Merge tag 'omap-for-v4.6/soc-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/soc

Merge "omap soc changes for v4.6 merge window" from Tony Lindgren:

SoC related changes for omaps for v4.6 merge window:

- Enable runtime revision detection for dra7 to avoid multiple dts
  files for various variants

- Add dma_slave_map for omap1/2/3 legacy mode booting

- Add RTC interconnect target data for ti81xx and am43x

- Add custom reset handler for PCIeSS

- Add eDMA interconnect target data for dra7
