My main concern here is the AON clocks. If we don't model
gpu_cc_demet_clk as a leaf clock, then gpu_cc_demet_div_clk_src
becomes a clock without children and can be disabled by Linux.
Likewise not modelling gpu_cc_cxo_aon_clk removes one of the voters on
gpu_cc_xo_clk_src, which can now be turned off by Linux.
Our usual recommendation is to model such clocks properly and to use
CLK_IS_CRITICAL or CLK_IGNORE_UNUSED to mark then as aon.

Thanks for review, actually if leaf (branch) clock is ON, hardware will 
take care of enabling and keeping the parent ON. So parent clocks won't 
get turned OFF in HW as long as branch clock is enabled.

For clocks which are fixed rate (19.2MHz) and recommended to be kept ON 
forever from HW design, modelling and exposing clock structure in kernel 
will be a redundant code in kernel memory, hence as per earlier 
suggestion in previous thread such clocks are recommended to be kept 
enabled from probe.

Recommended by whom?

Kernel developers clearly recommend describing all the clocks so that
CCF has knowledge about all the clocks in the system.

Actually it's been recommended earlier by Stephen during initial 
discussion on moving such critical clocks to probe to avoid redundant 
codes in kernel memory. From then we're following similar approach in 
other mainlined CC's drivers for fixed rate clocks which needs to kept 
enabled always - eg: DISP_CC_XO_CLK (keeping bits enabled in probe) in 
SM8450, SM8650 etc.
