imx: ventana: add fdt fixup to enable UHS-I support on selected boards

2016-05-31T15:26:27+00:00

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).

imx: ventana: remove several EEPROM config bit dependence

2016-05-31T15:26:00+00:00

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

imx: ventana: remove dependence on EECONFIG_SATA eeprom feature bit

2016-05-31T15:25:47+00:00

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.

imx: ventana: enable pwm device-tree property based on hwconfig

2016-05-31T15:25:31+00:00

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.

imx: ventana: export backlight gpio after gpio driver is available

2016-05-31T15:25:02+00:00

Calling request_gpio to register bklt_gpio with the GPIO driver had no effect
in setup_display called from early board init (although pinmuxing it and
configuring it as output-low does do what it should). Therefore move the
request_gpio later in enable_lvds so that its registered for use by the
gpio command if LVDS is actually enabled.

The GSC Temperature sensor is a 2's complement value - adjust accordingly
for negative temperatures.
