2015-04-14ARM: tegra: hack to make IT parts operate like commercial temp for nowMarcel Ziswiler
As NVIDIA so far was unable to provide us with any proper speedo numbers for their industrial temperature aka IT parts just make SKU 0xB0 aka T30IQS-Ax behave identical to the regular commercial temperature 0xB1 aka T30MQS-Ax for the SKU to speedo ID conversion. This prevents them to fall back to fixed 600 MHz operation and crashing thermal throttling once kicking in due to missing table entry causing a null pointer exception.

2014-12-18apalis_t30: optional mmc uhs support (v1.1a and later hw)Colibri_T30_LinuxImageV2.3Beta5_20141219Colibri_T20_LinuxImageV2.3Beta5_20141219Apalis_T30_LinuxImageV2.3Beta5_20141219Marcel Ziswiler
This patch adds optional UHS support for the 8-bit MMC controller. Please note that this requires V1.1A or later module hardware plus the pull-up resistors on the data as well as the command signal lines of your carrier board need to be removed (e.g. R46 to R54 on our Apalis Evaluation Board V1.1A). If those pre-requisites are met support can be enabled using the following kernel command line parameter: mmc_uhs=1
2014-12-18apalis/colibri_t30: usb: fix low-speed issue hackMarcel Ziswiler
Certain low-speed USB devices were not detected correctly when plugged into a running system.
2014-12-01apalis_t30: implement power button optionally acting as power-keyMarcel Ziswiler
Both the Apalis EvalBoard as well as Ixora allow their LTC2954 pushbutton on/off controller to optionally initiate orderly shutdown via GPIO interrupt on GPIO5 upon short power button press (short here meaning really short unless C137 resp. C35 is assembled). For this to work the following wiring is required: Apalis EvalBoard V1.1a X61-4 to X2-6 Ixora V1.0a X5-4 to X27-17 For systemd/logind to actually use this as a power-switch a custom udev rule /etc/udev/rules.d/70-power-switch-apalis_t30.rules as follows is required: # Specific rule for apalis_t30: # # Apalis T30's power button is not part of the kernel acpi subsystem. # Let's manually add the power-switch tag to control its behaviour with # systemd/logind ACTION=="remove", GOTO="power_apalis_t30_end" SUBSYSTEM=="input", KERNEL=="event1", TAG+="power-switch" LABEL="power_apalis_t30_end"
2014-12-01apalis_t30: implement optional force off gpio supportMarcel Ziswiler
Both the Apalis EvalBoard as well as Ixora allow their LTC2954 pushbutton on/off controller to optionally be forced off by using a GPIO. This patch implements this upon poweroff/shutdown using Apalis GPIO6 which happens to be internally pulled-up upon power-on reset (otherwise we would immediately get powered off again). For this to work the following wiring is required: Apalis EvalBoard V1.1a X2-A5 to X61-5 Ixora V1.0a X27-18 to X5-5
2014-12-01apalis_t30: fix wake-up-key (formerly power-key)Marcel Ziswiler
The wake-up-key (formerly power-key) on MXM3 pin 37 aka WAKE1_MICO is actually active-low due to the EvalBoard v1.1a having 4.7 K pull-up. This patch fixes this. While at it also get rid of the custom wakeup_key handling blindly copied from T20 as non of the other T30 boards do this and it anyway might only be required for LP0 which we anyway do not support so far.
2014-10-28apalis/colibri t30: fix audio hub lock-upMarcel Ziswiler
This patch fixes a clock related audio hub driver lock-up observed when booting with mainline U-Boot which we are in the process of migrating to now.

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.

2014-07-21mmc: 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.

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.
