dt-bindings: bus: Add documentation for Tegra210 ACONNECT

2016-07-01T14:35:43Z

Add binding documentation for the Tegra ACONNECT bus that is part of the Audio Processing Engine (APE) on Tegra210. The ACONNECT bus is used to access devices within the APE subsystem. The APE is located in a separate power domain and so accesses made to the ACONNECT require the power domain to be enabled as well as some platform specific clocks.

memory: omap-gpmc: Move device tree binding to correct location

2016-04-15T08:54:03Z

omap-gpmc.c is a memory controller so move the binding to the right place. Signed-off-by: Roger Quadros Acked-by: Rob Herring Acked-by: Tony Lindgren

memory: omap-gpmc: Implement IRQ domain for NAND IRQs

2016-04-15T08:52:28Z

GPMC provides 2 interrupts for NAND use. i.e. fifoevent and termcount. Use IRQ domain for this. NAND device tree node can then get the necessary interrupts by using gpmc as the interrupt parent. Legacy boot uses gpmc_get_client_irq to get the NAND interrupts from the GPMC IRQ domain. Get rid of custom bitmasks and use IRQ domain for that as well.

bus: uniphier-system-bus: add UniPhier System Bus driver

2015-12-22T19:22:39Z

The UniPhier System Bus is an external bus that connects on-board devices to the UniPhier SoC. Each bank (chip select) is dynamically mapped to the CPU-viewed address base via the bus controller. The bus controller must be configured before any access to the bus. This driver parses the "ranges" property of the System Bus node and initialized the bus controller. After the bus becomes ready, devices below it are populated. Note: Each bank can be mapped anywhere in the supported address space; there is nothing preventing us from assigning bank 0 on 0x42000000, 0x43000000, or anywhere as long as such region is not used by others. So, the "ranges" is just one possible software configuration, which does not seem to fit in device tree because device tree is a hardware description language. However, of_translate_address() requires "ranges" in every bus node between CPUs and device mapped on the CPU address space. In other words, "ranges" properties must be statically defined in device tree. After some discussion, I decided the dynamic address reassignment by the driver is too bothersome. Instead, the device tree should provide a reasonable translation setup that the OS can rely on.

bus: sunxi-rsb: Add Allwinner Reduced Serial Bus (RSB) controller bindings

2015-10-26T01:11:55Z

Reduced Serial Bus is a proprietary 2-line push-pull serial bus supporting multiple slave devices. It was developed by Allwinner, Inc. and used by Allwinner and X-Powers, Inc. for their line of PMICs and other peripheral ICs. Recent Allwinner SoCs, starting with the A23, have an RSB controller. This is used to talk to the PMIC, and later with the A80 and A83 platform, the audio codec IC.

Pull ARM SoC driver updates from Olof Johansson: "Driver updates for v4.1. Some of these are for drivers/soc, where we find more and more SoC-specific drivers these days. Some are for other driver subsystems where we have received acks from the appropriate maintainers. The larger parts of this branch are: - MediaTek support for their PMIC wrapper interface, a high-level interface for talking to the system PMIC over a dedicated I2C interface. - Qualcomm SCM driver has been moved to drivers/firmware. It's used for CPU up/down and needs to be in a shared location for arm/arm64 common code. - cleanup of ARM-CCI PMU code. - another set of cleanusp to the OMAP GPMC code" * tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (43 commits) soc/mediatek: Remove unused variables clocksource: atmel-st: select MFD_SYSCON soc: mediatek: Add PMIC wrapper for MT8135 and MT8173 SoCs arm-cci: Fix CCI PMU event validation arm-cci: Split the code for PMU vs driver support arm-cci: Get rid of secure transactions for PMU driver arm-cci: Abstract the CCI400 PMU specific definitions arm-cci: Rearrange code for splitting PMU vs driver code drivers: cci: reject groups spanning multiple HW PMUs ARM: at91: remove useless include clocksource: atmel-st: remove mach/hardware dependency clocksource: atmel-st: use syscon/regmap ARM: at91: time: move the system timer driver to drivers/clocksource ARM: at91: properly initialize timer ARM: at91: at91rm9200: remove deprecated arm_pm_restart watchdog: at91rm9200: implement restart handler watchdog: at91rm9200: use the system timer syscon mfd: syscon: Add atmel system timer registers definition ARM: at91/dt: declare atmel,at91rm9200-st as a syscon soc: qcom: gsbi: Add support for ADM CRCI muxing ...

ARM: dts: am4372: Add "ti,am437x-ocp2scp" as compatible string for OCP2SCP

2015-03-26T17:47:48Z

Added a new compatible string "ti,am437x-ocp2scp" for OCP2SCP module. This is needed since except for the OCP2SCP used in AM437x, SYNC2 value in OCP2SCP TIMING should be changed whereas the default value is sufficient in AM437x.
