2013-01-09colibri_t30: integrate thermal throttlingMarcel Ziswiler
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.

2013-01-09colibri_t20: adjust thermal throttlingMarcel Ziswiler
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.
2013-01-08colibri_t30: fix SPIMarcel Ziswiler
Our platform data erroneously used the forth (bus number 3) rather than the first (bus number 0) controller instance.
2013-01-08colibri_t30: get rid of obsolete NAND handlingMarcel Ziswiler
Get rid of obsolete NAND aka Colibri T30 v1.0a prototype handling.
2013-01-07colibri_t20: integrate thermal throttlingMarcel Ziswiler
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: root@colibri-t20:~# cat /sys/kernel/debug/thermal/shutdown 115000 root@colibri-t20:~# cat /sys/kernel/debug/thermal/throttle 90000 As follows some output of before and during a throttling run: root@colibri-t20:~# tegrastats RAM 159/345MB (lfb 36x4MB) Carveout 11/128MB (lfb 116MB) GART 0/32MB (lfb 32MB) IRAM 4/255kB(lfb 248kB) cpu [51%,23%]@216 EMC 666 AVP 72 VDE 240 EDP limit -1 Temperatures CPU 48.7 Board 43.2 root@colibri-t20:~# cat /sys/devices/system/cpu/cpu0/cpufreq/throttle 0 root@colibri-t20:~# cat /sys/bus/i2c/devices/4-004c/temp2_os 90000 root@colibri-t20:~# cat /sys/kernel/debug/thermal/shutdown 115000 root@colibri-t20:~# cat /sys/kernel/debug/thermal/throttle 90000 root@colibri-t20:~# tegrastats RAM 66/345MB (lfb 5x32kB) Carveout 75/128MB (lfb 53MB) GART 8/32MB (lfb 24MB) IRAM 20/255kB(lfb 232kB) cpu [85%,83%]@912 EMC 666 AVP 216 VDE 240 EDP limit -1 Temperatures CPU 90.1 Board 77.9 root@colibri-t20:~# cat /sys/devices/system/cpu/cpu0/cpufreq/throttle 1 root@colibri-t20:~# cat /sys/bus/i2c/devices/4-004c/temp2_os 115000

Integrate spidev support straight from Colibri T20.
2012-12-21colibri_t30: clear LVDS/HDMI framebuffersMarcel Ziswiler
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.
2012-12-21tegra: colibri_t30: add more video modesMarcel Ziswiler
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.
2012-12-21colibri_t30: i2c: clean-upMarcel Ziswiler
Clean-up I2C platform data.

2012-12-17tegra: colibri_t20: add more video modesT20_LinuxImageV2.0Beta1_20121218Marcel Ziswiler
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 fix rename of CAMERA_INTERFACE to COLIBRI_T20_VI as well.
2012-12-17colibri_t20: fix power key on EvalBoard v3.1aMarcel Ziswiler
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.
2012-12-17colibri_t20: gpio-keys: enable pull-upsMarcel Ziswiler
GPIO keys configured as active-low either require pull-ups on the carrier board or via pin-muxing. We enable the later for now.
2012-12-17colibri_t20: pin-mux: re-work function tri-statingMarcel Ziswiler
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.
2012-12-17colibri_t20: camera: rename CAMERA_INTERFACE defineMarcel Ziswiler
Rename CAMERA_INTERFACE to COLIBRI_T20_VI which stands for video input to be more in-line with Colibri T30.
2012-12-17colibri_t20: I2C: remove optional CAM/GEN3_I2CMarcel Ziswiler
Get rid of optional CAM/GEN3_I2C on SODIMM pin 127/133.
2012-12-17colibri_t20: GPIO: re-work GPIO usageMarcel Ziswiler
Verify standard GPIO usage for latest v1.2a modules.
2012-12-12colibri_t20: implement DAC power save for Iris carrier boardMarcel Ziswiler
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.
2012-12-12colibri_t20: fix hsync/vsync polarity for default VESA VGAMarcel Ziswiler
VESA VGA mode defines hsync/vsync to be of polarity low rather than high.
2012-12-12colibri_t20: move HDMI power rail configurationMarcel Ziswiler
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.
2012-12-12colibri_t20: default to LP1 suspendMarcel Ziswiler
As the deep-sleep LP0 suspend mode is currently anyway not supported default to the LP1 suspend mode for now.
2012-12-12colibri_t20: use full PMIC power offMarcel Ziswiler
The full PMIC power off decreases power consumption but doing a subsequent reset won't force a re-boot any more.
2012-12-12colibri_t20: clean-up platform power stuffMarcel Ziswiler
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.
2012-12-12colibri_t20: clear LVDS/HDMI framebuffersMarcel Ziswiler
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.
2012-12-12colibri_t20: fix too much tux issueMarcel Ziswiler
The boot logo and framebuffer console where displayed with a wrong stride caused by a colour depth mismatch. Fix this by initially configuring the display controllers to 16 bpp.
2012-12-12colibri_t20: enable userspace regulator consumer supportMarcel Ziswiler
There are some classes of devices that are controlled entirely from user space. Userspace consumer driver provides ability to control power supplies for such devices. Enable this configuration option to be more in line with the T30.
2012-12-12colibri_t20: enable forcing console flush on restartMarcel Ziswiler
If the console is locked while the system is rebooted, the messages in the temporary log buffer would not have propagated to all the console drivers. This option forces the console lock to be released if it failed to be acquired, which will cause all the pending messages to be flushed. Enable this configuration option to be more in line with the T30.
2012-12-12colibri_t20: use default 3G/1G virtual user/kernel memory splitMarcel Ziswiler
Get rid of the 2G/2G user/kernel memory split configuration in order to use the default 3G/1G user/kernel memory split. This is more in line with the T30 and avoids issues trying to run Android.
2012-12-05colibri_t30: MMC: fix SDMMC4B pinmuxMarcel Ziswiler
Fix two issues concerning SDMMC4B pinmux (e.g. using a regular SD card as the boot device instead of the on-module eMMC). First according to the TRM it is illegal to mux a certain function to two sets of balls (e.g. the regular SDMMC4 as well as the SDMMC4B muxing). Second make absolutely sure all unused balls are not only tri-stating their outputs but also disable their inputs to prevent any illegal internal states.
