Merge tag 'omap-for-v3.20/cleanup-pt1' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/cleanup

Merge "omap clean-up for v3.20" from Tony Lindgren:

Clean-up for omaps to remove dead code found with cppcheck after
we've made several SoCs to boot in device tree only mode.

* tag 'omap-for-v3.20/cleanup-pt1' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
  ARM: OMAP2+: Remove unused ti81xx platform init code
  ARM: OMAP3+: PRM: remove prm_get_reset_sources declaration from headers
  ARM: OMAP2: CM: remove unused PLL functions
  ARM: OMAP2: clock: remove unused apll code
  ARM: OMAP: dma.c: Remove unused function
  ARM: OMAP1: timer32k.c: Remove unused function
  ARM: OMAP1: irq.c: Remove unused function
  ARM: OMAP2+: omap-pm-noop.c: Remove some unused functions
  ARM: OMAP2+: voltage: Remove some unused functions
  ARM: OMAP2+: powerdomain.c: Remove some unused functions
  ARM: OMAP2+: omap_hwmod.c: Remove some unused functions
  ARM: OMAP2+: dpll44xx.c: Remove unused function
  ARM: OMAP2+: cm33xx.c: Remove some unused functions

- * @r: minimum rate in Hz
- *
- * Request that the minimum clock rate on the device @dev's clk @clk
- * be no less than @r Hz.
- *
- * It is expected that the OMAP PM code will use this information to
- * find an OPP or clock setting that will satisfy this clock rate
- * constraint, along with any other applicable system constraints on
- * the clock rate or corresponding voltage, etc.
- *
- * omap_pm_set_min_clk_rate() differs from the clock code's
- * clk_set_rate() in that it considers other constraints before taking
- * any hardware action, and may change a system OPP rather than just a
- * clock rate.  clk_set_rate() is intended to be a low-level
- * 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
- * device subsystem) has both the subsystem-specific knowledge, and
- * 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
- * previous rate value for the device @dev.  To remove the minimum clock
- * rate constraint for the device, call with r = 0.
