Subject: [PATCH v5 3/5] rt2800: enable TX_PIN_CFG_LNA_PE_ bits per band
Date: Wed, 13 Feb 2019 11:09:14 +0100 [thread overview]
Message-ID: <1550052556-7158-4-git-send-email-sgruszka@redhat.com> (raw)
In-Reply-To: <1550052556-7158-1-git-send-email-sgruszka@redhat.com>
Do not enable TX_PIN_CFG_LNA_PE_A* bits for 2.4GHz band and
vice versa TX_PIN_CFG_LNA_PE_G* bits for 5GHz.
