Add F81866 GPIO supports
Fintek F81866 is a SuperIO. It contains HWMON/GPIO/Serial Ports.
and it has totally 72(9x8 sets) gpio pins.Here is the PDF spec:
http://www.alldatasheet.com/datasheet-pdf/pdf/459085/FINTEK/F81866AD-I.htmlThe control method is the same with F7188x, but we should care the address
of GPIO8x.GPIO address is below:
GPIO0x based: 0xf0
GPIO1x based: 0xe0
GPIO2x based: 0xd0
GPIO3x based: 0xc0
GPIO4x based: 0xb0
GPIO5x based: 0xa0
GPIO6x based: 0x90
GPIO7x based: 0x80
GPIO8x based: 0x88

to store a pointer to the state container instead of relying on

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->parentand:
@@
struct gpio_chip var;
@@
-var.dev
+var.parentand:
@@
struct bgpio_chip *var;
@@
-var->gc.dev
+var->gc.parentPlus 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.Cc: Haavard Skinnemoen

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: Simon Guinot
