phy: ocelot-serdes: fix out-of-bounds read

2018-10-23T02:27:14Z

Currently, there is an out-of-bounds read on array ctrl->phys, once variable i reaches the maximum array size of SERDES_MAX in the for loop. Fix this by changing the condition in the for loop from i <= SERDES_MAX to i < SERDES_MAX.

phy: phy-ocelot-serdes: fix return value check in serdes_probe()

2018-10-11T05:54:26Z

In case of error, the function syscon_node_to_regmap() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR().

phy: add driver for Microsemi Ocelot SerDes muxing

2018-10-05T21:36:44Z

The Microsemi Ocelot can mux SerDes lanes (aka macros) to different switch ports or even make it act as a PCIe interface. This adds support for the muxing of the SerDes. Signed-off-by: Quentin Schulz Signed-off-by: David S. Miller
