over SPMI to
rtc-pm8xxx, because that permission is routed to the charger firmware
running on a remote subsystem instead. The rtc-glink driver requests
RTC time/alarm access over the existing PMIC GLINK channel to work
around this.

Enable CONFIG_RTC_DRV_QCOM_GLINK as a module so the reference arm64
defconfig covers this driver on Glymur.

This series adds a single defconfig change to enable the Qualcomm
PMIC GLINK RTC driver (CONFIG_RTC_DRV_QCOM_GLINK) in the arm64
reference defconfig, so that Glymur boards pick it up.

This depends on the rtc-glink driver and its DT-binding
documentation, currently posted upstream for review and not yet
merged into any tree:

  https://lore.kernel.org/all/20260807-rtc-glink-cleanup-v1-0-7801e4d69c4f@oss.qualcomm.com/

This patch should be applied on top of that series (or held until
it lands), since CONFIG_RTC_DRV_QCOM_GLINK does not exist without
it.

And how people should guess what is Glymur and why do we want this in
defconfig... Plus I do not believe that is even true - Glymur does not
have a PMIC.

Why Qualcommm - it's fourth or fifth posting now - invented such tag?

From where did you get it? Microslop tools?
