Subject: [PATCH] arm64: dts: mt8183: Add node for the Mali GPU
Add a basic GPU node and opp table for mt8183.
The binding we use with out-of-tree Mali drivers includes more
clocks, I assume this would be required eventually if we have an
in-tree driver:
clocks =
<&topckgen CLK_TOP_MFGPLL_CK>,
<&topckgen CLK_TOP_MUX_MFG>,
<&clk26m>,
<&mfgcfg CLK_MFG_BG3D>;
clock-names =
"clk_main_parent",
"clk_mux",
"clk_sub_parent",
"subsys_mfg_cg";
Signed-off-by: Nicolas Boichat <drinkcat@...omium.org>

The evb part of this change depends on this patch to add PMIC dtsi:
