Subject: [PATCH v3 4/4] arm64: dts: ti: k3-j784s4-evm: Remove Pinmux for CTS and RTS in wkup_uart0
Date: Wed, 14 Feb 2024 16:28:46 +0530	[thread overview]
Message-ID: <20240214105846.1096733-5-b-kapoor@ti.com> (raw)
In-Reply-To: <20240214105846.1096733-1-b-kapoor@ti.com>

Only Tx and Rx Signal lines for wkup_uart0 are brought out on
the J784S4 EVM from SoC, but CTS and RTS signal lines are not
brought on the EVM. Thus, remove pinmux for CTS and RTS signal
lines for wkup_uart0 in J784S4.

Fixes: 6fa5d37a2f34 ("arm64: dts: ti: k3-j784s4-evm: Add mcu and wakeup uarts")
