2022-05-31Input: mtk-pmic-keys - move long press debounce mask to mtk_pmic_regsAngeloGioacchino Del Regno
As the second and last step of preparation to add support for more PMICs in this driver, move the long press debounce mask to struct mtk_pmic_regs and use that in mtk_pmic_keys_lp_reset_setup() instead of directly using the definition. While at it, remove the definition for MTK_PMIC_RST_DU_SHIFT as we are able to calculate it dynamically and spares us some unnecessary new definitions around for future per-PMIC variations of RST_DU_MASK. Lastly, it was necessary to change the function signature of mtk_pmic_keys_lp_reset_setup() to now pass a pointer to the main mtk_pmic_regs structure, since that's where the reset debounce mask now resides. This commit brings no functional changes.

gpio_keys module can either accept gpios or interrupts. The module initializes delayed work in case of gpios only and is only used if debounce timer is not used, so make sure cancel_delayed_work_sync() is called only when its gpio-backed and debounce_use_hrtimer is false. This fixes the issue seen below when the gpio_keys module is unloaded and an interrupt pin is used instead of GPIO: [ 360.297569] ------------[ cut here ]------------ [ 360.302303] WARNING: CPU: 0 PID: 237 at kernel/workqueue.c:3066 __flush_work+0x414/0x470 [ 360.310531] Modules linked in: gpio_keys(-) [ 360.314797] CPU: 0 PID: 237 Comm: rmmod Not tainted 5.18.0-rc5-arm64-renesas-00116-g73636105874d-dirty #166 [ 360.324662] Hardware name: Renesas SMARC EVK based on r9a07g054l2 (DT) [ 360.331270] pstate: 60400005 (nZCv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--) [ 360.338318] pc : __flush_work+0x414/0x470 [ 360.342385] lr : __cancel_work_timer+0x140/0x1b0 [ 360.347065] sp : ffff80000a7fba00 [ 360.350423] x29: ffff80000a7fba00 x28: ffff000012b9c5c0 x27: 0000000000000000 [ 360.357664] x26: ffff80000a7fbb80 x25: ffff80000954d0a8 x24: 0000000000000001 [ 360.364904] x23: ffff800009757000 x22: 0000000000000000 x21: ffff80000919b000 [ 360.372143] x20: ffff00000f5974e0 x19: ffff00000f5974e0 x18: ffff8000097fcf48 [ 360.379382] x17: 0000000000000000 x16: 0000000000000000 x15: 0000000000053f40 [ 360.386622] x14: ffff800009850e88 x13: 0000000000000002 x12: 000000000000a60c [ 360.393861] x11: 000000000000a610 x10: 0000000000000000 x9 : 0000000000000008 [ 360.401100] x8 : 0101010101010101 x7 : 00000000a473c394 x6 : 0080808080808080 [ 360.408339] x5 : 0000000000000001 x4 : 0000000000000000 x3 : ffff80000919b458 [ 360.415578] x2 : ffff8000097577f0 x1 : 0000000000000001 x0 : 0000000000000000 [ 360.422818] Call trace: [ 360.425299] __flush_work+0x414/0x470 [ 360.429012] __cancel_work_timer+0x140/0x1b0 [ 360.433340] cancel_delayed_work_sync+0x10/0x18 [ 360.437931] gpio_keys_quiesce_key+0x28/0x58 [gpio_keys] [ 360.443327] devm_action_release+0x10/0x18 [ 360.447481] release_nodes+0x8c/0x1a0 [ 360.451194] devres_release_all+0x90/0x100 [ 360.455346] device_unbind_cleanup+0x14/0x60 [ 360.459677] device_release_driver_internal+0xe8/0x168 [ 360.464883] driver_detach+0x4c/0x90 [ 360.468509] bus_remove_driver+0x54/0xb0 [ 360.472485] driver_unregister+0x2c/0x58 [ 360.476462] platform_driver_unregister+0x10/0x18 [ 360.481230] gpio_keys_exit+0x14/0x828 [gpio_keys] [ 360.486088] __arm64_sys_delete_module+0x1e0/0x270 [ 360.490945] invoke_syscall+0x40/0xf8 [ 360.494661] el0_svc_common.constprop.3+0xf0/0x110 [ 360.499515] do_el0_svc+0x20/0x78 [ 360.502877] el0_svc+0x48/0xf8 [ 360.505977] el0t_64_sync_handler+0x88/0xb0 [ 360.510216] el0t_64_sync+0x148/0x14c [ 360.513930] irq event stamp: 4306 [ 360.517288] hardirqs last enabled at (4305): [<ffff8000080b0300>] __cancel_work_timer+0x130/0x1b0 [ 360.526359] hardirqs last disabled at (4306): [<ffff800008d194fc>] el1_dbg+0x24/0x88 [ 360.534204] softirqs last enabled at (4278): [<ffff8000080104a0>] _stext+0x4a0/0x5e0 [ 360.542133] softirqs last disabled at (4267): [<ffff8000080932ac>] irq_exit_rcu+0x18c/0x1b0 [ 360.550591] ---[ end trace 0000000000000000 ]--- Signed-off-by: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com> Link: https://lore.kernel.org/r/20220524135822.14764-1-prabhakar.mahadev-lad.rj@bp.renesas.com Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

2022-05-18Input: vmmouse - disable vmmouse before entering suspend modeZongmin Zhou
Currently, when trying to suspend and resume with VirtualPS/2 VMMouse there is an error message after resuming: psmouse serio1: vmmouse: Unable to re-enable mouse when reconnecting, err: -6 and the mouse will no longer be operable, requiring full rescan to find a another driver to use for the port. This error is due to QEMU still generating PS2 events which the kernel is not consuming until resume time, where they interfere with mouse identification and ultimately resulting in an error getting VMMOUSE_VERSION_ID. Test scenario: 1) start virtual machine with qemu command "vmport=on" 2) click suspend botton to enter suspend mode 3) resume and observe the error message in the kernel logs Let's fix this by disabling the vmmouse in its reset handler. This will notify qemu to stop vmmouse and remove the handler.

2022-05-18Input: ili210x - fix reset timingMarek Vasut
According to Ilitek "231x & ILI251x Programming Guide" Version: 2.30 "2.1. Power Sequence", "T4 Chip Reset and discharge time" is minimum 10ms and "T2 Chip initial time" is maximum 150ms. Adjust the reset timings such that T4 is 12ms and T2 is 160ms to fit those figures. This prevents sporadic touch controller start up failures when some systems with at least ILI251x controller boot, without this patch the systems sometimes fail to communicate with the touch controller.

2022-05-17Input: cros-ec-keyb - allow skipping keyboard registrationStephen Boyd
If the device is a detachable (and therefore lacks full keyboard), we may still want to load this driver because the device might have some other buttons or switches (e.g. volume and power buttons or a tablet mode switch). In such case we do not want to register the "main" keyboard device to allow userspace detect when the detachable keyboard is disconnected and adjust the system behavior for the tablet mode. Originally it was suggested to simply skip keyboard registration if row and columns properties didn't exist, but that approach did not convey the intent strongly enough and also had a slight problem for migrating existing DTBs without updating the kernel first, so it was decided to introduce new google,cros-ec-keyb-switches to explicitly mark devices that only have axillary buttons and switches.
