From: Niklas Cassel <niklas.cassel@axis.com>
Make DMA programmable burst length more configurable in the stmmac driver.
This is done by adding support for independent pbl for tx/rx through DT. More fine grained tuning of pbl is possible thanks to a DT property saying that we should NOT multiply pbl values by x8/x4 in hardware.
All new DT properties are optional, and created in a way that it will not affect any existing DT configurations.
Changes since V1: Created cover-letter. Rebased patch set against next-20161205, since conflicting patches to stmmac_platform.c has been merged since V1.
Niklas Cassel (6): net: stmmac: return error if no DMA configuration is found net: stmmac: simplify the common DMA init API net: stmmac: stmmac_platform: fix parsing of DT binding net: stmmac: dwmac1000: fix define DMA_BUS_MODE_RPBL_MASK net: stmmac: add support for independent DMA pbl for tx/rx net: smmac: allow configuring lower pbl values
