Input: eeti_ts - read hardware state once after wakeup

2019-05-15T23:29:14+00:00

For systems in which the touch IRQ is acting as wakeup source, and that do not support level-driven interrupts, the interrupt controller might not latch the GPIO IRQ during sleep. In such cases, the interrupt will never occur again after resume, hence the touch screen appears dead. To fix this, check for the assertion of the attn gpio, and read form the controller once in the resume path to read the hardware status and to arm the IRQ again. Introduce a mutex to guard eeti_ts_read() against parallel invocations from different contexts. Signed-off-by: Daniel Mack Reported-by: Sven Neumann Signed-off-by: Dmitry Torokhov

Input: eeti - fix link to documentation and email address in header

2018-07-04T16:08:05+00:00

Keep the documentation link up-to-date in case anybody need to dive into it again, and update email address while at it. Signed-off-by: Daniel Mack Signed-off-by: Dmitry Torokhov

Input: eeti - drop module parameters, parse DT properties

2018-07-04T16:08:01+00:00

The only user of this driver in mainline does not make use of the module parameters, so let's remove them. All properties for this driver should be set through DT or pdata. Use touchscreen_parse_properties() to automatically set some of the common touchscreen properties and derive the axis inversion through that. And finally, use touchscreen_report_pos() to handle the DT properties automatically instead of doing the inversion ourselves. Signed-off-by: Daniel Mack Signed-off-by: Dmitry Torokhov

Input: eeti - add device tree matching table

2018-07-04T16:07:56+00:00

Provide a match table so that the driver can be used in devicetree setups. More properties are added in a later patch. Signed-off-by: Daniel Mack Signed-off-by: Dmitry Torokhov

Input: eeti_ts - switch to gpiod API

2017-04-05T15:52:33+00:00

gpiod API allows standard way of specifying GPIO polarity and takes it into account when reading or setting GPIO state. It also allows us to switch to common way of obtaining GPIO descriptor and away form legacy platform data. Reviewed-by: Daniel Mack Signed-off-by: Dmitry Torokhov

Input: eeti_ts - expect platform code to set interrupt trigger

2017-04-05T15:52:13+00:00

Instead of keying interrupt trigger off GPIO polarity, let's rely on platform code to set it up properly for us. Reviewed-by: Daniel Mack Signed-off-by: Dmitry Torokhov

Input: eeti_ts - switch to using threaded interrupt

2017-04-03T23:24:34+00:00

Instead of having standard interrupt handler and manually firing work item to perform I2C reads, let's switch to threaded interrupts, which were designed specifically for this purpose. Reviewed-by: Daniel Mack Signed-off-by: Dmitry Torokhov

Input: eeti_ts - use gpio_get_value_cansleep

2017-04-03T23:24:33+00:00

We are reading GPIO state in a non-atomic context (workqueue), so we can use "cansleep" variant, and thus make the driver available on systems where GPIO controllers require sleeping when reading GPIO state. Reviewed-by: Daniel Mack Signed-off-by: Dmitry Torokhov
