2011-07-08gpio/mxc: add device tree probe supportShawn Guo
The patch adds device tree probe support for gpio-mxc driver. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2011-07-08ARM: mxc: use ARCH_NR_GPIOS to define gpio numberShawn Guo
The patch removes MXC_GPIO_IRQS and instead uses ARCH_NR_GPIOS to define gpio number. This change is need when we change mxc gpio driver to be device tree aware. When migrating the driver to device tree, pdev->id becomes unusable. It requires driver get gpio range from gpio core, which will dynamically allocates number from ARCH_NR_GPIOS to 0. As a bonus point, it removes lines of '#if' and make the code a little bit cleaner. The side effect is the waste of number. But this is not a point when we go single image.

2011-07-08gpio/mxc: get rid of the uses of cpu_is_mx()Shawn Guo
The patch removes all the uses of cpu_is_mx(). Instead, it utilizes platform_device_id to distinguish the different gpio types, IMX1_GPIO on i.mx1, IMX21_GPIO on i.mx21 and i.mx27, IMX31_GPIO on all other i.mx SoCs.

2011-07-07gpio/mxc: add missing initialization of basic_mmio_gpio shadow variablesLothar Waßmann
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().

2011-07-05gpio/tegra: Use engineering names in DT compatible propertyStephen Warren
Engineering names are more stable than marketing names. Hence, use them for Device Tree compatible properties instead. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2011-06-28of/gpio: Add new method for getting gpios under different property namesJohn Bonesio
This patch adds a new routine, of_get_named_gpio_flags(), which takes the property name as a parameter rather than assuming "gpios". of_get_gpio_flags() is modified to call of_get_named_gpio_flags() with "gpios" as the property parameter.

2011-06-16gpio/ml-ioh: fix off-by-one for displaying variable i in dev_errAxel Lin
with the "for (; i != 0; i--)" sytax, i-- will be executed after the iteration. thus dev_err shows wrong i value. Switch to "while(--i >= 0)" which is better in readability. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2011-06-16gpio/pca953x: Deprecate meaningless device-tree bindingsDavid Jander
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.

2011-06-16gpio/pca953x: Remove dynamic platform data pointerDavid 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.

2011-06-16gpio/pca953x: Fix IRQ support.David Jander
It seems that in the normal case, IRQ_NOREQUEST needs to be explicitly cleared, otherwise claiming the interrupt fails. In the case of sparse interrupts, the descriptor needs to be allocated first.

2011-06-16gpio/omap: cleanup show revision, remove cpu_is checks, display only onceKevin Hilman
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 <charu@ti.com> for finding/fixing a few -1s that were missed in the original patch. Signed-off-by: Kevin Hilman <khilman@ti.com>
2011-06-16gpio/omap: debounce remove SoC specific registers, use pdataKevin Hilman
Use register offsets passed in from pdata for accessing debounce registers. Signed-off-by: Kevin Hilman <khilman@ti.com>
2011-06-16gpio/omap: cleanup _set_gpio_wakeup(), remove ifdefsKevin 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 can be used for all SoCs. While here, use dev_err() and remove GPIO bank calculation assumption based on subtracting bank pointers. Signed-off-by: Kevin Hilman <khilman@ti.com>
2011-06-16gpio/omap: remove useless gpio_valid() & check_gpio() checksKevin Hilman
These functions are useless. They are only called in a few places, and where they are called, the GPIO has already been converted from an IRQ or masked, so these functions will never fail. Signed-off-by: Kevin Hilman <khilman@ti.com>
2011-06-16gpio/omap: convert MPUIO IRQ over to generic irq_chipKevin Hilman
MPUIO banks have their own dedicated IRQ chip interface, separate from the "normal" GPIO banks. Convert the MPUIO IRQ chip over to using the new generic IRQ chip interface. Signed-off-by: Kevin Hilman <khilman@ti.com>
2011-06-16gpio/omap: conslidate enable/disable of GPIO IRQs, remove ifdefsKevin Hilman
Cleanup GPIO IRQ enable/disable handling by removing SoC-specific Also split enable/disable IRQ into separate functions for better readability and also facilitate potentially moving to generic irq_chip in the future. Signed-off-by: Kevin Hilman <khilman@ti.com>
2011-06-16gpio/omap: consolidate IRQ status handling, remove #ifdefsKevin Hilman
Cleanup IRQ status handling by passing IRQ status register offsets via platform data. Cleans up clearing of GPIO IRQ status and GPIO ISR handler. Signed-off-by: Kevin Hilman <khilman@ti.com>
2011-06-16gpio/omap: consolidate direction, input, output, remove #ifdefsKevin Hilman
Add register offset fields to GPIO platform_data for registers. This patch adds registers that control direction, input and output data. Using these register offsets in the common driver allows removal of #ifdefs and greatly improves readability. Also create dedicated data out functions: one for banks with dedicated set/clear registers, and another for banks with a single mask register. Signed-off-by: Kevin Hilman <khilman@ti.com>

2011-06-16gpio/omap: replace get_gpio_index() by using bank widthKevin Hilman
The get_gpio_index() function, littered with cpu_is_* checks can be easily replaced by using bitops based on the GPIO bank width. Do so. Signed-off-by: Kevin Hilman <khilman@ti.com>
2011-06-16gpio/omap: _get_gpio_irqbank_mask: replace hard-coded mask with bank->widthKevin Hilman
Replace hard-coded mask values with bank->width which is already coming from platform_data. Signed-off-by: Kevin Hilman <khilman@ti.com>
2011-06-16gpio/omap: move bank width into struct gpio_bankKevin Hilman
Rather than having a file-global bank_width variable, move it into struct gpio_bank so it can be bank-specific. Note the bank width is already passed per-bank via platform_data, so current code would be incorrect if any banks had different width. Signed-off-by: Kevin Hilman <khilman@ti.com>
2011-06-16gpio/omap: remove MPUIO handling from _clear_gpio_irqbank()Kevin Hilman
Remove the OMAP1 #ifdef and MPUIO special case for _clear_gpio_irqbank() The MPUIOs do not need a register access to ack/clear the IRQ status, since reading the IRQ status clears it. In addition, the MPUIO irq_chip has an empty ack method, so _clear_gpio_irqbank() is never used for MPUIOs. Signed-off-by: Kevin Hilman <khilman@ti.com>
2011-06-16gpio/omap: _clear_gpio_irqbank: fix flushing of posted writeKevin Hilman
In commit 78a1a6d3411de1a8b0dc1cb92754b5f12f251912 (ARM: OMAP4: Update the GPIO support) braces were mistakenly added to included the register read-back inside the cpu_is_* checking. Remove the braces, ensuring that a register read-back is done, even when the IRQSTATUS2 register is not written. Note that the register read-back might be IRQSTATUS1 or IRQSTATUS2 depending on the CPU, but a read-back of any register in that region will cause a flush of the posted writes.
