Subject: [PATCHv2 0/6] dw_dmac: introduce autoconfiguration
Date: Fri, 21 Sep 2012 15:05:43 +0300 [thread overview]
Message-ID: <1348229149-29040-1-git-send-email-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <1347867577-13170-1-git-send-email-andriy.shevchenko@linux.intel.com>
Here is a patchset that allows to adapt the driver to the hardware
configuration during probe time. The hardware should have the specific optional
parameters enabled. Otherwise the driver will consider values stored in the
platform data.
Additionally it brings support of the software LLP transfers. It means that
normal linked list transfer is substituted by set of single block transfers
transparently to the user.
Since v1:
- addressed all Viresh's comments.
Andy Shevchenko (6):
dw_dmac: mark dwc_dump_chan_regs as inline
dw_dmac: fill optional encoded parameters in register structure
dw_dmac: get number of channels from hardware if possible
dw_dmac: autoconfigure block_size or use platform data
dw_dmac: autoconfigure data_width or get it via platform data
dw_dmac: introduce software emulation of LLP transfers
