HID: i2c-hid: Revert to using power commands to wake on resume

2024-11-28T10:18:14Z

commit 7d6f065de37c ("HID: i2c-hid: Use address probe to wake on resume") replaced the retry of power commands with the dummy read "bus probe" we use on boot which accounts for a necessary delay before retry. This made at least one Weida device (2575:0910 in an ASUS Vivobook S14) very unhappy, as the bus probe despite being successful somehow lead to the following power command failing so hard that the device never lets go of the bus. This means that even retries of the power command would fail on a timeout as the bus remains busy. Remove the bus probe on resume and instead reintroduce retry of the power command for wake-up purposes while respecting the newly established wake-up retry timings.

HID: i2c-hid: Delayed i2c resume wakeup for 0x0d42 Goodix touchpad

2024-10-18T10:32:06Z

Patch for Goodix 27c6:0d42 touchpads found in Inspiron 5515 laptops. After resume from suspend, one can communicate with this device just fine. We can read data from it or request a reset, but for some reason the interrupt line will not go up when new events are available. (it can correctly respond to a reset with an interrupt tho) The only way I found to wake this device up is to send anything to it after ~1.5s mark, for example a simple read request, or power mode change. In this patch, I simply delay the resume steps with msleep, this will cause the set_power request to happen after the ~1.5s barrier causing the device to resume its event interrupts. Sleep was used rather than delayed_work to make this workaround as non-invasive as possible. [jkosina@suse.com: shortlog update] Signed-off-by: Bartłomiej Maryńczak Signed-off-by: Jiri Kosina

HID: i2c-hid-of: Drop explicit initialization of struct i2c_device_id::driver_data to 0

2024-10-08T06:51:10Z

These drivers don't use the driver_data member of struct i2c_device_id, so don't explicitly initialize this member. This prepares putting driver_data in an anonymous union which requires either no initialization or named designators. But it's also a nice cleanup on its own. While touching the initializer, also remove the comma after the sentinel entry. Signed-off-by: Uwe Kleine-König Reviewed-by: Douglas Anderson Signed-off-by: Jiri Kosina

move asm/unaligned.h to linux/unaligned.h

asm/unaligned.h is always an include of asm-generic/unaligned.h; might as well move that thing to linux/unaligned.h and include that - there's nothing arch-specific in that header. auto-generated by the following: for i in `git grep -l -w asm/unaligned.h`; do sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i done for i in `git grep -l -w asm-generic/unaligned.h`; do sed -i -e "s/asm-generic\/unaligned.h/linux\/unaligned.h/" $i done git mv include/asm-generic/unaligned.h include/linux/unaligned.h git mv tools/include/asm-generic/unaligned.h tools/include/linux/unaligned.h sed -i -e "/unaligned.h/d" include/asm-generic/Kbuild sed -i -e "s/__ASM_GENERIC/__LINUX/" include/linux/unaligned.h tools/include/linux/unaligned.h

HID: i2c-hid: ensure various commands do not interfere with each other

2024-09-12T12:11:36Z

i2c-hid uses 2 shared buffers: command and "raw" input buffer for sending requests to peripherals and read data from peripherals when executing variety of commands. Such commands include reading of HID registers, requesting particular power mode, getting and setting reports and so on. Because all such requests use the same 2 buffers they should not execute simultaneously. Fix this by introducing "cmd_lock" mutex and acquire it whenever we needs to access ihid->cmdbuf or idid->rawbuf. Signed-off-by: Dmitry Torokhov Reviewed-by: Hans de Goede Signed-off-by: Jiri Kosina

HID: i2c-hid: elan: Add elan-ekth6a12nay timing

2024-09-03T11:21:21Z

Elan-ekth6a12nay requires reset to pull down time greater than 10ms, so the configuration post_power_delay_ms is 10, and the chipset initial time is required to be greater than 300ms, so the post_gpio_reset_on_delay_ms is set to 300.

HID: i2c-hid: elan: fix reset suspend current leakage

2024-06-07T09:18:11Z

The Elan eKTH5015M touch controller found on the Lenovo ThinkPad X13s shares the VCC33 supply with other peripherals that may remain powered during suspend (e.g. when enabled as wakeup sources). The reset line is also wired so that it can be left deasserted when the supply is off. This is important as it avoids holding the controller in reset for extended periods of time when it remains powered, which can lead to increased power consumption, and also avoids leaking current through the X13s reset circuitry during suspend (and after driver unbind). Use the new 'no-reset-on-power-off' devicetree property to determine when reset needs to be asserted on power down. Notably this also avoids wasting power on machine variants without a touchscreen for which the driver would otherwise exit probe with reset asserted.
