In order to avoid any floating SD card detect pins as may e.g. happen on Ixora V1.1A pull them all up. Signed-off-by: Marcel Ziswiler <marcel.ziswiler@toradex.com> Acked-by: Dominik Sliwa <dominik.sliwa@toradex.com>

2014-05-09colibri t20/t30: add spi controller platform data for hw csMarcel Ziswiler
Add SPI controller platform data required for use of hardware chip selects. While at it pull-up SPI chip select pin due to NVIDIA's designers taking the term chip select a little too personal: they indeed only select a chip otherwise all the chip select pins are just left floating!
2013-03-24colibri_t20: fix menu-keyMarcel Ziswiler
Due to a strong pull-down on the menu-key multiplexed ACC1_DETECT pin Android unintentionally entered safe-mode. Fix this by making the menu-key active-high as well.
2013-03-12colibri_t20/30: can: integrate mcp251x and sja1000 supportMarcel Ziswiler
Integrate CAN support for the Colibri Evaluation Board V3.1a with built-in MCP2515 SPI CAN controller resp. the Colibri Evaluation Board V2.1c with its built-in SJA1000 CAN controller connected to the GMI bus. The following kernel configuration needs to be enabled as well: CONFIG_CAN CONFIG_CAN_RAW CONFIG_CAN_BCM CONFIG_CAN_DEV Plus depending on the Evaluation Board revision: CONFIG_CAN_MCP251X or CONFIG_CAN_SJA1000 CONFIG_CAN_SJA1000_PLATFORM Optional support for 32-bit GMI as well as xPOD CAN on MECS Tellurium for Colibri T20 is provided via commented defines in arch/arm/mach-tegra/board-colibri_t20.h.
2013-01-11colibri_t20: fix GMI_WR_N on SODIMM pin 93 RDnWRMarcel Ziswiler
Looks like we mixed up the low-active buffer enable GPIOs. This fixes GMI_WR_N on SODIMM pin 93 RDnWR curtsey Tord Andersson from Endian Technologies AB.
2012-12-17colibri_t20: fix power key on EvalBoard v3.1aMarcel Ziswiler
As the new Colibri Evaluation carrier board v3.1a uses SODIMM pin 45 as IrDA transceiver SD with a 100 K pull-down we revert to using the power key as high active.
2012-12-17colibri_t20: gpio-keys: enable pull-upsMarcel Ziswiler
GPIO keys configured as active-low either require pull-ups on the carrier board or via pin-muxing. We enable the later for now.
2012-12-17colibri_t20: pin-mux: re-work function tri-statingMarcel Ziswiler
Use GPIO inputs for function tri-stating rather than pin group tri-stating to avoid influencing neighbouring pins. While at it get rid of most pull-up/downs and a lot of commented out stuff.
2012-12-17colibri_t20: camera: rename CAMERA_INTERFACE defineMarcel Ziswiler
Rename CAMERA_INTERFACE to COLIBRI_T20_VI which stands for video input to be more in-line with Colibri T30.
2012-11-14colibri_t20: fix keyboard GPIO resp. GPIO K6Marcel Ziswiler
SODIMM pin 135 is really GPIO K6 multiplexed with ACC1_DETECT. Unfortunately the later can't be tri-stated but since it is anyway always an input it should not interfere. Please note however that this SODIMM pin is rather low resistance.
2012-10-01tegra: colibri_t20: fix pwm backlightMarcel Ziswiler
Fix PWM backlight by using PWM<A> rather than PWM<C> by default. Invert brightness value due to unified TFT interface displays (e.g. EDT ET070080DH6) inverted LEDCTRL pin behaviour (e.g. 0V brightest vs. 3.3V darkest) and use PWM frequency of 1 kHz as recommended. Add comment about PWM pin muxing. While at it do some ifdef and indentation clean-up.
2012-09-10tegra: colibri_t20: incorporate l4t-r16 changesMarcel Ziswiler
Incorporate L4T R16 changes from NVIDIA Ventana. Note: USB OTG port not functional as of yet.
