* MIPS: BCM47XX: Get GPIO pin from nvram configurationHauke Mehrtens2013-10-291-0/+2
| | | | | | | | | | | | | | | The nvram contains some gpio configuration for boards. It is stored in a gpio<number>=name format e.g. gpio8=wps_button gpio4=robo_reset This patches adds a function to parse these entries, so other driver can use it.

* MIPS: BCM47XX: Add board detectionHauke Mehrtens2013-10-291-0/+110
| | | | | | | | | | | | | | Detect on which board this code is running based on some nvram settings. This is needed to start board specific workarounds and configure the leds and buttons which are on different gpios on every board. This patches add some boards we have seen, but there are many more.

* MIPS: BCM47XX: add bcm47xx prefix in front of nvram function namesHauke Mehrtens2013-02-151-5/+5
| | | | | | | | | | The nvram functions are exported and used by some normal drivers. To prevent name clashes with ofter parts of the kernel code add a bcm47xx_ prefix in front of the function names and the header file name.

| * MIPS: BCM47xx: sprom: read values without prefix as fallbackHauke Mehrtens2012-11-091-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are bcma based devices like the Linksys E2000 out there, which do have one ieee80211 core, but no PCIe core and they are using no prefixes for the sprom. In addition some values like boardtype are stored without a prefix for the main SoC chip also when they have an additional PCIe wifi chip with an own boardtype var on some devices. The Ethernet addresses are now also read out correctly without a prefix so calling bcm47xx_fill_sprom_ethernet is not needed any more.

* MIPS: BCM47XX: move and extend sprom parsingHauke Mehrtens2012-03-051-0/+3
| | | | | | | | | | Move the sprom parsing from nvram into sprom.c. There are all values needed for sprom version 1 to 9 read from nvram and there are more sanity checks added. This is based on the sprom parsing in the open source part of the Broadcom SDK. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| | | | | | | | | | | | | | Since eb9ae7f2 (gpio: fix build error in include/asm-generic/gpio.h) the generic version of gpio.h calls __gpio_{set,get}_value which we do not define.

* bcm47xx: prepare to support different busesHauke Mehrtens2011-08-082-17/+52
| | | | | | | | | | | | Prepare bcm47xx to support different System buses. Before adding support for bcma it should be possible to build bcm47xx without the need of ssb. With this patch bcm47xx does not directly contain a ssb_bus, but a union contain all the supported system buses. As a SoC just uses one system bus a union is a good choice.

* MIPS: BCM47xx: Add NVRAM support devicesWaldemar Brodkorb2010-07-051-0/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When trying to netboot a Linksys WRT54GS WLAN router, the bootup fails, because of following error message: ... [ 0.424000] b44: b44.c:v2.0 [ 0.424000] b44: Invalid MAC address found in EEPROM [ 0.432000] b44 ssb0:1: Problem fetching invariants of chip,aborting [ 0.436000] b44: probe of ssb0:1 failed with error -22 ... The router uses a CFE bootloader, but most of the needed environment variables for network card initialization, are not available from CFE via printenv and even though not via cfe_getenv(). The required environment variables are saved in a special partition in flash memory. The attached patch implement nvram_getenv and enables bootup via NFS root on my router. Most of the patch is extracted from the OpenWrt subversion repository and stripped down and cleaned up to just fix this issue. [Ralf: sorted out header file inclusions. Lots of unneded headers and such that should have been included.] Signed-off-by: Waldemar Brodkorb <wbx@openadk.org> Reviewed-by: Phil Sutter <phil@nwl.cc> To: linux-mips@linux-mips.org Cc: Hauke Mehrtens <hauke@hauke-m.de> Patchwork: http://patchwork.linux-mips.org/patch/1359/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

| | | | | | | | | | | | The GPIO API is supposed to return 0 or a negative error code, but the SSB GPIO functions return the bitmask of the GPIO register. Fix this by ignoring the bitmask and always returning 0. The SSB GPIO functions can't fail.
