From mboxrd@z Thu Jan 1 00:00:00 1970 From: Heiner Kallweit Subject: [PATCH 0/2] spi: fsl-(e)spi: migrate to generic master queueing Date: Wed, 03 Dec 2014 07:56:10 +0100 Message-ID: <547EB40A.7070909@gmail.com> Mime-Version: 1.0 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 7bit Cc: linux-spi-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: broonie-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org Return-path: Sender: linux-spi-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org List-ID: Patch 1/2 Migrates the fsl-(e)spi driver to use the generic master queuing. Avoids the "master is unqueued, this is deprecated" warning. Patch 2/2 Adds (un)prepare_transfer_hardware calls to (re)set SPMODE_ENABLE. Reduces power consumption when SPI is idle. I successfully tested the backported version of both patches on a wireless router TP-Link TL-WDR4900 (P1014/mpc85xx-based: fsl-espi) with openwrt and kernel 3.14.25 (newer kernels not yet supported). Due to missing hw I wasn't able to test patch 1 with fsl-spi.
