Subject[PATCH v2 0/6] net: stmmac: make DMA programmable burst length more configurable
Date
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
