Merge tag 'mips_5.2_2' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux
Pull a few more MIPS updates from Paul Burton: "Some SGI IP27 specific PCI rework and a batch of fixes: - A build fix for BMIPS5000 configurations with CONFIG_HW_PERF_EVENTS=y, which also neatly removes some #ifdefery. - A fix to report supported ISAs correctly on older Ingenic SoCs which incorrectly indicate MIPSr2 support in their cop0 Config register. - Some PCI modernization for SGI IP27 systems as part of ongoing work to support some other SGI systems. - A fix allowing use of appended DTB files with generic kernels. - DMA mask fixes for SGI IP22 & Alchemy systems" * tag 'mips_5.2_2' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux: MIPS: Alchemy: add DMA masks for on-chip ethernet MIPS: SGI-IP22: provide missing dma_mask/coherent_dma_mask generic: fix appended dtb support MIPS: SGI-IP27: abstract chipset irq from bridge MIPS: SGI-IP27: use generic PCI driver MIPS: Fix Ingenic SoCs sometimes reporting wrong ISA MIPS: perf: Fix build with CONFIG_CPU_BMIPS5000 enabled
