| * | | | | | | | | msm: mdss: Fix scaler enable flag settingAbhijit Kulkarni2016-12-12

For qseed2 scaler the enable flag should be set to true if this structure is populated from user space driver.

Hence removing the synchronization mechanism which can cause performance issues.

Panel porches might need update before pixel clock tuning based on standard framerate mapping.

In another thread we read the panel status and DSI ack returns error. In the error condition we are trying to read some DSI registers even when the clocks are turned off.

Returning EAGAIN might make the verification tests to continuously query the sysfs nodes, or block it. Returning EPERM will fail the query, which is expected.

This also fixes certain devices which would not respond unless there was a status object included in the request. Initialize this to 0x1 to indicate that the DFP_D is connected. - Don't send Enter Mode if the discovered mode doesn't support UFP_D. - Don't send Configure if the Status response doesn't support UFP_D.
