From: amartin@nvidia.com Date: Tue, 20 Dec 2011 14:56:16 +0000 (+0000) Subject: USB: move keyboard polling into kbd driver X-Git-Tag: v2012.04-rc1~90 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=f9636e8d38abde096fbb32fee5a36bbdb02b7cae;p=u-boot USB: move keyboard polling into kbd driver This moves keyboard polling logic from USB HCD drivers into USB keyboard driver. Remove usb_event_poll() as keyboard polling was the only user of this API. With this patch USB keyboard works with EHCI controllers again. Tested on a tegra2 seaboard.
