Subject: [PATCH 0/7] gpio: move ppc4xx driver to drivers/gpio and modernize
Date: Mon, 1 Jun 2026 22:01:24 -0700 [thread overview]
Message-ID: <20260602050131.856789-1-rosenp@gmail.com> (raw)
This series moves the ppc4xx GPIO driver from arch/powerpc to
drivers/gpio, converts it to be a proper platform driver using
generic MMIO helpers, drops architecture-specific accessors, and
prepares it for module build and COMPILE_TEST.
Patches 1-4 move the driver and convert it to standard platform
driver infrastructure. Patch 5 switches to generic MMIO helpers.
Patch 6 drops PPC-specific IO accessors and enables COMPILE_TEST.
Patch 7 adds the missing MODULE metadata so the driver can actually
be built as a module.
