+Most of clocks and their parents are defined in contiguous range,
+But in few cases, there is gap in clock numbers[0].
+Driver assumes clocks to be in contiguous range, and add their clock
+ids incrementally.
+
+New firmware started returning error while calling get_freq and is_on
+API for non-available clock ids.
+
+In this fix, driver checks and adds only valid clock ids.

+Texas Instuments SK-AM62A Test and Development Board
+
+Description
+===========
+
+This configuration will build a complete image for the TI SK-AM62A
+board: https://www.ti.com/tool/SK-AM62A-LP
+
+How to Build
+============
+
+Select the default configuration for the target:
+
+$ make ti_am62ax_sk_defconfig
+
+Optional: modify the configuration:
+
+$ make menuconfig
+
+IMPORTANT: make sure to use the tiboot3 firmware that match with the TI
+K3 SoC boot ROM (tiboot3-am62ax-{gp/hs-fs/hs}-evm.bin) used on the board.
+Use the BR2_TARGET_TI_K3_R5_LOADER_TIBOOT3_BIN to name which tiboot3.bin
+security variant we want to use.
+
+Build:
+
+$ make
+
+To copy the resultimg output image file to an SD card use dd:
+
+$ dd if=output/images/sdcard.img of=/dev/sdX bs=1M
+
+How to Run
+==========
+
+Insert the SD card into the SK-AM62A board, and power it up through the
+USB Type-C connector. The system should come up. You can use a
+micro-USB cable to connect to the connector labeled UART to
+communicate with the board.
