The clock state update is the source of many problems, and capturing
this sort of information helps debug. This commit introduces tracepoints
for capturing clock values and also add traces in DCE, DCN1, DCN2x, and
DCN3.

Some hardware variants contain a system cache or the last level
cache(llc). This cache is typically a large block which is shared
by multiple clients on the SOC. GPU uses the system cache to cache
both the GPU data buffers(like textures) as well the SMMU pagetables.
This helps with improved render

Oh.. how did I miss drivers/media/dvb-core/dvb_vb2.c?
Should have grep-ed more.

Add display clock drivers required to get DSI and DP displays working on
SM8150 and SM8250 SoCs.
Derived from downstream drivers. Notable changes compared to downstream:
- EDP clks removed (nothing uses these even in downstream it seems)
- freq_tbl values for dp_link clk is in Hz and not kHz
v2
These two bindings are almost identical, so combine them into one. This
will make it easier to add the sm8150 and sm8250 dispcc bindings.

I would like to avoid triggering the "your system may be vunerable"
messages on fixed kernel, hence the separate test.
