2016-03-21apalis_t30: ixora: optionally support leds, switch, foff and wdisableMarcel Ziswiler
The Ixora carrier board has a few MXM3 pins repurposed as follows: Functionality MXM3 Pin LED4_RED 146 LED4_GREEN 162 LED5_RED 156 LED5_GREEN 152 PCIE1_WDISABLE_N 144 SW3 160 UART2_3_RS232_FOFF_N 164 This patch allows uncommenting an IXORA define in the board header file in order to make use of those repurposed pins. Please note that those pins are usually used for the 8-bit MMC/SD slot aka Apalis MMC1 and the SDHCI controller/driver unfortunately changes the output driver behaviour in a way preventing any regular GPIO use. This patch therefore explicitly does not register the SDHCI driver on this controller instance in the Ixora case to avoid this.

2015-09-26apalis/colibri_t30: usb: fix performance regressionMarcel Ziswiler
Unfortunately that utmi_phy_remotewake_detected() function gets called one too many times even quite continuously during data transfers and putting an mdelay() in there has a rather adverse effect on the overall system performance including of course degrading USB transfer speeds. Moving the system lock-up avoidance hack further down into the if clause improves the performance again as this typically is only ever evaluated once upon actually plugging something in behind a hub. This fixes a performance regression introduced by the following commit: apalis/colibri_t30: usb: fix low-speed issue hack 629b91fa046df5213ed3312d2e2b8683e6bdd70c

2015-06-03colibri_t20: improve pmic rtc accuracyMarcel Ziswiler
It looks like our crystal load capacitance is way off as we just copied NVIDIA's default setting being the lowest possible 1.5 pF due to their boards having 20 pF external caps while our hardware does not have any external caps assembled and we should use the highest 12.5 pF setting.
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.

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

2014-12-01apalis_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"

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

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.
