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.
