bcma: add ext PA workaround for BCM4331 and BCM43431

2012-06-17T18:21:26Z

commit 69aaedd3cfd23b2c732e3cf1227370a35f5c89d4 upstream. MacBook Pro models with BCM4331 wireless have been found to have the ext PA lines disabled after resuming from S3 without external power attach. This causes them to be unable to transmit. Add a workaround to ensure that the ext PA lines are enabled on BCM4331. Also extend all handling of ext PA line muxing to BCM43431 as is done in the Broadcom SDK.

bcma: use fallback sprom if no on chip sprom is available

2012-04-16T17:32:01Z

bcma should check for a fallback sprom every time it can not find a sprom on the card itself or a normal external sprom mapped into the memory of the chip. When otp sprom support was introduced it tried to read out the sprom from the wireless chip also if no otp sprom was available. This caused a Data bus error in bcma_sprom_get() when reading out the sprom for the SoC. This fixes a regression introduced in commit: commit 10d8493cd9efd38b1947b7a74276dbdc8311aa1a Author: Arend van Spriel Date: Tue Mar 6 15:50:48 2012 +0100 bcma: add support for on-chip OTP memory used for SPROM storage This patch was tested on a Netgear WNDR3400 (Broadcom BCM4718 SoC).

bcma: fix build error on MIPS; implicit pcibios_enable_device

2012-04-10T18:13:30Z

The following is seen during allmodconfig builds for MIPS: drivers/bcma/driver_pci_host.c:518:2: error: implicit declaration of function 'pcibios_enable_device' [-Werror=implicit-function-declaration] cc1: some warnings being treated as errors make[3]: *** [drivers/bcma/driver_pci_host.o] Error 1 Most likey introduced by commit 49dc9577155576b10ff79f0c1486c816b01f58bf "bcma: add PCIe host controller" Add the header instead of implicitly assuming it will be present. Sounds like a good idea, but that alone doesn't fix anything. The real problem is that the Kconfig has settings related to whether PCI is possible, i.e. config BCMA_HOST_PCI_POSSIBLE bool depends on BCMA && PCI = y default y config BCMA_HOST_PCI bool "Support for BCMA on PCI-host bus" depends on BCMA_HOST_PCI_POSSIBLE ...but what is missing is that BCMA_DRIVER_PCI_HOSTMODE doesn't have any dependencies on the above. Add one. CC: Hauke Mehrtens CC: John W. Linville Signed-off-by: Paul Gortmaker Acked-by: Hauke Mehrtens Signed-off-by: John W. Linville

bcma: add support for on-chip OTP memory used for SPROM storage

2012-03-06T20:16:18Z

Wireless Broadcom chips can have either their SPROM data stored on either external SPROM or on-chip OTP memory. Both are accessed through the same register space. This patch adds support for the on-chip OTP memory. Tested with: BCM43224 OTP and SPROM BCM4331 SPROM BCM4313 OTP This patch is in response to linux-wireless thread [1].

bcma: return error in bcma_sprom_get() when fallback fails

2012-03-06T20:16:18Z

When not SPROM is available a fallback mechanism is used. However, when that fails the code currently continues. This patch assures that the bcma_sprom_get() function aborts when that happens. Cc: Rafal Milecki Cc: Hauke Mehrtens Signed-off-by: Arend van Spriel Signed-off-by: John W. Linville

bcma: add support for sprom not found on the device

2012-03-05T20:20:50Z

On SoCs the sprom is stored in the nvram in a special partition on the flash chip. The nvram contains the sprom for the main bus, but sometimes also for a pci devices using bcma. This patch makes it possible for the arch code to register a function to fetch the needed sprom from the nvram and provide it to the bcma code. Signed-off-by: Hauke Mehrtens Signed-off-by: John W.
