      of: unittest: Disable interrupt node tests for old world MAC systems · da08d8cb
      Guenter Roeck authored
      On systems with OF_IMAP_OLDWORLD_MAC set in of_irq_workarounds, the
      devicetree interrupt parsing code is different, causing unit tests of
      devicetree interrupt nodes to fail. Due to a bug in unittest code, which
      tries to dereference an uninitialized pointer, this results in a crash.

      The problem was observed when running a qemu test for the g3beige machine
      with devicetree unittests enabled.
      
      Disable interrupt node tests on affected systems to avoid both false
      unittest failures and the crash.
      
      With this patch in place, unittest on the affected system passes with
      the following message.
      
      	dt-test ### end of unittest - 144 passed, 0 failed

      scripts/dtc: Update to upstream version v1.4.7-14-gc86da84d30e4 · f858927f
      Rob Herring authored
      Major changes are I2C and SPI bus checks, YAML output format (for
      future validation), some new libfdt functions, and more libfdt
      validation of dtbs.
      
      The YAML addition adds an optional dependency on libyaml. pkg-config is
      used to test for it and pkg-config became a kconfig dependency in 4.18.
      
      This adds the following commits from upstream:

      Merge tag 'omap-for-v4.19/fixes-v2-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
      
      Fixes for omap variants against v4.19-rc1
      
      These are mostly fixes related to using ti-sysc interconnect target module
      driver for accessing right register offsets for sgx and cpsw and for
      no_console_suspend regression.
      
      There is also a droid4 emmc fix where emmc may not get detected for some
      models, and vibrator dts mismerge fix.
      
      And we have a file permission fix for am335x-osd3358-sm-red.dts that
      just got added. And we must tag RTC as system-power-controller for
      am437x for PMIC to shut down during poweroff.
