Apparently you have missed the previous RFC iteration, the MFD/SPI drivers posted at end of May: https://patchwork.kernel.org/patch/10969211/ https://patchwork.kernel.org/patch/10969213/ https://patchwork.kernel.org/patch/10969217/ There's not yet merged MTD patch you'd need too: http://patchwork.ozlabs.org/patch/1199645/ The MFD driver was shot down by Lee Jones who has advised placing the common code into drivers/memory/ instead... I don't want to re-post the SPI driver as I haven't yet addressed all of Mark Brown's comments... > If there was a complete patch set that I could try on the RZ/A SoCs and > get a working SPI MTD device to show up, then I would drop my efforts of > getting my driver in and just add RZ/A support to the R-Car driver. Please try these patches, there's a big chance they'll work. [...] > Honestly, I'll be out of the office until January, so it's not like I'm > going to do anything with it until then.

Have happy holidays! (Ours happen on 1/1 and last till 1/8 this year.) > Chris MBR, Sergei
