Merge tag 'for-linus' of git://github.com/openrisc/linux
Pull OpenRISC updates from Stafford Horne:
"Few small things for 5.4:
- Fixup ethoc ethernet device tree descriptors which were previously
broken, now ethernet works on FPGAs running OpenRISC!
- Switch ioremap to use uncached semantics - from Christoph Hellwig"
* tag 'for-linus' of git://github.com/openrisc/linux:
openrisc: map as uncached in ioremap
or1k: dts: Add ethoc device to SMP devicetree
or1k: dts: Fix ethoc network configuration in or1ksim devicetree
