[PATCH v3] arm64: dts: ti: k3-j721s2: Correct pinmux offset for ospi

From: Udit Kumar
Date: Thu Aug 03 2023 - 10:57:48 EST


Due to non-addressable regions in J721S2 SOC wkup_pmx was split
into four regions from wkup_pmx0 to wkup_pmx3.

After split while updating the pin mux references to newly defined
four wkup_pmx, pin mux for OSPI0 was left.
Pin mux for OSPI0 is spread over two range wkup_pmx0
and wkup_pmx1, correcting pin mux for ospi and
adding correct pin mux setting within ospi node.

Also correcting OSPI1 pinmux which falls under wkup_pmx1
along with removing unused MCU_OSPI1_CSn1 pin for OSPI.

Fixes: 6bc829ceea41 ("arm64: dts: ti: k3-j721s2: Fix wkup pinmux range")
