2018-06-19net: ravb: Support reset GPIO both in mac and phy nodeMarek Vasut
The recent DTs have the PHY reset GPIO in the PHY node rather than the ethernet MAC node, support extracting the PHY reset GPIO info from both the PHY node and ethernet MAC node.

2018-06-19net: ravb: Filter out supported PHY featuresMarek Vasut
The RAVB only supports 100Full and 1000Full operation, it does not support 10Full or any Half-duplex modes. The PHY could still advertise those features though, so filter out the PHY features accordingly.

2018-06-19net: ravb: Do not shut down clock in start callbackMarek Vasut
Do not stop the clock in the start callback in case of failure, keep them running to also keep the PHY running. The failure could be ie. PHY failing to negotiate link and if the clock get shut down, another attempt at bringing the link up would fail. The clock right now are started in probe function and stopped in remove function, which is the correct behavior.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

2018-02-16net: ravb: Initialize PHY in probe() onceMarek Vasut
Reset and initialize the PHY once in the probe() function rather than doing it over and over again is start() function. This requires us to keep the clock enabled while the driver is in use. This significantly reduces the time between transfers as the PHY doesn't have to restart autonegotiation between transfers, which takes forever.

2017-11-30net: ravb: Fix reset GPIO handlingMarek Vasut
Fix handling of the reset GPIO. Drop the _nodev() suffix from the gpio_request_by_name() call as there is now a proper DM capable GPIO driver. Also check if the GPIO is valid before freeing it in remove path, otherwise U-Boot will crash.
