I don't know how to test newly added features, but at least the patches don't seem to break existing users, so on rk3288 and rk3328 Tested-by: Heiko Stuebner _______________________________________________ linux-amlogic mailing list linux-amlogic@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-amlogic
