Unable to enable clock for HDMI TX in IMX8QM

[vinothkumars]

Hi,

I am working on HDMI TX for IMX8QM Custom variant with Android.

I got kernel crash because of following functionality from dts,

clk_gate2_scu_is_enabled:

clks[IMX8QM_HDMI_LIS_IPG_CLK] = imx_clk_gate2_scu("hdmi_lis_ipg_clk", "ipg_hdmi_clk_root", LPCG_ADDR(DI_HDMI_LPCG + 0x4), 16, FUNCTION_NAME(PD_HDMI));
