[PATCH] ARM: dts: sun8i-h3: Fix wifi in Beelink X2 DT

[PATCH] ARM: dts: sun8i-h3: Fix wifi in Beelink X2 DT

[Jernej Skrabec]

mmc1 node where wifi module is connected doesn't have properly defined
power supplies so wifi module is never powered up. Fix that by
specifying additional power supplies.

Additionally, this STB may have either Realtek or Broadcom based wifi
module. One based on Broadcom module also needs external clock to work
properly. Fix that by adding clock property to wifi_pwrseq node.

pinctrl-names only make sense with another pinctrl-[0-255]
property. Did you forgot something here?

No, I just took BananaPi M2+ as a example, which has pinctrl-names property 
too and no "pinctrl-*". But digging through history of this DT, it seems that 
this is just leftover which somebody forgot to remove.

I'll send v2.

Best regards,
Jernej

This should be fixed in 5.2 thanks to the commit 75f9a058838b
