of hid_have_special_driver[] Most HID devices behave properly when they are used with hid-generic. Since kernel v4.12, we do not poll for input reports at plug in, so hid-generic should behave properly with all HID devices. There has been a long standing list of HID devices that have a special driver. It used to be just a few, but with time, this list went too big, and we can not ask users to know which HID special driver will pick up their device. We can teach hid-generic to be nice with others. If a device is not explicitly marked with HID_QUIRK_HAVE_SPECIAL_DRIVER, we can allow hid-generic to pick up the device as long as no other loaded HID driver will match the device. When the special driver appears, hid-generic can step back and let the special driver handling the device. In case this special driver is removed, this good old pal of hid-generic will rebind to the device. This basically makes the list hid_have_special_driver[] useless. It still allows to not see a hid-generic driver bound and removed during boot, so we can keep it around. This will also help other people to have a special HID driver without the need of recompiling hid-core.

charset=UTF-8 Content-Transfer-Encoding: 8bit Ages ago Rob Clark noted, "Currently with fence-array, we have a potential deadlock situation. If we fence_add_callback() on an array-fence, the array-fence's lock is acquired first, and in it's ->enable_signaling() callback, it will install cbs on it's array-member fences, so the array-member's lock is acquired second. But in the signal path, the array-member's lock is acquired first, and the array-fence's lock acquired second." Rob proposed either extensive changes to dma-fence to unnest the fence-array signaling, or to defer the signaling onto a workqueue. This is a more refined version of the later, that should keep the latency of the fence signaling to a minimum by using an irq-work, which is executed asap.

USB "interface nodes" are children of USB "device nodes" and are identified by an interface number and a configuration value: &usb1 { /* host controller */ dev1: device@1 { /* device at port 1 */ compatible = "usb1234,5678"; reg = <1>; #address-cells = <2>; #size-cells = <0>; interface@0,2 { /* interface 0 of configuration 2 */ compatible = "usbif1234,5678.config2.0"; reg = <0 2>; }; }; }; The configuration component is not included in the textual representation of an interface-node unit address for configuration 1: &dev1 { interface@0 { /* interface 0 of configuration 1 */ compatible = "usbif1234,5678.config1.0"; reg = <0 1>; }; }; When a USB device of class 0 or 9 (hub) has only a single configuration with a single interface, a special case "combined node" is used instead of a device node with an interface node: &usb1 { device@2 { compatible = "usb1234,abcd"; reg = <2>; }; }; Combined nodes are shared by the two device structures representing the USB device and its interface in the kernel's device model. Note that, as for device nodes, the compatible strings for interface nodes are currently not used. For more details see "Open Firmware Recommended Practice: Universal Serial Bus Version 1" and the binding documentation.

Give the helper the more descriptive name usb_of_get_device_node(), which matches the new usb_of_get_interface_node() helper that is used to look up a second type of of child node from a USB device. Note that the terms "device node" and "interface node" are defined and used by the OF Recommended Practice for USB.

The function is therefore included on ACPI platforms as well even though it's not used. On the other hand ACPI platforms with rs485 do exist (e.g. Siemens IOT2040) and they may leverage _DSD to store rs485 properties. Likewise, UART platform devices instantiated from an MFD should be able to specify rs485 properties. In fact, the tty subsystem maintainer had asked for a "generic" function during review of commit ef838a81dd4d: https://marc.info/?l=linux-serial&m=150143441725194&w=4 Thus, instead of constraining the helper to OF platforms, make it platform-agnostic by converting it to device_property_*() functions and renaming it accordingly. In imx.c, move the invocation of uart_get_rs485_mode() from serial_imx_probe_dt() to serial_imx_probe() so that it also gets called for non-OF devices. In omap-serial.c, move its invocation further up within serial_omap_probe_rs485() so that the RTS polarity can be overridden with the driver-specific "rs485-rts-active-high" property once we introduce a generic "rs485-rts-active-low" property.

This makes it difficult to write upper layers as the caller has to assume whether the FPGA image is in a sg table, as a single buffer, or a firmware file. This commit moves these parameters to struct fpga_image_info and adds a single function for programming fpgas. New functions: * fpga_mgr_load - given fpga manager and struct fpga_image_info, program the fpga. * fpga_image_info_alloc - alloc a struct fpga_image_info. * fpga_image_info_free - free a struct fpga_image_info. These three functions are unexported: * fpga_mgr_buf_load_sg * fpga_mgr_buf_load * fpga_mgr_firmware_load Also use devm_kstrdup to copy firmware_name so we aren't making assumptions about where it comes from when allocing/freeing the struct fpga_image_info. API documentation has been updated and a new document for FPGA region has been added.
