net: Add a layer for non-PHY MII time stamping drivers.

2019-12-26T03:51:33+00:00

While PHY time stamping drivers can simply attach their interface directly to the PHY instance, stand alone drivers require support in order to manage their services. Non-PHY MII time stamping drivers have a control interface over another bus like I2C, SPI, UART, or via a memory mapped peripheral. The controller device will be associated with one or more time stamping channels, each of which sits snoops in on a MII bus. This patch provides a glue layer that will enable time stamping channels to find their controlling device. Signed-off-by: Richard Cochran Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller

net: Introduce a new MII time stamping interface.

Currently the stack supports time stamping in PHY devices. However, there are newer, non-PHY devices that can snoop an MII bus and provide time stamps. In order to support such devices, this patch introduces a new interface to be used by both PHY and non-PHY devices. In addition, the one and only user of the old PHY time stamping API is converted to the new interface. Signed-off-by: Richard Cochran Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller
