------------------ From: Marek Szyprowski <[email protected]> commit 5b23fceec1ff94305c5d1accde018cae27448005 upstream. FIMC LITE SYSMMU devices are defined in exynos5250.dtsi, but clocks for them are not instantiated by Exynos5250 clock provider driver. Add needed definitions for those clocks to fix IOMMU probe failure: ERROR: could not get clock /soc/sysmmu@13c40000:sysmmu(0) exynos-sysmmu 13c40000.sysmmu: Failed to get device clock(s)! exynos-sysmmu: probe of 13c40000.sysmmu failed with error -38 ERROR: could not get clock /soc/sysmmu@13c50000:sysmmu(0) exynos-sysmmu 13c50000.sysmmu: Failed to get device clock(s)! exynos-sysmmu: probe of 13c50000.sysmmu failed with error -38 Signed-off-by: Marek Szyprowski <[email protected]> Fixes: bfed1074f213 ("clk: exynos5250: Add missing sysmmu clocks for DISP and ISP blocks") Acked-by: Chanwoo Choi <[email protected]> Signed-off-by: Sylwester Nawrocki <[email protected]> Signed-off-by: Sudip Mukherjee <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]> --- drivers/clk/samsung/clk-exynos5250.c | 6 ++++++ 1 file changed, 6 insertions(+) --- a/drivers/clk/samsung/clk-exynos5250.c +++ b/drivers/clk/samsung/clk-exynos5250.c @@ -560,6 +560,8 @@ static const struct samsung_gate_clock e 0), GATE(CLK_GSCL3, "gscl3", "mout_aclk266_gscl_sub", GATE_IP_GSCL, 3, 0, 0), + GATE(CLK_CAMIF_TOP, "camif_top", "mout_aclk266_gscl_sub", + GATE_IP_GSCL, 4, 0, 0), GATE(CLK_GSCL_WA, "gscl_wa", "div_gscl_wa", GATE_IP_GSCL, 5, 0, 0), GATE(CLK_GSCL_WB, "gscl_wb", "div_gscl_wb", GATE_IP_GSCL, 6, 0, 0), GATE(CLK_SMMU_GSCL0, "smmu_gscl0", "mout_aclk266_gscl_sub", @@ -570,6 +572,10 @@ static const struct samsung_gate_clock e GATE_IP_GSCL, 9, 0, 0), GATE(CLK_SMMU_GSCL3, "smmu_gscl3", "mout_aclk266_gscl_sub", GATE_IP_GSCL, 10, 0, 0), + GATE(CLK_SMMU_FIMC_LITE0, "smmu_fimc_lite0", "mout_aclk266_gscl_sub", + GATE_IP_GSCL, 11, 0, 0), + GATE(CLK_SMMU_FIMC_LITE1, "smmu_fimc_lite1", "mout_aclk266_gscl_sub", + GATE_IP_GSCL, 12, 0, 0), GATE(CLK_FIMD1, "fimd1", "mout_aclk200_disp1_sub", GATE_IP_DISP1, 0, 0, 0),
