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. As follows some output during a thermal throttling run: root@colibri-t30:~# cat /sys/bus/i2c/devices/4-004c/temp2_os 45000 RAM 400/980MB (lfb 135x4MB) IRAM 0/255kB(lfb 255kB) cpu [12%,2%,3%,6%]@475 EMC 533 AVP 81 VDE 400 EDP limit 1300000 Temperatures CPU 42.4 Board 36.4 root@colibri-t30:~# cat /sys/bus/i2c/devices/4-004c/temp2_os 60000 RAM 400/980MB (lfb 135x4MB) IRAM 0/255kB(lfb 255kB) cpu [14%,5%,4%,4%]@1300 EMC 533 AVP 81 VDE 400 EDP limit 1300000 Temperatures CPU 54.2 Board 47.8 RAM 400/980MB (lfb 135x4MB) IRAM 0/255kB(lfb 255kB) cpu [100%,100%,100%,100%]@1200 EMC 533 AVP 81 VDE 400 EDP limit 1200000 Temperatures CPU 70.4 Board 56.6 root@colibri-t30:~# cat /sys/bus/i2c/devices/4-004c/temp2_os 75000 RAM 400/980MB (lfb 135x4MB) IRAM 0/255kB(lfb 255kB) cpu [54%,49%,48%,48%]@1200 EMC 533 AVP 81 VDE 400 EDP limit 1200000 Temperatures CPU 70.9 Board 57.1 RAM 400/980MB (lfb 135x4MB) IRAM 0/255kB(lfb 255kB) cpu [100%,100%,100%,100%]@1100 EMC 533 AVP 81 VDE 400 EDP limit 1100000 Temperatures CPU 75.3 Board 60.5 root@colibri-t30:~# cat /sys/bus/i2c/devices/4-004c/temp2_os 85000 RAM 401/980MB (lfb 135x4MB) IRAM 0/255kB(lfb 255kB) cpu [65%,61%,61%,61%]@1100 EMC 533 AVP 81 VDE 400 EDP limit 1100000 Temperatures CPU 75.2 Board 61.0 RAM 401/980MB (lfb 135x4MB) IRAM 0/255kB(lfb 255kB) cpu [100%,100%,100%,100%]@1000 EMC 533 AVP 81 VDE 400 EDP limit 1100000 Temperatures CPU 85.1 Board 69.8 RAM 401/980MB (lfb 135x4MB) IRAM 0/255kB(lfb 255kB) cpu [100%,100%,100%,100%]@760 EMC 533 AVP 81 VDE 400 EDP limit 1100000 Temperatures CPU 85.1 Board 69.9 root@colibri-t30:~# cat /sys/class/thermal/cooling_device0/cur_state 0 root@colibri-t30:~# cat /sys/class/thermal/cooling_device0/max_state 10 root@colibri-t30:~# cat /sys/class/thermal/cooling_device0/type balanced root@colibri-t30:~# cat /sys/class/thermal/thermal_zone0/cdev0_trip_point 0 root@colibri-t30:~# cat /sys/class/thermal/thermal_zone0/temp 84531 root@colibri-t30:~# cat /sys/class/thermal/thermal_zone0/trip_point_0_temp 85000 root@colibri-t30:~# cat /sys/class/thermal/thermal_zone0/trip_point_0_type passive root@colibri-t30:~# cat /sys/class/thermal/thermal_zone0/type lm95245_remote
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.

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

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

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.
2012-12-05colibri_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.
2012-12-05colibri_t30: fix pinmuxing for NC ballsMarcel Ziswiler
Make sure NC balls are not only tri-stating their outputs but also do not drive their inputs but rather have them pulled down in order to prevent any unstable internal values. While at it fix alphabetical order of the pinmuxes.
2012-12-05colibri_t30: MMC: fix building for SDMMC4BMarcel Ziswiler
This fixes the following build issue: arch/arm/mach-tegra/board-colibri_t30.c:276:41: error: 'colibri_t30_emmc_platform_data' defined but not used [-Werror=unused-variable] cc1: all warnings being treated as errors
2012-12-04colibri_t30: GPIO: re-work GPIO usageMarcel Ziswiler

Integrate proper Ethernet initialisation analogous to how it is done for the Colibri T20.
2012-12-04colibri_t30: NAND: disable NAND on post v1.0a modulesMarcel Ziswiler
Add a commented out define for v1.0a modules with optional NAND variants which are auto detected.
2012-12-04colibri_t30: MMC/NAND: fix eMMC vs. NAND detectionMarcel Ziswiler
As we don't want to exclusively reserve the detection GPIO temporarily enabling it is still required.

2012-11-21colibri_t30: hack to fix eMMC detectionMarcel Ziswiler
Looks like this DPD stuff whatever it is fails eMMC detection on our current Colibri T30 prototypes. See f4cd0d4448d65a42b65c338f85a3ab8064923c61.
2012-11-16android: dc: tegra: video: conditionally revert timestamp supportMarcel Ziswiler
Android R14 userspace seems to have issues with timestamp support: [ 14.764337] host1x host1x: SurfaceFlinger: syncpoint id 8 (disp0_a) stuck waiting 3, timeout=2147483447 [ 14.773845] host1x host1x: id 8 (disp0_a) min 2 max 4 [ 14.779163] host1x host1x: id 9 (disp1_a) min 2 max 4 [ 14.784316] host1x host1x: id 18 (2d_0) min 21 max 25 [ 14.789586] host1x host1x: id 20 (disp0_b) min 2 max 4 [ 14.794889] host1x host1x: id 21 (disp1_b) min 2 max 4 [ 14.800241] host1x host1x: id 22 (3d) min 77 max 95 [ 14.805217] host1x host1x: id 24 (disp0_c) min 2 max 4 [ 14.810573] host1x host1x: id 25 (disp1_c) min 2 max 4 [ 14.815873] host1x host1x: id 26 (vblank0) min 800 max 0 [ 14.821264] host1x host1x: id 27 (vblank1) min 684 max 0 [ 14.826810] host1x host1x: waitbase id 3 val 77 Therefore conditionally revert it in that case for now. See e4e2e776a3d4bf1adf37fc061cfdfb92281f3ace.
2012-11-15colibri_t30: add DT boot supportMarcel Ziswiler
Use the existing boardfile for everything, just match using DT. See df80522dd557e2759552b6c6b0f1f1c8ad1c5614.
2012-11-15colibri_t30: integration of i2s slave mode supportMarcel Ziswiler
Add configurability support for i2s parameters. See 907bac80691c7df5b5b57cbf27f91e8bb1dcf434.
2012-11-15colibri_t30: sd: enable sd dpdMarcel Ziswiler
This is a WAR solution that allows for the turning on SD DPD feature. The original issue is that enabling SD DPD immediately after device comes out of LP0 causes ULPI disconnect. The root cause of that is not known. The WAR is to delay the enabling of SD DPD for 100ms after device comes out of LP0. While at it remove commented out tegra_reserve stuff. See 5e07056dc8b922b8b43a01b60a949c1dda75d9a9.
2012-11-14colibri_t20: add device tree supportMarcel Ziswiler
Enable device tree support for Colibri T20 by adding board compatible table. See 293b009a282e1508a4947d84463fdfe820445a50.
2012-11-14colibri_t20: do not power off USB phy in suspendMarcel Ziswiler
Since there is no PMC available in tegra2 we will not be able to get any remote wakeup events. Hence do not power of the phy during usb suspend. See c4a5c51e493a8d4154c15c95d2bd93b348090892.
2012-11-14colibri_t20: fix keyboard GPIO resp. GPIO K6Marcel Ziswiler
SODIMM pin 135 is really GPIO K6 multiplexed with ACC1_DETECT. Unfortunately the later can't be tri-stated but since it is anyway always an input it should not interfere. Please note however that this SODIMM pin is rather low resistance.

2012-11-12colibri_t20: add emc table for 256 MB versionMarcel Ziswiler
Add emc table for 256 MB module version. Assume less than 256 MB of kernel memory (e.g. physical memory minus carveout and framebuffers) means we are running on a 256 MB module.
2012-11-12colibri_t20: GPIO keys implementation for AndroidMarcel Ziswiler
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)
