This makes it possible to configure ath9k based devices using devicetree. That makes some out-of-tree "convert devicetree to ath9k_platform_data glue"-code obsolete. Signed-off-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> --- changes in v1 -> v2: - use vendor prefix "qca" instead of "ath" - use of_device_is_available instead of simply checking if "np" is NULL - removed code which read some properties twice drivers/net/wireless/ath/ath9k/init.c | 61 +++++++++++++++++++++++++++++++++++ 1 file changed, 61 insertions(+)
