Support for the USB regulator of AB8500 was removed in
commit 41a06aa738ad ("regulator: ab8500: Remove USB regulator").
However, the configuration was never removed from the device tree.
It does no longer have any effect, remove it from the device tree.

The thermal driver for the DB8500 was never properly converted
to device tree, the node should definitely be activated for
all board variants so move this down into the main SoC
DTSI, and default on.

The physical pins from the SoC are in a sense belonging to the
PHY device (AB8500 USB) rather than the MUSB USB IP block.
The driver definately assumes so: before this change it
complains that it cannot control the pins it is using:
abx5x0-usb ab8500-usb.0: could not get/set default pinstate
After this patch the warning goes away.

This fixes a very annoying regression on the Snowball SD card
that has been around for a while. It turns out that the device
tree does not configure the direction pins properly, nor sets
up the pins for the voltage converter properly at boot. Unless
all things are correctly set up, the feedback clock will not
work, and makes the driver spew messages in the console (but
it works, very slowly):
root@Ux500:/ mount /dev/mmcblk0p2 /mnt/
[ 9.953460] mmci-pl18x 80126000.sdi0_per1: error during DMA transfer!
[ 9.960296] mmcblk0: error -110 sending status command, retrying
[ 9.966461] mmcblk0: error -110 sending status command, retrying
[ 9.972534] mmcblk0: error -110 sending status command, aborting
Fix this by rectifying the device tree to correspond to that of
the Ux500 HREF boards plus the DAT31DIR setting that is unique for
the Snowball, and things start working smoothly. Add in the SDR12
and SDR25 modes which this host can do without any problems.
I don't know if this has ever been correct, sadly. It works after
this patch.

The Snowball gyro and magnetometer DRDY (data ready) lines are used
as interrupt triggers by the IIO subsystem, triggering new data
retrieveal on edges on this signal. Thus assign them as the primary
interrupt in the device tree. The "other interrupt" coming out of
the sensors is for alarms and similar complex events, the DRDY is
for periodic measures, which is what we want.
After this the generic_buffer tool from IIO tools gives a nice
stream of readings after enabling the desired channels in sysfs.

The keyboard driver for GPIO buttons(gpio-keys) checks for one of the
two boolean properties to enable gpio buttons as wakeup source:
1. "wakeup-source" or
2. the legacy "gpio-key,wakeup"
However juno, ste-snowball and emev2-kzm9d dts file have a undetected
"wakeup" property to indictate the wakeup source.
This patch fixes it by making use of "wakeup-source" property.

Ux500 is regressing due to commit
a21763a0b1e5a5ab8310f581886d04beadc16616
"pinctrl: nomadik: activate strict mux mode" which disallows
Nomadik GPIO 5 to be muxed in as a level shifter voltage select
pin, as it is currently described as being used for RX on UART1.
The behaviour is correct, instead the hardware config has been
incorrecly specified: UART1 is indeed unused on HREFv60plus and
Snowball and that is why HREFv60plus can use the pins it would
normally occupy as the voltage select line for the MMC/SD
levelshifter (Snowball uses it for I2C4).
The reason UART1 was anyway enabled on these platforms was
probably to secure the port enumeration to userspace. This
can be solved by using aliases (done in a separate patch) so
we can now deactivate UART1 and let MMC/SD use it properly
on HREFv60plus. We explicitly activate it only for the
older HREFprev60 board.
To complete, we set up the pin configuration for these pins
properly in the sdi0 node.

This enumerates the PL011 serial ports on the Ux500. This is

This moves the MCDE pin control table out of the board file
and into the device tree. Some pins and configs have been
marked as used by sub-devices or slaves to the MCDE, such
as I2C device 0-070 which is the HDMI interface circuit
AV8100, but the pins rather belong to the MCDE SOC block
as they come out of the main ASIC. The touch screen GPIO
is not related to MCDE so this gets deleted and need to
be tied to the respective touch screen (I2C) device
once that device is added instead.

The Ux500 boards are layered like this:
ste-snowball.dts includes ste-href.dtsi that includes
ste-dbx500.dtsi.
The dbx500.dtsi defines the PRCMU SoC regulators so the SoC will
probe and you can use ampersand references where need be.
However the HREF common dtsi and these two boards redefine the
same PRCMU SoC regulators with the very same names and properties
for no reason. This is like filling in the same line three
times instead of drawing it once. Just delete the surplus
references and have the PRCMU regulators defines in the SoC
files ste-dbx500.dtsi, this is enough.

The patch set beginning with commit:
"ARM: ux500: Apply a ste-* prefix onto snowball.dts"
thru commit:
"ARM: ux500: Remove u9540.dts as it's been replaced"
altered the names of the ux500 device tree files but forgot
to:
- Rename the ccu8540-pinctrl.dtsi file
- Update #include statements from files using these
files, so the build broke.
- Update the Makefile for the device trees so the build
broke.
Fix it up so we can build them all again.
