This change forces a delay for warm reboots to the T12 panel timing as defined in the VBT table for the connected panel. Ver2: removed redundant pr_crit(), commented magic value for pp_div_reg Ver3: moved SYS_RESTART check earlier, new name for pp_div. Ver4: Minor issue changes Ver5: Move registration of reboot notifier to edp_connector_init, Added warning comment to handler about lack of PM notification.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
