The PHY ownership release->AUX PW disable steps during a modeset disable->PHY disconnect sequence can hang the system if the PHY disconnect happens after disabling the PHY's PLL. The spec doesn't require a specific order for these two steps, so this issue is still being root caused by HW/FW teams. Until that is found, let's make sure the disconnect happens before the PLL is disabled, and do this on all platforms for consistency. v2: Add a TODO comment to remove the w/a once the issue is root caused/fixed.

After the previous patch the driver holds a power domain blocking TC-cold whenever the port is locked, so we can remove the extra blocking around the lock/unlock sequence. Cc: José Roberto de Souza <jose.souza@intel.com> Signed-off-by:

So far TC-cold was blocked only for the duration of TypeC mode resets. The DP-alt and legacy modes require TC-cold to be blocked also whenever the port is in use (AUX transfers, enable modeset), and this was ensured by the held PHY ownership flag. On ADL-P this doesn't work, since the PHY ownership flag is in a register backed by the PW#2 power well. Whenever this power well is disabled the ownership flag is cleared by the HW under the driver. The only way to cleanly release and re-acquire the PHY ownership flag and also allow for power saving (by disabling the display power wells and reaching DC5/6 states) is to hold the TC-cold blocking power domains while the PHY is connected and disconnect/reconnect the PHY on-demand around AUX transfers and modeset enable/disables. Let's do that, disconnecting a PHY with a 1 sec delay after it becomes idle. For consistency do this on all platforms and TypeC modes. v2: Add tc_mode!=disconnected and phy_is_owned asserts to __intel_tc_port_lock().

While a TypeC port mode is locked a DISPLAY_CORE power domain reference is held, which implies a runtime PM ref. By removing the ICL !legacy port special casing, a TC_COLD_OFF power domain reference will be taken for such ports, which also translates to a runtime PM ref on that platform. A follow-up change will stop holding the DISPLAY_CORE power domain while the port is locked. Cc: José Roberto de Souza <jose.souza@intel.com> Signed-off-by:

For the ADL-P TBT mode the spec doesn't require blocking TC-cold by using the legacy AUX power domain. To avoid the timeouts that this would cause during PHY disconnect/reconnect sequences (which will be more frequent after a follow-up change) use the TC_COLD_OFF power domain in TBT mode on all platforms. On TGL this power domain blocks TC-cold via a PUNIT command, while on other platforms the domain just takes a runtime PM reference. If the HPD live status indicates that the port mode needs to be reset - for instance after switching from TBT to a DP-alt sink - still take the AUX domain, since the IOM firmware handshake requires this. v2: Rebased on v2 of the previous patch.

A follow-up change will select the TC-cold blocking power domain based on the TypeC mode, prepare for that here. Also bring intel_tc_cold_requires_aux_pw() earlier to its logical place for readability. No functional change. v2: Add code comment about IOM reg accesses in TCCOLD.

Imre Deak authored
A follow-up change will start to disconnect/re-connect PHYs around AUX transfers and modeset enable/disables. To prepare for that add a new TypeC PHY disconnected mode, to help tracking the TC-cold blocking power domain status (no power domain in disconnected state, mode dependent power domain in connected state). v2: Move the !disconnected mode and phy-owned asserts in __intel_tc_port_lock() later in the patchset, when the asserts will hold.

A follow-up patch will disconnect/reconnect PHYs around AUX transfers and modeset enable/disables. To prepare for that and make things consistent for all TypeC modes stop connecting the PHY in legacy mode without a sink being connected. This was done before since in legacy mode the PHY is dedicated to display usage, so there was no point in disconnecting it. However after the follow-up changes the TC-cold blocking power domains will be held as long as the PHY is in the connected state, so we'll need to disconnect/re-connect the PHY in all TypeC modes to allow for power saving.

On ADL-P the PHY ready/complete flag is always set even in TBT-alt mode. To avoid taking the PHY ownership and the following spurious "PHY sudden disconnect" messages on this platform when connecting the PHY in TBT mode, check if there is any DP-alt or legacy sink connected before taking the ownership. v2: (Jose) - Fix debug message clarifying that a TBT sink can be connected. - Add comments describing the PHY complete HW flag semantic differences between adl-p and other platforms.

Imre Deak authored
Waiting for the PHY complete flag to clear when releasing the PHY ownership was add in commit ddec3627 ("drm/i915: Wait for TypeC PHY complete flag to clear in safe mode") This isn't required by the spec, the vague idea was to make the handshake with the firmware more robust, without actual evidence for when it would be needed. Checking this again, the flag doesn't clear on ICL until after the PHY's PLL is disabled and the flag is permanently set on ADL-P. To avoid the spurious timeout messages in dmesg, just remove this wait. Cc: José Roberto de Souza <jose.souza@intel.com> Signed-off-by:

On ADL-P the PHY ready (aka status complete on other platforms) flag is always set, besides when a DP-alt, legacy sink is connected also when a TBT sink is connected or nothing is connected. So assume the PHY to be connected when both the TBT live status and PHY ready flags are set. Cc: José Roberto de Souza <jose.souza@intel.com> Signed-off-by:
