2019-08-23phy: mvebu-a3700-comphy: Inform users if their firmware is too oldMiquel Raynal1-1/+8
PHY configuration has been implemented in the firmware and accessed through SMC calls. In the past, it worked magically if the bootloader was correctly doing the initializations. With up-to-date bindings, the kernel will need a recent firmware in order to do the initializations himself (we assume people must update their firmware along with their kernel). People might not understand why IPs that were working correctly before stopped to be probed suddendly. In this case, let's advise the users to update their firmware with a visual warning.

2019-08-23phy: marvell: phy-mvebu-a3700-comphy: Add of_node_put() before returnNishka Dasgupta1-2/+6
Each iteration of for_each_available_child_of_node puts the previous node, but in the case of a return from the middle of the loop, there is no put, thus causing a memory leak. Hence add an of_node_put before the return in two places. Issue found with Coccinelle. Signed-off-by: Nishka Dasgupta <nishkadg.linux@gmail.com> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>
2019-02-07phy: add A3700 COMPHY supportMiquel Raynal1-0/+318
Add a driver to support COMPHY, a hardware block providing shared serdes PHYs on Marvell Armada 3700. This driver uses SMC calls and rely on having an up-to-date firmware. SATA, PCie and USB3 host mode have been tested successfully with an ESPRESSObin. (HS)SGMII mode cannot be tested with this platform. Evan worked on the original driver structure and Grzegorz on the SMC calls rework. The structure of this driver has been copied from Antoine Tenart work on CP110 COMPHY driver.
