It mistakenly referenced CLK_DOUT_CLUSTER0_PERIPHCLK, which corresponds to a cluster peripheral clock, not the last clock ID for CPUCL0 as intended. This patch corrects the definition to use CLK_DOUT_CPUCL0_NOCP + 1, properly matching the last clock ID for CPUCL0 as intended. This error was due to confusion with the hardware diagram, and this patch ensures that the number of clocks for CPUCL0 is correctly defined.

The VO sub-system manages clock gates for multimedia components including HDMI, MIPI, and GPU. Document the VIDEO_PLL requirements for the VO clock controller, which receives its input from the AP clock controller. The VIDEO_PLL is a Silicon Creations Sigma-Delta (integer) PLL typically running at 792 MHz with maximum FOUTVCO of 2376 MHz. This binding complements the existing AP sub-system clock controller which manages CPU, DPU, GMAC and TEE PLLs.

Up until now, the T-Head clock driver only supported AP clocks. Extend the driver to provide clock functionality for the VO subsystem. At this stage, the focus is on implementing the VO clock gates, as these are currently the most relevant and required components for enabling and disabling the VO subsystem functionality. Future enhancements may introduce additional VO-related clocks as necessary.

It shows 400Mhz instead of 40Mhz as below. dout_shared2_div4 1 1 0 400000000 0 0 50000 Y ... mout_hsi1_usbdrd_user 0 0 0 400000000 0 0 50000 Y ... dout_clkcmu_hsi1_usbdrd 0 0 0 40000000 0 0 50000 Y ... Correct the clk_tree by adding correct clock parent for "mout_hsi1_usbdrd_user". Post this change, clk_summary shows correct value. dout_shared2_div4 1 1 0 400000000 0 0 50000 Y ... mout_clkcmu_hsi1_usbdrd 0 0 0 400000000 0 0 50000 Y ... dout_clkcmu_hsi1_usbdrd 0 0 0 40000000 0 0 50000 Y ... mout_hsi1_usbdrd_user 0 0 0 40000000 0 0 50000 Y ...
