Subject: [PATCH RFC char-misc-next 0/5] misc: microchip: pci1xxxx: Add auxiliary bus driver and the GPIO driver for PIO function of pci1xxxx.
Date: Thu, 4 Aug 2022 22:02:14 +0530 [thread overview]
Message-ID: <20220804163219.921640-1-kumaravel.thiagarajan@microchip.com> (raw)
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.
