I took my local branch based on next-20131014, and applied the following: * Joseph's "ARM: tegra: add clock properties for devices of Tegra124". * The patches from your "pull request for tegra clocks" of today (I just cherry-picked the commits rather than merging the pull request). * Your patch series "Introduce common infra for tegra clocks" of today. * Your patch series "Tegra124 clock support" of today. The resultant branch is at: git://github.com:swarren/linux-tegra.git linux-next_common When building, I see a number of section mismatches: > WARNING: drivers/clk/tegra/built-in.o(.text+0x534): Section mismatch in reference from the function _tegra_clk_register_periph() to the function .init.text:get_reg_bank() > The function _tegra_clk_register_periph() references > the function __init get_reg_bank(). > This is often because _tegra_clk_register_periph lacks a __init > annotation or the annotation of get_reg_bank is wrong. > > WARNING: drivers/clk/tegra/built-in.o(.text+0x9ec): Section mismatch in reference from the function tegra_clk_register_periph_gate() to the function .init.text:get_reg_bank() > The function tegra_clk_register_periph_gate() references > the function __init get_reg_bank(). > This is often because tegra_clk_register_periph_gate lacks a __init > annotation or the annotation of get_reg_bank is wrong. There are more, but they refer to references from the same two functions. You may need to add CONFIG_DEBUG_SECTION_MISMATCH=y to .config to see these; I can't remember if that's included in tegra_defconfig. Testing on Venice2 (Tegra124): I see the following WARN during boot, which I think is new relative to the internal branch you gave me yesterday: > [ 0.295386] ------------[ cut here ]------------ > [
