Merge tag 'cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC cleanups from Olof Johansson: "This is a good healthy set of various code removals. Total net delta is 8100 lines removed. Among the larger cleanups are: - Removal of old Samsung S3C DMA infrastructure by Arnd - Removal of the non-DT version of the 'lager' board by Magnus Damm - General stale code removal on OMAP and Davinci by Rickard Strandqvist - Removal of non-DT support on am3517 platforms by Tony Lindgren ... plus several other cleanups of various platforms across the board" * tag 'cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (47 commits) ARM: sirf: drop redundant function and marco declaration arm: omap: specify PMUs are for ARMv7 CPUs arm: shmobile: specify PMUs are for ARMv7 CPUs arm: iop: specify PMUs are for XScale CPUs arm: pxa: specify PMUs are for XScale CPUs arm: realview: specify PMU types ARM: SAMSUNG: remove unused DMA infrastructure ARM: OMAP3: Add back Kconfig option MACH_OMAP3517EVM for ASoC ARM: davinci: Remove CDCE949 driver ARM: at91: remove useless at91rm9200_set_type() ARM: at91: remove useless at91rm9200_dt_initialize() ARM: at91: move debug-macro.S into the common space ARM: at91: remove useless at91_sysirq_mask_rtx ARM: at91: remove useless config MACH_AT91SAM9_DT ARM: at91: remove useless config MACH_AT91RM9200_DT ARM: at91: remove unused mach/memory.h ARM: at91: remove useless header file includes ARM: at91: remove unneeded header file rtc: at91/Kconfig: remove useless options ARM: at91/Documentation: add a README for Atmel SoCs ...

- * interface.
- *
- * omap_pm_set_min_clk_rate() is easily open to abuse.  A better API
- * would be something like "omap_pm_set_min_dev_performance()";
- * however, there is no easily-generalizable concept of performance
- * that applies to all devices.  Only a device (and possibly the

- * the hardware IP block-specific knowledge, to translate a constraint
- * on "touchscreen sampling accuracy" or "number of pixels or polygons
- * rendered per second" to a clock rate.  This translation can be
- * dependent on the hardware IP block's revision, or firmware version,
- * and the driver is the only code on the system that has this
- * information and can know how to translate that into a clock rate.
- *
- * The intended use-case for this function is for userspace or other
- * kernel code to communicate a particular performance requirement to
- * a subsystem; then for the subsystem to communicate that requirement
- * to something that is meaningful to the device driver; then for the
- * device driver to convert that requirement to a clock rate, and to
- * then call omap_pm_set_min_clk_rate().
- *
- * Users of this function (such as device drivers) should not simply
- * call this function with some high clock rate to ensure "high
- * performance."  Rather, the device driver should take a performance
- * constraint from its subsystem, such as "render at least X polygons
- * per second," and use some formula or table to convert that into a
- * clock rate constraint given the hardware type and hardware
- * revision.  Device drivers or subsystems should not assume that they
- * know how to make a power/performance tradeoff - some device use
- * cases may tolerate a lower-fidelity device function for lower power
- * consumption; others may demand a higher-fidelity device function,
- * no matter what the power consumption.
- *
- * Multiple calls to omap_pm_set_min_clk_rate() will replace the
