ARM: tegra: Remove redundant ARM_L1_CACHE_SHIFT_6 select

2016-04-12T15:09:28+00:00

These two are both ARMv7 SoCs. They need not explicitly select ARM_L1_CACHE_SHIFT_6 because it is enabled along with CPU_V7. Refer to commit a092f2b15399 ("ARM: 7291/1: cache: assume 64-byte L1 cachelines for ARMv7 CPUs"). Signed-off-by: Masahiro Yamada Signed-off-by: Thierry Reding

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. Signed-off-by: Arnd Bergmann Signed-off-by: Thierry Reding

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. Signed-off-by: Thierry Reding

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. Signed-off-by: Thierry Reding
