2015-04-21arm(64): Manually clean up the mess left by write32() transitionJulius Werner
This patch is a manual cleanup of all the rubble left by coccinelle waltzing through our code base. It's generally not very good with line breaks and sometimes even eats comments, so this patch is my best attempt at putting it all back together. Also finally remove those hated writel()-style macros from the headers.

2015-03-27tegra132: Fix clock apisFurquan Shaikh
Instead of directly using the clk_src_id based on enum for clock source, every device needs to have its own set of clk source ids defined. This prevents accidentally selecting a wrong clk source if the ids are different from host1x's. Also, clk_src_id is separated from clk_src_freq_id. clk_src_id is the clk src id represented in CLK_SOURCE_<dev> registers, whereas clk_src_freq_id is used for handling the common clock sources based on id to get the proper frequency in software.
