From c6c76445c30bb73fd4cfba8f4742e642dcfe90f5 Mon Sep 17 00:00:00 2001 From: Chris Morgan Date: Wed, 5 Nov 2025 14:57:08 -0600 Subject: [PATCH] arm64: dts: rockchip: Fix DMA for Indiedroid Nova Bluetooth When the device was first added, there was a problem with the bluetooth controller that manifested when DMA was enabled for the underlying UART interface. At some point in the intervening time the problem appears to have been resolved. Add the UART rx and tx channels back to re-enable UART.
