The driver clears the general configuration register during the remove() hook. This should also be done in case the driver exits on error. This change move the clear of that register to the devm_add_action_or_reset() hook. Signed-off-by:

This change makes use of the devm_gpiochip_add_data() function. With this the gpiochip_remove() function can be removed, and the adp5589_gpio_remove() function as well. The kpad->export_gpio variable is also redundant now, and has been removed. Signed-off-by:

This is currently just dead code. It's from around a time when platform-data was used, and a board could hook it's own special callback for setup/teardown, and a private object (via 'context'). This change removes it, as there are no more users in mainline for this. Signed-off-by:

This change makes use of the devm_input_allocate_device() function, which gets rid of the input_free_device() and input_unregister_device() calls. When a device is allocated via input_allocate_device(), the input_register_device() call will also be device-managed, so there is no longer need to manually call unregister. Also, the irq is allocated with the devm_request_threaded_irq(), so with these two changes, the adp5589_keypad_remove() function is no longer needed. This cleans up the error & exit paths.

This removes the need to manually free the kpad object and cleans up some exit/error paths. The error path cleanup should reduce the risk of any memory leaks with this object. Signed-off-by:

This adds the code for the Atmel touchscreens such as mXT224 to obtain power regulators for the supply voltages AVDD and VDD. On mobile phones such as Samsung GT-I8190 (Golden) this is needed to explicitly bring power online. We just enable the regulators at probe() and disable them at remove() or in the error path for now. As regulators are naturally stubbed if not available, this should have no impact on existing systems. Signed-off-by:

This driver uses GPIO descriptors to drive the touchscreen RESET line. In the existing device trees this has in conflict with intution been flagged as GPIO_ACTIVE_HIGH and the driver then applies the reverse action by driving the line low (setting to 0) to enter reset state and driving the line high (setting to 1) to get out of reset state. The correct way to handle active low GPIO lines is to provide the GPIO_ACTIVE_LOW in the device tree (thus properly describing the hardware) and letting the GPIO framework invert the assertion (driving high) to a low level and vice versa. This is considered a bug since the device trees are incorrectly mis-specifying the line as active high. Fix the driver and all device trees specifying a reset line. Signed-off-by:

This is essentially a revert of: 3ac8bf07 ("[PATCH] ads7846: sparc32 warning fix") By now enable_irq() and disable_irq() are properly defined in linux/interrupt.h and we do not need to pull in architecture-specific bits. Signed-off-by:

In some rare cases the 32 bit Rt value will overflow if z2 and x is max, z1 is minimal value and x_plate_ohms is relatively high (for example 800 ohm). This would happen on some screen age with low pressure. There are two possible fixes: - make Rt 64bit - reorder calculation to avoid overflow The second variant seems to be preferable, since 64 bit calculation on 32 bit system is a bit more expensive.

Starting with 3eac5c7e ("Input: ads7846 - extend the driver for ads7845 controller support"), the ads7845 was partially converted to full duplex mode. Since it is not touchscreen controller specific, it is better to extend this conversion to cover entire driver. This will reduce CPU load and make driver more readable. Signed-off-by:

Hard-coding resolution for st1633 device was wrong. Some of LCDs like YTS700TLBC-02-100C has assembled Sitronix st1633 touchcontroller too. But the resolution is not 320x480 as was hard-coded. Add new function which reads correct resolution directly from register. Signed-off-by:
