This patch adds the field definitions for the SPI_SR register. The SPI status register is write-1-to-clear and this value is written at init time.

Rename this function to of_spi_get_gpio_numbers() as this is what the function does, it does not register a master, it is called in the path of registering a master so the name is logical in a convoluted way, but it is better to follow Rusty Russell's ABI level no 7: "The obvious use is (probably) the correct one" Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Link: https://lore.kernel.org/r/20190808150321.23319-1-linus.walleij@linaro.orgSigned-off-by: Mark Brown <broonie@kernel.org>

We don't need dev_err() messages when platform_get_irq() fails now that platform_get_irq() prints an error message itself when something goes wrong. Let's remove these prints with a simple semantic patch. // <smpl> @@ expression ret; struct platform_device *E; @@ ret = ( platform_get_irq(E, ...) | platform_get_irq_byname(E, ...) ); if ( \( ret < 0 \| ret <= 0 \) ) { ( -if (ret != -EPROBE_DEFER) -{ ... -dev_err(...); -... } | ... -dev_err(...); ) ... } // </smpl> While we're here, remove braces on if statements that only have one statement (manually).

The SPI thingies request FIFO-99 by default, reduce this to FIFO-50. FIFO-99 is the very highest priority available to SCHED_FIFO and it not a suitable default; it would indicate the SPI work is the most important work on the machine.

Now Spreadtrum ADI controller supplies multiple master accessing channel to support multiple subsystems accessing, instead of using a hardware spinlock to synchronize between the multiple subsystems. To keep backward compatibility, we should change the hardware spinlock to be optional. Moreover change to use of_hwspin_lock_get_id() function which return -ENOENT error number to indicate no hwlock support.

When the system was rebooted by watchdog, now we did not save the watchdog reset mode which will make system enter a incorrect mode after rebooting. Thus we should set the watchdog reset mode as default when opening the watchdog configuration, that means if the system was rebooted by other reason through the restart_handler(), then we will clear the default watchdog reset mode to save the correct reset mode.

Matching on the 'cpus' node was a bad choice because the schema is incorrectly applied to non-RiscV cpus nodes. As we now have a common cpus schema which checks the general structure, it is also redundant to do so in the Risc-V CPU schema. The downside is one could conceivably mix different architecture's cpu nodes or have typos in the compatible string. The latter problem pretty much exists for every schema.

Pull perf tooling updates from Thomas Gleixner: "A set of perf improvements and fixes: perf db-export: - Improvements in how COMM details are exported to databases for post processing and use in the sql-viewer.py UI. - Export switch events to the database. BPF: - Bump rlimit(MEMLOCK) for 'perf test bpf' and 'perf trace', just like selftests/bpf/bpf_rlimit.h do, which makes errors due to exhaustion of this limit, which are kinda cryptic (EPERM sometimes) less frequent. perf version: - Fix segfault due to missing OPT_END(), noticed on PowerPC. perf vendor events: - Add JSON files for IBM s/390 machine type 8561. perf cs-etm (ARM): - Fix two cases of error returns not bing done properly: Invalid ERR_PTR() use and loss of propagation error codes" * 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (28 commits) perf version: Fix segfault due to missing OPT_END() perf vendor events s390: Add JSON files for machine type 8561 perf cs-etm: Return errcode in cs_etm__process_auxtrace_info() perf cs-etm: Remove errnoeous ERR_PTR() usage in cs_etm__process_auxtrace_info perf scripts python: export-to-postgresql.py: Export switch events perf scripts python: export-to-sqlite.py: Export switch events perf db-export: Export switch events perf db-export: Factor out db_export__threads() perf script: Add scripting operation process_switch() perf scripts python: exported-sql-viewer.py: Use new 'has_calls' column perf scripts python: exported-sql-viewer.py: Remove redundant semi-colons perf scripts python: export-to-postgresql.py: Add has_calls column to comms table perf scripts python: export-to-sqlite.py: Add has_calls column to comms table perf db-export: Also export thread's current comm perf db-export: Factor out db_export__comm() perf scripts python: export-to-postgresql.py: Export comm details perf scripts python: export-to-sqlite.py: Export comm details perf db-export: Export comm details perf db-export: Fix a white space issue in db_export__sample() perf db-export: Move export__comm_thread into db_export__sample() ...

Pull core fixes from Thomas Gleixner: - A collection of objtool fixes which address recent fallout partially exposed by newer toolchains, clang, BPF and general code changes. - Force USER_DS for user stack traces [ Note: the "objtool fixes" are not all to objtool itself, but for kernel code that triggers objtool warnings. Things like missing function size annotations, or code that confuses the unwinder etc. - Linus] * 'core-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (27 commits) objtool: Support conditional retpolines objtool: Convert insn type to enum objtool: Fix seg fault on bad switch table entry objtool: Support repeated uses of the same C jump table objtool: Refactor jump table code objtool: Refactor sibling call detection logic objtool: Do frame pointer check before dead end check objtool: Change dead_end_function() to return boolean objtool: Warn on zero-length functions objtool: Refactor function alias logic objtool: Track original function across branches objtool: Add mcsafe_handle_tail() to the uaccess safe list bpf: Disable GCC -fgcse optimization for ___bpf_prog_run() x86/uaccess: Remove redundant CLACs in getuser/putuser error paths x86/uaccess: Don't leak AC flag into fentry from mcsafe_handle_tail() x86/uaccess: Remove ELF function annotation from copy_user_handle_tail() x86/head/64: Annotate start_cpu0() as non-callable x86/entry: Fix thunk function ELF sizes x86/kvm: Don't call kvm_spurious_fault() from .fixup x86/kvm: Replace vmx_vmenter()'s call to kvm_spurious_fault() with UD2 ...
