ARM: orion: remove unused board files

2023-01-10T22:10:27+00:00

As planned earlier, all board support that was marked unused can be removed now after nobody explicitly asked for these to be kept. In particular, all of the reference designs get removed now, as these are not commonly used productively any more. Also, the machines that were not supported by Debian or the Debian_on_Buffalo group because of limitations with RAM size are gone.

ARM: orion5x: Include platform_data/dsa.h

2019-01-17T19:31:24+00:00

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 Signed-off-by: David S. Miller

ARM: orion: Register DSA switch as a MDIO device

2017-02-07T15:51:47+00:00

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().

ARM: orion: simplify orion_ge00_switch_init

2016-09-14T14:36:13+00:00

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.

ARM: orion5x: clean up mach/*.h headers

2015-12-07T17:17:48+00:00

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.

ARM: orion: use SPARSE_IRQ everywhere

2015-12-07T17:17:07+00:00

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.

ARM: orion5x: Move to ID based window creation

2013-08-06T14:10:13+00:00

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.

arm: mach-orion5x: convert to use mvebu-mbus driver

2013-04-15T14:06:34+00:00

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.

ARM: delete struct sys_timer

2012-12-24T16:36:38+00:00

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.
