| * | | | | | | msm: mdss: Add plane_count range check in mdss WFDBenjamin Chan2017-04-28

In addition, write the correct segment address when reading more than two extension blocks.

The transaction retry strategy is as follows: first repeat the transaction using the same PHY AUX settings, and then retry the transaction using updated PHY AUX settings if repeating the transaction has failed.

This enables the extension to support different targets, and combinations of AUX controller settings depending on the use case.

Handle this by checking for a change in downstream sink count and appropriately handling EDID reads. It is also possible that the branch device may not have any local EDID. In such cases, when the downstream sink count is zero, do not read EDID.
