2016-02-18net: phy: marvell: Fix problem with phy_reset() clearing BMCRStefan Roese
With commit a058052c [net: phy: do not read configuration register on reset], phy_reset() will clear the BMCR register. Resulting in bit 12 being cleared (A/N enable). This leads to autonegotiation link problems, at least on the Marvell Armada ClearFog board. I suspect that other boards using this driver will be affected as well. At the of m88e1111s_config(), phy_reset() is called. This is not needed for the PHY to load the changed configuration, as phy_reset() is called a few lines before already. So lets call genphy_restart_aneg() here instead to start the AN correctly. Tested on clearfog.

2016-02-16tegra: gpio: Show the GPIO value for outputsSimon Glass
The tegra GPIO controller has two ways of reading the value of a GPIO. It can supply the 'input' value (which is the value read from the pin) and the 'output' value (which is the value being driven from the pin. With a GPIO set to output mode, the 'input' value is always low which is not very useful. This has the unfortunate result that setting a GPIO high still leaves it showing as low in the 'gpio status' command. Adjust the driver to check which direction the GPIO is set to, then read the value from the appropriate register: 'input' for input GPIOs, 'output' for output GPIOs.

2016-02-06video: bcm2835: use bus_to_phys() on FB addressStephen Warren
The FB address is generated by the firmware running on the GPU/VideoCore and is a "bus" address. This address is the other side of an IOMMU from the ARM upon which U-Boot is running. Use bus_to_phys() to convert this to an ARM physical address. Without this, U-Boot seems to work just fine, but once the Linux kernel boots on an RPi2, accessing the FB memory often causes a hard system hang.
