The caller expects panfrost_job_hw_submit() to increase runtime PM usage counter. The refcount decrement on the error branch of WARN_ON() will break the counter balance and needs to be removed. Signed-off-by:

The calls to panfrost_devfreq_record_busy() and panfrost_devfreq_record_idle() must be balanced to ensure that the devfreq utilisation is correctly reported. But there are two cases where this doesn't work correctly. In panfrost_job_hw_submit() if pm_runtime_get_sync() fails or the WARN_ON() fires then no call to panfrost_devfreq_record_busy() is made, but when the job times out the corresponding _record_idle() call is still made in panfrost_job_timedout(). Move the call up to ensure that it always happens. Secondly panfrost_job_timedout() only makes a single call to panfrost_devfreq_record_idle() even if it is cleaning up multiple jobs. Move the call inside the loop to ensure that the number of _record_idle() calls matches the number of _record_busy() calls.

The ti_sn_bridge_gpio_set() got the return value of regmap_update_bits() but didn't check it. The function can't return an error value, but we should at least print a warning if it didn't work.

The kernel test robot noted that if "OF" is defined (which is needed to select DRM_TI_SN65DSI86 at all) but not OF_GPIO that we'd get compile failures because some of the members that we access in "struct gpio_chip" are only defined "#if defined(CONFIG_OF_GPIO)". All the GPIO bits in the driver are all nicely separated out. We'll guard them with the same "#if defined" that the header has and add a little stub function if OF_GPIO is not defined.

Compared to its predecessors, the PX30 VOP has a different register layout for enabling per-pixel alpha. Instead of src_alpha_ctl and dst_alpha_ctl, there is a single alpha control register. This register takes some fields from src_alpha_ctl, but with a different layout. Add support for the required fields to the PX30 VOP window descriptions, which makes per-pixel-alpha formats behave correctly. Signed-off-by:

During the initial MST probing an MST port's I2C device will be registered using the kdev of the DRM device as a parent. Later after MST Connection Status Notifications this I2C device will be re-registered with the kdev of the port's connector. This will also move inconsistently the I2C device's sysfs entry from the DRM device's sysfs dir to the connector's dir. Fix the above by keeping the DRM kdev as the parent of the I2C device. Ideally the connector's kdev would be used as a parent, similarly to non-MST connectors, however that needs some more refactoring to ensure the connector's kdev is already available early enough. So keep the existing (initial) behavior for now. Cc: <stable@vger.kernel.org> Signed-off-by:

The WARN below triggers during the removal of an MST port. The problem is that the parent device's (the connector's kdev) sysfs directory is removed recursively when the connector is unregistered (even though the I2C device holds a reference on the parent device). To fix this set first the Peer Device Type to none which will remove the I2C device. Note that atm, inconsistently, the parent of the I2C device is initially set to the DRM kdev and after a Connection Status Notification the parent may be reset to be the connector's kdev. This problem is addressed by the next patch.

Some TypeC -> native DP adapters, at least the Club 3D CAC-1557 adapter, incorrectly filter out HPD short pulses with a duration less than ~540 usec, leading to MST probe failures. According to the DP Standard 2.0 section 5.1.4: - DP sinks should generate short pulses in the 500 usec -> 1 msec range - DP sources should detect short pulses in the 250 usec -> 2 msec range According to the DP Alt Mode on TypeC Standard section 3.9.2, adapters should detect and forward short pulses according to how sources should detect them as specified in the DP Standard (250 usec -> 2 msec). Based on the above filtering out short pulses with a duration less than 540 usec is incorrect. To make such adapters work add support for a driver polling on MST inerrupt flags, and wire this up in the i915 driver. The sink can clear an interrupt it raised after 110 msec if the source doesn't respond, so use a 50 msec poll period to avoid missing an interrupt. Polling of the MST interrupt flags is explicitly allowed by the DP Standard. This fixes MST probe failures I saw using this adapter and a DELL U2515H monitor. v2: - Fix the wait event timeout for the no-poll case. v3 (Ville): - Fix the short pulse duration limits in the commit log prescribed by the DP Standard. - Add code comment explaining why/how polling is used. - Factor out a helper to schedule the port's hpd irq handler and move it to the rest of hotplug handlers. - Document the new MST callback. - s/update_hpd_irq_state/poll_hpd_irq/ Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by:
