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
