e49621b357 imx: ventana: make RS232 enable board specific
Not all Ventana boards have an RS232 transceiver, make it board specific.

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).

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.

18e02ffe5e arm: imx6: novena, gw_ventana: Fix use of pfuze100 bit definitions
The following patch changed the PFUZE100 swbst register bit definitions
and broke PMIC configuration on multiple boards, at least on the novena
and gw_ventana. This patch fixes it.

9a83a81545 imx: ventana: various board-specific GPIO config updates
- Added iomux for CAN_STBY and RS484_TEN (GW52xx/GW53xx/GW54xx/GW551x)
- Moved iomux of USBHUB_RST# out of board_ehci_hcd_init so that it is
  done regardless of USB being initialized in bootloader
- Added usb_sel iomux/hwconfig for GW552x
- Fixed mezzanine DIO for GW54xx
- Fixed PANLEDR# for GW54xx
- Fixed dio iomux/hwconfig for GW552x
- Fixed dio iomux for GW551x
- removed redundant #define

6d38f3a85d imx: ventana: detect pmic using i2c probe instead of board model
Avoid requiring board-model and probe pmic by its i2c address.
This is in preparation for being able to call pmic_setup() from SPL
and not need board type.

e56c5791af imx: ventana: split out common functions between SPL and uboot
Move shared functions used by both SPL and U-Boot to common.c:
 - setup_iomux_uart() and uart pad config
 - gpio pad config

In the process also moved the following to common.c in preparation for
calling it from the SPL:
 - split i2c setup into a shared function
 - move pmic init to setup_pmic() function to call directly from
   power_init_board()
 - split gpio setup into early (iomux and default pin config)
   and late (output configuration based on env)
