2017-02-02drm/bridge/sii8620: set gen2 write burst before sending MSC commandAndrzej Hajda
Write burst should be enabled for MHL_INT_RC_FEAT_REQ and disabled for other commands. The patch moves functions up and adds delay setting for MHL3 burst mode.

2017-02-02drm/bridge/sii8620: abstract out sink detection codeAndrzej Hajda
MHL1 and MHL3 have different initialization paths. To make both protocols happy sink detection is put into continuation after link mode enablement.

2017-02-02drm/bridge/sii8620: fix MSC message removalAndrzej Hajda
Messages queue can be cleaned up by message callbacks, to avoid repeated removal of current message it should be removed from the queue before calling these callbacks.

2017-02-02drm/bridge/sii8620: respond to feature requestsAndrzej Hajda
MHL3 protocol requires device to respond to feature request from peer. This minimal answer fulfills the requirement and allows to continue negotiation.

2017-02-02drm/bridge/sii8620: initial support for eCBUS-S modeAndrzej Hajda
The Single-ended eCBUS Mode (eCBUS-S) mode provides 60 Mb/s full-duplex bidirectional traffic for three channels: - CBUS data (CBUS1 channel), - High-bandwidth MHL data (eMSC channel), - tunneling data (T-CBUS channel). It is required to fully support MHL3 dongles.

2017-02-02drm/bridge/sii8620: add continuations to messagesAndrzej Hajda
Due to asynchronous nature of MHL flow of execution is dispersed. Logical continuation of some actions happens after response of peer, i.e in interrupt handler. To simplify coding continuation mechanism has been added - it is now possible to provide continuation callback, which will be called after peer responds to given action.

2016-10-26drm/bridge: add Silicon Image SiI8620 driverAndrzej Hajda
SiI8620 transmitter converts eTMDS/HDMI signal to MHL 3.0. It is controlled via I2C bus. Its interaction with other devices in video pipeline is performed mainly on HW level. The only interaction it does on device driver level is filtering-out unsupported video modes, it exposes drm_bridge interface to perform this operation.
