dmi_use_low_level_irq Commit 223f61b8c5ad ("Input: soc_button_array - add Lenovo Yoga Tablet2 1051L to the dmi_use_low_level_irq list") added the 1051L to this list already, but the same problem applies to the 1051F. As there are no further 1051 variants (just the F/L), we can just DMI match 1051. Tested on a Lenovo Yoga Tablet2 1051F: Without this patch the home-button stops working after a wakeup from suspend.

2022-06-07Input: bcm5974 - set missing URB_NO_TRANSFER_DMA_MAP urb flagMathias Nyman1-1/+6
The bcm5974 driver does the allocation and dma mapping of the usb urb data buffer, but driver does not set the URB_NO_TRANSFER_DMA_MAP flag to let usb core know the buffer is already mapped. usb core tries to map the already mapped buffer, causing a warning: "xhci_hcd 0000:00:14.0: rejecting DMA map of vmalloc memory" Fix this by setting the URB_NO_TRANSFER_DMA_MAP, letting usb core know buffer is already mapped by bcm5974 driver Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Cc: stable@vger.kernel.org Link: https://bugzilla.kernel.org/show_bug.cgi?id=215890 Link: https://lore.kernel.org/r/20220606113636.588955-1-mathias.nyman@linux.intel.com Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

Instead of a virtual kernel address use a pointer of the associated struct page as second parameter of gnttab_end_foreign_access(). Most users have that pointer available already and are creating the virtual address from it, risking problems in case the memory is located in highmem. gnttab_end_foreign_access() itself won't need to get the struct page from the address again.

git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull ARMv4T/v5 multiplatform support from Arnd Bergmann: "This series has been 12 years in the making, it mostly finishes the work that was started with the founding of Linaro to clean up platform support in the kernel. The largest change here is a cleanup of the omap1 platform, which is the final ARM machine type to get converted to the common-clk subsystem. All the omap1 specific drivers are now made independent of the mach/*.h headers to allow the platform to be part of a generic ARMv4/v5 multiplatform kernel. The last bit that enables this support is still missing here while we wait for some last dependencies to make it into the mainline kernel through other subsystems. The s3c24xx, ixp4xx, iop32x, ep93xx and dove platforms were all almost at the point of allowing multiplatform kernels, this work gets completed here along with a few additional cleanup. At the same time, the s3c24xx and s3c64xx are now deprecated and expected to get removed in the future. The PXA and OMAP1 bits are in a separate branch because of dependencies. Once both branches are merged, only the three Intel StrongARM platforms (RiscPC, Footbridge/NetWinder and StrongARM1100) need separate kernels, and there are no plans to include these" * tag 'arm-multiplatform-5.19-1' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (61 commits) ARM: ixp4xx: Consolidate Kconfig fixing issue ARM: versatile: Add missing of_node_put in dcscb_init ARM: config: Refresh IXP4xx config after multiplatform ARM: omap1: add back omap_set_dma_priority() stub ARM: omap: fix missing declaration warnings ARM: omap: fix address space warnings from sparse ARM: spear: remove include/mach/ subdirectory ARM: davinci: remove include/mach/ subdirectory ARM: omap2: remove include/mach/ subdirectory integrator: remove empty ap_init_early() ARM: s3c: fix include path MAINTAINERS: omap1: Add Janusz as an additional maintainer ARM: omap1: htc_herald: fix typos in comments ARM: OMAP1: fix typos in comments ARM: OMAP1: clock: Remove noop code ARM: OMAP1: clock: Remove unused code ARM: OMAP1: clock: Fix UART rate reporting algorithm ARM: OMAP1: clock: Fix early UART rate issues ARM: OMAP1: Prepare for conversion of OMAP1 clocks to CCF ARM: omap1: fix build with no SoC selected ...

The commit 26623eea0da3 attempted to deal with potential leak of runtime PM counter when opening the touchscreen device, however it ended up erroneously dropping the counter in the case of successfully enabling the device. Let's address this by using pm_runtime_resume_and_get() and then executing pm_runtime_put_sync() only when we fail to send "sense on" command to the device.

2022-05-26Input: gpio-keys - cancel delayed work only in case of GPIOLad Prabhakar1-1/+1
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.

2022-05-19Input: vmmouse - disable vmmouse before entering suspend modeZongmin Zhou1-0/+14
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.

2022-05-19Input: ili210x - fix reset timingMarek Vasut1-2/+2
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 Boyd1-11/+18
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.

On certain PMICs, an unexpected assertion of KPDPWR_DEB (the positive logic hardware debounced power key signal) may be seen during the falling edge of KPDPWR_N (i.e. a power key press) when it occurs close to the rising edge of SLEEP_CLK.

If fwnode_property_count_u32() returns a negative error code then, because of type promotion, the "count > ARRAY_SIZE(pins)" condition will be true. The negative "count" is type promoted to a high unsigned size_t value. That means the "else if (count < 0)" condition will always be false and we don't print that error message or propagate the error code from fwnode_property_count_u32() as intended.
