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.
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
Verify standard GPIO usage for latest v1.1a samples. While at it get rid of some commented out obsolete stuff.
2012-12-04colibri_t30: USB: integrate Ethernet initialisationMarcel 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.
2012-11-27colibri_t30: WIRELESS_EXT hackMarcel Ziswiler
Hack to force WIRELESS_EXT required to build Redpine Signals LiteFi driver.
2012-11-27colibri_t30: enable USB audioMarcel Ziswiler
Enable kernel configuration for USB audio.
2012-11-27colibri_t30: USB: 2 mA VBUS drawMarcel Ziswiler
As Colibris are usually self powered default drawn VBUS to 2 mA rather than demanding 500 mA. This should fix it running from not self powered USB hubs as well.
2012-11-27colibri_t30: activate Android gadgetMarcel Ziswiler
Activate Android rather than mass storage gadget driver to support multiple USB functions. The functions can be configured via a board file and may be enabled and disabled dynamically. E.g. the following enables regular Ethernet aka RNDIS functionality once booted: echo rndis > /sys/class/android_usb/android0/functions echo 1 > /sys/class/android_usb/android0/enable
2012-11-27colibri_t30: usb: activate colibri otg driverMarcel Ziswiler
Activate Colibri rather than Tegra USB OTG driver as used on Colibri T20 as well.
2012-11-27colibri_t30: usb: integrate otg functionalityMarcel Ziswiler
Integrate USB OTG functionality similar to Colibri T20.
2012-11-27colibri_t30: comment, indentation and white space clean-upMarcel Ziswiler
Clean up various comments, indentation and white space issues.
2012-11-27tegra: usb: kernel configurationMarcel Ziswiler
Get rid of duplicate USB EHCI ULPI VIEWPORT stuff in Kconfig.
2012-11-27tegra: fix file names and paths in commentsMarcel Ziswiler
Several file names and paths showed copy/paste or otherwise issues.
2012-11-26colibri_pxa: add default configurationMarcel Ziswiler
Add default kernel configuration in order to run oe-core on any of the Colibri PXA series modules. So far no further platform data additions have been committed meaning only older PXA270 v1.x, PXA300/310 v1.x or PXA320 v1.x modules as anyway supported in mainline will work.
2012-11-26colibri_pxa: fix pwm availabilityMarcel Ziswiler
So far only Income's board advertised PWM availability but of course any Colibri is potentially PWM capable.
2012-11-26colibri_pxa270: fix evalboard mmc/sd card detectMarcel Ziswiler
Due to a missing else if always the GPIO number as on colibri_pxa320 was being used which of course failed card detection.
2012-11-26ARM: 7115/4: move __exception and friends to asm/exception.hJamie Iles
The definition of __exception_irq_entry for CONFIG_FUNCTION_GRAPH_TRACER=y needs linux/ftrace.h, but this creates a circular dependency with it's current home in asm/system.h. Create asm/exception.h and update all current users. v4: - rebase to rmk/for-next v3: - remove redundant includes of linux/ftrace.h v2: - document the usage restricitions of __exception* Cc: Zoltan Devai <zdevai@gmail.com> Signed-off-by: Jamie Iles <jamie@jamieiles.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-11-26arm: mm: fix pageattr build if not v7Marcel Ziswiler
As pageattr.c gets built unconditionally it fails linking on none v7 arms (e.g. PXA) with the following error message: arch/arm/mm/pageattr.c:38: undefined reference to `v7_flush_kern_cache_all'
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.
2012-11-20colibri_t20: USB: 2 mA VBUS drawMarcel Ziswiler
As Colibris are usually self powered default drawn VBUS to 2 mA rather than demanding 500 mA. This should fix it running from not self powered USB hubs as well.
2012-11-19colibri_t20: activate Android gadgetMarcel Ziswiler
Activate Android rather than Ethernet gadget driver to support multiple USB functions. The functions can be configured via a board file and may be enabled and disabled dynamically. E.g. the following enables regular Ethernet aka RNDIS functionality once booted: echo rndis > /sys/class/android_usb/android0/functions echo 1 > /sys/class/android_usb/android0/enable
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.
2012-11-12Merge branch 'l4t/l4t-r16-r2' into colibriMarcel Ziswiler
