+Subject: [PATCH] phy: marvell: phy-mvebu-a3700-comphy: Remove broken reset
+ support
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Reset support for SATA PHY is somehow broken and after calling it, kernel
+is not able to detect and initialize SATA disk Samsung SSD 850 EMT0 [1].
+
+Reset support was introduced in commit 934337080c6c ("phy: marvell:
+phy-mvebu-a3700-comphy: Add native kernel implementation") as part of
+complete rewrite of this driver. v1 patch series of that commit [2] did
+not contain reset support and was tested that is working fine with
+Ethernet, SATA and USB PHYs without issues too.
+
+So for now remove broken reset support and change implementation of
+power_off callback to power off all functions on specified lane (and not
+only selected function) because during startup kernel does not know which
+function was selected and configured by bootloader. Same logic was used
+also in v1 patch series of that commit.
+
+This change fixes issues with initialization of SATA disk Samsung SSD 850
+and disk is working again, like before mentioned commit.
+
+Once problem with PHY reset callback is solved its functionality could be
+re-introduced. But for now it is unknown why it does not work.
