From 8b0ae0b719d4ea9aee4ed3a7a09d5ff76557fadf Mon Sep 17 00:00:00 2001 From: Jassi Brar Date: Fri, 19 Nov 2010 08:49:43 +0900 Subject: ARM: S5PV310: Add platform devices for PL330 DMACs Samsung's Soc S5PV310 has three PL330 DMACs. First is dedicated for Memory->Memory data transfer while the other two meant for data transfer with peripherals. Define and add latter two PL330 DMACs as platform devices on the S5PV310 platform.

Actually, S5PV310 has same cache controller(PL310). Following is from Catalin Marinas' commit. Clearing bit 22 in the PL310 Auxiliary Control register (shared attribute override enable) has the side effect of transforming Normal Shared Non-cacheable reads into Cacheable no-allocate reads. Coherent DMA buffers in Linux always have a Cacheable alias via the kernel linear mapping and the processor can speculatively load cache lines into the PL310 controller. With bit 22 cleared, Non-cacheable reads would unexpectedly hit such cache lines leading to buffer corruption.
