Pull ARM DT updates from Olof Johansson: "As always, this tends to be one of our bigger branches. There are lots of updates this release, but not that many jumps out as something that needs more detailed coverage. Some of the highlights are: - DTs for the new Annapurna Labs Alpine platform - more graphics DT pieces falling into place on Exynos, bridges, clocks. - plenty of DT updates for Qualcomm platforms for various IP blocks - some churn on Tegra due to switch-over to tool-generated pinctrl data - misc fixes and updates for Atmel at91 platforms - various DT updates to add IP block support on Broadcom's Cygnus platforms - more updates for Renesas platforms as DT support is added for various IP blocks (IPMMU, display, audio, etc)" * tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (231 commits) ARM: dts: alpine: add internal pci Revert "ARM: dts: mt8135: Add pinctrl/GPIO/EINT node for mt8135."

ARM: 8335/1: Documentation: DT bindings: Tegra AHB: document the legacy base address

2015-04-02T09:03:56Z

Documentation: DT bindings: Tegra AHB: require the legacy base address for existing chips Per Stephen Warren, note in the Tegra AHB DT binding documentation that we specifically deprecate any attempt to use the IP block's actual hardware base address, and advocate the use of the legacy "off-by-four" address in the 'regs' property, for Tegra chips with existing upstream Linux DT files that include a Tegra AHB node. This patch updates the documentation accordingly. Changing the existing kernel DT data isn't under consideration because Linux kernel DT data policy is to preserve compatibility between newer DT data files and older kernels. However, this additional step of changing the documentation should discourage others from sending kernel patches to try to change the legacy kernel DT data. Furthermore, for out-of-tree software (such as bootloaders or other operating systems) that may rely on Linux kernel DT binding documentation as an ABI (but not the Linux kernel DT data itself), such a change may allow future convergence with the Linux kernel DT data without additional code changes.

Pull ARM SoC platform changes from Olof Johansson: "New and updated SoC support. Also included are some cleanups where the platform maintainers hadn't separated cleanups from new developent in separate branches. Some of the larger things worth pointing out: - A large set of changes from Alexandre Belloni and Nicolas Ferre preparing at91 platforms for multiplatform and cleaning up quite a bit in the process. - Removal of CSR's "Marco" SoC platform that never made it out to the market. We love seeing these since it means the vendor published support before product was out, which is exactly what we want! New platforms this release are: - Conexant Digicolor (CX92755 SoC) - Hisilicon HiP01 SoC - CSR/sirf Atlas7 SoC - ST STiH418 SoC - Common code changes for Nvidia Tegra132 (64-bit SoC) We're seeing more and more platforms having a harder time labelling changes as cleanups vs new development -- which is a good sign that we've come quite far on the cleanup effort.

Documentation: DT bindings: add more Tegra chip compatible strings

2015-02-04T02:37:31Z

Align compatible strings for several IP blocks present on Tegra chips with the latest doctrine from the DT maintainers: http://marc.info/?l=devicetree&m=142255654213019&w=2 The primary objective here is to avoid checkpatch warnings, per: http://marc.info/?l=linux-tegra&m=142201349727836&w=2 DT binding text files have been updated for the following IP blocks: - PCIe - SOR - SoC timers - AHB "gizmo" - APB_MISC - pinmux control - UART - PWM - I2C - SPI - RTC - PMC - eFuse - AHCI - HDA - XUSB_PADCTRL - SDHCI - SOC_THERM - AHUB - I2S - EHCI - USB PHY N.B. The nvidia,tegra20-timer compatible string is removed from the nvidia,tegra30-timer.txt documentation file because it's already mentioned in the nvidia,tegra20-timer.txt documentation file. This second version takes into account the following requests from Rob Herring : - Per-IP block patches have been combined into a single patch - Explicit documentation about which compatible strings are actually matched by the driver has been removed. In its place is implicit documentation that loosely follows Rob's prescribed format: "Must contain '"nvidia,-pcie", "nvidia,tegra20-pcie"' where is tegra30, tegra132, ..."

ARM: tegra: add missing clock documentation to DT bindings

2013-12-11T23:41:55Z

Many of the Tegra DT binding documents say nothing about the clocks or clock-names properties, yet those are present and required in DT files. This patch simply updates the documentation file to match the implicit definition of the binding, based on real-world DT content. All Tegra bindings that mention clocks are updated to have consistent wording and formatting of the clock-related properties. Signed-off-by: Stephen Warren Acked-By: Terje Bergstrom

ARM: dt: tegra: add bindings of power management configurations for PMC

2013-04-03T20:31:36Z

The PMC mostly controls the entry and exit of the system from different sleep modes. Different platform or system may have different configurations. The power management configurations of PMC is represented as some properties. The system needs to define the properties when the system supports deep sleep mode (i.e. suspend).
