Add rk3568 based Bananapi R2 Pro board.
Signed-off-by: Frank Wunderlich frank-w@public-files.de
because iodomain is different to evb and now iodomain driver is sent as patch we need to separate between EVB and R2Pro else board can be bricked.
What's the detail difference before and after the iodomain driver for this board?
Sorry, missed this question somehow.
Evb defines these iodomains
&pmu_io_domains { pmuio1-supply = <&vcc3v3_pmu>; pmuio2-supply = <&vcc3v3_pmu>; vccio1-supply = <&vccio_acodec>; vccio2-supply = <&vcc_1v8>; vccio3-supply = <&vccio_sd>; vccio4-supply = <&vcc_1v8>; vccio5-supply = <&vcc_3v3>; vccio6-supply = <&vcc_1v8>; vccio7-supply = <&vcc_3v3>; status = "okay"; };
So vccio2 and vccio4 are 1v8 too which will brick these 2 io if still using this dts on r2pro which has these 2 3v3 (default).
