But from chipsets like sdm660, DSI_CMD_OFFSET and DSI_CMD_LENGTH register has become double buffered and since timing db property was enabled as part of dynamic fps update, DSI commands transfer for backlight update, panel health check or panel off might fail if there is no control flush. So disable DSI timing db property once dynamic fps update sequence is complete. Change-Id: I5158a36c9eea8f257ec81bab2f260e072fc22f29 Signed-off-by: Sandeep Panda <spanda@codeaurora.org>

This change makes sure that any time that the MDSS GDSC regulator is enabled or when the MDSS GDSC regulator is disabled but the Display is still active but in Idle Screen, Display sets the flag to ensure that the MMSS GDSC regulator is not disabled by the RPM, flag is released once our MDSS regulator is disabled for Suspend. Also, re-arrange the sequence to make sure the change of the flag happens after we disabled the MDSS GDSC regulator, so we prevent that by any reason the MDSS GDSC could go off before the MMSS GDSC regulator.

These VICs can be reused for a subsequent connection for different resolutions. In the current implementation of the Display Port (DP) driver, a resolution change is detected whenever a new VIC is used. However, when switching between two non-standard resolutions spanning connections to two different sinks, it is possible to have the same VIC assigned for the two resolutions. This can result in abnormal behavior. Fix this by resetting the video identification code and panel information to reset value every time we get an HPD for disconnect.

HDCP may be turned off by other thread abruptly depending on the use-case. Do not poll hardware in case HDCP has been turned off. Also, wait for authenticating thread to finish in hdcp off thread to avoid any race condition.
