ARM: tegra: select USB_ULPI from EHCI rather than platform

2015-11-24T15:47:26+00:00

For historic reasons, the tegra platform selects USB_ULPI from architecture
code, but that hasn't really made sense for a long time, as the only
user of that code is the Tegra EHCI driver that has its own Kconfig
symbol.

This removes the 'select' statements from mach-tegra and drivers/soc/tegra
and adds them with the device driver that actually needs them.

soc/tegra: Add Tegra210 support

2015-11-24T15:47:24+00:00

Also known as Tegra X1, the Tegra210 has four Cortex-A57 cores paired
with four Cortex-A53 cores in a switched configuration. It features a
GPU using the Maxwell architecture with support for DX11, SM4, OpenGL
4.5, OpenGL ES 3.1 and providing 256 CUDA cores. It supports hardware
accelerated en- and decoding of various video standards including
H.265, H.264 and VP8 at 4K resolutions and up to 60 fps.

Besides the multimedia features it also comes with a variety of I/O
controllers such as GPIO, I2C, SPI, SDHCI, PCIe, SATA and XHCI, to
name only a few.

Add a Kconfig option for Tegra210 to allow SoC-specific support to be
enabled for this new generation.

soc/tegra: Provide per-SoC Kconfig symbols

2015-11-24T15:47:24+00:00

Move per-SoC generation Kconfig symbols to drivers/soc/tegra/Kconfig to
gather them all in a single place. This directory is a natural location
for these options since it already contains the drivers that are shared
across 32-bit and 64-bit ARM architectures.

soc/tegra: pmc: Use existing pclk reference

2015-08-13T14:49:58+00:00

The driver requests the pclk clock at probe time already and stores its
reference to it in struct tegra_pmc, so there is no need to look it up
everytime it is needed. Use the existing reference instead.

soc/tegra: pmc: Remove unnecessary return statement

2015-08-13T14:49:43+00:00

Functions returning no value don't need an explicit return statement.

soc: tegra: Remove redundant $(CONFIG_ARCH_TEGRA) in Makefile

2015-08-13T14:17:40+00:00

Kbuild descends into drivers/soc/tegra/ only when CONFIG_ARCH_TEGRA
is enabled. (see drivers/soc/Makefile)

$(CONFIG_ARCH_TEGRA) in drivers/soc/tegra/Makefile always evaluates
to 'y'.

soc/tegra: fuse: Add spare bit offset for Tegra210

2015-07-16T08:38:31+00:00

The offset of the first spare bit register on Tegra210 is 0x380, but
account for the fixed offset of 0x100 in the fuse accessor.

The offset of the first spare bit register on Tegra124 is 0x300, but
account for the fixed offset of 0x100 in the fuse accessor.

soc/tegra: fuse: Rename core_* to soc_*

2015-07-16T08:38:29+00:00

There's a mixture of core_* and soc_* prefixes for variables storing
information related to the VDD_CORE rail. Choose one (soc_*) and use it
more consistently.
