From e904cf6fe23022cde4e0ea9d41601411a315a3dc Mon Sep 17 00:00:00 2001 From: Oleksij Rempel Date: Sun, 6 Sep 2015 13:09:01 +0200 Subject: ath9k_htc: introduce support for different fw versions MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Current kernel support only one fw name with theoretically only one fw version located in “firmware/htc_[9271|7010].fw”. Which is ok so far we have only one fw version (1.3). After we realised new fw 1.4, we faced compatibility problem which was decided to solve by firmware name and location: - new firmware is located now in firmware/ath9k_htc/htc_[9271|7010]-1.4.0.fw - old version 1.3 should be on old place, so old kernel have no issues with it. - new kernels including this patch should be able to try different supported (min..max) fw version. - new kernel should be able to support old fw location too. At least for now. At same time this patch will add new module option which should allow user to play with development fw version without replacing stable one. If user will set “ath9k_htc use_dev_fw=1” module will try to find firmware/ath9k_htc/htc_[9271|7010]-1.dev.0.fw first and if it fails, use stable version: for example...1.4.0.fw.
