2023-08-10drm/i915/gt: Apply workaround 22016122933 correctlyJonathan Cavitt
WA_22016122933 was recently applied to all MeteorLake engines, which is simultaneously too broad (should only apply to Media engines) and too specific (should apply to all platforms that use the same media engine as MeteorLake). Correct this in cases where coherency settings are modified. There were also two additional places where the workaround was applied unconditionally. The change was confirmed as necessary for all platforms, so the workaround label was removed.

2023-08-10drm/i915: Make i915_coherent_map_type GT-centricJonathan Cavitt
Refactor i915_coherent_map_type to be GT-centric rather than device-centric. Each GT may require different coherency handling due to hardware workarounds. Since the function now takes a GT instead of the i915, the function is renamed and moved to the gt folder.

2023-08-10drm/i915/gt: Simplify shmem_create_from_object map_type selectionJonathan Cavitt
The object pin created for shmem_create_from_object is just a single use mapping with the sole purpose of reading the contents of the whole object in bulk. And the whole source object is also even a throw-away. Ergo, the additional logic required by i915_coherent_map_type can be safely dropped and simplified.

2023-08-10pinctrl: qcom: Add intr_target_width field to support increased number of ↵Ninad Naik
interrupt targets SA8775 and newer target have added support for an increased number of interrupt targets. To implement this change, the intr_target field, which is used to configure the interrupt target in the interrupt configuration register is increased from 3 bits to 4 bits. In accordance to these updates, a new intr_target_width member is introduced in msm_pingroup structure. This member stores the value of width of intr_target field in the interrupt configuration register. This value is used to dynamically calculate and generate mask for setting the intr_target field. By default, this mask is set to 3 bit wide, to ensure backward compatibility with the older targets.

2023-08-10drm/i915: fix display probe for IVB Q and IVB D GT2 serverJani Nikula
The current display probe is unable to differentiate between IVB Q and IVB D GT2 server, as they both have the same device id, but different subvendor and subdevice. This leads to the latter being misidentified as the former, and should just end up not having a display. However, the no display case returns a NULL as the display device info, and promptly oopses. As the IVB Q case is rare, and we're anyway moving towards GMD ID, handle the identification requiring subvendor and subdevice as a special case first, instead of unnecessarily growing the intel_display_ids[] array with subvendor and subdevice.

Note unfortunately on atomisp the _DSM to get the VCM type sometimes returns a VCM even though there is none. Since VCMs are typically only used together with certain sensors, work around this by adding a vcm field to atomisp_sensor_config and only check for a VCM when that is set.

acpi_handle_info() uses the ACPI path to the handle as prefix for messages e.g. : "\_SB_.I2C2.CAM8". This makes it hard for users to figure out which csi2-bridge messages belong to which sensor since the actual sensor drivers uses the ACPI device name (typically "HID:00") for logging. Extend the acpi_handle_info() (and err and warn) logging to also log the device name to make it easier to match csi2-bridge messages with sensor driver log messages.

Note this will also use / assume v4l2-async device instantiation for ov5693 sensors on atomisp devices since ipu_supported_sensors[] already contains a match for this. This is fine since recent atomisp improvements allow the atomisp code to work with generic v4l2 sensor drivers and using an unmodified drivers/media/i2c/ov5693.c has been successfully tested on an Acer Iconia W4 820 tablet with an ISP2400 + OV5693 sensor.

2023-08-10media: ipu-bridge: Add a runtime-pm device-link between VCM and sensorHans de Goede
In most cases when a VCM is used there is a single integrated module with the sensor + VCM + lens. This means that the sensor and VCM often share regulators and possibly also something like a powerdown pin. In the ACPI tables this is modelled as a single ACPI device with multiple I2cSerialBus resources. On atomisp devices the regulators and clks are modelled as ACPI power-resources, which are controlled by the (ACPI) power state of the sensor. So the sensor must be in D0 power state for the VCM to work. To make this work add a device-link with DL_FLAG_PM_RUNTIME flag so that the sensor will automatically be runtime-resumed whenever the VCM is runtime-resumed. This requires the probing of the VCM and thus the creation of the VCM I2C-client to be delayed till after the sensor driver has bound. Move the instantiation of the VCM I2C-client to the v4l2_async_notifier bound op, so that it is done after the sensor driver has bound; and add code to add the device-link. This fixes the problem with the shared ACPI power-resources on atomisp2 and this avoids the need for VCM related workarounds on IPU3 / IPU6. E.g. until now the dw9719 driver needed to get and control a Vsio (V sensor IO) regulator since that needs to be enabled to enable I2C pass-through on the PMIC on the sensor module. So the driver was controlling this regulator even though the actual dw9719 chip has no Vsio pin / power-plane. This also removes the need for ipu_bridge_init() to return -EPROBE_DEFER since the VCM is now instantiated later.
