2019-10-18net: phy: micrel: Update KSZ87xx PHY nameMarek Vasut1-1/+1
The KSZ8795 PHY ID is in fact used by KSZ8794/KSZ8795/KSZ8765 switches. Update the PHY ID and name to reflect that, as this family of switches is commonly refered to as KSZ87xx Signed-off-by: Marek Vasut <marex@denx.de> Cc: Andrew Lunn <andrew@lunn.ch> Cc: David S.

This is adds support for the PHYs in the KSZ8795 5port managed switch. It will allow to detect the link between the switch and the soc and uses the same read_status functions as the KSZ8873MLL switch.

2016-07-15net: phy: micrel: Add KSZ8041FTL fiber mode supportPhilipp Zabel1-0/+1
We can't detect the FXEN (fiber mode) bootstrap pin, so configure it via a boolean device tree property "micrel,fiber-mode". If it is enabled, auto-negotiation is not supported. The only available modes are 100base-fx (full duplex and half duplex). Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-11-21net: phy: micrel: add generic clock-mode-select supportJohan Hovold1-1/+0
Add generic RMII-Reference-Clock-Select support. Several Micrel PHY have an RMII-Reference-Clock-Select bit to select 25 MHz or 50 MHz clock mode. Recently, support for configuring this through device tree for KSZ8021 and KSZ8031 was added. Generalise this support so that it can be configured for other PHY types as well. Note that some PHY revisions (of the same type) has this bit inverted. This should be either configurable through a new device-tree property, or preferably, determined based on PHY ID if possible. Also note that this removes support for setting 25 MHz mode from board files which was also added by the above mentioned commit 45f56cb82e45 ("net/phy: micrel: Add clock support for KSZ8021/KSZ8031").

2014-10-10net/phy: micrel: Add clock support for KSZ8021/KSZ8031Sascha Hauer1-0/+1
The KSZ8021 and KSZ8031 support RMII reference input clocks of 25MHz and 50MHz. Both PHYs differ in the default frequency they expect after reset. If this differs from the actual input clock, then register 0x1f bit 7 must be changed.

2013-12-11micrel: add support for KSZ8041RNLISergei Shtylyov1-0/+2
Renesas R-Car development boards use KSZ8041RNLI PHY which for some reason has ID of 0x00221537 that is not documented for KSZ8041-family PHYs and does not match the documented ID of 0x0022151x (where 'x' is the revision). We have to add the new #define PHY_ID_* and new ksphy_driver[] entry, almost the same as KSZ8041 one, differing only in the 'phy_id' and 'name' fields.

2012-09-24phy/micrel: Implement support for KSZ8021Marek Vasut1-0/+1
The KSZ8021 PHY was previously caught by KS8051, which is not correct. This PHY needs additional setup if it is strapped for address 0. In such case an reserved bit must be written in the 0x16, "Operation Mode Strap Override" register. According to the KS8051 datasheet, that bit means "PHY Address 0 in non-broadcast" and it indeed behaves as such on KSZ8021. The issue where the ethernet controller (Freescale FEC) did not communicate with network is fixed by writing this bit as 1. Signed-off-by: Marek Vasut <marex@denx.de> Cc: David J.
