This patch replaces cases of: devm_kzalloc(handle, a * b, gfp) with: devm_kcalloc(handle, a * b, gfp) as well as handling cases of: devm_kzalloc(handle, a * b * c, gfp) with: devm_kzalloc(handle, array3_size(a, b, c), gfp) as it's slightly less ugly than: devm_kcalloc(handle, array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: devm_kzalloc(handle, 4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant.

* net: phy: dp83822: use BMCR_ANENABLE instead of BMSR_ANEGCAPABLE for DP83620Alvaro Gamez Machado2018-06-101-6/+29
| | | | | | | | | | | | | | | | | | | | | DP83620 register set is compatible with the DP83848, but it also supports 100base-FX. When the hardware is configured such as that fiber mode is enabled, autonegotiation is not possible. The chip, however, doesn't expose this information via BMSR_ANEGCAPABLE. Instead, this bit is always set high, even if the particular hardware configuration makes it so that auto negotiation is not possible [1]. Under these circumstances, the phy subsystem keeps trying for autonegotiation to happen, without success. Hereby, we inspect BMCR_ANENABLE bit after genphy_config_init, which on reset is set to 0 when auto negotiation is disabled, and so we use this value instead of BMSR_ANEGCAPABLE.

| | | | | | | | | | | | | BCM54612E have 4 multi-functional LED pins that can be configured through register setting; the LED4 pin can be configured to a 125MHz reference clock output by setting the spare register. Since the dedicated CLK125 reference clock pin is not brought out on the 48-Pin MLP, the LED4 pin is the only pin to provide such function in this package, and therefore it is beneficial to just enable the reference clock by default.

* net: phy: remove PM ops from MDIO busHeiner Kallweit2018-06-051-48/+0
| | | | | | | | | | | | | | | | | | | | | | | | | Current implementation of MDIO bus PM ops doesn't actually implement bus-specific PM ops but just calls PM ops defined on a device level what doesn't seem to be fully in line with the core PM model. When looking e.g. at __device_suspend() the PM core looks for PM ops of a device in a specific order: 1. device PM domain 2. device type 3. device class 4. device bus I think it has good reason that there's no PM ops on device level. Now that a device type representation of PHY's as special type of MDIO devices was added (only user of MDIO bus PM ops), the MDIO bus PM ops can be removed including member pm of struct mdio_device. If for some other type of MDIO device PM ops are needed, it should be modeled as struct device_type as well. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: David S.

| | | | | | | | | | | A PHY is a type of MDIO device, so let's model it as struct device_type and place PM ops, attribute groups and release callback on device type level. For this the attribute definitions have to be moved. This change allows us to get rid of the PM ops on a bus level in a second step.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

Fix this by using the appropriate selector mask which is defined (MII_BCM54XX_AUXCTL_SHDWSEL_MASK). This does not have a functional impact yet because we always access the MII_BCM54XX_AUXCTL_SHDWSEL_MISC (0x7) register in the current code. This might change at some point though.

The clock signal must meet the RGMII requirements to ensure the correct data transmission between the MAC and the PHY. The KSZ9031 phy does not fulfill the duty cycle requirement if the phy is configured as slave. For a complete describtion look at the errata sheets: DS80000691D or DS80000692D. The errata sheet recommends to force the phy into master mode whenever there is a 1000Base-T link-up as work around. Only set the "micrel,force-master" property if you use the phy reference clock provided by CLK125_NDO pin as MAC reference clock in your application. Attenation, this workaround is only usable if the link partner can be configured to slave mode for 1000Base-T.
