[PATCH v1 char-misc-next 0/5] misc: microchip: pci1xxxx: Add auxiliary bus driver and the GPIO driver for PIO function of pci1xxxx.

[Kumaravel Thiagarajan]

pci1xxxx is a PCIe switch with a multi-function endpoint on one of its
downstream ports. PIO function is one of the functions in the
multi-function endpoint. PIO function combines a GPIO controller and also
an interface to program pci1xxxx'x OTP & EEPROM. This patch adds an
auxiliary bus driver that enumerates separate child devices for gpio and
OTP/EEPROM interface and the gpio controller driver for the first child.

Kumaravel Thiagarajan (5):
  misc: microchip: pci1xxxx: load auxiliary bus driver for the PIO
    function in the multi-function endpoint of pci1xxxx device.
  misc: microchip: pci1xxxx: load gpio driver for the gpio controller
    auxiliary device enumerated by the auxiliary bus driver.
  misc: microchip: pci1xxxx: Add functions to configure gpio pins as
    input / output, get status, handle I/O for gpio pins.
  misc: microchip: pci1xxxx: Add gpio irq handler and irq helper
    functions irq_ack, irq_mask, irq_unmask and irq_set_type of
    irq_chip.
  misc: microchip: pci1xxxx: Add power management functions - suspend &
    resume handlers.
