* gpiolib: use gpio_chips list in gpiochip_find_baseAlexandre Courbot2013-02-09
| | | | | | | | | | | | | | Re-implement gpiochip_find_base using the list of chips instead of the global gpio_desc[] array. This makes it both simpler and more efficient, and is needed to remove the global descriptors array. The new code should preserve the exact same GPIO number assignment policy as the code it is replacing. There shouldn't be any visible change to the assigned GPIO numbers.

* gpiolib: link all gpio_chips using a listAlexandre Courbot2013-02-09
| | | | | | | | | | | | | | | Add a list member to gpio_chip that allows all chips to be parsed quickly. The current method requires parsing the entire GPIO integer space, which is painfully slow. Using a list makes many chip operations that involve lookup or parsing faster, and also simplifies the code. It is also necessary to eventually get rid of the global gpio_desc[] array. The list of gpio_chips is always ordered by base GPIO number to ensure chips traversal is done in the right order.

| * gpio: mpc8xxx: don't set IRQ_TYPE_NONE when creating irq mappingAnatolij Gustschin2013-02-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Exporting gpios over sysfs GPIO interface throws genirq error messages, i.e. on an mpc5121 based board exporting GPIO 5 triggers it: # echo 229 > /sys/class/gpio/export genirq: Setting trigger mode 0 for irq 44 failed (mpc512x_irq_set_type+0x0/0x18c) Similar error messages appear in the kernel boot log since the board specifies GPIOs for matrix keypad and also SD Card write protect and card detect GPIOs in its device tree. For all these GPIOs there is an error message in the log. The issue is triggered by setting the irq type to IRQ_TYPE_NONE in the driver's irq_domain map function mpc8xxx_gpio_irq_map(). ... mpc8xxx_gpio_irq_map irq_set_irq_type __irq_set_trigger __irq_set_trigger() calls irq_set_type() callback of the mpc8xxx gpio irq chip with the IRQ_TYPE_NONE in its 'flags' argument. This callback is either mpc8xxx_irq_set_type() or mpc512x_irq_set_type(). Both these functions return -EINVAL in the case if IRQ_TYPE_NONE is passed in the flow_type argument. This return value triggers the observed error message in __irq_set_trigger(). Modifying these callbacks to not return an error in IRQ_TYPE_NONE case doesn't make any sense to me. The line setting IRQ_TYPE_NONE type has been originally added by commit 345e5c8a "powerpc: Add interrupt support to mpc8xxx_gpio". At this time set_irq_type() checked its type argument and returned 0 if the type argument didn't specify any meaningful type in its type sense bits (and thus was equal to IRQ_TYPE_NONE). Effectively this line was a nop and I wonder what was the point of adding it. Remove IRQ_TYPE_NONE setting in the irq_domain mapping function.

New expanders from the pca53x family come with 40 GPIOs which no more fit in a 32 variable. This patch make access to the registers more generic by relying on an array of u8 variables. This fits exactly the way the registers are represented in the hardware. It also adds helpers to access to a single register of a bank instead of reading or writing all the banks for a given register.

| * gpio: devm_gpio_* support should not depend on GPIOLIBShawn Guo2013-01-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some architectures (e.g. blackfin) provide gpio API without requiring GPIOLIB support (ARCH_WANT_OPTIONAL_GPIOLIB). devm_gpio_* functions should also work for these architectures, since they do not really depend on GPIOLIB. Add a new option GPIO_DEVRES (enabled by default) to control the build of devres.c. It also removes the empty version of devm_gpio_* functions for !GENERIC_GPIO build from linux/gpio.h, and moves the function declarations from asm-generic/gpio.h into linux/gpio.h.
