Subject: [Resend] [PATCH 0/9] ideapad: using EC command to control rf/camera power
Date: Fri, 1 Oct 2010 15:37:40 +0800 [thread overview]
Message-ID: <1285918660-12802-1-git-send-email-ike.pan@canonical.com> (raw)
These patches are made against current mainline kernel and also available at
git://kernel.ubuntu.com/ikepanhc/ideapad-laptop.git for-upstream
Once the rfkill of a laptop is set to block, it is no way to unblock with Linux
without driver. Thanks for David Woodhouse wrote the first driver solving this.
But the \_SB_.GECN and \_SB_.DECN are only available on Lenovo ideapad S10-3.
Using EC command to control rf/camera power is better because I believe every
ideapads which has VPC2004 device in its DSDT has this common method.
This driver is tested on Lenovo ideapad B550 and ideapad S10-3 and also tested
by Mario 'BitKoenig' Holbe on Lenovo ideapad S12-VIA.
Changes after last posted:
* Add schedule() to yield processor when waiting EC.
* Using time_before() to check timeout.
* Maximun waiting for EC execution increasing to 100ms in case that we have a
slow EC.
* Add parameter: no_bt_rfkill for not setup bluetooth rfkill.
Next step for this driver:
* Hotkey enablement.
Ike Panhc (9):
ideapad: add ACPI helpers
ideapad: check VPC bit before sync rfkill hw status
ideapad: make sure we bind on the correct device
ideapad: use return value of _CFG to tell if device exist or not
ideapad: use EC command to control camera
ideapad: rewrite the hw rfkill notify
ideapad: rewrite the sw rfkill set
ideapad: Change the driver name to ideapad-laptop
ideapad: Add param: no_bt_rfkill
