      gpio: pca953x: make inclusion of <linux/of_platform.h> unconditional · c2369d3f
      Linus Walleij authored
      After adding the DT matching in
      commit 6f29c9af
      "gpio: pca935x: fix of-only probed devices"
      compilation fails like this:
      
      CC [M]  drivers/gpio/gpio-pca953x.o
      gpio-pca953x.c: In function ‘pca953x_probe’:

      cc1: some warnings being treated as errors
      ../scripts/Makefile.build:264: recipe for target
      'drivers/gpio/gpio-pca953x.o' failed
      
      After removing the conditional inclusion guards compilation
      works fine again. Might be a module problem so that
      fix.

      Ben Dooks authored
      If the pca953x device is probed from OF using the proper OF probing then
      the i2c-client will be NULL and the device probe will fail as id is NULL
      and it isn't an ACPI device (previous drivers would simply OOPS out).
      
      Add support for the of_device_id table having the same data as the others
      so that the correct paths will be taken when registering a device.
      
      An example of current valid of node which did not work:
      
      	gpio@38 {
      		compatible = "onsemi,pca9654", "nxp,pca9534";
      		reg = <0x38>;
      		interrupt-parent = <&gpio5>;
      		interrupts = <25 IRQ_TYPE_LEVEL_LOW>;
      	};

      gpio: pca953x: add onsemi,pca9654 id · 9f49f6dd
      Ben Dooks authored
      Add onsemi,pca9654 which is also compatible with the nxp,pca9524 as it
      is an 8bit expander with an interrupt output.

      gpio: Add GPIO support for the ACCES 104-IDI-48 · 6ddcf9b4
      William Breathitt Gray authored
      The ACCES 104-IDI-48 family of PC/104 utility boards feature 48
      individually optically isolated digital inputs. Enabled inputs feature
      change-of-state detection capability; if change-of-state detection is
      enabled, an interrupt is fired off if a change of input level
      (low-to-high or high-to-low) is detected. Change-of-state IRQs are
      enabled/disabled on 8-bit boundaries, for a total of six boundaries.
      
      This driver provides GPIO and IRQ support for these 48 channels of
      digital input. The base port address for the device may be configured
      via the idi_48_base module parameter. The interrupt line number for the
      device may be configured via the idi_48_irq module parameter.

      Linus Torvalds authored
      Pull perf updates from Thomas Gleixner:
       "Mostly updates to the perf tool plus two fixes to the kernel core code:
      
         - Handle tracepoint filters correctly for inherited events (Peter
           Zijlstra)
      
         - Prevent a deadlock in perf_lock_task_context (Paul McKenney)
      
         - Add missing newlines to some pr_err() calls (Arnaldo Carvalho de
           Melo)
      
         - Print full source file paths when using 'perf annotate --print-line
           --full-paths' (Michael Petlan)
      
         - Fix 'perf probe -d' when just one out of uprobes and kprobes is
           enabled (Wang Nan)
      
         - Add compiler.h to list.h to fix 'make perf-tar-src-pkg' generated
           tarballs, i.e. out of tree building (Arnaldo Carvalho de Melo)
      
         - Add the llvm-src-base.c and llvm-src-kbuild.c files, generated by
           the 'perf test' LLVM entries, when running it in-tree, to
           .gitignore (Yunlong Song)
      
         - libbpf error reporting improvements, using a strerror interface to
           more precisely tell the user about problems with the provided
           scriptlet, be it in C or as a ready made object file (Wang Nan)
      
         - Do not be case sensitive when searching for matching 'perf test'
           entries (Arnaldo Carvalho de Melo)
      
         - Inform the user about objdump failures in 'perf annotate' (Andi
           Kleen)
      
         - Improve the LLVM 'perf test' entry, introduce a new ones for BPF
           and kbuild tests to check the environment used by clang to compile
           .c scriptlets (Wang Nan)"
