Input: ads7846 - don't check penirq immediately for 7845

2023-03-11T15:43:51+00:00

[ Upstream commit fa9f4275b20ec7b2a8fb05c66362d10b36f9efec ] To discard false readings, one should use "ti,penirq-recheck-delay-usecs". Checking get_pendown_state() at the beginning, most of the time fails causing malfunctioning.

treewide: Replace DECLARE_TASKLET() with DECLARE_TASKLET_OLD()

2023-03-11T15:43:42+00:00

[ Upstream commit b13fecb1c3a603c4b8e99b306fecf4f668c11b32 ] This converts all the existing DECLARE_TASKLET() (and ...DISABLED) macros with DECLARE_TASKLET_OLD() in preparation for refactoring the tasklet callback type. All existing DECLARE_TASKLET() users had a "0" data argument, it has been removed here as well.

Input: i8042 - add TUXEDO devices to i8042 quirk tables

2023-02-22T11:50:27+00:00

[ Upstream commit a6a87c36165e6791eeaed88025cde270536c3198 ] A lot of modern Clevo barebones have touchpad and/or keyboard issues after suspend fixable with nomux + reset + noloop + nopnp. Luckily, none of them have an external PS/2 port so this can safely be set for all of them. I'm not entirely sure if every device listed really needs all four quirks, but after testing and production use. No negative effects could be observed when setting all four. The list is quite massive as neither the TUXEDO nor the Clevo dmi strings have been very consistent historically. I tried to keep the list as short as possible without risking on missing an affected device. This is revision 3. The Clevo N150CU barebone is still removed as it might have problems with the fix and needs further investigations. The SchenkerTechnologiesGmbH System-/Board-Vendor string variations are added. This is now based in the quirk table refactor. This now also includes the additional noaux flag for the NS7xMU.

Input: i8042 - merge quirk tables

2023-02-22T11:50:26+00:00

[ Upstream commit ff946268a0813c35b790dfbe07c3bfaa7bfb869c ] Merge i8042 quirk tables to reduce code duplication for devices that need more than one quirk. Before every quirk had its own table with devices needing that quirk. If a new quirk needed to be added a new table had to be created. When a device needed multiple quirks, it appeared in multiple tables. Now only one table called i8042_dmi_quirk_table exists. In it every device has one entry and required quirks are coded in the .driver_data field of the struct dmi_system_id used by this table. Multiple quirks for one device can be applied by bitwise-or of the new SERIO_QUIRK_* defines. Also align quirkable options with command line parameters and make vendor wide quirks per device overwriteable on a per device basis. The first match is honored while following matches are ignored. So when a vendor wide quirk is defined in the table, a device can inserted before and therefore ignoring the vendor wide define.

Input: elants_i2c - properly handle the reset GPIO when power is off

2023-01-18T10:41:03+00:00

[ Upstream commit a85fbd6498441694475716a4d5c65f9d3e073faf ] As can be seen in elants_i2c_power_off(), we want the reset GPIO asserted when power is off. The reset GPIO is active low so we need the reset line logic low when power is off to avoid leakage. We have a problem, though, at probe time. At probe time we haven't powered the regulators on yet but we have: devm_gpiod_get(&client->dev, "reset", GPIOD_OUT_LOW); While that _looks_ right, it turns out that it's not. The GPIOD_OUT_LOW doesn't mean to init the GPIO to low. It means init the GPIO to "not asserted". Since this is an active low GPIO that inits it to be high. Let's fix this to properly init the GPIO. Now after both probe and power off the state of the GPIO is consistent (it's "asserted" or level low). Once we fix this, we can see that at power on time we no longer to assert the reset GPIO as the first thing. The reset GPIO is _always_ asserted before powering on. Let's fix powering on to account for this.
