* net: phy: Realtek RTL8211B/C PHY ID fixKarsten Merker2016-04-02-1/+2
| | | | | | | | | | | | | | | | | | | | | | | The RTL8211B_driver structure in drivers/net/phy/realtek.c contains a wrong PHY ID (0x1cc910 instead of 0x1cc912) in the uid field. The lowest four bits of the PHY ID encode the chip revision (B+C/D/E/F) of the RTL8211 and the code originally applied a mask of 0xfffff0 to the PHY ID, so that matching the PHY ID to the appropriate driver code was only done on the chip type (RTL8211), but not on a specific revision. After introduction of support for the RTL8211E, which needed another startup function than the older chip revisions, commit 42205047674d7fc9e0aa747273fbc7dcfbac3183 changed the mask to 0xffffff to make the chip revision relevant for the match, but didn't provide the now-relevant lower bits of the uid field for the RTL8211B/C. Fix this by setting the full PHY ID in the RTL8211B_driver uid field.

* net: phy: Optionally force master mode for RTL PHYMichael Haas2016-03-31-1/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces CONFIG_RTL8211X_PHY_FORCE_MASTER. If this define is set, RTL8211x PHYs (except for the RTL8211F) will have their 1000BASE-T master/slave autonegotiation disabled and forced to master mode. This is helpful for PHYs like the RTL8211C which produce unstable links in slave mode. Such problems have been found on the A20-Olimex-SOM-EVB and A20-OLinuXino-Lime2. There is no proper way to identify affected PHYs in software as the RTL8211C shares its UID with the RTL8211B. Thus, this fix requires the introduction of an #ifdef.

* net: phy: realtek: Use generic genphy_parse_link() for RTL8211EMichal Simek2016-02-22-1/+9
| | | | | | | | | | | | | | | | | | | | The problem with current implementation is that SPDDONE bit is 1 but link bit is zero. That's why phydev->link is setup to 0 which ending up in driver failure that link is not up. Log: Zynq> dhcp ethernet@e000b000 Waiting for PHY auto negotiation to complete....... done ethernet@e000b000: No link. There is at least 1ms delay between spddone bit and link up. Use genphy_read_status() instead of realtek implemenation which is working with page 11. Linux driver is also using generic implementation.

* net: phy: realtek: Disable interrupt on Realtek Ethernet PHY driversCodrin Ciubotariu2015-04-20-1/+17
| | | | | | | | | | | | | | | Some Realtek Ethernet PHYs, like RTL8211D(G/N) and RTL8211E(G), have interrupts enabled by default. If the interrupt is not treated later by the OS and the PHY's interrupt line is enabled and shared with other interrupts, the system will get an interrupt storm. This patch disables the interrupt for PHY devices that use one of the current Realtek Ethernet PHY drivers. Some of Realtek Ethernet PHYs, such as RTL8211B(L) have the interrupt masked. In this case, the functionality of the PHY should not be afected since this patch brings INER and INSR registers to their default values.

* net/phy: realtek: Fix the PHY ID mask to ensure the correct Realtek PHY is ↵Bhupesh Sharma2013-11-22-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | detected The 'get_phy_driver' code in 'drivers/net/phy/phy.c' uses the following method to determine which driver is to be loaded for a particular PHY module: list_for_each(entry, &phy_drivers) { drv = list_entry(entry, struct phy_driver, list); if ((drv->uid & drv->mask) == (phy_id & drv->mask)) return drv; } This means that a drv->mask of 0xfffff0 will return incorrect phy driver for the logic above, even if the drv->uid is anything other than something ending with a 0x0. For e.g. if the RTL8211E drv->uid is 0x1cc915 and drv->mask is 0xffffff and the RTL8211B drv->uid is 0x1cc910 and drv->mask is 0xffffff0, then the phy driver selected will always be RTL8211B even though the underlying phy connected on the board is a 8211E module. This patch fixes this issue. Signed-off-by: Bhupesh Sharma <bhupesh.sharma@freescale.com>
* net: phy/realtek: Add support for RTL8211DN and RTL8211E phy modulesBhupesh Sharma2013-08-19-26/+51
| | | | | | | | | | | | This patch adds support for Realtek PHY modules RTL8211DN and RTL8211E (variants: RTL8211E-VB-CG, RTL8211E-VL-CG, RTL8211EG-VB-CG), which can be found on Freescale's T1040RDB boards. To make the driver more generic across 8211 family, a generic name 8211x is added for macros and function names.

* phylib: Add a bunch of PHY drivers from tsecAndy Fleming2011-04-20-0/+130
The tsec driver had a bunch of PHY drivers already written. This converts them all into PHY Lib drivers, and serves as the first set of PHY drivers for PHY Lib. While doing that, cleaned up a number of magic numbers (though not all of them, as PHY vendors like to keep their numbers as magical as possible). Also, noticed that almost all of the vitesse/cicada PHYs had the same config/parse/startup functions, so those have been collapsed into one.
