2015-01-21net: gem: Use phys_addr_t instead of int for addressesMichal Simek
Use phys_addr_t for physical address declaration. It is also unsigned type instead of sign. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
2014-05-06net: zynq: Fix sparse warnings in gemMichal Simek
Add missing header. Warnings: drivers/net/zynq_gem.c:491:5: warning: symbol 'zynq_gem_initialize' was not declared. Should it be static? drivers/net/zynq_gem.c:542:5: warning: symbol 'zynq_gem_of_init' was not declared. Should it be static? Signed-off-by: Michal Simek <michal.simek@xilinx.com>

2014-02-19net: zynq_gem: Calculate clock dividers dynamicallySoren Brinkmann
Remove hard coded clock divider setting and use the Zynq clock framework to dynamically calculate appropriate dividers at run time. Signed-off-by: Soren Brinkmann <soren.brinkmann@xilinx.com> Signed-off-by: Michal Simek <michal.simek@xilinx.com>
2014-02-19net: zynq_gem: Move RCLK details out of driverSoren Brinkmann
The GEM driver should not need to know about Zynq specific details of RCLK related registers and bitfields in the SLCR. Move those details to the slcr driver. Signed-off-by: Soren Brinkmann <soren.brinkmann@xilinx.com> Signed-off-by: Michal Simek <michal.simek@xilinx.com>
2014-01-21net: gem: Check if phy was correctly detectedMichal Simek
As tsec and fm drivers checking phydev->link ensure that u-boot don't try access device if link is not ready. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
2013-11-22net: zynq_gem: Add d-cache supportSrikanth Thokala
Added d-cache support for zynq_gem.c, Observed a difference of +0.8 MiB/s when downloading a file of size of 3007944Bytes. With d-cache OFF: ---------------- Filename 'uImage'. Load address: 0x800 Loading: ################################################################# ################################################################# ################################################################# ########## 1.3 MiB/s done Bytes transferred = 3007944 (2de5c8 hex) With d-cache ON: --------------- Filename 'uImage'. Load address: 0x800 Loading: ################################################################# ################################################################# ################################################################# ########## 2.1 MiB/s done Bytes transferred = 3007944 (2de5c8 hex) Changes on zynq_gem for d-cache support: - Tx and Rx buffers are cache-aligned - Updated logic for invalidating Rx buffers and flushing Tx buffers. - Tx and Rx BD's are allocated from non-cacheable region. (When BDs are cached, we don't see a consistent link) - Use TX BD status intead of txsr status checks.

2013-04-30net: gem: Fix gem driver on 1Gbps LANMichal Simek
The whole driver used 100Mbps because of zc702 rev B. Fix problem with not setup proper clock for gem1. This is generic approach for clk setup. Signed-off-by: Michal Simek <monstr@monstr.eu> Signed-off-by: Michal Simek <michal.simek@xilinx.com> Reviewed-by: Tom Rini <trini@ti.com>
2013-04-30net: gem: Do not initialize BDs againMichal Simek
BDs can be correctly setup just once and init function performs only phy autodetection and enabling RX/TX. RX/TX are disabled in halt function. This patch solves the problem with repeatable tftp transfers. Signed-off-by: Michal Simek <michal.simek@xilinx.com> Reviewed-by: Tom Rini <trini@ti.com>
