From ae7b4d4bb5d6769ba64cdfca9d8e77dd4e671f6d Mon Sep 17 00:00:00 2001 From: Jarod Wilson Date: Mon, 9 May 2011 11:48:33 -0300 Subject: [media] ite-cir: make IR receive work after resume MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Just recently acquired an Asus Eee Box PC with an onboard IR receiver driven by ite-cir (ITE8713 sub-variant). Works out of the box with the ite-cir driver in 2.6.39, but stops working after a suspend/resume cycle. Its fixed by simply reinitializing registers after resume, similar to what's done in the nuvoton-cir driver. I've not tested with any other ITE variant, but code inspection suggests this should be safe on all variants.
