• 28538df03   gpio: mpc8xxx: don't allow input-only pins to be output for MPC5121 ... Browse Code »

  Add a 5121-custom reject if an input-only pin is requested to be output
  (see 18.3.1.1 in the refman). Also, rewrite mach-specific quirk setup to
  consume less lines which scales better.

• cfadd8385   powerpc/8xxx: Fix interrupt handling in MPC8xxx GPIO driver ... Browse Code »

  43

  Interrupt handler in MPC8xxx GPIO driver is missing the call to PIC EOI
  (end of interrupt) handler. As a result, at least on 85XX systems, GPIO
  interrupt is delivered only once. This patch adds the missing EOI call.
  Tested on custom P1022 board.

• 15a5148c6   powerpc/85xx: Add 'fsl,pq3-gpio' compatiable for GPIO driver ... Browse Code »

  Support MPC85xx platforms outside of MPC8572/MPC8536. The
  MPC8572/MPC8536 have an erratum that is worked around based on having
  "fsl,mpc8572-gpio" in the compatiable list. All other MPC85xx SoCs
  don't require this workaround and thus utilize the 'fsl,pq3-gpio'
  compatiable.

• c68308dd5   gpio: move mpc8xxx/512x gpio driver to drivers/gpio ... Browse Code »

  Move the driver to the place where it is expected to be nowadays. Also
  rename its CONFIG-name to match the rest and adapt the defconfigs.
  Finally, move selection of REQUIRE_GPIOLIB or WANTS_OPTIONAL_GPIOLIB to
  the platforms, because this option is per-platform and not per-driver.
