2019-01-17ARM: orion5x: Include platform_data/dsa.hFlorian Fainelli
Now that we have split the DSA platform data structures from the main net/dsa.h header file, include only the relevant header file. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-02-07ARM: orion: Register DSA switch as a MDIO deviceFlorian Fainelli
Utilize the ability to pass board specific MDIO bus information towards a particular MDIO device thus allowing us to provide the per-port switch layout to the Marvell 88E6XXX switch driver. Since we would end-up with conflicting registration paths, do not register the "dsa" platform device anymore. Note that the MDIO devices registered by code in net/dsa/dsa2.c does not parse a dsa_platform_data, but directly take a dsa_chip_data (specific to a single switch chip), so we update the different call sites to pass this structure down to orion_ge00_switch_init().

2016-09-14ARM: orion: simplify orion_ge00_switch_initArnd Bergmann
One of the last users of NO_IRQ on ARM is the switch initialization code on orion5x, which sometimes passes a GPIO based IRQ number. However, the driver doesn't actually use this number, and according to Andrew Lunn never will do it for non-DT based machines, so we can simply drop the irq argument. Simplifying it further, we can also drop the static platform_device and instead call platform_device_register_data(), which in turn lets us mark the platform_data structures as __initdata and slightly reduce the memory consumption.

2015-12-07ARM: orion5x: clean up mach/*.h headersArnd Bergmann
This is a simple move of all header files that are no longer included by anything else from the include/mach directory to the platform directory itself as preparation for multiplatform support. The mach/uncompress.h headers are left in place for now, and are mildly modified to be independent of the other headers. They will be removed entirely when ARCH_MULTIPLATFORM gets enabled and they become obsolete. Rather than updating the path names inside of the comments of each header, I delete those comments to avoid having to update them again, should they get moved or copied another time.

2015-12-07ARM: orion: use SPARSE_IRQ everywhereArnd Bergmann
As a preparation for multiplatform support, this moves all the code using plat-orion over to use sparse irq support, which is enabled implicitly for multiplatform. In particular, the hardcoded NR_IRQS macro gets replaced with a machine specific one that is set in the machine descriptor in order to set up a static mapping for all legacy interrupts.

2013-08-06ARM: orion5x: Move to ID based window creationThomas Petazzoni
With the introduction of the ID based MBus API, it's better to switch to use it instead of the current name based scheme. This will allow to deprecate the name based API, once every user is removed.

2013-04-15arm: mach-orion5x: convert to use mvebu-mbus driverThomas Petazzoni
This commit migrates the mach-orion5x platforms to use the mvebu-mbus driver and therefore removes the Orion5x-specific addr-map code. The dove_init_early() function now initializes the mvebu-mbus driver by calling mvebu_mbus_init(). We also convert a number of orion5x_setup_xyz_win() calls to the appropriate mvebu_mbus_add_window() calls, as each board was doing its own setup for the NOR window or other devices. Ultimately, those devices will be probed from the DT. The common address decoding windows are now registered in the orion5x_setup_wins() function. It is worth noting that the four PCIe address decoding windows will ultimately no longer have to be registered here: it will be done automatically by the PCIe driver once Dove has been migrated to use the upcoming mvebu PCIe driver.

2012-12-24ARM: delete struct sys_timerStephen Warren
Now that the only field in struct sys_timer is .init, delete the struct, and replace the machine descriptor .timer field with the initialization function itself. This will enable moving timer drivers into drivers/clocksource without having to place a public prototype of each struct sys_timer object into include/linux; the intent is to create a single of_clocksource_init() function that determines which timer driver to initialize by scanning the device dtree, much like the proposed irqchip_init() at: http://www.spinics.net/lists/arm-kernel/msg203686.html Includes mach-omap2 fixes from Igor Grinberg.

2012-05-13ARM: PCI: get rid of pci_std_swizzle()Russell King
Most PCI implementations use the standard PCI swizzle function, which handles the well defined behaviour of PCI-to-PCI bridges which can be found on cards (eg, four port ethernet cards.) Rather than having almost every platform specify the standard swizzle function, make this the default when no swizzle function is supplied. Therefore, a swizzle function only needs to be provided when there is something exceptional which needs to be handled. This gets rid of the swizzle initializer from 47 files, and leaves us with just two platforms specifying a swizzle function: ARM Integrator and Chalice CATS.

2011-07-22PCI: Make the struct pci_dev * argument of pci_fixup_irqs const.Ralf Baechle
Aside of the usual motivation for constification, this function has a history of being abused a hook for interrupt and other fixups so I turned this function const ages ago in the MIPS code but it should be done treewide. Due to function pointer passing in varous places a few other functions had to be constified as well.

2009-03-21dsa: add switch chip cascading supportLennert Buytenhek
The initial version of the DSA driver only supported a single switch chip per network interface, while DSA-capable switch chips can be interconnected to form a tree of switch chips. This patch adds support for multiple switch chips on a network interface. An example topology for a 16-port device with an embedded CPU is as follows: +-----+ +--------+ +--------+ | |eth0 10| switch |9 10| switch | | CPU +----------+ +-------+ | | | | chip 0 | | chip 1 | +-----+ +---++---+ +---++---+ || || || || ||1000baseT ||1000baseT ||ports 1-8 ||ports 9-16 This requires a couple of interdependent changes in the DSA layer: - The dsa platform driver data needs to be extended: there is still only one netdevice per DSA driver instance (eth0 in the example above), but each of the switch chips in the tree needs its own mii_bus device pointer, MII management bus address, and port name array. (include/net/dsa.h) The existing in-tree dsa users need some small changes to deal with this. (arch/arm) - The DSA and Ethertype DSA tagging modules need to be extended to use the DSA device ID field on receive and demultiplex the packet accordingly, and fill in the DSA device ID field on transmit according to which switch chip the packet is heading to. (net/dsa/tag_{dsa,edsa}.c) - The concept of "CPU port", which is the switch chip port that the CPU is connected to (port 10 on switch chip 0 in the example), needs to be extended with the concept of "upstream port", which is the port on the switch chip that will bring us one hop closer to the CPU (port 10 for both switch chips in the example above). - The dsa platform data needs to specify which ports on which switch chips are links to other switch chips, so that we can enable DSA tagging mode on them. (For inter-switch links, we always use non-EtherType DSA tagging, since it has lower overhead. The CPU link uses dsa or edsa tagging depending on what the 'root' switch chip supports.) This is done by specifying "dsa" for the given port in the port array. - The dsa platform data needs to be extended with information on via which port to reach any given switch chip from any given switch chip. This info is specified via the per-switch chip data struct ->rtable[] array, which gives the nexthop ports for each of the other switches in the tree. For the example topology above, the dsa platform data would look something like this: static struct dsa_chip_data sw[2] = { { .mii_bus = &foo, .sw_addr = 1, .port_names[0] = "p1", .port_names[1] = "p2", .port_names[2] = "p3", .port_names[3] = "p4", .port_names[4] = "p5", .port_names[5] = "p6", .port_names[6] = "p7", .port_names[7] = "p8", .port_names[9] = "dsa", .port_names[10] = "cpu", .rtable = (s8 []){ -1, 9, }, }, { .mii_bus = &foo, .sw_addr = 2, .port_names[0] = "p9", .port_names[1] = "p10", .port_names[2] = "p11", .port_names[3] = "p12", .port_names[4] = "p13", .port_names[5] = "p14", .port_names[6] = "p15", .port_names[7] = "p16", .port_names[10] = "dsa", .rtable = (s8 []){ 10, -1, }, }, }, static struct dsa_platform_data pd = { .netdev = &foo, .nr_switches = 2, .sw = sw, }; Signed-off-by: Lennert Buytenhek <buytenh@marvell.com> Tested-by: Gary Thomas <gary@mlbassoc.com> Signed-off-by: David S.

2008-09-05mv643xx_eth: remove force_phy_addr fieldLennert Buytenhek
Currently, there are two different fields in the mv643xx_eth_platform_data struct that together describe the PHY address -- one field (phy_addr) has the address of the PHY, but if that address is zero, a second field (force_phy_addr) needs to be set to distinguish the actual address zero from a zero due to not having filled in the PHY address explicitly (which should mean 'use the default PHY address'). If we are a bit smarter about the encoding of the phy_addr field, we can avoid the need for a second field -- this patch does that. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com>

2008-07-24mv643xx_eth: use auto phy polling for configuring (R)(G)MII interfaceLennert Buytenhek
The mv643xx_eth hardware has a provision for polling the PHY's MII management registers to obtain the (R)(G)MII interface speed (10/100/1000) and duplex (half/full) and pause (off/symmetric) settings to use to talk to the PHY. The driver currently does not make use of this feature. Instead, whenever there is a link status change event, it reads the current link parameters from the PHY, and programs those parameters into the mv643xx_eth MAC by hand. This patch switches the mv643xx_eth driver to letting the MAC auto-determine the (R)(G)MII link parameters by PHY polling, if there is a PHY present. For PHYless ports (when e.g. the (R)(G)MII interface is connected to a hardware switch), we keep hardcoding the MII interface parameters. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com>
