2014-03-05ARM: tegra: move CONFIG_TEGRAnnStephen Warren
<asm/arch-tegra/tegra.h> needs to use CONFIG_TEGRA* to conditionalize some definitions, since some modules moved between generations. Move the definition of CONFIG_TEGRAnn to a header that's included earlier, so that it's set by the time tegra.h needs to use it.

2013-07-11ARM: Tegra: USB: EHCI: Add support for Tegra30/Tegra114Jim Lin
Tegra30 and Tegra114 are compatible except PLL parameters. Tested on Tegra30 Cardhu, and Tegra114 Dalmore platforms. All works well. Signed-off-by: Jim Lin <jilin@nvidia.com> Signed-off-by: Tom Warren <twarren@nvidia.com>
2013-03-25spi: add common fdt SPI driver interfaceAllen Martin
Add a common interface to fdt based SPI drivers. Each driver is represented by a table entry in fdt_spi_drivers[]. If there are multiple SPI drivers in the table, the first driver to return success from spi_init() will be registered as the SPI driver.

2013-03-25tegra: spi: pull register structs out of headersAllen Martin
Move register structs from headers into .c files and use common name. This is in preparation of making common fdt front end for SPI drivers. Signed-off-by: Allen Martin <amartin@nvidia.com> Signed-off-by: Tom Warren <twarren@nvidia.com> Reviewed-by: Stephen Warren <swarren@nvidia.com>

2013-03-25tegra: remove support for UART SPI switchAllen Martin
This feature was only used for tegra20 seaboard that had a pinmux conflict on the SPI pins. These boards were never manufactured, so remove this support to clean up SPI driver.

2013-03-14tegra: usb: move implementation into right directoryLucas Stach
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.

2013-02-11tegra: rename FUNCMUX_UART2_UARTBStephen Warren
FUNCMUX_ defines should be named after the pin groups they affect, not after the module they're muxing onto those pin groups. Signed-off-by: Stephen Warren <swarren@nvidia.com> Acked-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>
2013-02-11Tegra: Move common clock code to arch/arm/cpu/tegra-common/clock.cTom Warren
This 'commonizes' much of the clock/pll code. SoC-dependent code and tables are left in arch/cpu/tegraXXX-common/clock.c Some T30 tables needed whitespace fixes due to checkpatch complaints. Signed-off-by: Tom Warren <twarren@nvidia.com>
2013-01-16tegra: remove IRDA pinmux synonymAllen Martin
IRDA is a synonym for UARTB in tegra pinmux, remove all usage of this synonym and replace with UARTB to disambiguate. Signed-off-by: Allen Martin <amartin@nvidia.com> Reviewed-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Tom Warren <twarren@nvidia.com>
2013-01-16Tegra30: Add arch-tegra30 include filesTom Warren
Common Tegra files are in arch-tegra, shared between T20 and T30. Tegra30-specific headers are in arch-tegra30. Note that some of these will be filled in as more T30 support is added (drivers, WB/LP0 support, etc.). A couple of Tegra20 files were changed to support common headers in arch-tegra, also.

2012-10-29tegra: move to common SPL frameworkAllen Martin
Change tegra SPL to use common SPL framework. Any tegra specific initialization is now done in spl_board_init() instead of board_init_f()/board_init_r(). Only one SPL boot target is supported on tegra, which is boot to RAM image. jump_to_image_no_args() must be overridden on tegra so the host CPU can be initialized.

2012-10-15tegra20: add clock_set_pllout functionLucas Stach
Common practice on Tegra 2 boards is to use the pllp_out4 FO to generate the ULPI reference clock. For this to work we have to override the default hardware generated output divider. This function adds a clean way to do so. Signed-off-by: Lucas Stach <dev@lynxeye.de> Signed-off-by: Tom Warren <twarren@nvidia.com>
2012-10-15tegra20: complete periph_id enumLucas Stach

2012-10-15Tegra20: Move some include files to arch-tegra for sharing with Tegra30Tom Warren
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.

2012-10-15tegra20: add USB ULPI init codeLucas Stach
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.

2012-09-01ARM: add tegra20 support to arm720tAllen Martin
Add support for tegra20 arm7 boot processor. This processor is used to power on the Cortex A9 and transfer control to it. In tegra this processor is an ARM7TDMI not an ARM720T, but since we don't use cache it was easier to just reuse the ARM720T code as the processors are otherwise identical except for cache and MMU.
