3.3V consumers
|
|
PLLE: now supplied by LDO6 - Put the limits of the supplied circuit as constraints - Moved derived rails from 1.8V to 3.3V where applicable
|

Looks like we mixed up the low-active buffer enable GPIOs. This fixes
GMI_WR_N on SODIMM pin 93 RDnWR curtsey Tord Andersson from Endian
Technologies AB.

|
After having registered the following proper machine type migrate to
actually using it.

Well commit bfd8d6dc27ccf00bf89b0a7bb3d359bab2142376 got rid of the w1
include a little prematurely.
|
|
Add one-wire platform data. Still requires explicitly enabling the
following two kernel configuration options:
CONFIG_W1
CONFIG_W1_MASTER_TEGRA
|
|
Make PWM B, C, D accessible from userspace. e.g as
/sys/class/leds/pwm_b.
|
|
Can be initiated both by LXDE Logout - Suspend or manually doing
'echo mem > /sys/power/state'. Uses GPIO key power (SODIMM pin 45,
Iris X16-20) as wake-up source. If woken-up LXDE session does not
automatically activate desktop again try manually doing a 'chvt 7'.
|
|
Implement the following GPIO keys:
- find (SODIMM pin 77)
- home (SODIMM pin 127)
- back (SODIMM pin 133, Iris X16-14)
- volume up (SODIMM pin 22)
- volume down (SODIMM pin 24)
- power (SODIMM pin 45, Iris X16-20)
- menu (SODIMM pin 135)

Now simply enabling CONFIG_TEGRA_CAMERA resp. not explicitly disabling
it will make L4T's nv_omx_vip Gstreamer plug-in work with analogue video
decoders like the ADV7180 or MAX9526.
|
|
Booting with a bare USB hub (e.g. EvalBoard V3.1A) and later plugging
in a USB device completely hang the system. This fixes it.
|
|
Shorten GPL license header.
Get rid of obsolete includes.
Get rid of spurious comments.
Fix indentation.
Add some clarifying comments.

As our hardware only allows triggering an interrupt on over-temperature
shutdown we setup a workqueue to catch leaving it again.
For Tegra 3 NVIDIA relies on the regular Linux thermal subsystem.
As follows some output during a thermal throttling run:

Adjust thermal throttling to latest lm95245 evolution and wait with the
interrupt registration until we get the LM95245 drivers probe callback.
While at it add some clarifying comments and wrap RTC stuff with a
define.
|
|
In order to allow tighter integration with external thermal throttling
code add local temperature and remote critical shutdown temperature
hooks. Rename the existing hooks for clarity.
|
|
Our platform data erroneously used the forth (bus number 3) rather than
the first (bus number 0) controller instance.
|
|
Get rid of obsolete NAND aka Colibri T30 v1.0a prototype handling.
|
|
Add BERR counter functionality to MCP251x driver.

As our hardware only allows triggering an interrupt on over-temperature
shutdown we first use it to catch entering throttle limit and only then
set it up to catch an actual over-temperature shutdown.
While throttling we setup a workqueue to catch leaving it again.
We support the same sysfs interface as on NVIDIA Ventana:

In order to allow integrating with external thermal throttling code add
a probe callback and remote over-temperature shutdown hooks.
|
|
Integrate remote over-temperature shutdown ROS pin handling.
|
|
Clean-up I2C platform data and bring it more in line with Colibri T30.
|
|
In addition to the critical temperature alarm limit this chip features
a second alarm limit called remote over-temperature shutdown ROS with
a separate pin configurable as trigger output. Implement this feature
and add platform data to allow configuring respective pin as output.
|
|
Rather than using hard-coded register indices and offsets define and
use an enumeration thereof.

Avoid the following issue on both /dev/ttyHS1 as well as /dev/ttyHS3:

|
|
Integrate spidev support straight from Colibri T20.
|
|
Instead of copying the boot loader frame buffer which currently neither
displays anything worth preserving nor even what it has in the right
resolution make sure both LVDS as well as HDMI frame buffers get
cleared during initialisation to avoid displaying random garbled stuff.

Add the following tested (e.g. framebuffer console and X) video modes:
- 1280x1024@60
- 1600x1200@60
- 1680x1050@60
- 1920x1080p
- 1920x1200
And the following portrait modes:
- 480x640
- 540x960
- 720x1280
The define TEGRA_FB_VGA in board-colibri_t20.h can be used to switch
between VGA and 800x480.
While at it clean-up some defines and includes.
|
|
Clean-up I2C platform data.
|

Validate pin-muxing for latest Colibri T30 v1.1a and v1.1b module
hardware.

The irq request flag sometimes does not get reset or is asserted
immediately, but iir does not indicated this, if so ISR is entered with
iir set to 0xc1, i.e. no irq pending.
Try enabling the transmit register empty interrupt, iir becomes 0xc2,
irq gets de-asserted and ier is reverted by the regular code flow in
the ISR.
We try this every 4096 spurious irq.

As the new Colibri Evaluation carrier board v3.1a uses SODIMM pin 45 as
IrDA transceiver SD with a 100 K pull-down we revert to using the power
key as high active.
|
|
GPIO keys configured as active-low either require pull-ups on the
carrier board or via pin-muxing. We enable the later for now.
|
|
Use GPIO inputs for function tri-stating rather than pin group
tri-stating to avoid influencing neighbouring pins.
While at it get rid of most pull-up/downs and a lot of commented out
stuff.
|
|
Rename CAMERA_INTERFACE to COLIBRI_T20_VI which stands for video input
to be more in-line with Colibri T30.
|
|
Get rid of optional CAM/GEN3_I2C on SODIMM pin 127/133.
|
|
Verify standard GPIO usage for latest v1.2a modules.
|
|
The Iris carrier board by default uses SODIMM pin 73 as DAC power save.
Note: This conflicts with the CAN interrupt on the new EvalBoard v3.1a.
|
|
VESA VGA mode defines hsync/vsync to be of polarity low rather than
high.
|
|
The HDMI power rail configuration used to be done within the LVDS aka
TFTLCD panel enable function. Now moving it to the platform power
initialisation where it really belongs. This avoids any
duplicate/spurious regulator configuration.
|
|
As the deep-sleep LP0 suspend mode is currently anyway not supported
default to the LP1 suspend mode for now.
|
|
The full PMIC power off decreases power consumption but doing a
subsequent reset won't force a re-boot any more.
|
|
Clean-up the following unused regulator supplies in the platform power
stuff:
p_cam_avdd, avdd_lvds, vddio_sys (panjit_touch), vmmc (sdhci-tegra.3)
and avdd_2v85.
While at it add some more comments concerning specific consumers/rails.
