Input: eeti_ts - switch to gpiod API

2017-04-05T15:52:33Z

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

2017-04-05T15:52:13Z

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

2017-04-03T23:24:34Z

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

2017-04-03T23:24:33Z

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

Input: eeti_ts - respect interrupt set in client structure

2017-04-03T23:24:33Z

Instead of expecting that GPIO is always interrupt source, let's use interrupt specified in I2C client. Reviewed-by: Daniel Mack Signed-off-by: Dmitry Torokhov

Input: eeti_ts - switch to using managed resources

2017-04-03T23:24:32Z

Using devm_* APIs simpifies error handling and device teardown. Reviewed-by: Daniel Mack Signed-off-by: Dmitry Torokhov

Input: eeti_ts - use input_set_capability()

2017-04-03T23:24:32Z

Use input_set_capability() instead of manipulating evbit/keybit masks directly. Reviewed-by: Daniel Mack Signed-off-by: Dmitry Torokhov

Input: eeti_ts - use get_unaligned_be16() to retrieve data

2017-04-03T23:24:31Z

Instead of manually converting big endian data on wire into host endianness, let's use helpers to do that for us. It might save us a few cycles if host endianness matches what's on wire. Reviewed-by: Daniel Mack Signed-off-by: Dmitry Torokhov

Input: eeti_ts - use BIT(n)

2017-04-03T23:24:30Z

Use idiomatic BIT(n) to form single-bit masks. Reviewed-by: Daniel Mack Signed-off-by: Dmitry Torokhov

Input: eeti_ts - rename eeti_ts_priv to eeti_ts

2017-04-03T23:24:30Z

Also rename 'priv' variables to eeti. Reviewed-by: Daniel Mack Signed-off-by: Dmitry Torokhov
