Message-Id: <1386901645-28895-1-git-send-email-ynvich@gmail.com> Date: Fri, 13 Dec 2013 06:27:09 +0400 From: Sergei Ianovich <ynvich@...il.com> To: linux-kernel@...r.kernel.org, linux-arm-kernel@...ts.infradead.org Cc: Sergei Ianovich <ynvich@...il.com>, Daniel Mack <zonque@...il.com>, Arnd Bergmann <arnd@...db.de>, Haojian Zhuang <haojian.zhuang@...il.com> Subject: [PATCH v2 00/16] ARM: support for ICP DAS LP-8x4x (with dts) Fixed most review requirements. Details in respective patches. I've completely met the requirement for using dmaengine-based DMA in patch v2-03/16. Tests showed new DMA was underperforming. It added on top of a pre-existing problem with MMC bus width and made the system barely usable. However, the new code in this patch work correctly with both the existing and the new DMA. Even if the new DMA is compiled into the kernel, the exisitng DMA initializes first. I've also decided not to create a single mfd device for machine-specific devices. Instead each type is supported by a separate driver in respective subsystem. It was tempting to hardcode all the constants in one source file, but that requires ugly initialization. The taken way produces much cleaner code.
