This makes the driver use the data pointer added to the gpio_chip to store a pointer to the state container instead of relying on container_of(). Cc: Feng Tang <feng.tang@intel.com> Signed-off-by: NLinus Walleij <linus.walleij@linaro.org>

The name .dev in a struct is normally reserved for a struct device that is let us say a superclass to the thing described by the struct. struct gpio_chip stands out by confusingly using a struct device *dev to point to the parent device (such as a platform_device) that represents the hardware. As we want to give gpio_chip:s real devices, this is not working. We need to rename this member to parent. This was done by two coccinelle scripts, I guess it is possible to combine them into one, but I don't know such stuff. They look like this: @@ struct gpio_chip *var; @@ -var->dev +var->parent and: @@ struct gpio_chip var; @@ -var.dev +var.parent and: @@ struct bgpio_chip *var; @@ -var->gc.dev +var->gc.parent Plus a few instances of bgpio that I couldn't figure out how to teach Coccinelle to rewrite. This patch hits all over the place, but I *strongly* prefer this solution to any piecemal approaches that just exercise patch mechanics all over the place. It mainly hits drivers/gpio and drivers/pinctrl which is my own backyard anyway.

CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

When I added the buslock/unlock mechanism to the pmic code in order to get rid of the horrible work queue stuff, stupid me missed to add the new callbacks to the irq_chip. In consequence Andrew removed the unused functions, but I missed that. Add them back and hook them up proper.

There is no need to install a chained handler for this hardware. This is a plain x86 IOAPIC interrupt which is handled by the core code perfectly fine. There is nothing special about demultiplexing these gpio interrupts which justifies a custom hack. Replace it by a plain old interrupt handler installed with request_irq. That makes the code agnostic about the underlying primary interrupt hardware. The overhead for this is minimal, but it gives us the advantage of accounting, balancing and to detect interrupt storms. gpio interrupts are not really that performance critical.

The set_type function of the pmic irq chip is a horrible hack. It schedules work because it cannot access the scu chip from the set_type function. That breaks the assumption, that the type is set after set_type has returned. irq_chips provide buslock functions to avoid the above. Convert the driver to use the proper model.

commit 456dc301([PATCH] intel_pmic_gpio: modify EOI handling following change of kernel irq subsystem) changes - desc->chip->eoi(irq); + + if (desc->chip->irq_eoi) + desc->chip->irq_eoi(irq_get_irq_data(irq)); + else + dev_warn(pg->chip.dev, "missing EOI handler for irq %d\n", irq); With the following explanation: "Latest kernel has many changes in IRQ subsystem and its interfaces, like adding irq_eoi" for struct irq_chip, this patch will make it support both the new and old interface." This is completely bogus. #1) The changelog does not match the patch at all #2) This driver relies on the assumption that it sits behind an eoi capable interrupt line. If the implementation of the underlying chip changes from eoi to irq_eoi then this driver has to follow that change and not add a total bogosity. Remove the sillyness and retrieve the interrupt data from irq_desc directly. No need to got through circles to look it up.

Moorestown has PMIC chip which contains GPIO blocks. The PMIC chip is connected to Langwell by SPI interface. So this GPIO driver will be regarded as SPI GPIO expander though the actual GPIO access is through IPC and SRAM. The SPI master contoller will probe this device driver by parsing SPIB table. Cleaned up for new IPC, GPE removed and some printk and other tidying by Alan Cox.
