The padconf register WAKEUP_EN is now handled in a generic way using
Linux wakeirqs where pinctrl-single toggles the WAKEUP_EN bit when
a wakeirq is enabled or disabled.
At least omap5 gets confused if the WAKEUP_EN bit is set and the pin
is not claimed as a wakeirq. The end result is that wakeirqs don't
work properly as there is nothing handling the wakeirq.
So let's just remove the WAKEUP_EN usage from dts files.

Like the Nokia N900, the N950 has leds to show
the state of sys_clkreq and sys_off_mode pins.
A detailed description for the LEDs and
OMAP's sleep states can be found in Tony's

This adds an idle pinctrl state, which will be used
by the driver to avoid incoming data during clock
rate changes or data flushing.

Add support for the wl1271 wlan chip. As far as I can see N9 uses the
same chip with the same enable and irq gpio, but they use the mmc
interface instead of the spi interface.

Use the pinmux IOPAD macro to define the register absolute physical
address instead of the offset from the padconf base address. This
makes the DTS easier to read since matches the addresses listed in
the Technical Reference Manual.

The GPMC binding is obviously very confusing as the values
are all over the place. People seem to confuse the GPMC partition
size for the chip select, and the device IO size within the GPMC
partition easily.
The ranges entry contains the GPMC partition size. And the
reg entry contains the size of the IO registers of the
device connected to the GPMC.
Let's fix the issue according to the following table:
Device GPMC partition size Device IO size
connected in the ranges entry in the reg entry
NAND 0x01000000 (16MB) 4
16550 0x01000000 (16MB) 8
smc91x 0x01000000 (16MB) 0xf
smc911x 0x01000000 (16MB) 0xff
OneNAND 0x01000000 (16MB) 0x20000 (128KB)
16MB NOR 0x01000000 (16MB) 0x01000000 (16MB)
32MB NOR 0x02000000 (32MB) 0x02000000 (32MB)
64MB NOR 0x04000000 (64MB) 0x04000000 (64MB)
128MB NOR 0x08000000 (128MB) 0x08000000 (128MB)
256MB NOR 0x10000000 (256MB) 0x10000000 (256MB)
Let's also add comments to the fixed entries while at it.
