edf0093732 mx6: ddr: Allow changing REFSEL and REFR fields
Currently MX6 SPL DDR initialization hardcodes the REF_SEL and
REFR fields of the MDREF register as 1 and 7, respectively for
DDR3 and 0 and 3 for LPDDR2.

Looking at the MDREF initialization done via DCD we see that
boards do need to initialize these fields differently:

$ git grep 0x021b0020 board/

So introduce a mechanism for users to be able to configure
REFSEL and REFR fields as needed.

Keep all the mx6 SPL users in their current REF_SEL and REFR values,
so no functional changes for the existing users.

Added removal of the fsl,ext-reset-output property in the wdog node for board

5a08ad6fdc imx: ventana: add dt fixup for GW16082 irq mapping
The GW16082 mini-PCI expansion mezzanine uses a TI XIO2001 PCIe-to-PCI
bridge with legacy INTA/B/C/D interrupts. These interrupts are assigned
in the reverse order according to the PCI spec.

If the TI bridge is found on the Ventana PCI bus, add device-tree nodes
according to bus enumeration explicitly defining the interrupt mapping
to override the default PCI mapping in the Linux kernel. This allows
the GW16082 to work with upstream kernels that support device-tree
irq parsing.

34b080b79c imx: ventana: add fdt fixup to enable UHS-I support on selected boards
UHS-I support is available on Ventana boards with micro-SD sockets depending
on the board revision. For backwards compatibility to not break users
who have old bootloaders and newer kernels the device-tree on boards with
microSD disables UHS-I support by default by defining the no-1-8-v property
in the esdhc controller node. For models/revisions that support switchable
1.8V/3.3V I/O which is detectable by the presence of a pull-down on the
SD3_VSELECT pin we remove that property to enable support in the kernel.

Additionally we add SD3_VSELECT to the pinmux for clarity (even though U-Boot
does not currently support UHS-I modes requiring 1.8V I/O).

fe63fcb6ca imx: ventana: remove several EEPROM config bit dependence
Removed several EEPROM bit dependencies:
 - for dt aliases that don't exist and thus don't ever do anything
   (pcie,lvds1,uart*,vpu,csi*,hdmi_in,hdmi_out,cvbs_in,cvbs_out,gps)
 - for features that don't effect bus ordering or have no detrimental affect
   if erroneously enabled when not present (ahci,nand,i2c*)
 - for features that have little to no impact on being erroneously enabled
   but high impact if erroneously disabled (can*, spi*)
 - for features that have an high adverse affect of not being set when they
   should and no adverse affect of being set when they
   shouldn't (ipu*).

Removing these means the following:
 - these no longer are supported with the econfig command
 - these no longer affect the device-tree in any way

5c55572ff7 imx: ventana: remove dependence on EECONFIG_SATA eeprom feature bit
The MSATA feature is a board-specific feature on Gateworks Ventana boards.

In most cases a 2:1 mux will steer either PCIe or SATA to a miniPCIe socket
through an MSATA_EN gpio. In these such cases assign the gpio in the board
specific struct and use its presence to determine if we default the GPIO to
PCIe and if we later steer it according to hwconfig.

f17a9af846 imx: ventana: enable pwm device-tree property based on hwconfig
Most Ventana boards have a connector with off-board digital-I/O signals
including some that can be pinmuxed as either a PWM or a GPIO. The hwconfig
env variable is used to configure these and they will be pinmuxed according
to this configuration in the bootloader.

This patch adds a device-tree fixup that will enable the pwm controller
nodes appropriately for digital-I/O's that are configured as pwm via hwconfig
so that the pin can be used with the Linux kernel /sys/class/pwm API.

shy on the IMX6Q operating at 1GHz we set it to the max we can and leave it
up to the kernel to implement a regulator driver for the LTC3676 and put
the LDO's in bypass mode which allows us to drop the voltages by 125mV
respectively.

e895a4b06f fdt: Allow ft_board_setup() to report failure
This function can fail if the device tree runs out of space. Rather than
silently booting with an incomplete device tree, allow the failure to be
detected.

Unfortunately this involves changing a lot of places in the code. I have
not changed behvaiour to return an error where one is not currently
returned, to avoid unexpected breakage.

Eventually it would be nice to allow boards to register functions to be
called to update the device tree. This would avoid all the many functions
to do this. However it's not clear yet if this should be done using driver
model or with a linker list. This work is left for later.

155fa9af95 spi: mxc: fix sf probe when using mxc_spi
MXC SPI driver has a feature whereas a GPIO line can be used to force CS high
across multiple transactions. This is set up by embedding the GPIO information
in the CS value:

cs = (cs | gpio << 8)

This merge of cs and gpio data into one value breaks the sf probe command:
if the use of gpio is required, invoking "sf probe <cs>" will not work, because
the CS argument doesn't have the GPIO information in it. Instead, the user must
use "sf probe <cs | gpio << 8>". For example, if bank 2 gpio 30 is used to force
cs high on cs 0, bus 0, then instead of typing "sf probe 0" the user now must
type "sf probe 15872".

This is inconsistent with the description of the sf probe command, and forces
the user to be aware of implementaiton details.

Fix this by introducing a new board function: board_spi_cs_gpio(), which will
accept a naked CS value, and provide the driver with the relevant GPIO, if one
is necessary.
