* config: don't define CONFIG_ARCH_DEVICE_TREEStephen Warren2013-08-02-10/+0
| | | | | | | Now that nothing uses CONFIG_ARCH_DEVICE_TREE, stop defining it. Signed-off-by: Stephen Warren <swarren@nvidia.com> Acked-by: Simon Glass <sjg@chromium.org>

* tegra: usb: move implementation into right directoryLucas Stach2013-03-14-556/+0
| | | | | | | | | | | | | | | | This moves the Tegra USB implementation into the drivers/usb/host directory. Note that this merges the old /arch/arm/cpu/armv7/tegra20/usb.c file into ehci-tegra.c. No code changes, just moving stuff around. v2: While at it also move some defines and the usb.h header file to make usb driver usable for Tegra30. NOTE: A lot more work is required to properly init the PHYs and PLL_U on Tegra30, this is just to make porting easier and it does no harm here.

* tegra: usb: various small cleanupsLucas Stach2013-03-14-12/+1
| | | | | | | | | Remove unneeded headers, function prototype and stale comment, that doesn't match the actual codebase anymore. Signed-off-by: Lucas Stach <dev@lynxeye.de> Acked-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>
* tegra: usb: move controller init into start_portLucas Stach2013-03-14-28/+29
| | | | | | | | | | | There is no need to init a USB controller before the upper layers indicate that they are actually going to use it. board_usb_init now only parses the device tree and sets up the common pll.

* tegra: usb: make controller init functions more self containedLucas Stach2013-03-14-12/+12
| | | | | | | | | | | | | There is no need to pass around all those parameters. The init functions are able to easily extract all the needed setup info on their own. This allows to move out the controller init into ehci_hcd_init later on, without having to save away global state for later use and thus bloating the file global state.

* tegra: Add SOC support for display/lcdWei Ni2012-11-19-0/+410
| | | | | | | | | | | | | | Add support for the LCD peripheral at the Tegra2 SOC level. A separate LCD driver will use this functionality to configure the display.

| | | | | | | | The pulse width/frequency modulation peripheral supports generating a repeating pulse. It is useful for controlling LCD brightness. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>
* Tegra20: Move some include files to arch-tegra for sharing with Tegra30Tom Warren2012-10-15-4/+4
| | | | | | | | | | | The move is pretty straight-forward. ap20.h and tegra20.h were renamed to ap.h and tegra.h. Some files remain in arch-tegra20 but 'include' a file in 'arch-tegra' with #defines & structs that will be common between T20 and T30 HW. HW-specific #defines, etc. stay in the 'arch-tegra20' 'root' file. All boards build OK w/MAKEALL -s tegra20. Checkpatch.pl runs clean. Seaboard works OK.

* Tegra20: Move some code files to common directories for upcoming Tegra30 ↵Tom Warren2012-10-15-66/+0
| | | | | | | | | | | | | | | | patches. Move files that are going to be common between T20 and T30 into 'tegra-common' subdirs in AVP (arm720t), CPU (armv7), and shared (arch/arm/cpu/.) areas. Any files that are left behind in '/tegra20' will be copied to '/tegra30' subdirs and modified for that SoC. The 'common' files should need only minor changes. Include files (arch/arm/include/asm/arch-tegra/tegra20) will be done in a follow-on patch. Builds fine w/MAKEALL -s tegra20. Checkpatch.pl is clean. Signed-off-by: Tom Warren <twarren@nvidia.com>
* tegra20: add USB ULPI init codeLucas Stach2012-10-15-22/+131
| | | | | | | | | | | | | This adds the required code to set up a ULPI USB port. It is mostly a port of the Linux ULPI setup code with some tweaks added for more correctness, discovered along the way of debugging this. To use this both CONFIG_USB_ULPI and CONFIG_USB_ULPI_VIEWPORT have to be set in the board configuration file.

* tegra20: port to new ehci interfaceLucas Stach2012-10-15-11/+4

* Tegra: Change Tegra20 to Tegra in common code, prep for T30Tom Warren2012-09-10-1/+1
| | | | | | | | | | Convert TEGRA20_ defines to either TEGRA_ or NV_PA_ where appropriate. Convert tegra20_ source file and function names to tegra_, also. Upcoming Tegra30 port will use common code/defines/names where possible. Signed-off-by: Tom Warren <twarren@nvidia.com> Acked-by: Stephen Warren <swarren@nvidia.com>

* tegra20: Remove armv4t build flagsAllen Martin2012-09-01-12/+0
| | | | | | | | | | | These flags were necessary when building tegra20 as a single binary that supported ARM7TDMI and Cortex A9. Now that the ARM7TDMI support is split into a separate SPL, this is no longer necessary.
