From 19939860dcae5a3b2e11318eb7d65b4db2e55e2b Mon Sep 17 00:00:00 2001 From: anish kumar Date: Fri, 17 Aug 2012 09:57:22 -0700 Subject: extcon: adc_jack: adc-jack driver to support 3.5 pi or simliar devices External connector devices that decides connection information based on ADC values may use adc-jack device driver. The user simply needs to provide a table of adc range and connection states. Then, extcon framework will automatically notify others. Changes in V1: added Lars-Peter Clausen suggested changes: Using macros to get rid of boiler plate code such as devm_kzalloc and module_platform_driver.Other changes suggested are related to coding guidelines. Changes in V2: Removed some unnecessary checks and changed the way we are un-regitering extcon and freeing the irq while removing. Changes in V3: Renamed the files to comply with extcon naming. Changes in V4: Added the cancel_work_sync during removing of driver. Changes in V5: Added the dependency of IIO in Kconfig. Changes in V6: Some nitpicks related to naming. Changes in this version: V6 patch version patch broke the build: ERROR: "extcon_cable_name" [drivers/extcon/extcon-adc-jack.ko] undefined! Fixed it in this version.
