| * phy/micrel: Implement support for KSZ8021Marek Vasut2012-09-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | mdio: translation of MMD EEE registers to/from ethtool settingsAllan, Bruce W2012-08-23
|/ | | | | | | | | | | | | | | | | | | | | 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.

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.

PHYs following IEEE802.3 clause 45 have more than one device identifier constants, which breaks the default device matching code. Other 10G PHYs don't follow the standard manufacturer/device identifier register layout standards, but they do use the standard MDIO bus protocols for register access. Both of these require adjustments to the PHY driver to device matching code. If the there is an of_node associated with such a PHY, we can match it to its driver using the "compatible" properties, just as we do with certain platform devices. If the "compatible" property match fails, first check if there is a driver supplied matching function, and if not fall back to the existing identifier matching rules.

Already existing is the ability of MDIO bus drivers to use clause 45, with the MII_ADDR_C45 flag. Here we add struct phy_c45_device_ids to hold the device identifier registers present in clause 45. struct phy_device gets a couple of new fields: c45_ids to hold the identifiers and is_c45 to signal that it is clause 45. get_phy_device() gets a new parameter is_c45 to indicate that the PHY device should use the clause 45 protocol, and its callers are adjusted to pass false. The follow-on patch to of_mdio.c will pass true where appropriate. EXPORT phy_device_create() so that the follow-on patch to of_mdio.c can use it to create phy devices for PHYs, that have non-standard device identifier registers, based on the device tree bindings.

* netdev/of/phy: Add MDIO bus multiplexer support.David Daney2012-05-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a somewhat generic framework for MDIO bus multiplexers. It is modeled on the I2C multiplexer. The multiplexer is needed if there are multiple PHYs with the same address connected to the same MDIO bus adepter, or if there is insufficient electrical drive capability for all the connected PHY devices. Conceptually it could look something like this: ------------------ | Control Signal | --------+--------- | --------------- --------+------ | MDIO MASTER |---| Multiplexer | --------------- --+-------+---- | | C C h h i i l l d d | | --------- A B --------- | | | | | | | PHY@1 +-------+ +---+ PHY@1 | | | | | | | --------- | | --------- --------- | | --------- | | | | | | | PHY@2 +-------+ +---+ PHY@2 | | | | | --------- --------- This framework configures the bus topology from device tree data. The mechanics of switching the multiplexer is left to device specific drivers. The follow-on patch contains a multiplexer driven by GPIO lines.

* netdev/of/phy: New function: of_mdio_find_bus().David Daney2012-05-07
| | | | | | | | | | | | | | | | | | | | | Add of_mdio_find_bus() which allows an mii_bus to be located given its associated the device tree node. This is needed by the follow-on patch to add a driver for MDIO bus multiplexers. The of_mdiobus_register() function is modified so that the device tree node is recorded in the mii_bus. Then we can find it again by iterating over all mdio_bus_class devices. Because the OF device tree has now become an integral part of the kernel, this can live in mdio_bus.c (which contains the needed mdio_bus_class structure) instead of of_mdio.c.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes Auto Power Saving configuration in ip101a_config_init which was broken as there is no phy register write followed after setting IP101A_APS_ON flag. This patch also fixes the return value of ip101a_config_init. Without this patch ip101a_config_init returns 2 which is not an error accroding to IS_ERR and the mac driver will continue accessing 2 as valid pointer to phy_dev resulting in memory fault.

Originally the plan has been to create an all-new irq_domain implementation which addresses some of the powerpc shortcomings such as not handling 1:1 mappings well, but doing that proved to be far more difficult and invasive than generalizing the working code and refactoring it in-place. So, this branch rips out the 'new' irq_domain and replaces it with the modified powerpc version (in a fully bisectable way of course). It converts all users over to the new API and makes irq_domain selectable on any architecture. No architecture is forced to enable irq_domain, but the infrastructure is required for doing OpenFirmware style irq translations. It will even work on SPARC even though SPARC has it's own mechanism for translating irqs at boot time. MIPS, microblaze, embedded x86 and c6x are converted too. The resulting irq_domain code is probably still too verbose and can be optimized more, but that can be done incrementally and is a task for follow-on patches." * tag 'irqdomain-for-linus' of git://git.secretlab.ca/git/linux-2.6: (31 commits) dt: fix twl4030 for non-dt compile on x86 mfd: twl-core: Add IRQ_DOMAIN dependency devicetree: Add empty of_platform_populate() for !CONFIG_OF_ADDRESS (sparc) irq_domain: Centralize definition of irq_dispose_mapping() irq_domain/mips: Allow irq_domain on MIPS irq_domain/x86: Convert x86 (embedded) to use common irq_domain ppc-6xx: fix build failure in flipper-pic.c and hlwd-pic.c irq_domain/microblaze: Convert microblaze to use irq_domains irq_domain/powerpc: Replace custom xlate functions with library functions irq_domain/powerpc: constify irq_domain_ops irq_domain/c6x: Use library of xlate functions irq_domain/c6x: constify irq_domain structures irq_domain/c6x: Convert c6x to use generic irq_domain support. irq_domain: constify irq_domain_ops irq_domain: Create common xlate functions that device drivers can use irq_domain: Remove irq_domain_add_simple() irq_domain: Remove 'new' irq_domain in favour of the ppc one mfd: twl-core.c: Fix the number of interrupts managed by twl4030 of/address: add empty static inlines for !CONFIG_OF irq_domain: Add support for base irq and hwirq in legacy mappings ...
