gpio_base was set to 0 if no system platform data or open firmware
platform data was provided. This led to conflicts, if any other gpiochip
with a gpiobase of 0 was instantiated already. Setting it to -1 will
automatically use the first one available.Signed-off-by: Hartmut Knaack

With commit f64ad1a0e21a, "gpio/omap: cleanup _set_gpio_wakeup(), remove
ifdefs", access to build time conditionally omitted 'suspend_wakeup'
member of the 'gpio_bank' structure has been placed unconditionally in
function _set_gpio_wakeup(), which is always built. This resulted in the
driver compilation broken for certain OMAP1, i.e., non-OMAP16xx,
configurations.Really required or not in previously excluded cases, define this
structure member unconditionally as a fix.Tested with a custom OMAP1510 only configuration.

Building a kernel with hotplug disabled results in a link failure:
`bgpio_remove' referenced in section `___ksymtab_gpl+bgpio_remove' of drivers/built-in.o: defined in discarded section `.devexit.text' of drivers/built-in.o
This is because of bgpio_remove() is exported. It is illegal to export
symbols which are discarded either at link time or as part of an
init/exit section.Fix this by dropping the __devexit attributation from bgpio_remove().
Also drop the __devinit attributation from bgpio_init().Signed-off-by: Russell King

Add i2c bindings for the mcp230xx devices. This is quite a lot simpler
than the spi one as there's no funky sub addressing done (one struct
i2c_client per struct gpio_chip).The mcp23s08_platform_data structure is reused for i2c, even though
only a single mcp23s08_chip_info structure is needed.To use, simply fill out a platform_data structure and pass it in
i2c_board_info, E.G.:static const struct mcp23s08_platform_data mcp23017_data = {
.chip[0] = {
.pullups = 0x00ff,
},
.base = 240,
};static struct i2c_board_info __initdata i2c_devs[] = {
{ I2C_BOARD_INFO("mcp23017", 0x20),
.platform_data = &smartview_mcp23017_data, },

The patch removes all the uses of cpu_is_mx(). Instead, it utilizes
platform_device_id to distinguish the different gpio types, IMX1_GPIO

i.mx SoCs.Signed-off-by: Shawn Guo

The wrong bit was masked when acking langwell gpio interrupts.
Reason for maskig the wrong bit was probably because__ffs() and ffs() functions
return bit indexes differently (0..31 vs 1..32)This fixes langwell based devices from hanging when a gpio interrupt is
triggered and undoes the breakage which occurred in change set

The bgpio_init() function does not initialise the shadow register for
the GPIO direction register. Thus, when configuring the first GPIO with
gpio_set_direction() all other GPIOs of the same bank will be
configured as inputs. Since the bgpio layer cannot know whether the
register is readable, the initialisation should be done by the caller
of bgpio_init().Also, the 'data' shadow variable that is used inside basic_mmio_gpio
to cache the current value of the GPIO_DR register is initialised from
the GPIO_PSR register within bgpio_init(). Thus when setting the
output value of a certain GPIO, the other GPIO outputs of the same
bank will be set or cleared depending on the pin state of the GPIO
inputs during bgpio_init().Signed-off-by: Lothar Waßmann

The property 'polarity' is handled by the GPIO core, and the 'gpio-base'
should be assigned automatically. It is meaningless in the device-tree,
since GPIO's are identified by the "chip-name"/offset pair.
This way, the whole pca953x_get_alt_pdata() can hopefully soon go away.
We still need to check whether we really want GPIO-interrupt functionality
by simply looking if the I2C node has an interrupts property defined, since
this property is not used for anything else.Signed-off-by: David Jander

In the case that we obtain device-tree data to fill in platform_data, the new
platform data struct was dynamically allocated, but the pointer to it was not
used everywhere it should. It seems easier to fix this issue by removing the
dynamic allocation altogether since its data is only used during driver
probing.Signed-off-by: David Jander

Remove cpu_is_* checks from gpio_show_revision() by passing in the
revision address offset from platform data. SoCs with no revision
register (15xx, 7xx, and all MPUIOs) use -1 (actually, USHRT_MAX) to
signify no register.While here, all GPIO banks are assumed to be the same revision, so fix
show_revision() to only show the revision for the first bank it finds.
This removes duplicate GPIO revision prints during boot.Thanks to Charulatha V for finding/fixing a few -1s
that were missed in the original patch.Signed-off-by: Kevin Hilman

Make _set_gpio_wakeup() generic by removing ifdefs. Code for the
various SoCs/bank-methods was already the same, except for the
non-wakeup GPIO checking. But that flag is set on a per-SoC basis, so

based on subtracting bank pointers.Signed-off-by: Kevin Hilman
