From 3ed16793e0e77ee9934611ac574468d1c984c3d8 Mon Sep 17 00:00:00 2001 From: Paul Gortmaker Date: Sat, 22 Oct 2016 18:25:10 -0400 Subject: dmaengine: tegra210-adma: convert TEGRA210_ADMA from bool to tristate 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.
