2015-07-23Merge branch 'dm814x-soc' into omap-for-v4.3/socTony Lindgren
Update dm814x changes for sparse fixes to make data structures static. Conflicts: arch/arm/mach-omap2/omap_hwmod_81xx_data.c
2015-07-23ARM: OMAP4: PRM: Remove hardcoding of PRM_IO_PMCTRL_OFFSET registerKeerthy
PRM_IO_PMCTRL_OFFSET need not be same for all SOCs hence remove hardcoding and use the value provided by the omap_prcm_irq_setup structure. This is done to support IO wakeup on am437x series.

2015-07-16ARM: OMAP2+: Add custom prwdm_operations for 81xx to support dm814xTony Lindgren
Looking at the TI kernel tree I noticed that dm81xx need custom ti81xx_pwrdm_operations. Let's also change dm816x over to use them as the registers are different for dm81xx compared to others.

2015-03-31ARM: OMAP4+: PRM: determine prm_device_inst based on DT compatibilityTero Kristo
PRM device instance offset is now provided through the prm_init_data. This gets rid of some cpu_is_X / soc_is_X calls from PRM core code, preparing for PRM to be its own separate driver. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2015-03-31ARM: OMAP2+: PRM: move SoC specific init calls within a generic APITero Kristo
This gets rid of need for some exported driver APIs, and simplifies the initialization of the PRM driver. Done in preparation to make PRM a separate driver. The init data is now also passed to the SoC specific implementations, allowing future expansion to add feature flags etc. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2015-03-27ARM: OMAP2+: CM: determine CM base address from device treeTero Kristo
There is no need to provide the CM base address through a low-level API from the low-level IO init, as this information is available through DT. Re-routed the parsing function to be called from the CM drivers also to simplify the implementation under io.c. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2015-03-25ARM: OMAP2+: PRCM: add support for static clock memmap indicesTero Kristo
All clock provider related drivers will now register their iomaps with a static index. This makes it easier to split up the individual drivers to their own files in subsequent patches. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2015-01-17ARM: OMAP: Work around hardcoded interruptsMarc Zyngier
Commit 9a1091ef0017 ("irqchip: gic: Support hierarchy irq domain") changed the GIC driver to use a non-legacy IRQ domain on DT platforms. This patch assumes that DT-driven systems are getting all of their interrupts from device tree. Turns out that OMAP has quite a few hidden gems, and still uses hardcoded interrupts despite having fairly complete DTs. This patch attempts to work around these by offering a translation method that can be called directly from the hwmod code, if present. The same hack is sprinkled over PRCM and TWL. It isn't pretty, but it seems to do the job without having to add more hacks to the interrupt controller code. Tested on OMAP4 (Panda-ES) and OMAP5 (UEVM5432).

Pull support for three new arm SoC types from Arnd Bergmann: - The mvebu platform includes Marvell's Armada XP and Armada 370 chips, made by the mvebu business unit inside of Marvell. 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() ...

2011-12-16ARM: OMAP: PRCM: add suspend prepare / finish supportTero Kristo
PRCM chain handler needs to disable forwarding of interrupts during suspend, because runtime PM is disabled and most of the drivers are potentially not able to handle interrupts coming at this time. This patch masks all the PRCM interrupt events if a PRCM interrupt occurs during suspend, but does not ack them. Once suspend finish is called, all the masked events will be re-enabled, which causes immediate PRCM interrupt and handles the postponed event. The suspend prepare and complete callbacks will be called from pm34xx.c / pm44xx.c files in the following patches. The functions defined in this patch should eventually be moved to suspend->prepare and suspend->finish driver hooks, once the PRCM chain handler will be made as its own driver.

2011-12-16ARM: OMAP: PRCM: add support for chain interrupt handlerTero Kristo
Introduce a chained interrupt handler mechanism for the PRCM interrupt, so that individual PRCM event can cleanly be handled by handlers in separate drivers. We do this by introducing PRCM event names, which are then matched to the particular PRCM interrupt bit depending on the specific OMAP SoC being used. PRCM interrupts have two priority levels, high or normal. High priority is needed for IO event handling, so that we can be sure that IO events are processed before other events. This reduces latency for IO event customers and also prevents incorrect ack sequence on OMAP3.

In preparation for adding OMAP4-specific PRCM accessor/mutator functions, split the existing OMAP2/3 PRCM code into OMAP2/3-specific files. Most of what was in mach-omap2/{cm,prm}.{c,h} has now been moved into mach-omap2/{cm,prm}2xxx_3xxx.{c,h}, since it was OMAP2xxx/3xxx-specific. This process also requires the #includes in each of these files to be changed to reference the new file name. As part of doing so, add some comments into plat-omap/sram.c and plat-omap/mcbsp.c, which use "sideways includes", to indicate that these users of the PRM/CM includes should not be doing so.

For example, OMAP4430_PRM_*_MOD macros have been moved into the prm44xx.h header. Adjust #includes of all files that used the old PRCM header file names to point to the new filenames.

2009-05-28OMAP2/3: PM: push core PM code from linux-omapKevin Hilman
This patch is to sync the core linux-omap PM code with mainline. This code has evolved and been used for a while the linux-omap tree, but the attempt here is to finally get this into mainline. Following this will be a series of patches from the 'PM branch' of the linux-omap tree to add full PM hardware support from the linux-omap tree. Much of this PM core code was written by Jouni Hogander with significant contributions from Paul Walmsley as well as many others from Nokia, Texas Instruments and linux-omap community.

2009-02-08[ARM] OMAP2 PRCM: clean up CM_IDLEST bitsPaul Walmsley
This patch fixes a few OMAP2xxx CM_IDLEST bits that were incorrectly marked as being OMAP2xxx-wide, when they were actually 2420-specific. Also, originally when the PRCM register macros were defined, bit shift macros used a "_SHIFT" suffix, and mask macros used none. This became a source of bugs and confusion, as the mask macros were mistakenly used for shift values. Gradually, the mask macros have been updated, piece by piece, to add a "_MASK" suffix on the end to clarify. This patch applies this change to the CM_IDLEST_* register bits. The patch also adds a few bits that were missing, mostly from the 3430ES1 to ES2 revisions. linux-omap source commits are d18eff5b5fa15e170794397a6a94486d1f774f77, e1f1a5cc24615fb790cc763c96d1c5cfe6296f5b, and part of 9fe6b6cf8d9e0cbb429fd64553a4b3160a9e99e1 Signed-off-by: Paul Walmsley <paul@pwsan.com> Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
