bd3cba00 - HID: i2c-hid: elan: Add support for Elan eKTH6915 i2c-hid touchscreens

Mon, 23 May 2022 21:23:24 +0000

HID: i2c-hid: elan: Add support for Elan eKTH6915 i2c-hid touchscreensLike many i2c-hid touchscreen controllers, the Elan eKTH6915 has areset GPIO hooked up to it. According to the datasheet, the way we'resupposed to turn the touchscreen on is:1. Turn on the 3.3V supply.2. Turn on the IO supply. It's OK if this is hardwired to the 3.3V supply, but if it's not then it must be turned on _after_ the 3.3V supply.3. Wait >= 1 ms.4. Deassert the reset GPIO (reset GPIO is active low, so there would be a leakage path if this was deasserted _before_ the IO supply).5. Wait 300 ms.Much of the above can be handled by the generic i2c-hid-of driver, butthe "reset" GPIO is not supported by that driver. Thus we'll do thesame as we did for Goodix and add a new tiny driver that uses thei2c-hid core.NOTE: support for this new touchscreen could theorically fit into theGoodix driver. I've made it a separate driver because the Elan driversupports _two_ regulators and it's unclear exactly how that would fitin with commit 18eeef46d359 ("HID: i2c-hid: goodix: Tie the reset lineto true state of the regulator").Signed-off-by: Douglas Anderson Reviewed-by: Dmitry Torokhov Reviewed-by: Matthias Kaehlcke Signed-off-by: Jiri Kosina List of files: /linux-6.15/drivers/hid/i2c-hid/Makefile

HID: i2c-hid: Introduce goodix-i2c-hid using i2c-hid coreGoodix i2c-hid touchscreens are mostly i2c-hid compliant but have somespecial power sequencing requirements, including the need to drive areset line during the sequencing.Let's use the new rejiggering of i2c-hid to support this with a thinwrapper driver to support the first Goodix i2c-hid touchscreen:GT7375PSigned-off-by: Douglas Anderson Signed-off-by: Benjamin Tissoires List of files: /linux-6.15/drivers/hid/i2c-hid/Makefile

b33752c3 - HID: i2c-hid: Reorganize so ACPI and OF are separate modules

Fri, 15 Jan 2021 17:06:37 +0000

HID: i2c-hid: Reorganize so ACPI and OF are separate modulesThis patch rejiggers the i2c-hid code so that the OF (Open Firmwareaka Device Tree) and ACPI support is separated out a bit. The OF andACPI drivers are now separate modules that wrap the core module.Essentially, what we're doing here:* Make "power up" and "power down" a function that can be (optionally) implemented by a given user of the i2c-hid core.* The OF and ACPI modules are drivers on their own, so they implement probe / remove / suspend / resume / shutdown. The core code provides implementations that OF and ACPI can call into.We'll organize this so that we now have 3 modules: the old i2c-hidmodule becomes the "core" module and two new modules will depend onit, handling probing the specific device.As part of this work, we'll remove the i2c-hid "platform data"concept since it's not needed.Signed-off-by: Douglas Anderson Reviewed-by: Hans de Goede Signed-off-by: Benjamin Tissoires List of files: /linux-6.15/drivers/hid/i2c-hid/Makefile

9ee3e066 - HID: i2c-hid: override HID descriptors for certain devices

Wed, 19 Sep 2018 09:46:23 +0000

HID: i2c-hid: override HID descriptors for certain devicesA particular touchpad (SIPODEV SP1064) refuses to supply the HIDdescriptors. This patch provides the framework for overriding thesedescriptors based on DMI data. It also includes the descriptors forsaid touchpad, which were extracted by listening to the traffic of thewindows filter driver, as well as the DMI data for the laptops knownto use this device.Relevant Bug: https://bugzilla.redhat.com/show_bug.cgi?id=1526312Cc: Hans de Goede Reported-and-tested-by: ahormann@gmx.netReported-and-tested-by: Bruno Jesus Reported-and-tested-by: Dietrich Reported-and-tested-by: kloxdami@yahoo.comSigned-off-by: Julian Sax Reviewed-by: Benjamin Tissoires Signed-off-by: Jiri Kosina List of files: /linux-6.15/drivers/hid/i2c-hid/Makefile

4a200c3b - HID: i2c-hid: introduce HID over i2c specification implementation

Mon, 12 Nov 2012 14:42:59 +0000

HID: i2c-hid: introduce HID over i2c specification implementationMicrosoft published the protocol specification of HID over i2c:http://msdn.microsoft.com/en-us/library/windows/hardware/hh852380.aspxThis patch introduces an implementation of this protocol.This implementation does not includes the ACPI part of the specification.This will come when ACPI 5.0 devices enumeration will be available.Once the ACPI part is done, OEM will not have to declare HID over I2Cdevices in their platform specific driver.Signed-off-by: Benjamin Tissoires Signed-off-by: Jiri Kosina List of files: /linux-6.15/drivers/hid/i2c-hid/Makefile
