2014-07-25apalis/colibri t30: use hda hdmi audio and split sound initMarcel Ziswiler
Use HDA HDMI audio now on Colibri T30 as well allowing for up to 7.1 multi-channel playback. Split board sound initialisation between Apalis and Colibri T30 in order to distinguish better between default SPDIF being supported out-of-the-box on Apalis vs. this being an optional feature for the Colibri. Therefore remove SPDIF for the Colibri T30. While at it add csus clock required for vi_sensor camera master clock on Apalis T30 and clk_out_2/extern2 for Colibri T30, fix debug UART1 initialisation, get rid of spurious CONFIG_SND_USB enable and further clean-up both board platform data files.
2014-07-25apalis/colibri t20/t30: enable fhandle for systemdMarcel Ziswiler
Enable CONFIG_FHANDLE required for systemd >= 209 according to While at it put them all 3 on par concerning ARM Errata configuration.
2014-07-22apalis/colibri t20/t30: fix/introduce spi device controller dataMarcel Ziswiler
Fix (Colibri) resp. introduce (Apalis) SPI device controller data to properly use HW based chip select with one clock of setup and hold time each for both MCP2515 CAN controller(s) as well as spidev.
2014-07-21mmc: tegra: use 1.8V quirk only on affected instancesStefan Agner
The 1.8V quirk also affected the internal eMMC which disabled newer modes such as SDR50, SDR104 and DDR50. This in turn lead to an out of spec usage since the clock was still 50MHz. By creating a no_1v8 field in the platform data we can now enable this work around on a per-instance basis. Hence we enable the quirk only on the controllers which are connected to the external SD-slots.

2014-07-08media: vi driver on Colibri T20 is working againWojciech Bieganski
This commit resolves an issue of non-working vi camera driver on Colibri T20 occured after a l4t-r16-r4 merge.
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!
2014-05-09colibri t20/t30: clarify mcp2515 resetMarcel Ziswiler
The MCP2515 on the Colibri EvalBoard V3.1a actually uses regular system reset aka RESET_OUT# on SODIMM 87 to reset the MCP2515. Therefore clean-up resp. remove any MECS Tellurium legacy in that respect. While at it adjust copyright year, re-order some include, clean-up some struct spacing, re-order clocks and improve some comments.

Activate Fusion touchscreen driver. Use GPIO 5/6 as pen down/reset GPIO and provide a helper function to free the GPIO before the driver requests them.
2014-01-29colibri_t20/colibri_t30: use new platform data for fusion touchscreenStefan Agner

2014-01-29video: tegra: kernel parameters to change RGB clock polarityStefan Agner
Allow to change clock polarity for RGB display output using the keywords outputen/pixclockpol/vsync and hsync. Add them right after the driver specification, use 0/1 to specifiy high/low polarity, e.g. video=tegrafb0:pixclockpol:1,800x480
2014-01-29video: tegra: remove special clocks for Tegra 2Stefan Agner
Remove special clocks for Tegra 2, but use backup clock source instead. This allows to run all common used resolution within the drivers -1/+9% allowed band for pixelclock exactness.
2014-01-22colibri_t20/colibri_t30/apalis_t30: remove TEGRA_FB_VGA definesStefan Agner

2013-12-09tegra: pcie: use integer for root_bus_nrStefan Agner

On Colibri T30 this was observed when enabling it using the fbcon=map:1 boot argument. This fix curtsey of Bibek Basu from NVIDIA explicitly enables PLLA during early clock initialisation which avoids a later race with the display driver on DC1.
