This patch adds the driver for the ETOP Packet Processing Engine (PPE32) found inside the XWAY family of Lantiq MIPS SoCs. This driver makes 100MBit ethernet work. Support for all 8 dma channels, gbit and the embedded switch found on the ar9/vr9 still needs to be implemented. Signed-off-by:

The Lantiq family of SoCs have a EBU (External Bus Unit). This patch adds the driver that allows us to use the EBU as a PCI controller. In order for PCI to work the EBU is set to endianess swap all the data. In addition we need to make use of SWAP_IO_SPACE for device->host DMA to work. The clock of the PCI works in several modes (internal/external). If this is not configured correctly the SoC will hang. Signed-off-by:

Add support for the Lantiq XWAY family of Mips24KEc SoCs. * Danube (PSB50702) * Twinpass (PSB4000) * AR9 (PSB50802) * Amazon SE (PSB5061) The Amazon SE is a lightweight SoC and has no PCI as well as a different clock. We split the code out into seperate files to handle this. The GPIO pins on the SoCs are multi function and there are several bits we can use to configure the pins. To be as compatible as possible to GPIOLIB we add a function int lq_gpio_request(unsigned int pin, unsigned int alt0, unsigned int alt1, unsigned int dir, const char *name); which lets you configure the 2 "alternate function" bits. This way drivers like PCI can make use of GPIOLIB without a cubersome wrapper. The PLL code inside arch/mips/lantiq/xway/clk-xway.c is voodoo to me. It was taken from a 2.4.20 source tree and was never really changed by me since then. Signed-off-by: -

Add initial support for Mips based SoCs made by Lantiq. This series will add support for the XWAY family. The series allows booting a minimal system using a initramfs or NOR. Missing drivers and support for Amazon and GPON family will be provided in a later series. [Ralf: Remove some cargo cult programming and fixed formatting.] Signed-off-by:

Grant Likely authored
Commit b826291c, "drivercore/dt: add a match table pointer to struct device" added an of_match pointer to struct device to cache the of_match_table entry discovered at driver match time. This was unsafe because matching is not an atomic operation with probing a driver. If two or more drivers are attempted to be matched to a driver at the same time, then the cached matching entry pointer could get overwritten. This patch reverts the of_match cache pointer and reworks all users to call of_match_device() directly instead. Signed-off-by:

If two drivers are probing devices at the same time, both will write their match table result to the dev->of_match cache at the same time. Only write the result if the device matches. In a thread titled "SBus devices sometimes detected, sometimes not", Meelis reported his SBus hme was not detected about 50% of the time. From the debug suggested by Grant it was obvious another driver matched some devices between the call to match the hme and the hme discovery failling. Reported-by:

configfs_readdir() will use the existing inode numbers of inodes in the dcache, but it makes them up for attribute files that aren't currently instantiated. There is a race where a closing attribute file can be tearing down at the same time as configfs_readdir() is trying to get its inode number. We want to get the inode number of open attribute files, because they should match while instantiated. We can't lock down the transition where dentry->d_inode is set to NULL, so we just check for NULL there. We can, however, ensure that an inode we find isn't iput() in configfs_d_iput() until after we've accessed it. Signed-off-by:Joel Becker <jlbec@evilplan.org>
