HID: wacom: insert timestamp to packed Bluetooth (BT) events

2023-05-17T12:02:03+00:00

commit 17d793f3ed53080dab6bbeabfc82de890c901001 upstream.

To fully utilize the BT polling/refresh rate, a few input events
are sent together to reduce event delay. This causes issue to the
timestamp generated by input_sync since all the events in the same
packet would pretty much have the same timestamp. This patch inserts
time interval to the events by averaging the total time used for
sending the packet.

This decision was mainly based on observing the actual time interval
between each BT polling. The interval doesn't seem to be constant,
due to the network and system environment. So, using solutions other
than averaging doesn't end up with valid timestamps.

HID: wacom: Set a default resolution for older tablets

2023-05-17T12:02:03+00:00

commit 08a46b4190d345544d04ce4fe2e1844b772b8535 upstream.

Some older tablets may not report physical maximum for X/Y
coordinates. Set a default to prevent undefined resolution.

HID: amd_sfh: Handle "no sensors" enabled for SFH1.1

2023-05-11T14:17:26+00:00

[ Upstream commit 8455cbb25927013b3417ab619dced1c0e87708af ]

Based on num_hid_devices, each sensor device is initialized. If
"no sensors" is initialized, amd_sfh work initialization and scheduling
doesn’t make sense and returns EOPNOTSUPP to stop driver probe. Hence,
add a check for "no sensors" enabled to handle the special case.

HID: amd_sfh: Increase sensor command timeout for SFH1.1

2023-05-11T14:17:26+00:00

[ Upstream commit 571dc8f59dd477037bb5a029e8d1b5a4a4d9dd63 ]

The initialization of SFH1.1 sensors may take some time. Hence, increase
sensor command timeouts in order to obtain status responses within a
maximum timeout.

HID: amd_sfh: Correct the stop all command

[ Upstream commit 82c2a0d137794f5ef47982231593a00aee26ce3b ]

Misinterpreted the stop all command in SHF1.1 firmware. Therefore, it is
necessary to update the stop all command accordingly to disable all
sensors.

HID: amd_sfh: Add support for shutdown operation

2023-05-11T14:17:26+00:00

[ Upstream commit 1353ecaf1830d6d1b74f3225378a9498b4e14fdd ]

As soon as the system is booted after shutdown, the sensors may remain in
a weird state and fail to initialize. Therefore, all sensors should be
turned off during shutdown.

[ Upstream commit a33e5e393171ae8384d3381db5cd159ba877cfcb ]

Illuminance value is actually 32 bits, but is incorrectly trancated to
16 bits. Hence convert to integer illuminace accordingly to reflect
correct values.

[ Upstream commit 0b9255bf11baa61cd526e6bd24d6c8e6d1eabf8d ]

In order to start or stop sensors, the firmware command needs to be
changed to add an additional default subcommand value. For this reason,
add a subcommand value to enable or disable sensors accordingly.
