Subject: [PATCH v3 11/18] phy: cadence-torrent: register resets even if the phy is already configured
Date: Thu, 15 Feb 2024 16:17:56 +0100 [thread overview]
Message-ID: <20240102-j7200-pcie-s2r-v3-11-5c2e4a3fac1f@bootlin.com> (raw)
In-Reply-To: <20240102-j7200-pcie-s2r-v3-0-5c2e4a3fac1f@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.
