Merge tag 'omap-for-v5.2/fixes-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes

Fixes for omap variants for dra7 mmc voltage and boot issues

This series contains dra7 mmc voltage fixes, and fixes to the recent
changes to probe devices with device tree data insteas of legacy
platform data:

- Two fixes for dra7 mmc that needs 1.8V mode disabled as in case of a
  reset, the bootrom will try to access the mmc card at 3.3V potentially
  damaging the card

- Two regression fixes for am335x d_can. We must allow devices with no
  control registers for ti-sysc interconnect target module driver for
  at least d_can, and we remove the incorrect control registers for
  d_can. And we must configure the osc clock for d_can as otherwise
  register access may fail depending on the bootloader version

- Four regression fixes for dra7 variant dts files to tag rtc and usb4
  as disabled for dra71x and dra76x. These SoC variants do not have
  these devices, and got accidentally enabled when the L4 interconnect
  got defined in the dra7-l4.dtsi for the dra7 SoC family
