Discussed internally. This workaround will be tracked with open github issue qualcomm-linux/kernel#150 for formal closure. Recommend to prefix subject line with 'WORKAROUND:' tag that will help to clearly indicate the intent. Thanks. |
…bypass pwrseq flow There is a conflict between the current DTS configuration and the driver behavior for the WCN6855 Bluetooth path. With the PMU node in place, the driver takes the pwrseq code path unintentionally, which leads to Bluetooth failing to power up during an on -> off -> on transition. To unblock function, temporarily remove the WCN6855 PMU node so that the driver follows the non-pwrseq path and avoids the unexpected sequence. This is a TEMPORARY WORKAROUND. Once a proper M.2 binding/solution is upstreamed, will re-submit both DTS and driver changes aligned with the M.2 model. Signed-off-by: Wei Deng <wei.deng@oss.qualcomm.com>
