2023-06-06Input: tps65219-pwrbutton - convert to .remove_new()Uwe Kleine-König1-5/+8
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning). To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Eventually after all drivers are converted, .remove_new() is renamed to .remove(). Before this driver might have returned an error. In this case emit a warning that tells more about the problem than the generic warning by the core, and instead of making the remove callback return zero unconditionally, convert to .remove_new() which is equivalent.

2023-05-24Input: ads7846 - Convert to use software nodesLinus Walleij1-72/+41
The Nokia 770 is using GPIOs from the global numberspace on the CBUS node to pass down to the LCD controller. This regresses when we let the OMAP GPIO driver use dynamic GPIO base. The Nokia 770 now has dynamic allocation of IRQ numbers, so this needs to be fixed for it to work. As this is the only user of LCD MIPID we can easily augment the driver to use a GPIO descriptor instead and resolve the issue. The platform data .shutdown() callback wasn't even used in the code, but we encode a shutdown asserting RESET in the remove() callback for completeness sake. The CBUS also has the ADS7846 touchscreen attached. Populate the devices on the Nokia 770 CBUS I2C using software nodes instead of platform data quirks. This includes the LCD and the ADS7846 touchscreen so the conversion just brings the LCD along with it as software nodes is an all-or-nothing design pattern. The ADS7846 has some limited support for using GPIO descriptors, let's convert it over completely to using device properties and then fix all remaining boardfile users to provide all platform data using software nodes. Dump the of includes and of_match_ptr() in the ADS7846 driver as part of the job. Since we have to move ADS7846 over to obtaining the GPIOs it is using exclusively from descriptors, we provide descriptor tables for the two remaining in-kernel boardfiles using ADS7846: - PXA Spitz - MIPS Alchemy DB1000 development board It was too hard for me to include software node conversion of these two remaining users at this time: the spitz is using a hscync callback in the platform data that would require further GPIO descriptor conversion of the Spitz, and moving the hsync callback down into the driver: it will just become too big of a job, but it can be done separately. The MIPS Alchemy DB1000 is simply something I cannot test, so take the easier approach of just providing some GPIO descriptors in this case as I don't want the patch to grow too intrusive. As we see that several device trees have incorrect polarity flags and just expect to bypass the gpiolib polarity handling, fix up all device trees too, in a separate patch.

While doing my research to improve the xpad device names I noticed that the 1532:0037 VID/PID seems to be used by the DeathAdder 2013, so that Razer Sabertooth instance looked wrong and very suspect to me. I didn't see any mention in the official drivers, either. After doing more research, it turns out that the xpad list is used by many other projects (like Steam) as-is [1], this issue was reported [2] and Valve/Sam Lantinga fixed it [3]: [1]: https://github.com/libsdl-org/SDL/blob/dcc5eef0e2395854b254ea2873a4899edab347c6/src/joystick/controller_type.h#L251 [2]: https://steamcommunity.com/app/353380/discussions/0/1743392486228754770/ [3]: https://hg.libsdl.org/SDL/rev/29809f6f0271 (With multiple Internet users reporting similar issues, not linked here) After not being able to find the correct VID/PID combination anywhere on the Internet and not receiving any reply from Razer support I did some additional detective work, it seems like it presents itself as "Razer Sabertooth Gaming Controller (XBOX360)", code 1689:FE00. Leaving us with this: * Razer Sabertooth (1689:fe00) * Razer Sabertooth Elite (24c6:5d04) * Razer DeathAdder 2013 (1532:0037) [note: not a gamepad] So, to sum things up; remove this conflicting/duplicate entry: { 0x1532, 0x0037, "Razer Sabertooth", 0, XTYPE_XBOX360 }, As the real/correct one is already present there, even if the Internet as a whole insists on presenting it as the Razer Sabertooth Elite, which (by all accounts) is not: { 0x1689, 0xfe00, "Razer Sabertooth", 0, XTYPE_XBOX360 }, Actual change in SDL2 referencing this kernel issue: https://github.com/libsdl-org/SDL/commit/e5e54169754ca5d3e86339d968b20126d9da0a15 For more information of the device, take a look here: https://github.com/xboxdrv/xboxdrv/pull/59 You can see a lsusb dump here: https://github.com/xboxdrv/xboxdrv/files/76581/Qa6dBcrv.txt Fixes: f554f619b70 ("Input: xpad - sync device IDs with xboxdrv") Signed-off-by: Ismael Ferreras Morezuelas <swyterzone@gmail.com> Reviewed-by: Cameron Gutman <aicommander@gmail.com> Cc: stable@vger.kernel.org Link: https://lore.kernel.org/r/5c12dbdb-5774-fc68-5c58-ca596383663e@gmail.com Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

2023-05-18Input: libps2 - do not discard non-ack bytes when controlling LEDsDmitry Torokhov1-4/+32
Upon receiving a PS/2 command the device and controller are supposed to stop sending normal data (scancodes or movement packets) and instead immediately start delivering ACK/NAK and command response. Unfortunately often EC has an output buffer which may contain latched data by the time the EC receives a command from the host. The kernel used to ignore such data, but that may cause "stuck" keys if the data dropped happens to be a break code or a part of a break code. This occasionally happens, for example, on Chromebooks when the kernel tries to toggle CapsLock LED on a keyboard while user releases Alt+Search keyboard shortcut. Fix this by passing the first non-ACK byte to the normal handler for a handful of PS/2 commands that are expected to be used during normal device operation (as opposed to probe/configuration time).

2023-05-02Input: drv260x - fix magnitude handlingLuca Weiss1-6/+7
First of all, previously the 16-bit magnitude was written as-is to the device which actually discarded the upper 8 bits since the device has 8-bit registers only. This meant that a strong_magnitude of 0xFF00 would result in 0. To correct this shift the strong_magnitude / weak_magnitude input values so we discard the lower 8 bits and keep the upper bits instead. Secondly the RTP mode that is used by default interprets the values as signed (2s complement), so 0x81 = 0%, 0x00 = 50%, 0x7F = 100%. This doesn't match the FF_RUMBLE interface at all, so let's tell the device to interpret the data as unsigned instead which gets us 0x00 = 0% and 0xFF = 100%. As last change switch ERM to using "Closed-Loop Mode, Unidirectional" instead of "Open-Loop Mode" since it's recommended by the datasheet compared to open loop and better matches our use case of 0% - 100% vibration.
