Thanks for submitting this patch.
I compare this with drivers/clk/mediatek/clk-mt7986-apmixed.c,
and other clk files are using macros to make the mtk_pll_data array
more readable.
Would you mind following the same style for all c files, please?
e.g.,
static const struct mtk_pll_data plls[] = {
PLL(CLK_APMIXED_ARMPLL, "armpll", 0x0200, 0x020C, 0x00000001, 0, 32,
0x0200, 4, 0, 0x0204, 0),
PLL(CLK_APMIXED_NET2PLL, "net2pll", 0x0210, 0x021C, 0x00000001, 0, 32,
0x0210, 4, 0, 0x0214, 0),
...
};

Would you mind changing all Mediatek to MediaTek?
i.e.,
s/Mediatek/MediaTek/
