Yes. Trats2 (exynos4412-based) has such a setup. The BCM4334 works fine with this patch and one more that enables the WL_REG_EN pin when brcmfmac is probed. Without this patch (and only enabling WL_REG_EN), the chip is detected but attempting to initialise it fails with a bunch of timeouts. > Regards, > Arend Cheers, Simon
