Subject: [PATCH 44/78] wlcore/wl12xx: add plt_init op and move the code to wl12xx
Date: Thu, 10 May 2012 12:13:49 +0300	[thread overview]
Message-ID: <1336641263-5761-45-git-send-email-arik@wizery.com> (raw)
In-Reply-To: <1336641263-5761-1-git-send-email-arik@wizery.com>

From: Luciano Coelho <coelho@ti.com>

PLT mode needs to be initialized differently for each chip.  This
patch adds an operation to init PLT and moves the existing PLT
initialization into the wl12xx driver.
