Merge tag 'omap-for-v6.5/fixes-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into arm/fixes
Fixes for omaps
A fix external abort on non-linefetch for am335x that is fixed with a flush
of posted write. And two networking fixes for beaglebone mostly for revision
c3 to do phy reset with a gpio and to fix a boot time warning.
* tag 'omap-for-v6.5/fixes-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
ARM: dts: am335x-bone-common: Add vcc-supply for on-board eeprom
ARM: dts: am335x-bone-common: Add GPIO PHY reset on revision C3 board
bus: ti-sysc: Flush posted write on enable before reset
