Few trivial omap MMC regression fixes for card voltages where
the syscon areas for PBIAS regulator were missing "simple-bus"
that prevents probing of the children in the mapped region.

This probably was not noticed earlier as the bootloader has
already configured the regulator for the card in the slot.

The PCIe interrupts are also routed through the GPC. This has been
missed from the conversion to stacked IRQ domains as the PCIe
controller uses an explicit interrupt map and thus doesn't inherit
the SoC global interrupt parent.

The "cpus" node cannot be inside the "soc" node, while this
works for the CoreSight blocks, the early boot code will look
for "cpus" directly under the root node, so this is a hard
convention. So move the CPU nodes.

Augment the "reg" property to match what is actually in the
hardware: 0x300 and 0x301 respectively.

Then add an SMP enablement type to be used by the SMP init
code, "ste,dbx500-smp".

ARM: OMAP2+: hwmod fixes for v4.2-rc

Two fixes against v4.2-rc1.  The first, for DRA7xx platforms,
corrects some incorrect GPMC hardware description data.  The
second one will ensure that the hwmod code will wait for any
module with CPU-accessible registers to become ready before
attempting to access it.

Basic build, boot, and PM test logs are available here:

http://www.pwsan.com/omap/testlogs/omap-hwmod-a-for-v4.2-rc/20150723065408/

Note that I do not have a DRA7xx or AM43xx board, and therefore
cannot test on those platforms.

For hwmods without sysc, _init_mpu_rt_base(oh) won't be called and so
_find_mpu_rt_port(oh) will return NULL thus preventing ready state check
on those modules after the module is enabled.

This can potentially cause a bus access error if the module is accessed
before the module is ready.

Fix this by unconditionally calling _init_mpu_rt_base() during hwmod
_init(). Do ioremap only if we need SYSC access.

Eventhough _wait_target_ready() check doesn't really need MPU RT port but
just the PRCM registers, we still mandate that the hwmod must have an
MPU RT port if ready state check needs to be done. Else it would mean that
the module is not accessible by MPU so there is no point in waiting
for target to be ready.

e.g. this fixes the below DCAN bus access error on AM437x-gp-evm.

Currently PCIe DT bindings are broken. PCIe driver can't function
without having a SerDes driver that provide the phy configuration.
On K2E EVM, this causes problem since the EVM has Marvell SATA
controller present and with default values in the SerDes register,
it seems to pass the PCIe link check, but causes issues since
the configuration is not correct. The manifestation is that when
EVM is booted with NFS rootfs, the boot hangs. We shouldn't enable
PCIe on this EVM since to work, SerDes driver has to be present as
well. So by default, the PCIe DT binding should be disabled in SoC
specific DTS. It can be enabled in the board specific DTS when the
SerDes device driver is also present.

So fix the status of PCIe DT bindings in the SoC specific DTS to
"disabled". To enable PCIe, the status should be set to "ok" in
the EVM DTS file when SerDes driver support becomes available in
the upstream tree.

Since dm9000 driver added support for a vcc regulator, platform data
based platforms have their ethernet broken, as the regulator claiming
returns -EPROBE_DEFER and prevents dm9000 loading.

This patch fixes this for all pxa boards using dm9000, by using the
specific regulator_has_full_constraints() function.

This was discovered and tested on the cm-x300 board.

Audio-in was incorrectly routed to Line In. It should be Mic3L as per
schematic.

Using mic-bias voltage at 2.0v (<0x1>) does not work for some reason. There
is no voltage seen on micbias (R127). Mic-bias voltage of 2.5v (<0x2>) works.
I see voltage of 2.475v across GND and micbias.

With these changes, I can record audio with a pair of proliferate TRRS earbuds.

CONFIG_HAVE_ARM_SCU only gets selected if CONFIG_SMP is selected in an OMAP
system, however AM43XX needs this option regardless of CONFIG_SMP and also
for an AM43XX only build as it is important for controlling power in the SoC.
Without this we cannot suspend the CPU for SoC suspend or cpuidle. The
ARM Cortex A9 needs SCU CPU Power Status bits to be set to off mode in order
for the PRCM to transition the MPU to low power modes.

The i.MX fixes for 4.2:
 - Correct compatible string for i.MX27 GPT which actually shares the
   same programming model as i.MX21 GPT rather than i.MX1 one.
 - Add missing #io-channel-cells property for i.MX23 LRADC device, which
   is required for the device to be an IIO provider.
 - Correct HSYNC/VSYNC pins and add ddc-i2c-bus property for TVE device
   on imx53-qsb to work properly.
 - Always enable PU domain if CONFIG_PM is not set.  This fixes a couple
   of failure scenarios which will hang the system if one of the devices
   in the PU domain is accessed.

Ux500 is regressing due to commit
a21763a0
"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
necessary to do if we want to remove one of the serial ports,
since userspace depends on console to be present on ttyAMA2

Boot process is halting in midway because some of the necessary voltage
regulators are deemed unused and subsequently powered off, leading to
a completely unresponsive system.

Most of the device nodes had correct voltage regulator attachments.
Yet these nodes had to set stricter enforcement on them through
'regulator-boot-on' and 'regulator-always-on' to function correctly.

The consumers of the regulators this commit affect are the followings:

	DCDC1: vdd_1v8 system supply, USB-PHY, and ADC
	DCDC2: Core domain
	DCDC3: MPU core domain
	 LDO1: RTC
	 LDO2: 3v3 IO domain
	 LDO3: USB-PHY; not a boot-time requirement
	 LDO4: LCD [16:23]

All but LDO3 need to be always-on for the system to be functional.

Additionally regulator-name properties have been added for the kernel to
display the name from the schematic. This will improve diagnostics.

For Gumstix Overo COMs, the u-boot bootloader typically passes an
argument specifying the default display via the omapdss.def_disp
parameter.  When a default display is specified, DSS2 tries to match
this name with either the device tree label (e.g. label=dvi) or,
failing this, the device tree alias (e.g. label=display0). Update the
panel names for the 'lcd43' and 'lcd35' displays in the device tree
such that they match the names passed by u-boot.
