| Subject: arm64: dts: qcom: msm8998-mtp: Add alias for blsp1_uart3 |
| |
| From: Bjorn Andersson <bjorn.andersson@linaro.org> |
| |
| commit c9ec155b5962233aff3df65210bd6a4788dee21c upstream. |
| |
| The msm_serial driver has a predefined set of uart ports defined, which |
| is allocated either by reading aliases or if no match is found a simple |
| counter, starting at index 0. But there's no logic in place to prevent |
| these two allocation mechanism from colliding. As a result either none |
| or all of the active msm_serial instances must be listed as aliases. |
| |
| Define blsp1_uart3 as "serial1" to mitigate this problem. |
| |
| Fixes: 4cffb9f2c700 ("arm64: dts: qcom: msm8998-mtp: Enable bluetooth") |
