Adds serdev_device_set_parity() and an implementation for ttyport. The interface uses an enum with the values SERIAL_PARITY_NONE, SERIAL_PARITY_EVEN and SERIAL_PARITY_ODD.

serdev: only match serdev devices

2018-01-22T13:19:10Z

Only serdev devices (a.k.a. clients or slaves) are bound to drivers so bail out early from match() in case the device is not a serdev device (i.e. if it's a serdev controller). Signed-off-by: Johan Hovold Reviewed-by: Sebastian Reichel Signed-off-by: Greg Kroah-Hartman

serdev: do not generate modaliases for controllers

2018-01-22T13:17:44Z

Serdev controllers are not bound to any drivers and it therefore makes no sense to generate modaliases for them. This has already been fixed separately for ACPI controllers for which uevent errors were also being logged during probe due to the missing ACPI companions (from which ACPI modaliases are generated). This patch moves the modalias handling from the bus type to the client device type. Specifically, this means that only serdev devices (a.k.a. clients or slaves) will have have MODALIAS fields in their uevent environments and corresponding modalias sysfs attributes. Also add the missing static keyword for the modalias device attribute when moving the definition.

serdev: Fix serdev_uevent failure on ACPI enumerated serdev-controllers

2018-01-09T15:49:27Z

ACPI enumerated serdev-controllers do not have an ACPI companion, the ACPI companion belongs to the serdev-device child of the serdev-controller, not to the controller itself. This was causing serdev_uevent to always return -ENODEV when called on a serdev-controller leading to errors like these: kernel: serial serial0: uevent: failed to send synthetic uevent being logged. This commit modifies serdev_uevent to directly return 0 when called on an ACPI enumerated serdev-controller fixing this. Note: I do not think that setting a modalias on a devicetree enumerated serdev-controller makes sense either. So perhaps the !dev->of_node part of the check can be dropped too, but I'm not entirely sure that doing this on devicetree too is correct.
