Subject: [PATCH 4/4] ath9k_hw: fix analog shift register writes on AR9003
Date: Fri, 30 Jul 2010 21:02:12 +0200	[thread overview]
Message-ID: <1280516532-42721-4-git-send-email-nbd@openwrt.org> (raw)
In-Reply-To: <1280516532-42721-3-git-send-email-nbd@openwrt.org>

Writes to the analog shift registers, which are issues by the initval
programming function, require a 100 usec delay (similar to AR9002,
but in a different register range).
