From 6f07b72adaeddc9a90306ab4f2237b90967fd3ce Mon Sep 17 00:00:00 2001 From: Gery Kahn Date: Mon, 18 Jul 2011 14:21:49 +0300 Subject: [PATCH] wl12xx: fixes for hw_pg_ver and chip id reporting Fix the value of PG version for 128x at sysfs, remove write permissions from PG version (hw_pg_ver) in sysfs and add remove files (hw_pg_ver,bt_coex_state) from sysfs while freeing hardware. New macro names for register Fuse_data_2_1 depend on architecture. Propagate chip id through wiphy in PLT mode which still not work of a bug in ethtool.
