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.
