Subject: [PATCH 02/12] brcmsmac: change pa_gain for bcm4313 iPA
Date: Tue, 20 Aug 2013 16:00:36 +0200 [thread overview]
Message-ID: <1377007246-9957-3-git-send-email-arend@broadcom.com> (raw)
In-Reply-To: <1377007246-9957-1-git-send-email-arend@broadcom.com>
The function wlc_lcnphy_load_tx_gain_table() has a target PA
gain specified for the iPA variant of the bcm4313. This gain
value is reduced to avoid PA distortion. The if-statement is
removed because it was rather redundant in the first place.
Please note that this patch does not provide full iPA support.
