After going through all the trouble of splitting out parts from drm_crtc.[hc] and then properly documenting each I've entirely forgotten to show the same TLC for CRTCs themselves! Let's make amends asap. v2: Review from Eric. Reviewed-by:

struct drm_dp_mst_topology_mgr currently stores a pointer to struct dev. Changing this to instead hold a pointer to drm_device is more useful as it gives access to DRM structures. This also makes it consistent with other DRM structures like drm_crtc, drm_connector etc. Signed-off-by:

This avoids using the deprecated drm_get_pci_dev() and load() hook interfaces in the qxl driver. The only tricky part is to ensure TTM debugfs initialization happens after the debugfs root node is created, which is done by moving that code into the debufs_init() hook. Tested on qemu with igt and running a WM on top of X. Changes since v1: - Drop verification for primary minor in qxl_debugsfs_init. Changes since V2: - Put new header together with other debugfs headers. Signed-off-by:

I've found that by just turning the chip on and off via the POWER_DOWN register, I end up getting i2c_transfer errors on HiKey. Investigating further, it turns out that some of the register state in hardware is getting lost, as the device registers are reset when the chip is powered down. Thus this patch simply re-writes the i2c address to the ADV7511_REG_EDID_I2C_ADDR register to ensure its properly set before we try to read the EDID data.

Thus this patch changes the EDID probing logic so that we re-use the __adv7511_power_on/off() calls instead of duplciating logic. This does change behavior slightly as it adds the HPD signal pulse to the EDID probe path, but Archit has had a patch to add HPD signal pulse to the EDID probe path before, so this should address the cases where that helped. Another difference is that regcache_mark_dirty() is also called in the power off path once EDID is probed.

On some adv7511 implementations, we can get some spurious disconnect signals which can cause monitor probing to fail. This patch enables HPD (hot plug detect) interrupt support which allows the monitor to be properly re-initialized when the spurious disconnect signal goes away. This also enables proper hotplug support.

In chasing down a previous issue with EDID probing from calling drm_helper_hpd_irq_event() from irq context, Laurent noticed that the DRM documentation suggests that drm_kms_helper_hotplug_event() should be used instead. Thus this patch replaces drm_helper_hpd_irq_event() with drm_kms_helper_hotplug_event(), which requires we update the connector.status entry and only call _hotplug_event() when the status changes.

I was recently seeing issues with EDID probing, where the logic to wait for the EDID read bit to be set by the IRQ wasn't happening and the code would time out and fail. Digging deeper, I found this was due to the fact that IRQs were disabled as we were running in IRQ context from the HPD signal. Thus this patch changes the logic to handle the HPD signal via a work_struct so we can be out of irq context. With this patch, the EDID probing on hotplug does not time out.

The PHY reset signal is controlled by bit PHYRSTZ in the MC_PHYRSTZ register. The signal is active low on Gen1 PHYs and active high on Gen2 PHYs. The driver toggles the signal high then low, which is correct for all currently supported platforms, but the register values macros are incorrectly named. Replace them with a single macro named after the bit, and add a comment to the source code to explain the behaviour. The driver's behaviour isn't changed by this rename, the code will still need to be fixed to support Gen1 PHYs. Signed-off-by:

The DWC HDMI TX can be recognized by the two product identification registers. If the registers don't read as expect the IP will be very different than what the driver has been designed for, or will be misconfigured in a way that makes it non-operational (invalid memory address, incorrect clocks, ...). We should reject this situation with an error. While this isn't critical for proper operation with supported IPs at the moment, the driver will soon gain automatic device-specific handling based on runtime device identification. This change makes it easier to implement that without having to default to a random guess in case the device can't be identified. While at it print a readable version number in the device identification message instead of raw register values. Signed-off-by:
