Le sam. 7 nov. 2020 à 19:52, 周琰杰 (Zhou Yanjie) <zhouyanjie@xxxxxxxxxxxxxx> a écrit :

1.Add OTG/OTG PHY/RNG nodes for JZ4780, CGU/OTG nodes for CI20.
2.Add OTG/OTG PHY/RNG/OST nodes for X1000, SSI/CGU/OST/OTG/SC16IS752
nodes for CU1000-Neo.
3.Add OTG/OTG PHY/DTRNG/OST nodes for X1830, SSI/CGU/OST/OTG/SC16IS752
nodes for CU1830-Neo.
