Input: ads7846 - correct the value got from SPI

2015-10-06T23:39:14+00:00

According to the touch controller spec, SPI return a 16 bit value, only 12 bits are valid, they are bit[14-3]. The value of MISO and MOSI can be configured when SPI is in idle mode. Currently this touch driver assumes the SPI bus sets the MOSI and MISO in low level when SPI bus is in idle mode. So the bit[15] of the value got from SPI bus is always 0. But when SPI bus congfigures the MOSI and MISO in high level during the SPI idle mode, the bit[15] of the value get from SPI is always 1. If bit[15] is not masked, we may get the wrong value. Mask the invalid bit to make sure the correct value gets returned. Regardless of the SPI bus idle configuration.

Input: ads7846 - change name of wakeup property to "wakeup-source"

2015-07-23T22:01:22+00:00

Wakeup property of device is not Linux-specific, it describes intended system behavior regardless of the OS being used. Therefore let's drop "linux," prefix, and, while at it, use the same name as I2C bus does: "wakeup-source". We keep parsing old name to keep compatibility with old DTSes.

Input: touchscreen - use __maybe_unused instead of ifdef around suspend/resume

2014-11-02T07:10:07+00:00

Use __maybe_unused instead of ifdef guards around suspend/resume functions, in order to increase build coverage and fix build warnings. Signed-off-by: Jingoo Han Signed-off-by: Dmitry Torokhov

Input: ads7846 - release resources on failure for clean exit

2014-07-31T05:52:09+00:00

Input device must be released(input_free_device) when ads7846_probe_dt fails. This fixes the same by releasing resources on failure. Signed-off-by: Pramod Gurav Signed-off-by: Dmitry Torokhov

Merge tag 'v3.15-rc5' into next

Merge with Linux 3.15-rc5 to sync up Wacom and other changes.

Input: ads7846 - correct log message for spi_sync() errors

2014-05-14T23:39:45+00:00

While searching for users of spi_async() I got a false positive in the ads7846 driver, fix that. Signed-off-by: Mark Brown Signed-off-by: Dmitry Torokhov

Input: ads7846 - fix device usage within attribute show

2014-04-19T20:55:59+00:00

With commit e585c40ba (Input: ads7846 - convert to hwmon_device_register_with_groups()) the device passed to the attribute's show function isn't the spi device as before. So fixup the passed device to ads7846_read12_ser. Signed-off-by: Alexander Stein Acked-by: Guenter Roeck Signed-off-by: Dmitry Torokhov

Input: delete non-required instances of include

2014-01-07T07:23:57+00:00

None of these files are actually using any __init type directives and hence don't need to include . Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next. Signed-off-by: Paul Gortmaker Signed-off-by: Dmitry Torokhov

Input: ads7846 - convert to hwmon_device_register_with_groups()

2013-12-16T10:13:26+00:00

Simplify the code and create mandatory 'name' attribute by using new hwmon API. Also use is_visible to determine visible attributes instead of creating several different attribute groups. Signed-off-by: Guenter Roeck Signed-off-by: Dmitry Torokhov

Input: ads7846 - use IS_ENABLED() macro
