There is little point in using %ps to print a value known to be NULL. On the other hand it makes sense to print the callback symbol in the 'invalid IRQ' message. Correct those two error messages to make more sense. Fixes: 68931991 ("drm/msm/dpu: stop using raw IRQ indices in the kernel output") Signed-off-by:

DP controller can be setup to operate in either SDP update flush mode or peripheral flush mode based on the DP controller hardware version. Starting in DP v1.2, the hardware documents require the use of peripheral flush mode for SDP packets such as PPS OR VSC SDP packets. In-line with this guidance, lets program the DP controller to use peripheral flush mode starting DP v1.2 Changes in v4: - Clear up that DP_MAINLINK_CTRL_FLUSH_MODE register requires the use of bits [24:23] - Modify macros DP_MAINLINK_FLUSH_MODE_UPDATE_SDP and DP_MAINLINK_FLUSH_MODE_SDP_PERIPH_UPDATE to explicitly set their values in the bits of DP_MAINLINK_CTRL_FLUSH_MODE_MASK Changes in v3: - Clear up that the DP_MAINLINK_FLUSH_MODE_SDE_PERIPH_UPDATE macro is setting bits [24:23] to a value of 3 Changes in v2: - Use the original dp_catalog_hw_revision() function to correctly check the DP HW version Signed-off-by:

If an eDP panel is not powered on then any attempts to talk to it over the DP AUX channel will timeout. Unfortunately these attempts may be quite slow. Userspace can initiate these attempts either via a /dev/drm_dp_auxN device or via the created i2c device. Making the DP AUX drivers timeout faster is a difficult proposition. In theory we could just poll the panel's HPD line in the AUX transfer function and immediately return an error there. However, this is easier said than done. For one thing, there's no hard requirement to hook the HPD line up for eDP panels and it's OK to just delay a fixed amount. For another thing, the HPD line may not be fast to probe. On parade-ps8640 we need to wait for the bridge chip's firmware to boot before we can get the HPD line and this is a slow process. The fact that the transfers are taking so long to timeout is causing real problems. The open source fwupd daemon sometimes scans DP busses looking for devices whose firmware need updating. If it happens to scan while a panel is turned off this scan can take a long time. The fwupd daemon could try to be smarter and only scan when eDP panels are turned on, but we can also improve the behavior in the kernel. Let's let eDP panels drivers specify that a panel is turned off and then modify the common AUX transfer code not to attempt a transfer in this case. Tested-by:

Additionally in drm_mode_config_helper_suspend() and drm_mode_config_helper_resume() calls, that re the callers of these functions, avoid invoking them if polling is not initialized. For drivers like hyperv-drm, that do not initialize connector polling, if suspend is called without this check, it leads to suspend failure with following stack [ 770.719392] Freezing remaining freezable tasks ...

The drm_num_crtcs() helper determines the number of CRTCs by iterating over the list of CRTCs that have been registered with the mode config. However, we already keep track of that number in the mode config's num_crtcs field, so we can simply retrieve the value from that and remove the extra helper function. Signed-off-by:
