drivers: Allow aspeed driver selection with COMPILE_TEST

2015-12-14T05:54:25+00:00

The patch doesn't fix PINCTRL_ASPEED as it's a not currently a useful configuration option. Signed-off-by: Andrew Jeffery

gpio: Add Aspeed AST2400 driver

2015-11-16T03:31:20+00:00

Fixes from Al: - Move aspeed Kconfig entry to correct menu. The Aspeed GPIO menu entry was added under "PCI GPIO expanders" which depends on PCI which may not be enabled for Aspeed. Move the entry to the "Memory mapped GPIO drivers" which describes the Aspeed GPIO driver more correctly. Fixes from jk: - Pass struct resource directly to devm_ioremap_resource - Expose entire bank as one gpio chip - Implement interrupts for GPIO banks. We have a set of interrupt registers in each bank; this change adds a gpio irqchip to hook them up to the GPIO code. - Don't set names for aspeed GPIOs. We need the numbers for exporting anyway. - Constify the aspeed_gpio_banks structure Signed-off-by: Joel Stanley Signed-off-by: Alistair Popple Signed-off-by: Jeremy Kerr

gpio: rcar: GPIO_RCAR doesn't relate to ARM

2015-09-14T07:12:03+00:00

8cd1470("gpio: rcar: Add r8a7795 (R-Car H3) support") added GPIO support for r8a7795. r8a7795 based on CONFIG_ARM64. OTOH, GPIO_RCAR driver can be compiled fine on non-ARM. This patch removed ARM dependency for it. Signed-off-by: Kuninori Morimoto Acked-by: Geert Uytterhoeven Acked-by: Simon Horman Signed-off-by: Linus Walleij

gpio: brcmstb: Add interrupt and wakeup source support

2015-08-13T11:13:26+00:00

Uses the gpiolib irqchip helpers. For this to work, the irq setup function is called once per bank instead of once per device. Note that all known uses of this block have a BCM7120 L2 interrupt controller as a parent. Supports interrupts for all GPIOs. In the IRQ handler, we check for raised IRQs for invalid GPIOs and warn (ratelimited) if they're encountered. Also, several drivers (e.g. gpio-keys) allow for GPIOs to be configured as wakeup sources, and this GPIO controller supports that through a separate interrupt path. The de-facto standard DT property "wakeup-source" is checked, since that indicates whether the GPIO controller hardware can wake. Uses the IRQCHIP_MASK_ON_SUSPEND irq_chip flag because UPG GIO doesn't have any of its own wakeup source configuration. Aside regarding gpiolib irqchip helpers: It wasn't obvious (to me) that you can have multiple chained irqchips and associated IRQ domains for a single parent IRQ, and as long as the xlate function is written correctly, a GPIO IRQ request end up checking the correct domain and will get associated with the correct IRQ. What helps make this clear is to read drivers/gpio/gpiolib-of.c: - of_gpiochip_find_and_xlate() - of_get_named_gpiod_flags() drivers/gpio/gpiolib.c: - gpiochip_find() Signed-off-by: Gregory Fong Reviewed-by: Florian Fainelli Signed-off-by: Linus Walleij

gpio: etraxfs: add interrupt support

2015-08-03T08:57:04+00:00

On ETRAX FS, all pins on the first port (and only the first port) have interrupt support. On ARTPEC-3, all pins on all ports have interrupt support. However, there are only eight interrupts. Each of the interrupts is associated with a group of pins and for each interrupt the one pin from the group which will trigger it can be selected.
