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.

Instead of coding the soft PHY reset function multiple times in marvell.c,
lets call the common phy_reset() function from phy.c.

Move this driver over to use driver model. This involves rearranging the

At present we have code in arch/arm and code in drivers/video. Move it all
into drivers/video since it is a display driver and our current approach is
to put all driver code in drivers/.

Adjust the driver to use driver model. The SOR becomes a bridge device. We

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.

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.

emac module of the davinci platform supports only 8 tx and 8
rx channels (total 16). emac driver for davinci platform,
however, while doing initialization of the dma descriptor
head pointers, wrongly initializes the 16 head pointers
(instead of 8) for tx dma and 16 head pointers (insted of 8)
for rx dma, which is wrong. The result is, that this register
initilization spills over the other registers which was not
intended and is undesirable. This patch fixes this problem.
