* net: zynq: Fix sparse warnings in gemMichal Simek2014-05-06-0/+1
| | | | | | | | | | 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>

* net: zynq_gem: Calculate clock dividers dynamicallySoren Brinkmann2014-02-19-6/+11
| | | | | | | | 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>
* net: zynq_gem: Move RCLK details out of driverSoren Brinkmann2014-02-19-5/+2
| | | | | | | | | 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>
* net: gem: Check if phy was correctly detectedMichal Simek2014-01-21-0/+5

* net: zynq_gem: Add d-cache supportSrikanth Thokala2013-11-22-29/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
