The top half of UARTF on the HLK-RM04 is used for GPIO.
mode 1 mode 2
RIN GPIO14
DSR_N GPIO13
DCD_N GPIO12
DTR_N GPIO11
RXD GPIO10
CTS_N GPIO09
TXD GPIO08
RTS_N GPIO07
This patch applies 3'b101 mode to UARTF:
GPIO14
GPIO13
GPIO12
GPIO11
RXD
CTS_N
TXD
RTS_N
Because the base rt5350.dtsi file forces 3'b000 mode, remove the pin setting from this file and apply it directly to the files that inherit from it (WIZFI630A.dts and WT1520.dtsi). This change makes the rt5350.dtsi file consistent with the mt7620a.dtsi file.
