12afc0cf81 ARM: dts: Drop pointless status changing for am3 musb
The default is enabled, and there should be no need to reconfigure
the status for SoC internal devices in the board specific files.

Only the USB PHY used needs to be configured in the board specific
files.

572cf7d7b0 ARM: dts: Improve omap l4per idling with wlcore edge sensitive interrupt
The wl1835mod.pdf data sheet says this pretty clearly for WL_IRQ line:

"WLAN SDIO out-of-band interrupt line. Set to rising edge (active high)
by default."

And it seems this interrupt can be optionally configured to use falling
edge too since commit bd763482c8 ("wl18xx: wlan_irq: support platform
dependent interrupt types").

On omap4, if the wlcore interrupt is configured as level instead of edge,
L4PER will stop doing hardware based idling after ifconfig wlan0 down is
done and the WL_EN line is pulled down.

The symptoms show up with L4PER status registers no longer showing the
IDLEST bits as 2 but as 0 for all the active GPIO banks and for
L4PER_CLKCTRL. Also the l4per_pwrdm RET count stops increasing in
the /sys/kernel/debug/pm_debug/count.

While there is also probably a GPIO related issue that needs to be
still fixed, this change gets us to the point where we can have L4PER
idling.

I'm guessing wlcore was at some point configured to use level interrupts
because of edge handling issues in gpio-omap. However, with the recent
fixes to gpio-omap the edge interrupts seem to be working just fine.

Let's change it for all omap boards with wlcore interrupt set as level.

GPIO_ACTIVE_LOW was being used to specify an interrupt, use
IRQ_TYPE_EDGE_RISING instead. This improves DT readability.

05e7d622f1 ARM: dts: omap: Add generic compatible string for I2C EEPROM
The at24 driver allows to register I2C EEPROM chips using different vendor
and devices, but the I2C subsystem does not take the vendor into account
when matching using the I2C table since it only has device entries.

But when matching using an OF table, both the vendor and device has to be
taken into account so the driver defines only a set of compatible strings
using the "atmel" vendor as a generic fallback for compatible I2C devices.

So add this generic fallback to the device node compatible string to make
the device to match the driver using the OF device ID table.

ce2899428e ARM: dts: am335x-baltos: disable EEE for Atheros 8035 PHY
Though cpsw doesn't support EEE feature, Atheros 8035 provides
automatic EEE support that is enabled by default. This causes
occasional link drops when link partner also announces EEE support.
These link drops occur on both 100Mbit/s and 1000Mbit/s speeds.
So disable EEE advertising completely.
