menu "GPIO Support"
config DM_GPIO
bool "Enable Driver Model for GPIO drivers"
depends on DM
help
Enable driver model for GPIO access. The standard GPIO
interface (gpio_get_value(), etc.) is then implemented by
the GPIO uclass. Drivers provide methods to query the
particular GPIOs that they provide. The uclass interface
is defined in include/asm-generic/gpio.h.
config ALTERA_PIO
bool "Altera PIO driver"
depends on DM_GPIO
help
Select this to enable PIO for Altera devices. Please find
details on the "Embedded Peripherals IP User Guide" of Altera.
config DWAPB_GPIO
bool "DWAPB GPIO driver"
depends on DM && DM_GPIO
default n
help
Support for the Designware APB GPIO driver.
config ATMEL_PIO4
bool "ATMEL PIO4 driver"
depends on DM
default n
help
Say yes here to support the Atmel PIO4 driver.
The PIO4 is new version of Atmel PIO controller, which manages
up to 128 fully programmable input/output lines. Each I/O line
may be dedicated as a general purpose I/O or be assigned to
a function of an embedded peripheral.
config INTEL_BROADWELL_GPIO
bool "Intel Broadwell GPIO driver"
depends on DM
help
This driver supports Broadwell U devices which have an expanded
GPIO feature set. The difference is large enough to merit a separate
driver from the common Intel ICH6 driver. It supports a total of
95 GPIOs which can be configured from the device tree.
config LPC32XX_GPIO
bool "LPC32XX GPIO driver"
depends on DM
default n
help
Support for the LPC32XX GPIO driver.
config MSM_GPIO
bool "Qualcomm GPIO driver"
depends on DM_GPIO
default n
help
Support GPIO controllers on Qualcomm Snapdragon family of SoCs.
This controller have single bank (default name "soc"), every
gpio has it's own set of registers.
Only simple GPIO operations are supported (get/set, change of
direction and checking pin function).
Supported devices:
- APQ8016
- MSM8916
config PM8916_GPIO
bool "Qualcomm PM8916 PMIC GPIO/keypad driver"
depends on DM_GPIO && PMIC_PM8916
help
Support for GPIO pins and power/reset buttons found on
Qualcomm PM8916 PMIC.
Default name for GPIO bank is "pm8916".
Power and reset buttons are placed in "pm8916_key" bank and
have gpio numbers 0 and 1 respectively.
config ROCKCHIP_GPIO
bool "Rockchip GPIO driver"
depends on DM_GPIO
help
Support GPIO access on Rockchip SoCs. The GPIOs are arranged into
a number of banks (different for each SoC type) each with 32 GPIOs.
The GPIOs for a device are defined in the device tree with one node
for each bank.
config SANDBOX_GPIO
bool "Enable sandbox GPIO driver"
depends on SANDBOX && DM && DM_GPIO
help
This driver supports some simulated GPIOs which can be adjusted
using 'back door' functions like sandbox_gpio_set_value(). Then the
GPIOs can be inspected through the normal get_get_value()
interface. The purpose of this is to allow GPIOs to be used as
normal in sandbox, perhaps with test code actually driving the
behaviour of those GPIOs.
config SANDBOX_GPIO_COUNT
int "Number of sandbox GPIOs"
depends on SANDBOX_GPIO
default 128
help
The sandbox driver can support any number of GPIOs. Generally these
are specified using the device tree. But you can also have a number
of 'anonymous' GPIOs that do not belong to any device or bank.
Select a suitable value depending on your needs.
config GPIO_UNIPHIER
bool "UniPhier GPIO"
depends on ARCH_UNIPHIER
help
Say yes here to support UniPhier GPIOs.
config VYBRID_GPIO
bool "Vybrid GPIO driver"
depends on DM
default n
help
Say yes here to support Vybrid vf610 GPIOs.
config PIC32_GPIO
bool "Microchip PIC32 GPIO driver"
depends on DM_GPIO && MACH_PIC32
default y
help
Say yes here to support Microchip PIC32 GPIOs.
config MVEBU_GPIO
bool "Marvell MVEBU GPIO driver"
depends on DM_GPIO && ARCH_MVEBU
default y
help
Say yes here to support Marvell MVEBU (Armada XP/38x) GPIOs.
config ZYNQ_GPIO
bool "Zynq GPIO driver"
depends on DM_GPIO && (ARCH_ZYNQ || ARCH_ZYNQMP)
default y
help
Supports GPIO access on Zynq SoC.
