| | | | | | | | | When setting the rates for the DSI byte clock, pixel clock and the escape clock, use the computed values based on panel parameters instead of hardcoded values. Change-Id: Ief4d639d2d67b99439784eeb68cae924619cbaf1 Signed-off-by: Aravind Venkateswaran <aravindh@codeaurora.org>

| | | | | | | | | | | | | The pan_display path to send the frame update is not setup to support continuous splash screen feature. Continuous splash screen is broken if the first update cames via a pan_display. We need to setup the mixer for the continuous splash screen feature. This has to be delayed till the split display setup has been completed. Change-Id: I2f0f268c1988f58c02cbdba7bc48b53bf999eea5 Signed-off-by: Siddhartha Agrawal <agrawals@codeaurora.org>

| | | | | | | | | | Implement pm suspend logic for each virtual framebuffer device to ensure framebuffer devices are suspended before MDP (which is parent of these) and resumed after. Once this happens MDP can ensure that clocks and regulators are completely off or on depending on suspend state.

| | | | | | | | | | | | | | Enabling for MTP, CDP and FLUID devices. The continuous splash flag is set in the platform dtsi which will keep the MDSS and DSI settings intact till the first frame update. Since the MDSS related clocks are enabled in the lk, we still vote for the clocks in our probe to carry them forward. The bandwidth request is made for the same reason as well.

| | | | | | | | | | | | | | | | By default, HDMI driver adds entries for all the formats that it supports into an internal table. However, when MHL Tx is present, the max format supported should be limited based on the maximum bandwidth supported by the MHL Tx. We implement a handshake between HDMI and MHL drivers to exchange callback function which returns the status of HDMI's TMDS lines that is used by MHL driver before sending RAP messages.

Needed by destination side post processing features in particular since their updates are made independently of display updates and effect objective display quality.
