USB: serial: add MaxLinear/Exar USB to Serial driver

2021-01-21T09:49:37+00:00

Add support for MaxLinear/Exar USB to Serial converters. This driver only supports XR21V141X series but it can be extended to other series from Exar as well in future. This driver is inspired from the initial one submitted by Patong Yang: https://lore.kernel.org/r/20180404070634.nhspvmxcjwfgjkcv@advantechmxl-desktop While the initial driver was a custom tty USB driver exposing whole new serial interface ttyXRUSBn, this version is completely based on USB serial core thus exposing the interfaces as ttyUSBn. This will avoid the overhead of exposing a new USB serial interface which the userspace tools are unaware of. The Exar XR21V141X can be used in either ACM mode using the cdc-acm driver or in "custom driver" mode in which further features such as hardware and software flow control, GPIO control and in-band line-status reporting are available. In ACM mode the device always enables RTS/CTS flow control, something which could prevent transmission in case the CTS input isn't wired up corrently. A follow-on patch will prevent cdc_acm from binding whenever this driver is enabled.

USB: serial: keyspan_pda: clean up xircom/entrega support

2020-11-04T10:01:49+00:00

Drop the separate Kconfig symbol for Xircom / Entrega and always include support in the keyspan_pda driver. Note that all configs that enabled CONFIG_USB_SERIAL_XIRCOM also enable CONFIG_USB_SERIAL_KEYSPAN_PDA. Acked-by: Sebastian Andrzej Siewior Reviewed-by: Greg Kroah-Hartman Signed-off-by: Johan Hovold

treewide: replace '---help---' in Kconfig files with 'help'

2020-06-13T16:57:21+00:00

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by: Masahiro Yamada

docs: usb: rename files to .rst and add them to drivers-api

2019-06-20T12:28:36+00:00

While there are a mix of things here, most of the stuff were written from Kernel developer's PoV. So, add them to the driver-api book. A follow up for this patch would be to move documents from there that are specific to sysadmins, adding them to the admin-guide.

Pull driver core updates from Greg KH: "Here is the set of "big" driver core patches for 4.16-rc1. The majority of the work here is in the firmware subsystem, with reworks to try to attempt to make the code easier to handle in the long run, but no functional change. There's also some tree-wide sysfs attribute fixups with lots of acks from the various subsystem maintainers, as well as a handful of other normal fixes and changes. And finally, some license cleanups for the driver core and sysfs code.
