Subject: [PATCH 2/4] rt2800: enable TX_PIN_CFG_RFRX_EN only for MT7620
Date: Wed, 10 Oct 2018 17:46:18 +0200	[thread overview]
Message-ID: <1539186380-31949-3-git-send-email-sgruszka@redhat.com> (raw)
In-Reply-To: <1539186380-31949-1-git-send-email-sgruszka@redhat.com>

The TX_PIN_CFG_RFRX_EN bit was not set on other devices than MT7620,
restore old behavaviour since setting this bit maight not be
correct for older devices.
