USB: serial: pl2303: add support for PL2303HXN

2019-10-23T08:52:16Z

Prolific has developed a new USB to UART chip: PL2303HXN PL2303HXN : PL2303GC/PL2303GS/PL2303GT/PL2303GL/PL2303GE/PL2303GB The Vendor request used by the PL2303HXN (TYPE_HXN) is different from the existing PL2303 series (TYPE_HX & TYPE_01). Therefore, different Vendor requests are used to issue related commands. 1. Added a new TYPE_HXN type in pl2303_type_data, and then executes new Vendor request,new flow control and other related instructions if TYPE_HXN is recognized. 2. Because the new PL2303HXN only accept the new Vendor request, the old Vendor request cannot be accepted (the error message will be returned) So first determine the TYPE_HX or TYPE_HXN through PL2303_READ_TYPE_HX_STATUS in pl2303_startup. 2.1 If the return message is "1", then the PL2303 is the existing TYPE_HX/ TYPE_01 series. The other settings in pl2303_startup are to continue execution. 2.2 If the return message is "not 1", then the PL2303 is the new TYPE_HXN series. The other settings in pl2303_startup are ignored. (PL2303HXN will directly use the default value in the hardware, no need to add additional settings through the software) 3. In pl2303_open: Because TYPE_HXN is different from the instruction of reset down/up stream used by TYPE_HX. Therefore, we will also execute different instructions here. 4. In pl2303_set_termios: The UART flow control instructions used by TYPE_HXN/TYPE_HX/TYPE_01 are different. Therefore, we will also execute different instructions here. 5. In pl2303_vendor_read & pl2303_vendor_write, since TYPE_HXN is different from the vendor request instruction used by TYPE_HX/TYPE_01, it will also execute different instructions here. 6. In pl2303_update_reg: TYPE_HXN used different register for flow control. Therefore, we will also execute different instructions here. Signed-off-by: Charles Yeh Signed-off-by: Johan Hovold

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

2019-06-20T12:28:36Z

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.

USB: serial: pl2303: fix tranceiver suspend mode

2019-04-03T07:46:50Z

Add helper function to update register bits instead of overwriting the entire control register when updating the flow-control settings. This specifically avoids having the tranceiver suspend mode (bit 0) depend on the flow control setting. The tranceiver is currently configured at probe to be disabled during suspend, but this was overridden when disabling flow control or enabling xon/xoff.

USB: serial: pl2303: fix non-supported xon/xoff

2019-04-03T07:46:22Z

Older pl2303 devices do not support automatic xon/xoff flow control, so add add a flag to prevent trying to enable it for legacy device types. Refactor the IXON test into a helper function to improve readability.
