From 1de00dae8036dfee44ebea2c38f942fb6072e0b7 Mon Sep 17 00:00:00 2001 From: David Brownell Date: Thu, 2 Apr 2009 10:16:11 -0700 Subject: musb: make initial HNP roleswitch work (v2) Minor HNP bugfixes, so the initial role switch works: - A-Device: * disconnect-during-suspend enters A_PERIPHERAL state * kill OTG timer after reset as A_PERIPHERAL ... * ... and also pass that reset to the gadget * once HNP succeeds, clear the "ignore_disconnect" flag * from A_PERIPHERAL, disconnect transitions to A_WAIT_BCON - B-Device: * kill OTG timer on entry to B_HOST state (HNP succeeded) * once HNP succeeds, clear "ignore_disconnect" flag * kick the root hub only _after_ the state is adjusted Other state transitions are left alone. Notably, exit paths from the "roles have switched" state ... A_PERIPHERAL handling of that stays seriously broken.
