The real issue was hidden in the spi bus as reported in the following patch: https://lkml.org/lkml/2016/7/7/81 This patch in principle replaces the clock_ignore_unused flags in for the spi and enables the spi3 that in the tm2(e) board will be connected to the IR remote controller. Changelog: V1 -> V2 - the "sclk_spi3" doesn't need to be enabled in boot time as it is handled by the spi driver itself. - use the CLK_IS_CRITICAL flag for the ioclk V2 -> V3 - some more tests has confirmed taht "sclk_spi1,3" need to be enabled as critical! - added Chanwoo's review in the second commit. V3 -> V4 - patch V3 was wrong, back to patch v2. - reworded the commit of patch no. 1 Thanks, Andi Andi Shyti (2): clk: exynos5433: do not use CLK_IGNORE_UNUSED for SPI clocks clk: exynos5433: enable sclk_ioclk for SPI3 drivers/clk/samsung/clk-exynos5433.c | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) -- 2.8.1
