Hello,

This series adds the Mali GPU to Realtek RTD1195 and RTD1295 SoC DTs.

DT patches depend on RTD1295 clk series, to be resent; RTD1195 clk to be sent.
RTD1395 and RTD1619 DTs have not yet been prepared, only bindings while at it.

My testing was unsuccessful so far...

For RTD1195 I don't have a mali-supply yet, the bus clk was picked randomly
to make binding/driver happy, and the address/size is not clear.
For RTD1295 I don't have a bus clk specified; later patches add mali-supply
as G2227 PMIC's DCDC3 for Zidoo X9S.

RTD1295:
