2017-01-08Documentation: DT: net: cpsw: remove no_bd_ram propertyGrygorii Strashko1-3/+0
Even if no_bd_ram property is described in TI CPSW bindings the support for it has never been introduced in CPSW driver, so there are no real users of it. Hence, remove no_bd_ram property from documentation and DT files. Cc: 'Rob Herring <robh+dt@kernel.org>' Signed-off-by: Grygorii Strashko <grygorii.strashko@ti.com> Signed-off-by: David S.

2016-12-07net: ethernet: ti: cpts: calc mult and shift from refclk freqGrygorii Strashko1-3/+5
The cyclecounter mult and shift values can be calculated based on the CPTS rfclk frequency and timekeepnig framework provides required algos and API's. Hence, calc mult and shift basing on CPTS rfclk frequency if both cpts_clock_shift and cpts_clock_mult properties are not provided in DT (the basis of calculation algorithm is borrowed from __clocksource_update_freq_scale() commit 7d2f944a2b83 ("clocksource: Provide a generic mult/shift factor calculation")). After this change cpts_clock_shift and cpts_clock_mult DT properties will become optional.

2016-06-18Documentation: DT: cpsw: remove rx_descs propertyIvan Khoronzhuk1-1/+0
There is no reason to hold s/w dependent parameter in device tree. Even more, there is no reason in this parameter because davinici_cpdma driver splits pool of descriptors equally between tx and rx channels anyway.

2016-04-29dt: cpsw: phy-handle, phy_id, and fixed-link are mutually exclusiveDavid Rivshin1-3/+3
The phy-handle, phy_id, and fixed-link properties are mutually exclusive, and only one need be specified. Make this clear in the binding doc. Also mark the phy_id property as deprecated, as phy-handle should be used instead.

2015-12-18drivers: net: cpsw: fix RMII/RGMII mode when used with fixed-link PHYDavid Rivshin1-3/+3
Commit 1f71e8c96fc654724723ce987e0a8b2aeb81746d ("drivers: net: cpsw: Add support for fixed-link PHY") did not parse the "phy-mode" property in the case of a fixed-link PHY, leaving slave_data->phy_if with its default of PHY_INTERFACE_MODE_NA(0). This later gets passed to phy_connect() in cpsw_slave_open(), and eventually to cpsw_phy_sel() where it hits a default case that configures the MAC for MII mode. The user visible symptom is that while kernel log messages seem to indicate that the interface is set up, there is no network communication. Eventually a watchdog error occurs: NETDEV WATCHDOG: eth0 (cpsw): transmit queue 0 timed out Fixes: 1f71e8c96fc6 ("drivers: net: cpsw: Add support for fixed-link PHY") Signed-off-by: David Rivshin <drivshin@allworx.com> Signed-off-by: David S.

2015-09-15drivers: net: cpsw: Add support to drive gpios for ethernet to be functionalMugunthan V N1-0/+7
In DRA72x EVM, by default slave 1 is connected to the onboard phy, but slave 2 pins are also muxed with video input module which is controlled by pcf857x gpio and currently to select slave 0 to connect to phy gpio hogging is used, but with omap2plus_defconfig the pcf857x gpio is built as module. So when using NFS on DRA72x EVM, board doesn't boot as gpio hogging do not set proper gpio state to connect slave 0 to phy as it is built as module and you do not see any errors for not setting gpio and just mentions dhcp reply not got. To solve this issue, introducing "mode-gpios" in DT when gpio based muxing is required. This will throw a warning when gpio get fails and returns probe defer. When gpio-pcf857x module is installed, cpsw probes again and ethernet becomes functional. Verified this on DRA72x with pcf as module and ramdisk.

2014-02-19DT: net: document Ethernet bindings in one placeSergei Shtylyov1-3/+2
This patch is an attempt to gather the Ethernet related bindings in one file, like it's done in the MMC and some other subsystems. It should save some of the trouble of documenting several properties over and over in each binding document, instead only making reference to the main file. I have used the Embedded Power Architecture(TM) Platform Requirements (ePAPR) standard as a base for the properties description, also documenting some ad-hoc properties that have been introduced over time despite having direct analogs in ePAPR.
