Subject: [PATCH v1 2/2] usb: phy: tegra: Correct definition of B_SESS_VLD_WAKEUP_EN bit
Date: Sun, 13 Jun 2021 17:59:36 +0300	[thread overview]
Message-ID: <20210613145936.9902-2-digetx@gmail.com> (raw)
In-Reply-To: <20210613145936.9902-1-digetx@gmail.com>

The B_SESS_VLD_WAKEUP_EN bit 6 was added by a mistake in a previous
commit. This bit corresponds to B_SESS_END_WAKEUP_EN, which we don't use.
The B_VBUS_VLD_WAKEUP_EN doesn't exist at all and B_SESS_VLD_WAKEUP_EN
needs to be in place of it. We don't utilize B-sensors in the driver,
so it never was a problem, nevertheless let's correct the definition of
the bits.
