2019-05-21treewide: Add SPDX license identifier for more missed filesThomas Gleixner
Add SPDX license identifiers to all files which: - Have no license information of any form - Have MODULE_LICENCE("GPL*") inside which was used in the initial scan/conversion to ignore the file These files fall under the project license, GPL v2 only. The resulting SPDX license identifier is: GPL-2.0-only Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2019-02-09Input: ili210x - fetch touchscreen geometry from DTMarek Vasut
Fetching the geometry from the ILI251x registers seems unreliable and sometimes returns all zeroes. Add support for fetching the geometry and axis inversion from DT instead. Signed-off-by: Marek Vasut <marex@denx.de> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2019-02-07Input: ili210x - switch to using devm_device_add_group()Dmitry Torokhov
By switching to devm_device_add_group() we can complete driver conversion to using managed resources and get rid of ili210x_i2c_remove(). Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2019-02-06Input: ili210x - add ILI251X supportMarek Vasut
Add support for ILI251x touch controller. This controller is similar to the ILI210x, except for the following differences: - Does not support I2C R-W transfer, Read must be followed by an obscenely long delay, and then followed by Write - Does support 10 simultaneous touch inputs. - Touch data format is slightly different, pressure reporting does not work although the touch data contain such information.

2019-02-06Input: ili210x - add OF match tableMarek Vasut
Add OF match table for the ili210x touchscreen. Signed-off-by: Marek Vasut <marex@denx.de> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2019-02-06Input: ili210x - reorder probeMarek Vasut
Perform the register access only after the I2C client data are set, this is only done in preparation for the subsequent patch which uses the I2C client data in the register IO function. Signed-off-by: Marek Vasut <marex@denx.de> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2019-02-06Input: ili210x - rework the touchscreen sample processingMarek Vasut
Get rid of the packed structures for representing data as that does not apply to other similar Ilitek touchscreens. Instead, implement a function which parses the data and reports touch events and coordinates. Signed-off-by: Marek Vasut <marex@denx.de> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2019-02-06Input: ili210x - convert to devm IRQMarek Vasut
Convert the driver to devm_request_irq(), drop the related unmanaged deregistration code and add ili210x_irq_teardown() to tear the IRQ down and cancel possible touchscreen pending work. Signed-off-by: Marek Vasut <marex@denx.de> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2019-02-06Input: ili210x - add reset GPIO supportMarek Vasut
The touchscreen can have a reset GPIO connected to it, add support for such an arrangement. Signed-off-by: Marek Vasut <marex@denx.de> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2019-02-06Input: ili210x - convert to devm_ functionsMarek Vasut
Convert the driver to dev-managed allocations. Signed-off-by: Marek Vasut <marex@denx.de> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2019-02-06Input: ili210x - drop get_pendown_stateMarek Vasut
The .get_pendown_state callback is set only by the platform data code, which was just removed. Thus, get_pendown_state() always returns false, so drop that altogether. Signed-off-by: Marek Vasut <marex@denx.de> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2019-02-06Input: ili210x - drop platform data supportMarek Vasut
There is not a single user of the ili210x platform data in the kernel, just drop it. Signed-off-by: Marek Vasut <marex@denx.de> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2017-01-22Input: touchscreen - drop unnecessary calls to input_set_drvdataGuenter Roeck
Since there is no call to dev_get_drvdata() or input_get_drvdata(), the call to input_set_drvdata() is unnecessary and can be dropped. Signed-off-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2017-01-21Input: touchscreen - use local variables consistentlyGuenter Roeck
If a function declares a variable to access a structure element, use it consistently. Signed-off-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2016-08-02Input: ili210x - fix permissions on "calibrate" attributeDmitry Torokhov
"calibrate" attribute does not provide "show" methods and thus we should not mark it as readable. Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

2013-12-06Input: use dev_get_platdata()Jingoo Han
Use the wrapper function for retrieving the platform data instead of accessing dev->platform_data directly. This is a cosmetic change to make the code simpler and enhance the readability.
