falco: add rtd2132 settings to device tree
Now that the rtd2132 device has the full settings the panel timings need to be implemented. Sadly, the Tx timings in the rtd2132 aren't 1:1 with the panel's Tx timings. Below is the table equivalent: RTD2132 | Falco Panel --------+------------ T1 | T2 --------+------------ T2 | T8+T10+T12 --------+------------ T3 | T14 --------+------------ T4 | T15 --------+------------ T5 | T9+T11+T13 --------+------------ T6 | T3 --------+------------ T7 | T4 --------+------------ Change-Id: I10a3ad475d6b9485a707eb49e31afd197fc8d24d Signed-off-by: Aaron Durbin <adurbin@chromium.org> Reviewed-on: https://gerrit.chromium.org/gerrit/65858 Reviewed-by: Stefan Reinauer <reinauer@google.com> Reviewed-on: http://review.coreboot.org/4472 Tested-by: build bot (Jenkins) Reviewed-by: Patrick Georgi <patrick@georgi-clan.de>
