2019-08-14Input: remove dev_err() usage after platform_get_irq()Stephen Boyd
We don't need dev_err() messages when platform_get_irq() fails now that platform_get_irq() prints an error message itself when something goes wrong. Let's remove these prints with a simple semantic patch. // <smpl> @@ expression ret; struct platform_device *E; @@ ret = ( platform_get_irq(E, ...) | platform_get_irq_byname(E, ...) ); if ( \( ret < 0 \| ret <= 0 \) ) { ( -if (ret != -EPROBE_DEFER) -{ ... -dev_err(...); -... } | ... -dev_err(...); ) ... } // </smpl> While we're here, remove braces on if statements that only have one statement (manually).

2019-07-24Input: fsl-imx25-tcq - use devm_platform_ioremap_resource()Mukesh Ojha
devm_platform_ioremap_resource() internally have platform_get_resource() and devm_ioremap_resource() in it. So instead of calling them separately use devm_platform_ioremap_resource() directly.

2016-10-26Input: fsl-imx25-tcq - fix module autoload when registered via OFJavier Martinez Canillas
If the driver is built as a module, autoload won't work because the module alias information is not filled. So user-space can't match the registered device with the corresponding module. Export the module alias information using the MODULE_DEVICE_TABLE() macro. Before this patch: $ modinfo drivers/input/touchscreen/fsl-imx25-tcq.ko | grep alias After this patch: $ modinfo drivers/input/touchscreen/fsl-imx25-tcq.ko | grep alias alias: of:N*T*Cfsl,imx25-tcqC* alias: of:N*T*Cfsl,imx25-tcq Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2016-02-11Input: touchscreen: Add imx25 TCQ driverMarkus Pargmann
This is a driver for the imx25 ADC/TSC module. It controls the touchscreen conversion queue and creates a touchscreen input device. The driver currently only supports 4 wire touchscreens. The driver uses a simple conversion queue of precharge, touch detection, X measurement, Y measurement, precharge and another touch detection. This driver uses the regmap from the parent to setup some touch specific settings in the core driver and setup a idle configuration with touch detection.
