Merge tag 'omap-for-v4.19/fixes-v2-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes

Fixes for omap variants against v4.19-rc1

These are mostly fixes related to using ti-sysc interconnect target module
driver for accessing right register offsets for sgx and cpsw and for
no_console_suspend regression.

There is also a droid4 emmc fix where emmc may not get detected for some
models, and vibrator dts mismerge fix.

And we have a file permission fix for am335x-osd3358-sm-red.dts that
just got added. And we must tag RTC as system-power-controller for
am437x for PMIC to shut down during poweroff.
