[PATCH 1/2] arm64: dts: renesas: r9a09g047e57-smarc: Drop SW_SER0_PMOD condition for rsci4

From: Biju

Date: Wed Jun 03 2026 - 10:55:27 EST


From: Biju Das <biju.das.jz@xxxxxxxxxxxxxx>

rsci4 is routed to either the PMOD connector or the M.2 connector
depending on the SW_SER0_PMOD switch state. In both cases, rsci4 is
available for use, so there is no need to guard it with SW_SER0_PMOD.

Drop the SW_SER0_PMOD condition and retain only the SW_LCD_EN check,
as rsci4 is unavailable only when the LCD is enabled.
