mdio: translation of MMD EEE registers to/from ethtool settings

2012-08-23T05:58:27Z

The helper functions which translate IEEE MDIO Manageable Device (MMD) Energy-Efficient Ethernet (EEE) registers 3.20, 7.60 and 7.61 to and from the comparable ethtool supported/advertised settings will be needed by drivers other than those in PHYLIB (e.g. e1000e in a follow-on patch). In the same fashion as similar translation functions in linux/mii.h, move these functions from the PHYLIB core to the linux/mdio.h header file so the code will not have to be duplicated in each driver needing MMD-to-ethtool (and vice-versa) translations. The function and some variable names have been renamed to be more descriptive. Not tested on the only hardware that currently calls the related functions, stmmac, because I don't have access to any. Has been compile tested and the translations have been tested on a locally modified version of e1000e. Signed-off-by: Bruce Allan Cc: Giuseppe Cavallaro Signed-off-by: David S. Miller

phy: add the EEE support and the way to access to the MMD registers.

2012-07-01T10:34:50Z

This patch adds the support for the Energy-Efficient Ethernet (EEE) to the Physical Abstraction Layer. To support the EEE we have to access to the MMD registers 3.20 and 7.60/61. So two new functions have been added to read/write the MMD registers (clause 45). An Ethernet driver (I tested the stmmac) can invoke the phy_init_eee to properly check if the EEE is supported by the PHYs and it can also set the clock stop enable bit in the 3.0 register. The phy_get_eee_err can be used for reporting the number of time where the PHY failed to complete its normal wake sequence. In the end, this patch also adds the EEE ethtool support implementing: o phy_ethtool_set_eee o phy_ethtool_get_eee v1: initial patch v2: fixed some errors especially on naming convention v3: renamed again the mmd read/write functions thank to Ben's feedback v4: moved file to phy.c and added the ethtool support. v5: fixed phy_adv_to_eee, phy_eee_to_supported, phy_eee_to_adv return values according to ethtool API (thanks to Ben's feedback). Renamed some macros to avoid too long names. v6: fixed kernel-doc comments to be properly parsed. Fixed the phy_init_eee function: we need to check which link mode was autonegotiated and then the corresponding bits in 7.60 and 7.61 registers. v7: reviewed the way to get the negotiated settings. v8: fixed a problem in the phy_init_eee return value erroneously added when included the phy_read_status call. v9: do not remove the MDIO_AN_EEE_ADV_100TX and MDIO_AN_EEE_ADV_1000T and fixed the eee_{cap,lp,adv} declaration as "int" instead of u16.

mdio: Export mdio.h to userland

2012-03-01T21:41:22Z

The ID packing definitions are needed by userland and the register definitions may also be useful there. Do not export mdio_phy_id_{is_c45,prtad,devad}() as the use of bool is problematic and it's not that useful to export only a subset of these. Do not export MDIO_SUPPORTS_{C22,C45} directly; these flags are only exposed to userland through struct ethtool_cmd so they should be defined alongside that with appropriate names.

tg3: Move EEE definitions into mdio.h

2010-12-06T19:03:46Z

In commit 52b02d04c801fff51ca49ad033210846d1713253 entitled "tg3: Add EEE support", Ben Hutchings had commented that the EEE advertisement register will be in a standard location. This patch moves that definition into mdio.h and changes the code to use it. Signed-off-by: Matt Carlson Reviewed-by: Benjamin Li Signed-off-by: David S. Miller

mdio: mdio_if_info::mmds should not be __bitwise

2009-08-19T03:13:03Z

I misunderstood the meaning of __bitwise. In practice it makes sparse warn about every use of mmds which is certainly not what we want. Signed-off-by: Ben Hutchings Signed-off-by: David S. Miller
