net: phy: fixed-phy: Drop GPIO from fixed_phy_add() All users of the fixed_phy_add() pass -1 as GPIO number to the fixed phy driver, and all users of fixed_phy_register() pass -1 as GPIO number as well, except for the device tree MDIO bus. Any new users should create a proper device and pass the GPIO as a descriptor associated with the device so delete the GPIO argument from the calls and drop the code looking requesting a GPIO in fixed_phy_add(). In fixed phy_register(), investigate the "fixed-link" node and pick the GPIO descriptor from "link-gpios" if this property exists. Move the corresponding code out of of_mdio.c as the fixed phy code anyways requires OF to be in use.

MIPS: BCM47XX: Setup struct device for the SoC So far we never had any device registered for the SoC. This resulted in some small issues that we kept ignoring like: 1) Not working GPIOLIB_IRQCHIP (gpiochip_irqchip_add_key() failing) 2) Lack of proper tree in the /sys/devices/ 3) mips_dma_alloc_coherent() silently handling empty coherent_dma_mask Kernel 4.19 came with a lot of DMA changes and caused a regression on bcm47xx. Starting with the commit f8c55dc6e828 ("MIPS: use generic dma noncoherent ops for simple noncoherent platforms") DMA coherent allocations just fail.

Revert "MIPS: BCM47XX: Enable 74K Core ExternalSync for PCIe erratum" This reverts commit 2a027b47dba6 ("MIPS: BCM47XX: Enable 74K Core ExternalSync for PCIe erratum"). Enabling ExternalSync caused a regression for BCM4718A1 (used e.g. in Netgear E3000 and ASUS RT-N16): it simply hangs during PCIe initialization. It's likely that BCM4717A1 is also affected. I didn't notice that earlier as the only BCM47XX devices with PCIe I own are: 1) BCM4706 with 2 x 14e4:4331 2) BCM4706 with 14e4:4360 and 14e4:4331 it appears that BCM4706 is unaffected. While BCM5300X-ES300-RDS.pdf seems to document that erratum and its workarounds (according to quotes provided by Tokunori) it seems not even Broadcom follows them. According to the provided info Broadcom should define CONF7_ES in their SDK's mipsinc.h and implement workaround in the si_mips_init(). Checking both didn't reveal such code. It *could* mean Broadcom also had some problems with the given workaround.

MIPS: BCM47XX: Enable 74K Core ExternalSync for PCIe erratum The erratum and workaround are described by BCM5300X-ES300-RDS.pdf as below. R10: PCIe Transactions Periodically Fail Description: The BCM5300X PCIe does not maintain transaction ordering. This may cause PCIe transaction failure. Fix Comment: Add a dummy PCIe configuration read after a PCIe configuration write to ensure PCIe configuration access ordering. Set ES bit of CP0 configu7 register to enable sync function so that the sync instruction is functional. Resolution: hndpci.c: extpci_write_config() hndmips.c: si_mips_init() mipsinc.h CONF7_ES This is fixed by the CFE MIPS bcmsi chipset driver also for BCM47XX. Also the dummy PCIe configuration read is already implemented in the Linux BCMA driver. Enable ExternalSync in Config7 when CONFIG_BCMA_DRIVER_PCI_HOSTMODE=y too so that the sync instruction is externalised.

MIPS: BCM47xx: Move SPROM driver to drivers/firmware/ Broadcom ARM home routers store SPROM content in NVRAM just like MIPS ones. To share SPROM code we need to move it out of arch/mips/ to some common place. We already have bcm47xx_nvram in firmware path and SPROM should fit there as well. This driver is responsible for parsing SoC configuration data into a struct shared between ssb and bcma buses. This was tested with BCM4706 & BCM5357C0 (BCM47XX) and BCM4708A0 (ARCH_BCM_5301X).

ssb: pick SoC invariants code from MIPS BCM47xx arch There is code in ssb fetching "invariants" that is basically a set of board specific data. Every host requires its own implementation of reading function. In ssb we have support for PCI, PCMCIA & SDIO. For some (historical?) reason code reading "invariants" for SoC was placed in arch code and provided by a callback. This is not needed nowadays, so lets move that into ssb. This way we keep all "invariants" functions in a single module making code cleaner. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

MIPS: BCM47XX: make reboot more relaiable The reboot on the BCM47XX SoCs is done, by setting the watchdog counter to 1 and let it trigger a reboot, when it reaches 0. Some devices with a BCM4705/BCM4785 SoC do not reboot when the counter is set to 1 and decreased to 0 by the hardware. It looks like it works more reliable when we set it to 3. As far as I understand the hardware, this should not make any difference, but I do not have access to any documentation for this SoC. It is still not 100% reliable.

MIPS: BCM47XX: only print SoC name in system type in cpuinfo Recently the output of "system type" in /proc/cpuinfo was changed to Broadcom BCM4730 (Some sample board), but it is better to just print the SoC name in the "system type" entry. The board name will be added in the machine entry later.

b44: use fixed PHY device if we do not find any The ADM6996L switch and some Broadcom switches with two MII interfaces like the BCM5325F connected to two MACs on the SoC, used on some routers do not return a valid value when reading the PHY id register and Linux thinks there is no PHY at all, but that is wrong. This patch registers a fixed phy in the arch code and then searches it when there is no other phy in the Ethernet driver code. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: David S.

MIPS: BCM47xx: sprom: read values without prefix as fallback 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.

bcma: Move initialization of SPROM to prevent overwrite The first thing bcm47xx_fill_sprom does is initialize (zero fill) the SPROM. For BCMA SOC, this wipes out any values previously read by bcm47xx_fill_sprom_ethernet (see arch/mips/bcm47xx/setup.c - bcm47xx_get_sprom_bcma). Move the initialization of SPROM so it is called prior to filling in any values. Signed-off-by: Nathan Hintz <nlhintz@hotmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

ssb: remove rev from boardinfo Previously the rev contained the revision read from the pci config space and was used as board_rev in the wireless drivers. This is wrong the board_rev is only fetched from the sprom accordingly to the open source part of the Broadcom SDK and brcmsmac. This patch removes the rev from the boardinfo structure and uses the board_rev attribute from sprom instead. This attribute is filled by PCI, PCMCIA, SDIO and SoC code.

MIPS: BCM47xx: Register SSB fallback sprom callback We are generating the prefix based on the PCI bus address the device is on. This is done like Broadcom does it in their code expect that the the bus number is increased by one. In the SB bus implementation used by Broadcom the SB bus emulates a PCI bus so the kernel sees one PCI bus more then in our implementation. We do not handle prefixes like sb/1/ yet as they are only used on the new bus which is not implemented yet.

MIPS: BCM47xx: Extend bcm47xx_fill_sprom with prefix. When an other SSB based device without an own SPROM is attached, using the PCI bus to the main SSB based device, the data normally found in the SPROM will be stored in the NVRAM on modern devices. The keys, to load the data from the NVRAM, are all using some sort of prefix like pci/1/1/, pci/1/3/ or sb/1/ before the actual key. This patch extends bcm47xx_fill_sprom() to make it possible to read out these values when some prefix was used. The keys for the SPROM data used on the main chip does not have a prefix.

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.
