2017-01-11	apalis_t30: fix pcie clock and reset not conforming to specification	Marcel Ziswiler
	Fix PCIe clock and reset not conforming to specification by moving PCIe reset handling including the PLX PEX 8605 errata 5 workaround from the board platform data into the right places timing wise in the PCIe driver itself. Also add a kernel command line argument to allow using the Apalis GPIO7 as a regular GPIO rather than for above mentioned PLX PEX 8605 workaround: pex_perst=0 Signed-off-by: Marcel Ziswiler <marcel.ziswiler@toradex.com> Acked-by: Max Krummenacher <max.krummenacher@toradex.com>
2016-03-21	apalis_t30: ixora: optionally support leds, switch, foff and wdisable	Marcel 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.

2014-12-01	apalis_t30: implement power button optionally acting as power-key	Marcel 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"
2014-12-01	apalis_t30: implement optional force off gpio support	Marcel 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
2014-01-22	colibri_t20/colibri_t30/apalis_t30: remove TEGRA_FB_VGA defines	Stefan Agner
	Remove TEGRA_FB_VGA defines and use VGA as default. Since initial mode is now configureable through kernel cmd line parameter, we don't need those compile time helpers.
2013-08-30	apalis_t30: export Apalis GPIOs to userspace via sysfs	Marcel Ziswiler
	Up to now only the LVDS transceiver controlling GPIOs were exported. This patch adds the generic Apalis GPIOs to the list of via sysfs to userspace exported ones as well.
2013-06-24	apalis_t30: set local critical temperatur to 95°C	Max Krummenacher
	If the local critical temperature is reached the power is unconditionally switched off. At 70°C ambient the default of 85°C can be reached. So increase the limit in the hwmon chip to 95°C.
2013-03-14	apalis_t30: default full HD LVDS resolution	Marcel Ziswiler
	By default configure for LG LP156WF1 15.6 inch full HD dual channel LVDS panel.
2013-03-02	apalis/colibri_t30: clean-up defines in header file	Marcel Ziswiler
	Re-arrange defines in header file.
2013-03-02	apalis/colibri_t30:	Marcel Ziswiler
	Get rid of spurious AC_PRESENT_GPIO/INT defines.
2013-02-19	apalis_t30: add generic Apalis GPIO defines	Marcel Ziswiler
	Add defines for the generic Apalis GPIOs 1 to 8 and the special use thereof on the Apalis Evaluation Board: FAN_EN on GPIO8: enable FAN supply on X35 PEX_PERST_N on GPIO7: reset PCIe switch for X43, X44 and X45 TOUCH_WIPER on GPIO6: optional touch wiper GPIO
2013-01-24	tegra: apalis_t30: initial Toradex Apalis T30 L4T support	Marcel Ziswiler
	Tested on early prototype Apalis T30 V1.0a module. Known issues: - ADC not integrated yet. - HDA not integrated yet. - CEC not integrated yet. - IrDA not integrated yet. - Keys not integrated yet therefore no way to wake from suspend. - 8-bit MMC1 slot card detection interrupt not working despite detection GPIO successfully being tested with GPIOConfig. Note: even 8-bit cards work fine if already plugged-in during boot. - PCIe limited to internal Gigabit Ethernet chip for now due to our proprietary way of resetting other ports which requires further integration into NVIDIA's driver.
