GPIO32 is a standard optional extension to the Xtensa architecture core that provides preconfigured output and input ports for intra SoC signaling. The GPIO32 option is implemented as 32bit Tensilica Instruction Extension (TIE) output state called EXPSTATE, and 32bit input wire called IMPWIRE. This driver treats input and output states as two distinct devices. v3: * Use BUG() in xtensa_impwire_set_value() to indicate that it should never be called (Linus Walleij) v2: * Address the comments of Linus Walleij: - Add a few comments - Expand commit log message - Use the BIT() macro for bit offsets - Rewrite CPENABLE handling as static inlines - Use device_initcall() * Depend on !SMP for reason explained in the comments (Marc Gauthier) * Use XCHAL_CP_ID_XTIOP to enable/disable GPIO32 only Signed-off-by: NBaruch Siach <baruch@tkos.co.il> Signed-off-by: NLinus Walleij <linus.walleij@linaro.org>

This patch adds support for the GPIOs found on the Fintek super-I/O chips F71882FG and F71889F. A super-I/O is a legacy I/O controller embedded on x86 motherboards. It is used to connect the low-bandwidth devices. Among others functions the F71882FG/F71889F provides: a parallel port, two serial ports, a keyboard controller, an hardware monitoring controller and some GPIO pins. Note that this super-I/Os are embedded on some Atom-based LaCie NASes. The GPIOs are used to control the LEDs and the hard drive power. Changes since v3: - Use request_muxed_region to protect the I/O ports against concurrent accesses. Changes since v2: - Remove useless NULL setters for driver data. Changes since v1: - Enhance the commit message by describing what is a Super-I/O. - Use self-explanatory names for the GPIO register macros. - Add a comment to explain the platform device and driver registration. - Fix gpio_get when GPIO is configured in input mode. I only had the hardware to check this mode recently... Signed-off-by: NSimon Guinot <simon.guinot@sequanux.org> Signed-off-by: NLinus Walleij <linus.walleij@linaro.org>

This makes it possible to enable the exynos platform as part of a multiplatform kernel, in addition to keeping the single-platform exynos support. The multiplatform variant has a number of limitations at the moment: * It only supports DT-enabled machines. This is not a problem in the long run, as non-DT machines for exynos are going away. The main problem here is that the gpio code and the exynos_eint irqchip are not multiplatform capable but still required for ATAGS based boot. * The watchdog driver is still missing a conversion. * sparsemem and memory_holes are currently not supported in multiplatform. The the multiplatform aware ARCH_EXYNOS Kconfig symbol is disabled for now, as dependent patches are still pending in other subsystem trees. We will enable it once everything comes together.

This patch is V3 of a GPIO driver for the R-Car series of SoCs from Renesas. This driver is designed to be reusable between multiple SoCs that share the same basic building block, but so far it has only been used on R-Car H1 (r8a7779). Each driver instance handles 32 GPIOs with individually maskable IRQs. The driver operates on a single I/O memory range and the 32 GPIOs are hooked up a single interrupt. In the case of R-Car H1 either external IRQ pins or GPIOs with interrupts can be used for on-board interupts. For external IRQs 4 pins are supported, and in the case of GPIO there are 202 GPIOS as 202 interrupts hooked up via 6 driver instances and to the GIC and the Cortex-A9 Quad. At this point this driver is interfacing as a regular platform device driver. In the future DT support will be submitted as an incremental feature patch.

This driver aims at replacing the arch/arm/plat-orion/gpio.c driver, and is designed to be compatible with all Marvell EBU SoCs: Orion, Kirkwood, Dove, Armada 370/XP and Discovery. It has been successfully tested on Dove and Armada XP at the moment. Compared to the plat-orion driver, this new driver has the following added benefits: *) Support for Armada 370 and Armada XP *) It is integrated with the mvebu pinctrl driver so that GPIO pins are properly muxed, and the GPIO driver knows which GPIO pins are output-only or input-only. *) Properly placed in drivers/gpio *) More extensible mechanism to support platform differences. The plat-orion driver uses a simple mask-offset DT property, which works fine for Discovery MV78200 but not for Armada XP.
