adef953bbc ARM: dts: push MMC/SD to board and add comments
This moves the enable-active-high setting from the SoC to the
board for the VMMCQ regulators. It should at least be in the
vicinity of the GPIO line it is defined for.

ac07a4e028 ARM: dts: UX500: name the GPIO lines on HREFv60plus
Using the new line naming mechanism from the GPIO subsystem, name
the GPIO lines on the HREFv60plus board that are connected as
GPIO on this design.

1b1e8e024b ARM: dts: ux500: use the GPIO DT header
Use the <dt-bindings/gpio/gpio.h> header instead of using
hardcoded values for the GPIO flags. Eradicate the totally
bogus "0x4" flag used and set that to GPIO_ACTIVE_HIGH as is
proper, switch the inverted card detect on the Snowball to
flag using GPIO_ACTIVE_LOW instead of using the MMC-specific
inversion flag.

250656b4bc ARM: ux500: push down Rohm TS to STUIB
The Rohm touchscreen reset and IRQ lines were registered and
configured at the HREF board level of the design, but it is an
integral part of the UIB (User Interface Board). Fix this by
pushing down the pin control node to the u8500 UIB file.

1d8aca9df6 ARM: ux500: fix MMC/SD card regression
Ux500 is regressing due to commit
a21763a0b1
"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.

1637d480f8 pinctrl: nomadik: force-convert to generic config bindings
This converts the Nomadik pin controller and all associated device
trees to use the standard, generic config bindings for pin controllers.
There are no such device trees deployed in the wild so this is
safe to do to set a good example.

Move the AB8500 muxing and biasing settings over from the board

the AB8500: HREF prior to v60, v60plus and Snowball. Set up these
GPIO lines using hogs, just like in the board file.

a1ab5e4c80 ARM: ux500: Configure regulator for I/O voltage for SD-card slot
To be able to enable SDR12|25 for SD-cards, we needed to fixup the
configuration in DT of the gpio regulator, which handles the signal
voltage level. Some configuration were missing and some were wrong.

This moves over the configuration of the GPIO keys (used for
proximity sensor and Hall effect sensor) from the static pin
configuration file to the device tree. As part of the exercise,
implement the GPIO keys properly in a per-UIB file as this
setup actually differs with each UIB.

01dc909fa1 ARM: ux500: split the HREF DTS files from two to four
As the device tree conversion did away with the ability to
auto-detect the UIB (User Interface Board) version from attempting
to read an I2C address, we now have to pass the knowledge of
what UIB is mounted through the device tree. This gives rise
to four possible board permutations:

- HREF prior to v60, ST UIB (hrefprev60-stuib)
- HREF prior to v60, TVK1281618 UIB (hrefprev60-tvk)
- HREF v60 and later, ST UIB (href60plus-stuib)
- HREF v60 and later, TVK1281618 UIB (hrefv60plus-tvk)
