net: ethernet: ixp4xx: Use parent dev for DMA pool

2020-01-12T20:59:53+00:00

Use the netdevice struct device .parent field when calling dma_pool_create(): the .dma_coherent_mask and .dma_mask pertains to the bus device on the hardware (platform) bus in this case, not the struct device inside the network device. This makes the pool allocation work. Signed-off-by: Linus Walleij Signed-off-by: Jakub Kicinski

ARM/net: ixp4xx: Pass ethernet physical base as resource

2020-01-12T20:59:53+00:00

In order to probe this ethernet interface from the device tree all physical MMIO regions must be passed as resources. Begin this rewrite by first passing the port base address as a resource for all platforms using this driver, remap it in the driver and avoid using any reference of the statically mapped virtual address in the driver.

net: ehernet: ixp4xx: Use netdev_* messages

2020-01-12T20:59:53+00:00

Simplify and correct a bunch of messages using printk directly to use the netdev_* macros. I have not changed all of them, just the low-hanging fruit. Signed-off-by: Linus Walleij Signed-off-by: Jakub Kicinski

net: ethernet: ixp4xx: Use distinct local variable

2020-01-12T20:59:53+00:00

Use "ndev" for the struct net_device and "dev" for the struct device in probe() and remove(). Add the local "dev" pointer for later use in refactoring. Take this opportunity to fix inverse christmas tree coding style. Signed-off-by: Linus Walleij Signed-off-by: Jakub Kicinski

net: ethernet: ixp4xx: Standard module init

2020-01-12T20:59:53+00:00

The IXP4xx driver was initializing the MDIO bus before even probing, in the callbacks supposed to be used for setting up the module itself, and with the side effect of trying to register the MDIO bus as soon as this module was loaded or compiled into the kernel whether the device was discovered or not. This does not work with multiplatform environments. To get rid of this: set up the MDIO bus from the probe() callback and remove it in the remove() callback. Rename the probe() and remove() calls to reflect the most common conventions. Since there is a bit of checking for the ethernet feature to be present in the MDIO registering function, making the whole module not even be registered if we can't find an MDIO bus, we need something similar: register the MDIO bus when the corresponding ethernet is probed, and return -EPROBE_DEFER on the other interfaces until this happens. If no MDIO bus is present on any of the registered interfaces we will eventually bail out. None of the platforms I've seen has e.g. MDIO on EthB and only uses EthC, there is always a Ethernet hardware on the NPE (B, C) that has the MDIO bus, we just might have to wait for it.

ixp4xx_eth: move platform_data definition

2020-01-12T20:59:53+00:00

The platform data is needed to compile the driver as standalone, so move it to a global location along with similar files. Signed-off-by: Arnd Bergmann Signed-off-by: Linus Walleij Signed-off-by: Jakub Kicinski

ptp: ixp46x: move adjacent to ethernet driver

2020-01-12T20:59:52+00:00

The ixp46x ptp driver has a somewhat unusual setup, where the ptp driver and the ethernet driver are in different directories but access the same registers that are defined a platform specific header file. Moving everything into drivers/net/ makes it look more like most other ptp drivers and allows compile-testing this driver on other targets.
