Toady I would like to qualify that statement. This patch makes use of the new 'num_chipselect' field of struct rspi_plat_data. This is not present in v3.12-rc7 but is present in linux-next. Thus I assume that it will appear in v3.13-rc1. With this in mind I will queue-up this patch after rebasing my branches on v3.13-rc1 once it has been released. -- To unsubscribe from this list: send the line "unsubscribe linux-sh" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

I have rebased my branches on top of v3.13-rc1 and re-queued-up this patch. -- To unsubscribe from this list: send the line "unsubscribe linux-sh" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Hi, could you please provide an update to the lager defconfig which enables the drivers for this.
