From 2a8ff6112df887f36b36a051dbe3d45c386d60ea Mon Sep 17 00:00:00 2001 From: Amitkumar Karwar Date: Tue, 24 Apr 2012 16:31:40 -0700 Subject: [PATCH] Bluetooth: btmrvl: configure default host sleep parameters Currently debugfs commands "hscfgcmd" and "gpiogap" are provided for host sleep configuration. But if user doesn't configure host sleep parameters using these commands, host sleep activation is failed during suspend (support for suspend and resume handlers is added in next patch). Default host sleep configuration is done during driver initialisation in this patch.
