2012-07-09tegra: fix leftover CONFIG_TEGRA2_MMC & _SPI build switchesTom Warren
Missed some boards after my tegra2_mmc.* -> tegra_mmc.* change, and one instance of CONFIG_TEGRA2_SPI. MAKEALL -s tegra2 AOK, Seaboard MMC AOK. Didn't test Tamonten, Paz00 or TrimSlice, as I have none here. Signed-off-by: Tom Warren <twarren@nvidia.com> Acked-by: Stephen Warren <swarren@wwwdotorg.org>

2012-07-07spi: tegra2: rename tegra2_spi.* to tegra_spi.*Tom Warren
In anticipation of Tegra3 support, start removing/renaming Tegra2-specific files. No functional changes (yet). Also updated copyright to 2012. Signed-off-by: Tom Warren <twarren@nvidia.com>
2012-07-07spi: Tegra2: Seaboard: fix UART corruption during SPI transactionsTom Warren
Simon Glass's proposal to fix this on Seaboard was NAK'd, so I removed his NS16550 references and added a small delay before SPI/UART muxing. Tested on my Seaboard with large SPI reads/writes and saw no corruption (crc's matched) and no spurious comm chars.

2012-05-15tegra: Turn off power detect in board initWei Ni
Tegra core power rail has leakage voltage around 0.2V while system in suspend mode. The source of the leakage should be coming from PMC power detect logic for IO rails power detection. That can be disabled by writing a '0' to PWR_DET_LATCH followed by writing '0' to PWR_DET (APBDEV_PMC_PWR_DET_0).

2011-12-24tegra: Move clock_early_init() to arch_cpu_init()Simon Glass

2011-12-24tegra: Move cpu_init_cp15() to arch_cpu_init()Simon Glass
This call is more of an architecture requirement than a board one, so move it there. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Tom Warren <twarren@nvidia.com>
2011-12-24tegra2: Move tegra2_mmc_init() prototype to public header.Thierry Reding
tegra2_mmc_init() is implemented by the Tegra2 MMC driver. Since most of the Tegra2-based boards will need to call it, this commit exports it in the new public asm/arch/mmc.h header file to prevent each board from providing its own prototype.

2011-12-24tegra2: Plumb in SPI/UART switch codeSimon Glass
On Seaboard the UART and SPI interfere with each other. This causes the UART to receive spurious zero bytes after SPI transactions and also means that SPI can corrupt a few output characters when it starts up if they are still in the UART buffer. This updates the board to use the SPI/UART switch to avoid the problem. For now this feature is turned off since it needs changes to the NS16550 UART to operate.

2011-12-24tegra2: Implement SPI / UART GPIO switchSimon Glass
The Tegra2 Seaboard has the unfortunate feature that SPI and the console UART are multiplexed on the same pins. We need to switch between one and the other during SPI and console activity. This new file implements a switch and keeps track of which peripheral owns the pins. It also flips over the controlling GPIO as needed Since we are adding a second file to board/nvidia/common, we create a proper Makefile there and remove the direct board.o include from board/nvidia/seaboard/Makefile Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>

2011-12-24tegra2: Tidy UART selectionSimon Glass
UART selection is done with a lot of #ifdefs. This cleans things up a little. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>
2011-12-09tegra2: Enable instruction cacheSimon Glass
Since low-level init is skipped, the instruction cache is never enabled on Tegra2. This explicitly calls this initialization as soon as the A9 is initialized. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>
2011-12-09tegra2: Add arch_cpu_init() to fire up Cortex-A9Simon Glass
We want to move away from a special Tegra2 start-up, and just use arch_cpu_init() instead. However, if we run board_init_f() from boot we need to build it for ARMv4T, since the Tegra's AVP start-up CPU does not support ARMv7. The effect of this is to do the AVP init earlier, and in arch_cpu_init(), rather that board_early_init_f().

2011-12-09tegra2: Modify MMC driver to handle power and cd GPIOsStephen Warren
Pass the GPIO numbers for power and card detect to tegra2_mmc_init(), and modify that function to perform all required GPIO initialization. This removes the need for board files to perform these operations. Move board_mmc_getcd() into tegra2_mmc.c now that the driver knows which GPIOs to use. Update affected call-sites in seaboard.c and harmony.c. Note that this change should make all SD ports work on Harmony, since the required GPIO setup is now being performed. v4: Fix prototype of tegra2_mmc_init() in board.h to match driver change.

2011-12-09tegra2: Move board_mmc_init into board filesStephen Warren
For Seaboard, this is mostly a cut/paste of board_mmc_init() and pin_mux_mmc() into seaboard.c; pin_mux_mmc() was modified to add some missing pinmux_tristate_disable calls for the GPIOs. For Harmony, those functions were modified to configure SDMMC2 (index 2) instead of SDMMC3 (index 1), since that's what is present on the board. However, harmony.c is still missing the required GPIO setup, so neither port is likely to function correctly yet. This will be fixed in the next change. v4: Include board.h to prototype tegra2_mmc_init().

2011-11-03tegra2: Move MMC clock initialization into MMC driverStephen Warren
This centralizes knowledge of MMC clocking into the MMC driver. This also removes clock setup from the board files, which will simplify later changes that modify the Harmony board to support the correct set of MMC controllers.

2011-10-27tegra2: Add more pinmux functionsSimon Glass
This adds support for changing pinmux functions of pin groups. This is done by defining a PMUX_FUNC_... enum which can be used to select the function for each group using pinmux_set_func(). It is also possible to enable pullup/pulldown, and the existing tristate functionality is retained. Also provided is a means of configuring a list of pingroups by providing a configuration table to pinmux_config_table().

2011-10-27tegra2: Rename PIN_ to PINGRP_Simon Glass
The pin groupings are better named PINGRP, since on Tegra2 they refer to multiple pins. Sorry about this, but better to get it right now when there is only a small amount of code affected. Signed-off-by: Simon Glass <sjg@chromium.org> Tested-by: Tom Warren <twarren@nvidia.com>
2011-10-27tegra2: Add more clock functionsSimon Glass

2011-10-27tegra2: Clean up board code a littleSimon Glass
This removes clock_init() and pinmux_init() which are names better suited to those respective modules. By moving board_init_f() to the bottom of the file we can remove the need for so many functions in the board.h header file. The only clock/pinmux/gpio init we need to do prior to relocation is for the UART. Signed-off-by: Simon Glass <sjg@chromium.org> Tested-by: Tom Warren <twarren@nvidia.com>
2011-10-27tegra2: Rename CLOCK_PLL_ID to CLOCK_IDSimon Glass
Rename CLOCK_PLL_ID to CLOCK_ID which takes account of the fact that the code now deals with both PLL clocks and source clocks. This also tidied up the assert() to match the one sent upstream, and fixes an error in the PWM id. Signed-off-by: Simon Glass <sjg@chromium.org> Tested-by: Tom Warren <twarren@nvidia.com>
