Merge tag 'omap-for-v4.11/soc-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/soc

SoC changes for omaps for v4.11 merge window. This adds support
for keeping the interconnect target module active for uart if
earlycon is specified. And we're adding Aaro Koskinen as a
co-maintainer for omap1 to make sure things stay working for
omap1. The other changes are mostly clean-up of old legacy code:

- Remove unused omap_display_init()
- Make omapdss_find_dss_of_node() function static
- Add support for earlycon
- Tidy up omap1 usb logging output with pr_cont
- Make omap_otg_init() static
- Delete redundant CPU class checks for omap1
- Remove unused mpurate cmdline option that has not done
  anything for past 1.5 years at least

* tag 'omap-for-v4.11/soc-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
  ARM: OMAP: clock: Remove unused mpurate cmdline option
  ARM: OMAP2+: omap_hwmod: Add support for earlycon
  MAINTAINERS: Add Aaro Koskinen as TI omap1 SoC co-maintainer
  ARM: OMAP1: USB: delete redundant CPU class checks
  ARM: OMAP1: USB: make omap_otg_init() static
  ARM: OMAP1: USB: tidy up logging output
  ARM: OMAP2+: Make the omapdss_find_dss_of_node() function static
  ARM: OMAP2+: Remove unused omap_display_init() function
