Merge tag 'omap-for-v4.16/ti-sysc-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/drivers

TI sysc driver updates for v4.16 merge window

We now have gotten ti-sysc driver to the point where it can parse
interconnect target configuration from device tree instead of the
legacy platform data. This series updates the device tree binding
and adds parsing to the driver for quirks and capabilities.

* tag 'omap-for-v4.16/ti-sysc-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
  bus: ti-sysc: Add parsing of module capabilities
  bus: ti-sysc: Handle module quirks based dts configuration
  bus: ti-sysc: Detect i2c interconnect target module based on register layout
  bus: ti-sysc: Add register bits for interconnect target modules
  bus: ti-sysc: Make omap_hwmod_sysc_fields into sysc_regbits platform data
  ARM: OMAP2+: Move all omap_hwmod_sysc_fields to omap_hwmod_common_data.c
  ARM: dts: Add generic ti,sysc compatible in addition to the custom ones
  dt-bindings: ti-sysc: Update binding for timers and capabilities
