ARM: tegra: collect SoC sources into mach-tegra

ARM: tegra: Provide PCIEXCLK reset ID

2014-12-18T20:19:20Z

This reset is required for PCIe and the corresponding ID therefore needs to be defined. The enumeration value for this was properly defined on some SoCs but not on others. Similarly, some contained it in the mapping of peripheral IDs to clock IDs, other didn't. This patch defines it consistently for all supported SoC generations.

ARM: tegra: Implement tegra_plle_enable()

2014-12-18T20:19:20Z

This function is required by PCIe and SATA. This patch implements it on Tegra20, Tegra30 and Tegra124. It isn't implemented for Tegra114 because it doesn't support PCIe or SATA. Acked-by: Stephen Warren Signed-off-by: Thierry Reding Signed-off-by: Simon Glass Signed-off-by: Tom Warren

ARM: tegra: use MASK_BITS_* macros everywhere

2014-02-03T16:46:45Z

Not all code that set or interpreted "mux_bits" was using the named macros, but rather some was simply using hard-coded integer constants. This makes it hard to determine which pieces of code are affected by changes to those constants. Replace the integer constants with the equivalent macro definitions so that everything is nicely tied together. Note that I'm not convinced all the code was using the correct integer constants, and hence I'm not convinced that all the code is now using the desired macros. However, this change is a purely mechanical replacement and should have no functional change. Fixing any bugs will come later, separately.

Tegra114: Initialize System Counter (TSC) with osc frequency

2013-04-15T18:01:38Z

T114 needs the SYSCTR0 counter initialized so the TSC can be read by the kernel. Do it in the bootloader since it's a write-once deal (secure/non-secure mode dependent). Signed-off-by: Tom Warren Reviewed-by: Stephen Warren

Tegra: Move common clock code to arch/arm/cpu/tegra-common/clock.c

2013-02-11T17:35:24Z

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

tegra20: add clock_set_pllout function

2012-10-15T18:54:07Z

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 Signed-off-by: Tom Warren

tegra20: complete periph_id enum

2012-10-15T18:54:06Z

Most Tegra boards output the ULPI reference clock on pad DEV2. Complete the periph_id enum so that we are able to enable this clock output circuit. Signed-off-by: Lucas Stach Acked-by: Stephen Warren Acked-by: Simon Glass Signed-off-by: Tom Warren

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

2012-10-15T18:54:06Z

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. Signed-off-by: Tom Warren
