LIN1021-4131 : octeon-tx2 spi warning ignoring unsupported mode bits a00

Created: Aug 9, 2022 Updated: Nov 22, 2022

Resolved Date: Oct 17, 2022

Found In Version: 10.21.20.13

Fix Version: 10.21.20.14

Severity: Standard

Applicable for: Wind River Linux LTS 21

Component/s: BSP

Description

On an octeon-tx2 board (CN96XX), we get the following warning:

spi spi0.0: setup: ignoring unsupported mode bits a00

This is not a limitation of the hardware but of the driver.

In commit 3db5ffbecee7b769aa762a1a9cd82aee7cc18fe0, SPI bus speed is limited to x1 in order to fix an error.

This is not a suitable solution since it does not properly reflect the hardware's capabilities.

Steps to Reproduce

Build and boot up a project with the marvell-cn96xx BSP, wrlinux-image-std and no other changes.
