[PATCH 0/5] Add GPIO set_multiple callback support for ISA_BUS_API drivers

[William Breathitt Gray]

Most of the ISA_BUS_API drivers control GPIO via 8-bit ioport registers.
Since updating any given GPIO line involves writing out all 8 bits for
the respective register, it makes sense to add support for the GPIO
set_multiple callback function so that multiple GPIO lines may be set
more efficiently. This patchset adds such support in each respective
driver.

William Breathitt Gray (5):
  gpio: 104-dio-48e: Add set_multiple callback function support
  gpio: 104-idio-16: Add set_multiple callback function support
  gpio: gpio-mm: Add set_multiple callback function support
  gpio: ws16c48: Add set_multiple callback function support
  iio: stx104: Add GPIO set_multiple callback function support
