net: phy: Convert some PHY and MDIO driver files to SPDX headers

2019-01-23T04:53:08Z

Where the license text and the MODULE_LICENSE() value agree, convert to using an SPDX header, removing the license text. Signed-off-by: Andrew Lunn Signed-off-by: David S. Miller

net: phy: broadcom: Fix bcm_write_exp()

2018-05-23T19:27:01Z

On newer PHYs, we need to select the expansion register to write with setting bits [11:8] to 0xf. This was done correctly by bcm7xxx.c prior to being migrated to generic code under bcm-phy-lib.c which unfortunately used the older implementation from the BCM54xx days. Fix this by creating an inline stub: bcm_write_exp_sel() which adds the correct value (MII_BCM54XX_EXP_SEL_ER) and update both the Cygnus PHY and BCM7xxx PHY drivers which require setting these bits. broadcom.c is unchanged because some PHYs even use a different selector method, so let them specify it directly (e.g: SerDes secondary selector).

net: phy: broadcom: Add support code for reading PHY counters

2016-11-30T15:22:27Z

Broadcom PHYs expose a number of PHY error counters: receive errors, false carrier sense, SerDes BER count, local and remote receive errors. Add support code to allow retrieving these error counters. Since the Broadcom PHY library code is used by several drivers, make it possible for them to specify the storage for the software copy of the statistics.

net: phy: broadcom: Allow enabling or disabling of EEE

2016-11-24T20:45:53Z

In preparation for adding support for Wirespeed/downshift, we need to change bcm_phy_eee_enable() to allow enabling or disabling EEE, so make the function take an extra enable/disable boolean parameter and rename it to illustrate it sets EEE, not necessarily just enables it.

net: phy: broadcom: Add support code for downshift/Wirespeed

2016-11-24T20:45:53Z

Broadcom's Wirespeed feature allows us to configure how auto-negotiation should behave with fewer working pairs of wires on a cable. Add support code for retrieving and setting such downshift counters using the recently added ethtool downshift tunables. Signed-off-by: Florian Fainelli Signed-off-by: David S. Miller

net: phy: broadcom: Move bcm54xx_auxctl_{read, write} to common library

2016-11-24T20:45:53Z

We are going to need these functions to implement support for Broadcom Wirespeed, aka downshift. Signed-off-by: Florian Fainelli Signed-off-by: David S. Miller

net: phy: Add Broadcom phy library for common interfaces

2015-10-08T11:45:46Z

This patch adds the Broadcom phy library to consolidate common interfaces shared by Broadcom phy's. Moved the common interfaces to the 'bcm-phy-lib.c' and updated the Broadcom PHY drivers to use the new APIs. Signed-off-by: Arun Parameswaran Signed-off-by: David S. Miller
