From 027f28b7bb589d726e3b6274a7d9272336522c65 Mon Sep 17 00:00:00 2001 From: Xiang Wang Date: Tue, 18 Jun 2013 14:55:58 +0800 Subject: [PATCH] dma: mmp_pdma: add protect when alloc/free phy channels In mmp pdma, phy channels are allocated/freed dynamically and frequently. But no proper protection is added. Conflict will happen when multi-users are requesting phy channels at the same time. Use spinlock to protect.
