Hi all,
Working with custom boards based on imx6q/imx6dl processors and 3.14.57 freescale BSP based kernel I have seen the following message in the dmesg of Dual Lite processors at boot:
galcore: clk_get vg clock failed, disable vg!
Quad/Dual dtsi file
gpu: gpu@00130000 {
- - -
clocks = <&clks IMX6QDL_CLK_GPU2D_AXI>, <&clks IMX6QDL_CLK_OPENVG_AXI>,
<&clks IMX6QDL_CLK_GPU3D_AXI>, <&clks IMX6QDL_CLK_GPU2D_CORE>,
<&clks IMX6QDL_CLK_GPU3D_CORE>, <&clks IMX6QDL_CLK_GPU3D_SHADER>;
clock-names = "gpu2d_axi_clk", "openvg_axi_clk",
"gpu3d_axi_clk", "gpu2d_clk",
"gpu3d_clk", "gpu3d_shader_clk";
- - -
};
Dual Lite dtsi file
gpu: gpu@00130000 {
- - -
clocks = <&clks IMX6QDL_CLK_OPENVG_AXI>, <&clks IMX6QDL_CLK_GPU3D_AXI>,
<&clks IMX6QDL_CLK_GPU2D_CORE>, <&clks IMX6QDL_CLK_GPU3D_CORE>,
<&clks IMX6QDL_CLK_DUMMY>;
clock-names = "gpu2d_axi_clk", "gpu3d_axi_clk",
"gpu2d_clk", "gpu3d_clk",
"gpu3d_shader_clk";
- - -
};
Looking at these dtsi files I have some questions:
- "openvg_axi_clk" is not defined in the Dual Lite file, is there any reason for it?
- "IMX6QDL_CLK_GPU2D_AXI" is not defined in the Dual Lite file, but the name is defined and matches a different clock, the "IMXQDL_CLK_OPENVG_AXI", which does not match with the definition in the Quad/Dual file.
- "gpu3d_shader_clk" matches two different clocks "IMX6QDL_CLK_GPU3D_SHADER" and "IMX6QDL_CLK_DUMMY". Why does the "gpu3d_shader_clk" have a dummy clock in the Dual Lite file?
Best regards.
Victor
