Pull MIPS updates from Paul Burton: "A light batch this time around but significant improvements for certain systems: - Removal of readq & writeq for MIPS32 kernels where they would simply BUG() anyway, allowing drivers or other code that #ifdefs on their presence to work properly. - Improvements for Ingenic JZ4740 systems, including support for the external memory controller & pinmuxing fixes for qi_lb60/NanoNote systems. - Improvements for Lantiq systems, in particular around SMP & IPIs. - DT updates for ralink/MediaTek MT7628a systems to probe & configure a bunch more devices. - Miscellaneous cleanups & build fixes" * tag 'mips_5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux: (30 commits) MIPS: fix some more fall through errors in arch/mips MIPS: perf events: handle switch statement falling through warnings mips/kprobes: Export kprobe_fault_handler() MAINTAINERS: Add myself as Ingenic SoCs maintainer MIPS: ralink: mt7628a.dtsi: Add watchdog controller DT node MIPS: ralink: mt7628a.dtsi: Add SPI controller DT node MIPS: ralink: mt7628a.dtsi: Add GPIO controller DT node MIPS: ralink: mt7628a.dtsi: Add pinctrl DT properties to the UART nodes MIPS: ralink: mt7628a.dtsi: Add pinmux DT node MIPS: ralink: mt7628a.dtsi: Add SPDX GPL-2.0 license identifier MIPS: lantiq: Add SMP support for lantiq interrupt controller MIPS: lantiq: Shorten register names, remove unused macros MIPS: lantiq: Fix bitfield masking MIPS: lantiq: Remove unused macros MIPS: lantiq: Fix attributes of of_device_id structure MIPS: lantiq: Change variables to the same type as the source MIPS: lantiq: Move macro directly to iomem function mips: Remove q-accessors from non-64bit platforms FDDI: defza: Include linux/io-64-nonatomic-lo-hi.h MIPS: configs: Remove useless UEVENT_HELPER_PATH ...

clk: Remove io.h from clk-provider.h

2019-05-15T20:21:37Z

Now that we've gotten rid of clk_readl() we can remove io.h from the clk-provider header and push out the io.h include to any code that isn't already including the io.h header but using things like readl/writel, etc. Found with this grep: git grep -l clk-provider.h | grep '.c$' | xargs git grep -L 'linux/io.h' | \ xargs git grep -l \ -e '\<__iowrite32_copy\>' --or \ -e '\<__ioread32_copy\>' --or \ -e '\<__iowrite64_copy\>' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\<__devm_memremap_pages\>' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\<__io_aw\>' --or \ -e '\<__io_pbw\>' --or \ -e '\<__io_paw\>' --or \ -e '\<__io_pbr\>' --or \ -e '\<__io_par\>' --or \ -e '\<__raw_readb\>' --or \ -e '\<__raw_readw\>' --or \ -e '\<__raw_readl\>' --or \ -e '\<__raw_readq\>' --or \ -e '\<__raw_writeb\>' --or \ -e '\<__raw_writew\>' --or \ -e '\<__raw_writel\>' --or \ -e '\<__raw_writeq\>' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\<__io_virt\>' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\<__ioremap\>' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' I also reordered a couple includes when they weren't alphabetical and removed clk.h from kona, replacing it with clk-provider.h because that driver doesn't use clk consumer APIs.

MIPS: perf: ath79: Fix perfcount IRQ assignment

2019-04-16T22:09:10Z

Currently it's not possible to use perf on ath79 due to genirq flags mismatch happening on static virtual IRQ 13 which is used for performance counters hardware IRQ 5. On TP-Link Archer C7v5: CPU0 2: 0 MIPS 2 ath9k 4: 318 MIPS 4 19000000.eth 7: 55034 MIPS 7 timer 8: 1236 MISC 3 ttyS0 12: 0 INTC 1 ehci_hcd:usb1 13: 0 gpio-ath79 2 keys 14: 0 gpio-ath79 5 keys 15: 31 AR724X PCI 1 ath10k_pci $ perf top genirq: Flags mismatch irq 13. 00014c83 (mips_perf_pmu) vs. 00002003 (keys) On TP-Link Archer C7v4: CPU0 4: 0 MIPS 4 19000000.eth 5: 7135 MIPS 5 1a000000.eth 7: 98379 MIPS 7 timer 8: 30 MISC 3 ttyS0 12: 90028 INTC 0 ath9k 13: 5520 INTC 1 ehci_hcd:usb1 14: 4623 INTC 2 ehci_hcd:usb2 15: 32844 AR724X PCI 1 ath10k_pci 16: 0 gpio-ath79 16 keys 23: 0 gpio-ath79 23 keys $ perf top genirq: Flags mismatch irq 13. 00014c80 (mips_perf_pmu) vs. 00000080 (ehci_hcd:usb1) This problem is happening, because currently statically assigned virtual IRQ 13 for performance counters is not claimed during the initialization of MIPS PMU during the bootup, so the IRQ subsystem doesn't know, that this interrupt isn't available for further use. So this patch fixes the issue by simply booking hardware IRQ 5 for MIPS PMU.
