Subject: [PATCH v2 09/15] phy: cadence-torrent: register resets even if the phy is already configured
Date: Fri, 26 Jan 2024 15:36:51 +0100	[thread overview]
Message-ID: <20240102-j7200-pcie-s2r-v2-9-8e4f7d228ec2@bootlin.com> (raw)
In-Reply-To: <20240102-j7200-pcie-s2r-v2-0-8e4f7d228ec2@bootlin.com>

Resets are needed during suspend and resume stages.
So they shall be registered during the probe even the phy is already
initialized.

The function cdns_torrent_reset is renamed cdns_torrent_of_get_reset to
make it clear.
