2013-01-11colibri_t30: fix system hang caused by USB device insertionMarcel Ziswiler
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.
2013-01-11colibri_t30: clean-up board fileMarcel Ziswiler
Shorten GPL license header. Get rid of obsolete includes. Get rid of spurious comments. Fix indentation. Add some clarifying comments.
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
2013-01-08colibri_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.

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

2012-11-27colibri_t30: comment, indentation and white space clean-upMarcel Ziswiler

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.
