(Baytrail tablet) From: Bastien Nocera To: linux-wireless@vger.kernel.org Date: Fri, 05 Sep 2014 00:39:38 +0200 Content-Type: text/plain; charset="UTF-8" Mime-Version: 1.0 Sender: linux-wireless-owner@vger.kernel.org List-ID: Heya, On this tablet, based on a Baytrail SoC, I found reference of this Broadcom device in the DSDT, and I believe it could be the Bluetooth/Wi-Fi chipset (this one[1]?): ---8<--- Device (BRC3) { Name (_ADR, One) // _ADR: Address Name (_DEP, Package (0x01) // _DEP: Dependencies { GPO2 }) Name (_HID, "BCM4321") // _HID: Hardware ID Name (_CID, "BCM43241") // _CID: Compatible ID Name (GMOD, ResourceTemplate () { GpioIo (Exclusive, PullDefault, 0x0000, 0x0000, IoRestrictionOutputOnly, "\\_SB.GPO2", 0x00, ResourceConsumer, , ) { // Pin list 0x0014 } }) ---8<--- Am I correct in thinking that it's a Broadcom chipset? What would it take to get this supported in the kernel? I'm currently stuck on a slightly older kernel (3.16.0) due to Intel graphics driver problems, but I couldn't find anything directly related to this in the current linus tree.
