2020-08-21T08:53:06+00:00

[ Upstream commit ce054039ba5e47b75a3be02a00274e52b06a6456 ] Clean up receive processing by dropping the character pointer and keeping the length argument unchanged throughout the function. Also make it more apparent that sysrq processing can consume a characters by adding an explicit continue. Reviewed-by: Greg Kroah-Hartman Signed-off-by: Johan Hovold Signed-off-by: Sasha Levin

USB: serial: ch341: add new Product ID for CH340

2020-07-22T07:10:06+00:00

commit 5d0136f8e79f8287e6a36780601f0ce797cf11c2 upstream. Add PID for CH340 that's found on some ESP8266 dev boards made by LilyGO. The specific device that contains such serial converter can be seen here: https://github.com/LilyGO/LILYGO-T-OI. Apparently, it's a regular CH340, but I've confirmed with others that also bought this board that the PID found on this device (0x7522) differs from other devices with the "same" converter (0x7523). Simply adding its PID to the driver and rebuilding it made it work as expected. Signed-off-by: Igor Moura Cc: stable@vger.kernel.org Signed-off-by: Johan Hovold Signed-off-by: Greg Kroah-Hartman

USB: serial: cypress_m8: enable Simply Automated UPB PIM

2020-07-22T07:10:06+00:00

commit 5c45d04c5081c1830d674f4d22d4400ea2083afe upstream. This is a UPB (Universal Powerline Bus) PIM (Powerline Interface Module) which allows for controlling multiple UPB compatible devices from Linux using the standard serial interface. Based on vendor application source code there are two different models of USB based PIM devices in addition to a number of RS232 based PIM's. The vendor UPB application source contains the following USB ID's: #define USB_PCS_VENDOR_ID 0x04b4 #define USB_PCS_PIM_PRODUCT_ID 0x5500 #define USB_SAI_VENDOR_ID 0x17dd #define USB_SAI_PIM_PRODUCT_ID 0x5500 The first set of ID's correspond to the PIM variant sold by Powerline Control Systems while the second corresponds to the Simply Automated Incorporated PIM. As the product ID for both of these match the default cypress HID->COM RS232 product ID it assumed that they both use an internal variant of this HID->COM RS232 converter hardware. However as the vendor ID for the Simply Automated variant is different we need to also add it to the cypress_M8 driver so that it is properly detected.
