From 1bea0512c3394965de28a152149b90afd686fae5 Mon Sep 17 00:00:00 2001 From: Rafał Miłecki Date: Mon, 11 Jul 2016 23:01:36 +0200 Subject: bcma: add PCI ID for Foxconn's BCM43142 device After discovering there are 2 very different 14e4:4365 PCI devices we made ID tables less generic. Back then we believed there are only 2 such devices: 1) 14e4:4365 1028:0016 with SoftMAC BCM43142 chipset 2) 14e4:4365 14e4:4365 with FullMAC BCM4366 chipset >From the recent report it appears there is also 14e4:4365 105b:e092 which should be claimed by bcma. Add back support for it.

ARM devices got a separated SPI controller and weere using standard SPI drivers. This has changed with the wireless SoC BCM47189B0. It's ARM based but has serial flash attached just like older devices. This allows using existing driver with these devices.
