Adds a new driver for Altera soft GPIO IP. The driver is able to do read/write and allows GPIO to be a interrupt controller. Tested on Altera GHRD on interrupt handling and IO. v10: - Updated conflicting device tree parameters - Removed unused headers - Used macro instead of magic numbers for ngpio - Code readability cleanup using ?: and temporal variables - Removed leftover garbage and unnecessary function calls - Checked bgpio_init but unusable because Altera GPIO may not be a multiple of 8 bits v9: - Removed duplicated initialization on set_type using temporals to improve code readability in calling generic_handle_irq - Using ?: ternary to reduce code size v8: - Using for_each_set_bit - Added const for struct definition - Removed naggy pr_err - Sort alpha header - Remove unused macros - Use fixed width data types instead of unsigned long - Whitespace issue fixes - Removed _relaxed function for better compatibility across different CPU - Changed irq_create_mapping to platform_get_irq updated implementation to use gpiochip_irqchip_add - Reserve interrupt-cells number 2 in device tree binding for future use - Remove confusing sections on devicetree bindings - Added tristate Kconfig help text v7: - Used dev_warn instead of pr_warn - Clean up unnecesarry if else indentation v6: - Added irq_startup and irq_shutdown - Changed bitwise clamping style - Cleanup bitwise operation to improve readability change naming of mapped irqs from virq to mapped_irq v5: - Dispose irq_domain mapping correctly - Update optional binding description in binding docs v4: - Added vendor prefix to devicetree binding for IP specific properties using MMIO GPIO helper library instead of manually map PIO to memory - altera_gpio_chip inline struct documentation to kerneldoc - Using dev_ print to print a better failure message v2, v3: - Do not reference NO_IRQ - Updated irq_set_type to only allow the hardware configured irq type Signed-off-by: Tien Hock Loh <thloh@altera.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
