Merge tag 'sh-for-v6.14-tag1' of git://git.kernel.org/pub/scm/linux/k…

…ernel/git/glaubitz/sh-linux

Pull sh updates from John Paul Adrian Glaubitz:
 "Fixes and improvements for sh:

   - replace seq_printf() with the more efficient
     seq_put_decimal_ull_width() to increase performance when stress
     reading /proc/interrupts (David Wang)

   - migrate sh to the generic rule for built-in DTB to help avoid race
     conditions during parallel builds which can occur because Kbuild
     decends into arch/*/boot/dts twice (Masahiro Yamada)

   - replace select with imply in the board Kconfig for enabling
     hardware with complex dependencies. This addresses warnings which
     were reported by the kernel test robot (Geert Uytterhoeven)"

* tag 'sh-for-v6.14-tag1' of git://git.kernel.org/pub/scm/linux/kernel/git/glaubitz/sh-linux:
  sh: boards: Use imply to enable hardware with complex dependencies
  sh: Migrate to the generic rule for built-in DTB
  sh: irq: Use seq_put_decimal_ull_width() for decimal values
