net: phy: smsc: enable edpd tunable support

2023-04-03T09:08:43Z

Enable EDPD PHY tunable support for all drivers using lan87xx_read_status. Signed-off-by: Heiner Kallweit Reviewed-by: Simon Horman Signed-off-by: David S. Miller

net: phy: smsc: add support for edpd tunable

2023-04-03T09:08:43Z

This adds support for the EDPD PHY tunable. Per default EDPD is disabled in interrupt mode, the tunable can be used to override this, e.g. if the link partner doesn't use EDPD. The interval to check for energy can be chosen between 1000ms and 2000ms. Note that this value consists of the 1000ms phylib interval for state machine runs plus the time to wait for energy being detected. v2: - consider that phylib core holds phydev->lock when calling the phy tunable hooks Signed-off-by: Heiner Kallweit Reviewed-by: Simon Horman Signed-off-by: David S.

net: phy: smsc: prepare for making edpd wait period configurable

2023-04-03T09:08:42Z

Add a member edpd_max_wait_ms to the private data structure in preparation of making the wait period configurable by supporting the edpd phy tunable. v2: - rename constant to EDPD_MAX_WAIT_DFLT_MS Signed-off-by: Heiner Kallweit Reviewed-by: Simon Horman Signed-off-by: David S. Miller

net: phy: smsc: add flag edpd_mode_set_by_user

2023-04-03T09:08:42Z

Add flag edpd_mode_set_by_user in preparation of adding edpd phy tunable support. This flag will allow users to override the default behavior of edpd being disabled if interrupt mode is used. Signed-off-by: Heiner Kallweit Reviewed-by: Simon Horman Signed-off-by: David S. Miller

net: phy: smsc: clear edpd_enable if interrupt mode is used

2023-04-03T09:08:42Z

Clear edpd_enable if interupt mode is used, this avoids having to check for PHY_POLL multiple times. Signed-off-by: Heiner Kallweit Reviewed-by: Simon Horman Signed-off-by: David S. Miller

net: phy: smsc: add helper smsc_phy_config_edpd

2023-04-03T09:08:42Z

Add helper smsc_phy_config_edpd() and explicitly clear bit MII_LAN83C185_EDPWRDOWN is edpd_enable isn't set. Boot loader may have left whatever value. Signed-off-by: Heiner Kallweit Reviewed-by: Simon Horman Signed-off-by: David S. Miller

net: phy: smsc: rename flag energy_enable

2023-04-03T09:08:42Z

Rename the flag to edpd_enable, as we're not enabling energy but edpd (energy detect power down) mode. In addition change the type to a bit field member in preparation of adding further flags. Signed-off-by: Heiner Kallweit Reviewed-by: Simon Horman Signed-off-by: David S. Miller

net: phy: smsc: export functions for use by meson-gxl PHY driver

2023-03-20T10:24:09Z

The Amlogic Meson internal PHY's have the same register layout as certain SMSC PHY's (also for non-c22-standard registers). This seems to be more than just coincidence. Apparently they also need the same workaround for EDPD mode (energy detect power down). Therefore let's export SMSC PHY driver functionality for use by the meson-gxl PHY driver.

net: phy: smsc: bail out in lan87xx_read_status if genphy_read_status fails

2023-03-15T07:19:16Z

If genphy_read_status fails then further access to the PHY may result in unpredictable behavior. To prevent this bail out immediately if genphy_read_status fails.
