2016-07-28imx: ventana: add dt fixup for eth1 mac-addressTim Harvey
Ventana boards with a PCI Marvell Sky2 GigE MAC require the MAC address to be placed in a DT node in order for the mainline linux driver to obtain it. Signed-off-by: Tim Harvey <tharvey@gateworks.com>
2016-07-28imx: ventana: add dt fixup for GW16082 irq mappingTim Harvey
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. Signed-off-by: Tim Harvey <tharvey@gateworks.com>

2016-05-31imx: ventana: add fdt fixup to enable UHS-I support on selected boardsTim Harvey
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). Signed-off-by: Tim Harvey <tharvey@gateworks.com>

2016-05-31imx: ventana: enable pwm device-tree property based on hwconfigTim Harvey
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.

2016-05-31imx: ventana: export backlight gpio after gpio driver is availableTim Harvey
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. Signed-off-by: Tim Harvey <tharvey@gateworks.com>

The fdt_file1 and fdt_file2 vars provide fallbacks for the fdt file loading script. There is no need to allow the user to override these as if they want to specify the fdt, they should do so in the first attempt which is the fdt_file var. Signed-off-by: Tim Harvey <tharvey@gateworks.com>

2015-04-22imx: ventana: set HDMI video in to yuv422bt656 for GW551x-ATim Harvey
The initial revision of the GW551x does not connect enough signals between the HDMI receiver and the IMX6 CSI for 16bit capture mode necessary for yuv422smp capture. Future revisions will, but for the initial rev force it to yuv422bt656 mode which requires an 8bit video data bus. Signed-off-by: Tim Harvey <tharvey@gateworks.com>
2015-04-22imx: ventana: use hdmiinfmt env var to override HDMI capture formatTim Harvey
The HDMI receiver used on the GW54xx and GW551x has a 16bit video data bus interconnect between it and the IMX6 CSI. This can be used in two different modes, each having advantages and disadvantages. Allow the hdmiinfmt env var to specify which format is desired (yuv422smp or yuv422bt656). Signed-off-by: Tim Harvey <tharvey@gateworks.com>

2015-04-22imx: ventana: add 'gsc wd' command for enabling and disabling GSC watchdogTim Harvey
This adds information about the Gateworks System Controller to the gsc command such as the firmware version, firmware CRC and status of the GSC watchdog (if its enabled and if its tripped). Additionally the 'gsc wd' command can be used to enable or disable the watchdog with the following usage: gsc wd enable [30|60] gsc wd disable Note that the GSC registers are battery-backed by the GSC coincell so once eanbled, they remain enabled across power-cycles or until either the GSC firmware has been updated or FLASH has been re-programmed by the Gateworks JTAG adapter.

2015-04-22imx: ventana: add DT fixup for GW54xx compatibility with older kernelsTim Harvey
Certain older kernels in use by some customers erroneously define a uart3 for GW54xx with a pinmux that conflicts with NAND. This will remove that node to avoid such conflicts. Signed-off-by: Tim Harvey <tharvey@gateworks.com>
2015-04-22imx: ventana: added DT fixup for GW551x-A video inputTim Harvey
The GW551x-A revision does not have the CSI0_DATA_EN pin connected, therefore we need to make sure that signal is not muxed to the CSI_DATA_EN signal internally and do so by steering it to the unused GPIO5_IO20. We do this so that the kernel device-tree can properly define the signal for RevB and beyond boards that do have this hooked up properly and require it.

2015-04-22imx: ventana: disable IMX6 watchdogs on GW51xx RevA and RevBTim Harvey
A board level errata causes the IMX6 watchdog to be unstable on the GW51xx RevA and RevB boards which can cause the watchdog to trip extremely early (under 5seconds) under certain operating conditions.

2015-04-22imx: ventana: set LTC3676 PMIC to appropriate values per datasheetTim Harvey
The IMX6 Datasheets specifies that when the IMX6 LDO is enabled (internal Anatop LDO's for VDD_ARM, VDD_SOC, and VDD_xPU) you need to provide 1350mV on VDD_ARM_IN and VDD_SOC_IN for IMX6Q@1GHz (Automotive) and 1275mV for IMX6DL@800MHz (Industrial). While we are still about 50mV 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.

2014-11-21fdt: Allow ft_board_setup() to report failureSimon Glass
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.

2014-09-24spi: mxc: fix sf probe when using mxc_spiNikita Kiryanov
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.
