tegra20: rework UART GPIO handling

2012-10-15T18:54:07+00:00

Rename board provided gpio_config_uart() to
gpio_early_init_uart() as it does the same thing as the equally
called function provided by the uart-switch code. This allows
to simply call this function in early board init whether or not
we are building with CONFIG_UART_SWITCH defined.

Also provide a weak symbol for this function, to avoid the
need to provide this function for boards that don't need any
fixup.

This patch supersedes the earlier posted
"tegra: convert gpio_config_uart to weak symbol".
Build tested with MAKEALL -s tegra20

Tegra20: Move some include files to arch-tegra for sharing with Tegra30

2012-10-15T18:54:06+00:00

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.

Tegra: Change Tegra20 to Tegra in common code, prep for T30

2012-09-10T20:01:24+00:00

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.

tegra20: rename tegra2 -> tegra20

2012-09-01T12:58:21+00:00

This is make naming consistent with the kernel and devicetree and in
preparation of pulling out the common tegra20 code.

tegra: fix leftover CONFIG_TEGRA2_MMC & _SPI build switches

2012-07-09T20:44:32+00:00

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.

tegra: Use SD write-protect GPIO on Tamonten

2012-07-09T20:44:32+00:00

GPIO PI6 can be used to obtain the write-protect status of an SD card
inserted into the SD slot.

tegra: Implement gpio_early_init() on Tamonten

2012-07-09T20:44:32+00:00

The PI4 GPIO is used on Tamonten to reset carrier board peripherals.
Power sequencing hardware on the carrier pulls the reset low before
powering up the Tegra, and the CPU is supposed to signal readiness,
and therefore bring peripherals out of reset by pulling PI4 high.

tegra: Rework Tamonten support

2012-07-09T20:44:32+00:00

This commit uses the common Tegra board implementation instead of
duplicating a lot of the code. In addition, the Plutux and Medcom
specific board files can be removed as the MMC/SD setup is common
among all Tamonten-based boards.

tegra: Use funcmux for MMC on tamonten

Use the new funcmux_select() feature to set up the MMC pin mux.

tegra: Move boards over to use arch-level board UART function

2011-12-24T09:23:32+00:00

Now that we can set up the UART in common tegra code, make the boards
use it.
