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
