This driver currently uses modular infrastructure but is controlled by a bool Kconfig. There is a general consensus from the DMA reviewers and maintainers that "if it can be modular, it should be modular" in order to keep the bzImage size under control for multi platform kernels. Build tested only. Also needed some new pm_clk symbols exported before this commit is applied to tree in order to avoid modpost errors like: ERROR: "pm_clk_add_clk" [drivers/dma/tegra210-adma.ko] undefined! ERROR: "pm_clk_create" [drivers/dma/tegra210-adma.ko] undefined! ERROR: "pm_clk_destroy" [drivers/dma/tegra210-adma.ko] undefined! ERROR: "pm_clk_suspend" [drivers/dma/tegra210-adma.ko] undefined! ERROR: "pm_clk_resume" [drivers/dma/tegra210-adma.ko] undefined! These were added as exports in the v4.8-rc1 merge window.
