From 672825cd2823a0cee4687ce80fef5b702ff3caa3 Mon Sep 17 00:00:00 2001 From: Jack Chen Date: Wed, 7 Dec 2022 15:50:59 -0500 Subject: i3c: export SETDASA method Because not all I3C drivers have the hot-join feature ready, and especially not all I3C devices support hot-join feature, exporting SETDASA method could be useful. With this function, the I3C controller could perform a DAA to I3C devices when users decide to turn these I3C devices off and on again during run-time. Tested: This change has been tested with turnning off an I3C device and turning on it again during run-time. The device driver calls SETDASA method to perform DAA to the device. And communication between I3C controller and device is set up again correctly.
