Merge tag 'omap-for-v4.21/driver-part2-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/drivers
Few more omap driver fixes and improvments for v4.21 merge window
This series of changes improves the TI module flag handling to allow
booting with older dts files until the module flags have been moved
to the interconnect target module level. And there's a of_node_name_eq()
clean-up patch from Rob Herring for the GPMC driver.
* tag 'omap-for-v4.21/driver-part2-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
memory: omap-gpmc: Use of_node_name_eq for node name comparisons
bus: ti-sysc: Check for no-reset and no-idle flags at the child level
ARM: OMAP2+: Check also the first dts child for hwmod flags
