…inux/kernel/git/tmlind/linux-omap into next/pm

From Tony Lindgren <tony@atomide.com>:

PM updates for omaps via Kevin Hilman <khilman@deeprootsystems.com>:

- Minor pr_warn() cleanup for OMAP2+ Voltage Processor (VP)

- OMAP: SmartReflex: pass device-independent data via platform_data

- OMAP voltage layer updates towards supporting auto-retention/auto-off

* tag 'omap-for-v3.8/pm-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
  ARM: OMAP4: OPP: add OMAP4460 definitions
  ARM: OMAP4: TWL: enable high speed mode for PMIC communication
  ARM: OMAP4: VC: setup I2C parameters based on board data
  ARM: OMAP4: vc: fix channel configuration
  ARM: OMAP3+: voltage: remove unused volt_setup_time parameter
  ARM: OMAP: TWL: change the vddmin / vddmax voltages to spec
  ARM: OMAP3+: voltage: use oscillator data to calculate setup times
  ARM: OMAP3+: vp: use new vp_params for calculating vddmin and vddmax
  ARM: OMAP: add support for oscillator setup
  ARM: OMAP4: VC: calculate ramp times
  ARM: OMAP4: voltage: add support for VOLTSETUP_x_OFF register
  ARM: OMAP3: VC: calculate ramp times
  ARM: OMAP3+: voltage: introduce omap vc / vp params for voltagedomains
  ARM: OMAP: voltage: renamed vp_vddmin and vp_vddmax fields
  ARM: OMAP3+: PM: VP: use uV for max and min voltage limits
  ARM: OMAP2+: PM: VP: minor pr_warn updates
  ARM: OMAP: SmartReflex: pass device dependent data via platform data
  ARM: OMAP: hwmod: align the SmartReflex fck names
