[PATCH 0/8] brcmfmac: device support and some fixes

[Arend van Spriel]

This series adds support for the BCM43430 SDIO chipset. Recent
BCM4345 support is changed to support BCM43455 and BCM43457 as
it has been verified on those. In SDIO driver part memory barriers
have been added to assure data validity between driver threads.

This series is intended for v4.1 kernel and applies to the master
branch of the wireless-drivers-next repository.

Arend van Spriel (5):
  brcmfmac: avoid runtime-pm for sdio host controller
  brcmfmac: add MODULE_FIRMWARE() macros for bcm4356 PCIe device
  brcmfmac: add support for BCM43430 SDIO chipset
  brcmfmac: only support the BCM43455/7 device
  brcmfmac: remove support for unreleased BCM4354 PCIe

Hante Meuleman (3):
  brcmfmac: Add necessary memory barriers for SDIO.
  brcmfmac: Update msgbuf commonring size for improved throughput.
  brcmfmac: Remove unnecessary new-line in pcie console logging.

[PATCH 1/8] brcmfmac: avoid runtime-pm for sdio host controller

[Arend van Spriel]

Several host controllers supporting runtime-pm are causing issues
with our sdio wireless cards because they disable the sdio interrupt
upon going into runtime suspend. This patch avoids that by doing
a pm_runtime_forbid() call during the probe. Tested with Sony Vaio
Duo 13 which uses sdhci-acpi host controller.

[PATCH 2/8] brcmfmac: Add necessary memory barriers for SDIO.

[Arend van Spriel]

From: Hante Meuleman <meuleman@broadcom.com>

SDIO uses a thread to handle all communication with the device,
for this data is exchanged between threads. This data needs proper
memory barriers to make sure that data "exchange" is going correct.

[PATCH 7/8] brcmfmac: only support the BCM43455/7 device

[Arend van Spriel]

Recently support was added for the BCM4345 SDIO chipset by
commit 9c51026509d7 ("brcmfmac: Add support for BCM4345 SDIO chipset")
however this was verified using a BCM43455 device, which is
a more recent revision of the chip. This patch assure that
older revisions are not probed as they would fail.
