Since the same group also made the older but similar platforms we call "orion5x", "kirkwood", "mv78xx0" and "dove", we plan to move all of them into the mach-mvebu directory in the future. - socfpga is Altera's platform based on Cortex-A9 cores and a lot of FPGA space. This is similar to the Xilinx zynq platform we already support. The code is particularly clean, which is helped by the fact that the hardware doesn't do much besides the parts that are expected to get added in the FPGA. - The OMAP subarchitecture gains support for the latest generation, the OMAP5 based on the new Cortex-A15 core. Support is rather rudimentary for now, but will be extended in the future. * tag 'newsoc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (25 commits) ARM: socfpga: initial support for Altera's SOCFPGA platform arm: mvebu: generate DTBs for supported SoCs ARM: mvebu: MPIC: read number of interrupts from control register arm: mach-mvebu: add entry to MAINTAINERS arm: mach-mvebu: add compilation/configuration change arm: mach-mvebu: add defconfig arm: mach-mvebu: add documentation for new device tree bindings arm: mach-mvebu: add support for Armada 370 and Armada XP with DT arm: mach-mvebu: add source files arm: mach-mvebu: add header clocksource: time-armada-370-xp: Marvell Armada 370/XP SoC timer driver ARM: Kconfig update to support additional GPIOs in OMAP5 ARM: OMAP5: Add the build support arm/dts: OMAP5: Add omap5 dts files ARM: OMAP5: board-generic: Add device tree support ARM: omap2+: board-generic: clean up the irq data from board file ARM: OMAP5: Add SMP support ARM: OMAP5: Add the WakeupGen IP updates ARM: OMAP5: l3: Add l3 error handler support for omap5 ARM: OMAP5: gpmc: Update gpmc_init() ...

As for the previous releases, both the Armada 370 and the Armada XP SoCs are supported in this directory, and we are able to build a single kernel image that boots on both SoCs. Both SoCs use the PJ4B processor, a Marvell-developed ARM core that implements the ARMv7 instruction set. We are currently using Marvell evaluation boards for both of those SoCs, and the support for those boards is added in this patch set. This patch set, and the support for those SoCs, started as a collaborative effort from Marvell engineers (who have done the initial development work) and Free Electrons engineers (who are reshaping the code for mainline submission, adding device tree support, etc.). This effort has also received contributions from Ben Dooks from Codethink. * mvebu/newsoc: ARM: mvebu: MPIC: read number of interrupts from control register arm: mach-mvebu: add entry to MAINTAINERS arm: mach-mvebu: add compilation/configuration change arm: mach-mvebu: add defconfig arm: mach-mvebu: add documentation for new device tree bindings arm: mach-mvebu: add support for Armada 370 and Armada XP with DT arm: mach-mvebu: add source files arm: mach-mvebu: add header clocksource: time-armada-370-xp: Marvell Armada 370/XP SoC timer driver Changes from Arnd * Pulled from git://github.com/Marvell-Semi/EBU_mainline_public.git mvebu_for-next-V9 * rebased onto v3.5-rc5 because it was originally based on an old arm-soc/for-next branch Signed-off-by: Arnd Bergmann <arnd@arndb.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As per recent discussion on the linux-omap list, we are moving in the direction where, we will have only architecture, ARCH_OMAP2PLUS and all devices/platforms will be treated as a SoC underneath. So the first step in this direction is to adopt this change for all new devices getting in, converting cpu_is_am33xx/335x() ==> soc_is_am33xx/335x() Signed-off-by: Vaibhav Hiremath <hvaibhav@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

But while adding complete baseport support (like, clock, power and hwmod) support, it is observed that, we are creating more and more problems by treating am33xx device as omap3 family, as nothing matches between them (except cortex-A8 mpu). So, after long discussion we have came to the conclusion that, we should not consider am33xx device as omap3 family, instead create separate class (SOC_AM33XX) under OMAP2PLUS. This means, for am33xx device, cpu_is_omap34xx() will return false, and only cpu_is_am33xx() will be true.

When the DMA must perform read/write accesses, the DMADISABLE bit is cleared by the hardware. But when the DMA must stop for power management, software must set the DMADISABLE bit back to 1. In cases where the ROMCODE/BOOTLOADER uses dma, the hardware clears the DMADISABLE bit (but the romcode/bootloader might not set it back to 1). In order for the kernel to start in a clean state, it is necessary for the kernel to set DMADISABLE bit back to 1 (irrespective of whether it's been set to 1 in romcode or bootloader). During _reset of the (hwmod)device, the DMADISABLE bit is set so that it does not prevent idling of the system. (NOTE: having DMADISABLE to 0, prevents the system to idle) DMADISABLE bit is present in usbotgss module of omap5.

However, during the registering of the wake-up power domain the state of the domain is queried by calling pwrdm_read_pwrst(). This actually tries to read a register that does not exist and returns a value of 0 that indicates that the current state is OFF. The OFF state count of the wake-up power domain is then set to 1 and the current state to OFF. Both of which are incorrect. To fix this, if a power domain only supports the ON state, do not attempt to read the power state status register and simply return ON as the current power state. This is based upon Tony's current linux-omap master branch. Testing: - Boot tested on OMAP4460 panda. - Boot tested on OMAP3430 beagle and validated CORE RET still working (using Paul's 32k timer patch [1]).

| | | * | ARM: OMAP4: clockdomain/CM code: Update supported transition modesJon Hunter2012-07-04

NO_SLEEP (0x0) - A clock domain sleep transition is never initiated, irrespective of the hardware conditions. SW_SLEEP (0x1) - A software-forced sleep transition. The transition is initiated when the associated hardware conditions are satisfied SW_WKUP (0x2) - A software-forced clock domain wake-up transition is initiated, irrespective of the hardware conditions. HW_AUTO (0x3) - Hardware-controlled automatic sleep and wake-up transition is initiated by the PRCM module when the associated hardware conditions are satisfied. For OMAP4 devices, SW_SLEEP is equivalent to HW_AUTO and NO_SLEEP is equivalent to SW_WKUP. The only difference between HW_AUTO and SW_SLEEP for OMAP4 devices is that the PRM_IRQSTATUS_MPU.TRANSITION_ST interrupt status is set in case of SW_SLEEP transition, and not set in case of HW_AUTO transition. For OMAP4 devices, all CLKDMs support HW_AUTO and therefore we can place the CLKDMs in the HW_AUTO state instead of the SW_SLEEP mode. Hence, we do not need to use the SW_SLEEP mode. With regard to NO_SLEEP and SW_WKUP it is preferred to use SW_WKUP mode if the CLKDM supports it and so use this mode instead of NO_SLEEP where possible. For a software perspective the above 4 modes are represented by the following flags to indicate what modes are supported by each of the CLKDMs. CLKDM_CAN_DISABLE_AUTO --> NO_SLEEP CLKDM_CAN_ENABLE_AUTO --> HW_AUTO CLKDM_CAN_FORCE_SLEEP --> SW_SLEEP CLKDM_CAN_FORCE_WAKEUP --> SW_WKUP By eliminating the SW_SLEEP mode the the mapping of the flags for OMAP4 devices can becomes ... CLKDM_CAN_DISABLE_AUTO --> NO_SLEEP CLKDM_CAN_ENABLE_AUTO --> HW_AUTO CLKDM_CAN_FORCE_SLEEP --> HW_AUTO CLKDM_CAN_FORCE_WAKEUP --> SW_WKUP Cc: Ming Lei <ming.lei@canonical.com> Cc: Will Deacon <will.deacon@arm.com> Cc: Benoit Cousson <b-cousson@ti.com> Cc: Paul Walmsley <paul@pwsan.com> Cc: Kevin Hilman <khilman@ti.com> Reviewed-by: Benoit Cousson <b-cousson@ti.com> Reviewed-by: Santosh Shilimkar <santosh.shilimkar@ti.com> Signed-off-by: Jon Hunter <jon-hunter@ti.com> Signed-off-by: Paul Walmsley <paul@pwsan.com>
