msm8916.dtsi sets the iris compatible to "qcom,wcn3620". While WCN3620 seems to be used on most MSM8916 devices, MSM8916 can also be paired with another chip (e.g. for WiFi dual-band). A5U uses WCN3660B instead, so the compatible needs to be overridden to apply the correct configuration. However, simply using "qcom,wcn3660" would be incorrect, since WCN3660B requires a slightly different regulator configuration compared to WCN3660. Instead, it requires the same configuration as "qcom,wcn3680". Replace the compatible with "qcom,wcn3680" for A5U to make WCNSS work correctly. Signed-off-by: Stephan Gerhold <stephan@xxxxxxxxxxx> --- I'm not quite sure if it would be better to define a new compatible for WCN3660B (e.g. "qcom,wcn3660b") since this isn't really a WCN3680. But in any case, it would use exactly the same configuration. The compatible seems to be only used for regulator + clock configuration, see https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/remoteproc/qcom_wcnss_iris.c#n57 arch/arm64/boot/dts/qcom/msm8916-samsung-a5u-eur.dts | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/arch/arm64/boot/dts/qcom/msm8916-samsung-a5u-eur.dts b/arch/arm64/boot/dts/qcom/msm8916-samsung-a5u-eur.dts index 1aa59da98495..6629a621139c 100644 --- a/arch/arm64/boot/dts/qcom/msm8916-samsung-a5u-eur.dts +++ b/arch/arm64/boot/dts/qcom/msm8916-samsung-a5u-eur.dts @@ -8,3 +8,9 @@ model = "Samsung Galaxy A5U (EUR)"; compatible = "samsung,a5u-eur", "qcom,msm8916"; }; + +&pronto { + iris { + compatible = "qcom,wcn3680"; + }; +}; -- 2.22.1
