| Subject: ARM: dts: logicpd-torpedo-baseboard: Fix broken audio |
| |
| From: Adam Ford <aford173@gmail.com> |
| |
| [ Upstream commit d7dfee67688ac7f2dfd4c3bc70c053ee990c40b5 ] |
| |
| Older versions of U-Boot would pinmux the whole board, but as |
| the bootloader got updated, it started to only pinmux the pins |
| it needed, and expected Linux to configure what it needed. |
| |
| Unfortunately this caused an issue with the audio, because the |
| mcbsp2 pins were configured in the device tree, they were never |
| referenced by the driver. When U-Boot stopped muxing the audio |
| pins, the audio died. |
| |
| This patch adds the references to the associate the pin controller |
| with the mcbsp2 driver which makes audio operate again. |
| |
| Fixes: 739f85bba5ab ("ARM: dts: Move most of logicpd-torpedo-37xx-devkit to logicpd-torpedo-baseboard") |
