Mainly because it was hard to sort the branch contents in a way that fit our existing branches due to some refactorings.

| | * ARM: tegra: select USB_ULPI from EHCI rather than platformArnd Bergmann2015-11-241-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <treding@nvidia.com>
| | * soc/tegra: Provide per-SoC Kconfig symbolsThierry Reding2015-11-242-0/+70
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

It has been a tremendous amount of cleanup and refactoring by a huge number of people, and creation of several new (and major) subsystems to better abstract out all the platform details in an appropriate manner. The bulk of this branch is a large patchset from Arnd that brings several of the more minor and older platforms we have closer to multiplatform support. Among these are MMP, S3C64xx, Orion5x, mv78xx0 and realview Much of this is moving around header files from old mach directories, but there are also some cleanup patches of debug_ll (lowlevel debug per-platform options) and other parts. Linus Walleij also has some patchs to clean up the older ARM Realview platforms by finally introducing DT support, and Rob Herring has some for ARM Versatile which is now DT-only. Both of these platforms are now multiplatform. Finally, a couple of patches from Russell for Dove PMU, and a fix from Valentin Rothberg for Exynos ADC, which were rebased on top of the series to avoid conflicts" * tag 'armsoc-multiplatform' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (75 commits) ARM: realview: don't select SMP_ON_UP for UP builds ARM: s3c: simplify s3c_irqwake_{e,}intallow definition ARM: s3c64xx: fix pm-debug compilation iio: exynos-adc: fix irqf_oneshot.cocci warnings ARM: realview: build realview-dt SMP support only when used ARM: realview: select apropriate targets ARM: realview: clean up header files ARM: realview: make all header files local ARM: no longer make CPU targets visible separately ARM: integrator: use explicit core module options ARM: realview: enable multiplatform ARM: make default platform work for NOMMU ARM: debug-ll: move DEBUG_LL_UART_EFM32 to correct Kconfig location ARM: defconfig: use correct debug_ll settings ARM: versatile: convert to multi-platform ARM: versatile: merge mach code into a single file ARM: versatile: switch to DT only booting and remove legacy code ARM: versatile: add DT based PCI detection ARM: pxa: mark ezx structures as __maybe_unused ARM: pxa: mark raumfeld init functions as __maybe_unused ...

Currently hwqueue driver configures linking RAM(s) to be used cooperatively by the QMs (shared mode). Therefore if both queue managers are used then both must be configured with exactly the same linking RAM info (base address and size) independent of the number of linking RAM(s) specified in the device tree. For proper operation only one linking RAM is required and in most cases this can be internal one as long as it is able to handle the number of descriptors used in the system. Current driver code however skips configuration of second queue manager if second linking RAM is not specified. If the configuration for the QM2 is missing there will be a crash when it tries to push/pop descriptors from its queues.

Having the RPM message ram in the smem DT node's reg property leads to the smem node being located in different places depending on if the message ram is being used or not. Let's add a qcom specific property, qcom,rpm-msg-ram, and point to the device memory from the SMEM node via a phandle. As SMEM is a software construct, it really needs to reside at the root of the DT regardless of whether it's using the message ram or not.
