Have there been any review comments? What are the current plans please?
If some of the patch aspects are controversial (for example, LED's), would it be possible to merge this series partially? For example, add basic support for buttons and keys, while leaving LEDs / rumble / etc in the review queue? Also, is it possible to combine some of these patches? For example, maybe patches 6, 7, 8 can be combined with patch 1? This would make it easier to merge into Android kernels.

I cc'd you on the latest v16 patchset. I think the main blocker right now is waiting for Roderick's LED definitions patch to be accepted: https://patchwork.kernel.org/project/linux-input/patch/20210908165539.3102929-3-roderick.colenbrander@sony.com/ - Daniel Ogorchock
I've updated the driver to use the "player" string introduced in Roderick's pending patch. I'll update the series again if that pending patch is altered or a different approach is decided on. Some stability improvements are included as well. Version 14 changes: - Use proper LED classdev name scheme - Prevent situations where a missed zero amplitude rumble packet would leave the controller stuck vibrating until a timeout - Introduce a max rate at which subcommands or rumble packets can be sent to the controller. This reduces bluetooth disconnects. - Send rumble packets immediately after receiving input reports. This reduces bluetooth disconnects (similar technique was already used for subcommands). Version 13 changes: - Switched to using the dedicated rumble data message type, rather than constantly resending the rumble enabled subcommand. This more closely resembles how the console itself handles rumble data. - Applied revisions based on Silvan Jegen's feedback on v12. Version 12 changes: - Added support for reading user calibration from the controller's SPI flash (written when someone calibrates the controller on the Nintendo switch). - Added patch to prevent sending rumble subcommands when no effect is being played. This turned out to drastically improve bluetooth connection reliability. - Set the battery description to POWER_SUPPLY_TYPE_BATTERY (was missing in previous revisions due to oversight). This fixes problems with desktop environments not handling the controller batteries properly. - Reintroduced IMU patch with improvements to documentation, packet drop handling, and increased precision for gyro readings. Also now blacklists the IMU input dev from joydev like hid-sony. Version 11 changes: - Removed IMU patch for now, since it has some issues to work out. - Fixed bug introduced in v10 which led to the joy-cons' S-triggers not being configured as an input. - Changed the pro controller's d-pad input from buttons to a hat to be more in line with other controller drivers. Version 10 changes: - Removed duplicate reporting of one of the triggers that Billy noticed - The joy-cons now only report having the buttons they actually have (they used to register the input devices with the buttons of the other joy-con as well). - The input device is now created after the LEDs/power supply. - The removed state handling bool has been removed, instead opting to add a new controller state (removed). - Eliminated a 1 second delay when probing a USB controller. - Added support for the IMU. This mostly consisted of merging in some work provided by Carl. I'm not incredibly familiar with proper gyro/accelerometer handling in linux, so this might need some tweaking. Preliminary tests in evtest show the gyro/accel values being reported. - Added support for the joy-con USB charging grip. Version 9 changes: - Fixed compiler errors on gcc versions older than 8.2 - Set input device's uniq value to the controller's MAC address Version 8 changes: - Corrected the handshaking protocol with USB pro controllers. A handshake now occurs both prior and after the baudrate set. This doesn't appear to have a noticeable difference, but it more accurately follows documentation found online. - Fixed potential race condition which could lead to a slightly longer delay sending subcommands in rare circumstances. - Moved the rumble worker to its own workqueue, since it can block. This prevents it from having a negative impact on the default kernel workqueue. It also prevents dropped subcommands due to something else blocking the kernel workqueue. The benefit is most obvious when using multiple controllers at once, since the controller subcommand timings are very picky. - Added a patch to set the most significant bit of the hid hw version. Roderick had mentioned needing to probably do this awhile ago, but I had forgotten about it until now. This is the same thing hid-sony does. It allows SDL2 to have different mappings for the hid-nintendo driver vs the default hid mappings. Version 7 changes: - Changed name to hid-nintendo to fit modern naming conventions - Removed joycon_ctlr_destroy(), since it wasn't needed an could potentially invalidate a mutex while it could be in use on other threads - Implemented minor code improvements suggested by Silvan - The driver now waits to send subcommands until after receiving an input report. This significantly reduces dropped subcommands. - Reduced the number of error messages when disconnecting a controller. Version 6 changes: - Improved subcommand sending reliabilty - Decreased rumble period to 50ms - Added rumble queue to avoid missing ff_effects if sent too quickly - Code cleanup and minor refactoring - Added default analog stick calibration Version 5 changes: - Removed sysfs interface to control motor frequencies. - Improved rumble reliability by using subcommands to set it. - Changed mapping of the SL/SR triggers on the joy-cons to map to whichever triggers they lack (e.g. a left joycon's sl/sr map to TR and TR2). This allows userspace to distinguish between the normal and S triggers. - Minor refactors Version 4 changes: - Added support for the Home button LED for the pro controller and right joy-con - Changed name from hid-switchcon to hid-joycon - Added rumble support - Removed ctlr->type and use hdev->product instead - Use POWER_SUPPLY_CAPACITY_LEVEL enum instead of manually translating to capacity percentages - Misc. minor refactors based on v3 feedback Version 3 changes: - Added led_classdev support for the 4 player LEDs - Added power_supply support for the controller's battery - Made the controller number mutex static - Minor refactoring/style fixes based on Roderick's feedback from v2 Version 2 changes: - Switched to using a synchronous method for configuring the controller. - Removed any pairing/orientation logic in the driver. Every controller now corresponds to its own input device. - Store controller button data as a single u32. - Style corrections Daniel J.
