2025-05-09soc: qcom: pmic_glink_altmode: fix spurious DP hotplug eventsJohan Hovold
The PMIC GLINK driver is currently generating DisplayPort hotplug notifications whenever something is connected to (or disconnected from) a port regardless of the type of notification sent by the firmware. These notifications are forwarded to user space by the DRM subsystem as connector "change" uevents: KERNEL[1556.223776] change /devices/platform/soc@0/ae00000.display-subsystem/ae01000.display-controller/drm/card0 (drm) ACTION=change DEVPATH=/devices/platform/soc@0/ae00000.display-subsystem/ae01000.display-controller/drm/card0 SUBSYSTEM=drm HOTPLUG=1 CONNECTOR=36 DEVNAME=/dev/dri/card0 DEVTYPE=drm_minor SEQNUM=4176 MAJOR=226 MINOR=0 On the Lenovo ThinkPad X13s and T14s, the PMIC GLINK firmware sends two identical notifications with orientation information when connecting a charger, each generating a bogus DRM hotplug event. On the X13s, two such notification are also sent every 90 seconds while a charger remains connected, which again are forwarded to user space: port = 1, svid = ff00, mode = 255, hpd_state = 0 payload = 01 00 00 00 00 00 00 ff 00 00 00 00 00 00 00 00 Note that the firmware only sends on of these when connecting an ethernet adapter. Fix the spurious hotplug events by only forwarding hotplug notifications for the Type-C DisplayPort service id. This also reduces the number of uevents from four to two when an actual DisplayPort altmode device is connected: port = 0, svid = ff01, mode = 2, hpd_state = 0 payload = 00 01 02 00 f2 0c 01 ff 03 00 00 00 00 00 00 00 port = 0, svid = ff01, mode = 2, hpd_state = 1 payload = 00 01 02 00 f2 0c 01 ff 43 00 00 00 00 00 00 00 Fixes: 080b4e24852b ("soc: qcom: pmic_glink: Introduce altmode support") Cc: stable@vger.kernel.org # 6.3 Cc: Bjorn Andersson <andersson@kernel.org> Reported-by: Clayton Craft <clayton@craftyguy.net> Signed-off-by: Johan Hovold <johan+linaro@kernel.org> Acked-by: Konrad Dybcio <konrad.dybcio@oss.qualcomm.com> Tested-by: Clayton Craft <clayton@craftyguy.net> Link: https://lore.kernel.org/r/20250324132448.6134-1-johan+linaro@kernel.org Signed-off-by: Bjorn Andersson <andersson@kernel.org>

2025-05-07soc: qcom: pmic_glink: enable UCSI on sc8280xpJohan Hovold
Commit ad3dd9592b2a ("soc: qcom: pmic_glink: disable UCSI on sc8280xp") disabled UCSI shortly after it had been enabled to fix a regression that was observed on the Lenovo ThinkPad X13s. Specifically, disconnecting an external display would trigger a system error and hypervisor reset but no one cared enough to track down the bug at the time. The same issue was recently observed on X Elite machines, and commit f47eba045e6c ("usb: typec: ucsi: Set orientation as none when connector is unplugged") worked around the underlying issue by setting the connector orientation to 'none' on disconnect events to avoid having the PHY driver crash the machine in one orientation. Enable UCSI support also on sc8280xp now that the DisplayPort disconnect crashes are gone.

2025-05-04soc: Add VIA/WonderMedia SoC identification driverAlexey Charkov
Add a small SOC bus driver to parse the chip ID and revision made available on VIA/WonderMedia SoCs via their system configuration controller's SCC_ID register. This is intended to select appropriate sets of on-chip device quirks at runtime, as it has been found that even within the same SoC version there can be register-incompatible differences, such as with the SDMMC controller on WM8505 rev. A0-A1 vs. rev. A2. The list of SoC versions is compiled from various vendor source dumps and not all of them have corresponding mainline driver support. Some of them also have been seen with varying on-chip markings while sharing the same hardware chip ID's (as is the case with e.g. WM8850 vs. WM8950). In such cases the selection of names to use here among those seen in various source dumps and chip markings was arbitrary. Suggested by Krzysztof at [1] - thanks a lot!

2025-04-11scsi: soc: qcom: ice: Add HWKM support to the ICE driverGaurav Kashyap
Qualcomm's Inline Crypto Engine (ICE) version 3.2 and later includes a key management hardware block called the Hardware Key Manager (HWKM). Add support for HWKM to the ICE driver. HWKM provides hardware-wrapped key support where the ICE (storage) keys are not exposed to software and instead are protected in hardware. Later patches will wire up this feature to ufs-qcom and sdhci-msm using the support added in this patch. HWKM and legacy mode are currently mutually exclusive. The selection of which mode to use has to be made before the storage driver(s) registers any inline encryption capable disk(s) with the block layer (i.e., generally at boot time) so that the appropriate crypto capabilities can be advertised to upper layers. Therefore, make the ICE driver select HWKM mode when the all of the following are true: - The new module parameter qcom_ice.use_wrapped_keys=1 is specified. - HWKM is present and is at least v2, i.e. ICE is v3.2.1 or later. - The SCM calls needed to fully use HWKM are supported by TrustZone.

2025-04-11scsi: soc: qcom: ice: Make qcom_ice_program_key() take struct blk_crypto_keyEric Biggers
qcom_ice_program_key() currently accepts the key as an array of bytes, algorithm ID, key size enum, and data unit size. However both callers have a struct blk_crypto_key which contains all that information. Thus they both have similar code that converts the blk_crypto_key into the form that qcom_ice_program_key() wants. Once wrapped key support is added, the key type would need to be added to the arguments too. Therefore, this patch changes qcom_ice_program_key() to take in all this information as a struct blk_crypto_key directly. The calling code is updated accordingly. This ends up being much simpler, and it makes the key type be passed down automatically once wrapped key support is added. Based on a patch by Gaurav Kashyap <quic_gaurkash@quicinc.com> that replaced the byte array argument only. This patch makes the blk_crypto_key replace other arguments like the algorithm ID too, ensuring that there remains only one source of truth.
