HID: sony: remove redundant check for -ve err

2017-04-06T12:47:17+00:00

err is being checked for failure each time it is being updated so this err check is totally redundant and can be removed Detected with CoverityScan, CID#1420665 ("Logically dead code") Signed-off-by: Colin Ian King Reviewed-by: Benjamin Tissoires Signed-off-by: Jiri Kosina

HID: sony: Make sure to unregister sensors on failure

2017-04-06T12:42:56+00:00

Make sure we sure register any sensor when sony_input_configured failes. Somehow this line got lost during resolving of merge conflicts in the motion sensor patch series and a redudant remove was added as well later on. Signed-off-by: Roderick Colenbrander Signed-off-by: Jiri Kosina

HID: sony: Make DS4 bt poll interval adjustable

2017-04-06T12:41:17+00:00

By default when using bluetooth the DS4 reports data at about 1kHz, which is quite fast especially on weak devices. We now make the device use the USB poll interval, which is a fixed 4ms. In addition we make the value adjustable through sysfs. The error handling in sony_input_configured is a little tricky. It is not easy to add other goto's as not all codepaths have logic for adding this attribute. Luckily we are setting the value for the attribute to a default value, so we can use that to detect if we need to remove the file. Signed-off-by: Roderick Colenbrander Signed-off-by: Jiri Kosina

HID: sony: Set proper bit flags on DS4 output report

2017-04-06T12:41:17+00:00

Only set bit flags for the portions of the DS4 output report for which we have data. Signed-off-by: Roderick Colenbrander Signed-off-by: Jiri Kosina

HID: sony: DS4 use brighter LED colors

2017-04-06T12:41:17+00:00

These colors are more the default colors normally used on the DS4. The previous ones were faint and not so noticeable. Signed-off-by: Roderick Colenbrander Signed-off-by: Jiri Kosina

HID: sony: Improve navigation controller axis/button mapping

2017-04-06T12:41:16+00:00

The navigation controller is a DS3 (sixaxis) with fewer physical axes and buttons. It utilizes the same HID report as the DS3 and thus reports axes/buttons which aren't physically present. Currently many non-existing buttons and axes are reported, which we are now removing. For the axes/buttons which do exist, we make the axis/button mapping similar to the DS3.

HID: sony: Use DS3 MAC address as unique identifier on USB

2017-04-06T12:41:16+00:00

The DS3 MAC address is reported as a unique identified when using Bluetooth. For USB there is no unique identifier reported yet, so use the MAC address. Signed-off-by: Roderick Colenbrander Signed-off-by: Jiri Kosina

HID: sony: Perform duplicate device check earlier on

2017-03-21T14:12:07+00:00

Game controllers can be connected twice through USB and BT. Only one connection is allowed. Currently we perform a check for duplicate controllers halfway through device initialization. To prevent 'transient' devices, we should do this check as early as we can. Signed-off-by: Roderick Colenbrander Signed-off-by: Jiri Kosina

HID: sony: Expose DS3 motion sensors through separate device

2017-03-21T14:12:07+00:00

This patch adds a separate evdev node for the DS3 its motion sensors. We only expose the accelerometers as the gyroscope is extremely difficult to manage and behavior varies a lot between hardware revisions. Signed-off-by: Roderick Colenbrander Signed-off-by: Jiri Kosina
