Subject: [PATCH v2 0/6] net: stmmac: make DMA programmable burst length more configurable
Date: Mon, 5 Dec 2016 10:10:32 +0100 [thread overview]
Message-ID: <1480929039-20257-1-git-send-email-niklass@axis.com> (raw)
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
