After commit f1ad5338a4d5 ("of: Fix "dma-ranges" handling for bus
controllers"), the dma-ranges property is not allowed for
the leaf node. But our iommu/dma-ranges is 16GB, we still expect
separate the 16GB dma-range like:
a) display is in 0 - 4GB;
b) vcodec is in 4GB - 8GB;
c) camera is in 8GB - 12GB.
We can not expect all the masters add a parent node for them,
especial for the existed drivers/nodes.
Thus, we add whole the 16GB dma-ranges in the parent "soc" node.

Similarly to what can be seen in MT8192, on MT8195 the mfg_core_tmp
clock is a mux used to switch between different "safe" (and slower)
clock sources for the GPU: this is used during MFGPLL reconfiguration
and eventually during idling at very low frequencies.
This clock getting turned off means that the GPU will occasionally be
unclocked, producing obvious consequences such as system crash or
unpredictable behavior: assigning it to the top level MFG power domain
will make sure that this stays on at all times during any operation on
the MFG domain (only GPU-related transactions).

order to ensure GPU stable operation.
While at it, also add voltage constraint overrides for the GPU SRAM

The MT8192 SoC specifies a maximum voltage for the GPU's digital supply
of 0.88V and the GPU OPPs are declaring a maximum voltage of 0.80V.
In order to keep the GPU voltage in the safe range, change the maximum
voltage for mt6315@7's vbuck1 to 0.80V as sending, for any mistake,
1.193V would be catastrophic.

reconfiguration and eventually during idling at very low frequencies.
This clock getting turned off means that the GPU will occasionally be
unclocked, producing obvious consequences such as system crash or
unpredictable behavior: assigning it to the top level MFG power domain
will make sure that this stays on at all times during any operation on
the MFG domain (only GPU-related transactions).

The MediaTek MT8192 includes a Mali-G57 GPU supported in Panfrost. Add
the GPU node to the device tree to enable 3D acceleration.
The GPU node is disabled by default. It should be enabled by board with
its power supplies correctly assigned.

Add coupling for these regulators, as they have a strict voltage output
relation to satisfy in order to ensure GPU stable operation.

This was done to keep a strict relation between VSRAM and VGPU, but
it never worked: now we're doing it transparently with the new
mediatek-regulator-coupler driver.
