driver/ldpaa_eth:Avoid infinite loop in ldpaa_eth_rx

2015-07-20T18:44:37Z

Change infinite loop mechanism to timer based polling for QBMAN release in ldpaa_eth_rx. Signed-off-by: Prabhakar Kushwaha Reviewed-by: York Sun

driver/ldpaa_eth: Avoid TX conf frames

2015-07-20T18:44:37Z

Polling of TX conf frames is not a mandatory option. Packets can be transferred via WRIOP without TX conf frame. Configure ldpaa_eth driver to use TX path without confirmation frame Signed-off-by: Prabhakar Kushwaha Acked-by: Joe Hershberger Reviewed-by: York Sun

driver/ldpaa_eth: Add timeout handling DQRR entry read

2015-07-20T18:44:37Z

Volatile command does not return frame immidiately, need to wait till a frame is available in DQRR. Ideally it should be a blocking call. Add timeout handling for DQRR frame instead of retry counter. Signed-off-by: Prabhakar Kushwaha Acked-by: Joe Hershberger Reviewed-by: York Sun

driver/ldpaa_eth: Retry enqueue if portal was busy

2015-07-20T18:44:37Z

Do not immediately return if the enqueue function returns -EBUSY; re-try mulitple times. if timeout occures, release the buffer. Signed-off-by: Prabhakar Kushwaha Acked-by: Joe Hershberger Reviewed-by: York Sun

driver/ldpaa_eth:Flush buffer before seeding BMAN after TX_conf

2015-07-20T18:44:36Z

Flush buffer before releasing to BMan after TX_conf to ensure, the core does not have any cachelines that the WRIOP will DMA to. Signed-off-by: Prabhakar Kushwaha Reviewed-by: York Sun

board/ls2085qds: Add support ethernet

2015-04-23T23:46:50Z

Add support of ethernet: - eth.c: mapping lane to slot for (0x2A, 0x07) - ls2085a.c: To enable/disable dpmac and get link type Signed-off-by: Prabhakar Kushwaha Signed-off-by: York Sun

driver/ldpaa: Add support of WRIOP static data structure

2015-04-23T15:55:58Z

Wire rate IO Processor (WRIOP) provide support of receive and transmit ethernet frames from the ethernet MAC. Here Each WRIOP block supports upto 64 DPMACs. Create a house keeping data structure to support upto 16 DPMACs and store external phy related information. Signed-off-by: Prabhakar Kushwaha Signed-off-by: York Sun

driver/ldpaa_eth: Update ldpaa ethernet driver

2015-04-23T15:55:56Z

Fix flush_dcache_range() input parameter to use start and end addresses. Change ethernet interface name to DPNI. Update entry criteria for ldpaa_eth_stop. Ethernet stack first stop the device before performing next operation. At the time of Ethernet driver registration, net_dev->state is set as ETH_STATE_INIT So take care net_dev->state as ETH_STATE_INIT in ldpaa_eth_stop. Undef CONFIG_PHYLIB temorarily because ldpaa_eth driver currently does not support PHYLIB. Instead of clearing pull descriptor one time, clear it before issuing any volatile dequeue command. Volatile command does not return frame immidiately, wait till a frame is available in DQRR. This frame can be valid or expired. Flush buffer before releasing to BMan ensure the core does not have any cachelines that the WRIOP will DMA to.

driver/ldpaa_eth: Add LDPAA Ethernet driver

2015-04-23T15:55:17Z

LDPAA Ethernet driver is a freescale's new ethernet driver based on Layerscape architecture. Every ethernet driver controls on DPNI object. Where all DPNIs share one common DPBP and DPIO object to support Rx and Tx flows. Signed-off-by: Prabhakar Kushwaha CC: Cristian Sovaiala CC: Bogdan Hamciuc CC: J.
