Hello,
Following the introduction of scatter-gather support of Xilinx's XDMA IP
in the Linux kernel, here is a small series adding cyclic transfers.
The first patch is a preparation patch to ease the review of the second
one which actually adds cyclic transfers support.
Thanks,
Miquèl
Changes in v2:
* Rebased on top of v6.6-rc1
* Removed the if (!state) superfluous check.
* Address a kernel test robot report (unitialized variable in error case)
* Simplify the convoluted logic when filling the hardware descriptors
