Before commit 035a61c314eb ("clk: Make clk API return per-user struct clk instances") we acquired the enable_lock in __clk_set_parent_{before,after}() by means of calling clk_enable(). After commit 035a61c314eb we use clk_core_enable() in place of the clk_enable(), and clk_core_enable() doesn't acquire the enable_lock.

Commit ae43b3289186 ("ARM: 8202/1: dmaengine: pl330: Add runtime Power Management support v12") added pm support for the pl330 dma driver but it makes the clock for the Exynos5420 MDMA0 DMA controller to be gated during suspend and this in turn makes its parent clock aclk266_g2d to be gated. But the clock needs to be ungated prior suspend to allow the system to be suspend and resumed correctly. Add GATE_BUS_TOP register to the list of registers to be restored when the system enters into a suspend state so aclk266_g2d will be ungated. Thanks to Abhilash Kesavan for figuring out that this was the issue.
