Use new modedb based framebuffer settings by defining default_mode
in the display controllers platform data. Also impelmented the
fallback logic to this default_mode in case no kernel cmd line
parameter was set.
|
|
Allow to specify framebufffer videomode using kernel command line
parameters. NVIDIAs binary X driver later on picks up those settings
and start X with current mode settings, if no EDID data are available.
|
|
Disable hardware statistics monitor for AVP due to it completely
hanging upon boot on certain Colibri T20 V1.2a modules.
|
|
Make use of the new STMPE ADC driver to expose the four free ADC
channels on the STMPE811 to userspace.
|
|
This adds an ADC driver for the STMPE device using the industrial
input/output interface. The driver supports raw reading of values.
The driver depends on the MFD stmpe driver. If the touchscreen
block is enabled too, only for of the 8 ADC channels are available.
|
|
In order to use the auxiliar ADC inputs of STMPE811 devices we need
to add resources for the ADC block. Also move the ADC macros from
the touchscreen driver to the general header file. We will need them
for the ADC driver in future.
|
|
The drivers internal root_bus_nr used to be u8 which lead to a wrong
error detection in bus_to_port. Bus number can be -1 in case bus is
not scanned yet. Thanks to James pointing that out.
|
|
The voltage table for the SM2 regulator on TPS658643 was wrong. However,
since the requested voltage of 1.8V was at the right place, the system
worked fine nonetheless.
|
|
The port used for KEY_BACK does not support wakeup (no wake PIN). Remove
the wake flag, this prevents unbalanced irq warning messages.
|
|
Add GPIO keyboard platform device configuration. Currently only the power key
is defined which is registred as wake key as well in order to wake the SoC when
in sleep mode (MXM3 37/WAKE1_MICO).
|
|
After suspend, mode filter might be called with empty yres. This leads
to division by zero when checking aspect ratio. Return as invalid mode
when yres is zero.
|
|
When enabling SATA clocks, the PCIE clocks are enabled as well since
those are the parent clocks. In order to enable this parent clocks,
the PCIE regulator avdd_plle needs to be enabled. The resume path used
to freeze because the PCIE PLL did not lock.
|
|
Remove vdd_hdmi_con regulator from dc1 since we don't have a dedicated
regulator for this connector on our baseboards.
|
|
Use TPS6591X IRQ base define to calculate correct IRQ number.
|
|
Use TPS6591X base defines to make sure the chip gets its own irq range rather
than interfer with the STMPE chip.
|
|
Fix errors when registration fails, correctly unregister the
platform device.
|
|
Clean-up GPIO definitions and names (e.g. use LVDS_ defines, BKL1_ON
rather than BL_ON and HDMI1_HPD rather than hdmi_hpd).
|
|
When hotpluging hdmi the read of edid often fails.
Add up to 4 retries with a 500ms delay before giving up.
|
|
This gives the DDR3L memory settings for 400MHz/800MHz.
The boot memory speed must be 400MHz for this to work, i.e.
the 400MHz BCT must be used.
|
|
If the boot console is RS232 and RX is left floating this leads
to arbitrary sys requests including reboots...
(RX is left floating on the evaluation boards if USB to serial is
jumpered but USB is not connected)
|
|
Reworked driver in order to properly support default watchdog api
such as triggering by writing a character and disable by sending
a magic character. Renamed ENABLE_ON_PROBE to ENABLE_HEARTBEAT
which triggers the watchdog using the interrupt service routine.
|
|
Initialisation of the framebuffer console on DVI-D aka HDMI always
failed on monitors which report the vertical front porch to be 1
in their EDID.
The fix now changes also the modedb and not only the list of
videomodes with a compatible timing.
This was particularly bad on Apalis T30 where this is activated
by default. On Colibri T30 this was observed when enabling it using the
fbcon=map:1 boot argument.
|
|
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.

Initialisation of the framebuffer console on DVI-D aka HDMI sometimes
failed. This was particularly bad on Apalis T30 where this is activated
by default. 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.

|
|
In preparation for the new Apalis resp. Colibri T30 production lots
with either T30IQS-P-A3 or T30MQS-P-A3 chips that due to some bug were
locked at 312 MHz force a speedo ID of 2 for now which allows regular
operation of up to 1.4 GHz (single core only).
|
|
I211 with a blank iNVM uses a different PCI ID. Hack the driver to load
despite i211 data sheet claiming tools only, not for driver.
Please note that the existing driver hacks concerning NVM validation
skipping and Ethernet MAC address assignment equally apply.
Tested on initial samples of Apalis T30 1GB V1.0A.

|
Allow for jumper-less ACM operation by defaulting to 0x20 I2C address.
|
|
Enable the modular camera configuration for ACM which allows switching
not only decoders but also their inputs at run-time.
This is the only correct order to load the modules:
modprobe videobuf2-memops
modprobe videobuf2-dma-nvmap
modprobe max9526
# or modprobe adv7180
modprobe tegra_v4l2_camera
To change the decoder on the fly:
rmmod tegra_v4l2_camera
rmmod max9526
# or rmmod adv7180
modprobe adv7180
# or modprobe max9526
modprobe tegra_v4l2_camera
To get a pre-view window through gstreamer:
gst-launch v4l2src ! deinterlace tff=1 method=4 ! nv_omx_videomixer !
nv_gl_eglimagesink
To switch inputs (0-5 resp. 0-4 for ADV7180 and 0-2 for MAX9526 where 2
means auto selection):
v4l2-ctl -i 0
v4l2-ctl -i 1
v4l2-ctl -i 2
v4l2-ctl -i 3
v4l2-ctl -i 4
v4l2-ctl -i 5
To check what input is active:
v4l2-ctl -I
While at it enable NVIDIA confirmed ARM errata 716044 and 720789 as
well.
|
|
Re-work input selection to apply to a live camera stream.
While at it default to automatic input selection and make this option
available via IOCTL as input value 2 as well.
|
|
Re-work input selection to apply to a live camera stream.
While at it disable the automatic I2C module loading for now as due to
our currently redundant soc-camera-pdrv registration via board specific
platform data the adv7180 driver is always automatically loaded upon
modprobe tegra_v4l2_camera invocation.

This patch fixes building without CONFIG_SATA_AHCI_TEGRA aka SATA
support which previously failed as follows:

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.

Hack to avoid 24 Hz mode in X resulting in no display at all. This has

Enable PCI quirk support resp. don't explicitly disable it in order for
the following fix to take effect.
The Apalis evaluation board needs to set the link speed to 2.5 GT/s
(GEN1). The default link speed setting is 5 GT/s (GEN2). 0x98 is the
Link Control 2 PCIe Capability Register of the PEX8605 PCIe switch. The
switch supports link speed auto negotiation, but falsely sets the link
speed to 5 GT/s.

Previously only 64-lead and 40-lead models were identified. This patch
adds 48-lead and 32-lead device identification as well.
Please note that due to missing parameter negotiation functions one
might get the following message with a subsequent crash:
WARNING: from element /GstPipeline:pipeline0/GstV4l2Src:v4l2src0: Could
not get parameters on device '/dev/video0'
This can be avoided by explicitly specifying the format as follows:
gst-launch v4l2src ! deinterlace tff=1 method=4 ! 'video/x-raw-yuv,
width=(int)720, height=(int)576, format=(fourcc)I420' !
nv_omx_videomixer ! nv_gl_eglimagesink
