ARM: orion/gpio: Get rid of unused first parameter in orion_gpio_init()

2022-02-03T08:25:11Z

The OF node pointer is always NULL, get rid of unused parameter in orion_gpio_init(). As a side effect it will allow to switch GPIO library to the fwnode API, as well as in case of resurrecting it here it should be fwnode_handle anyways.

ARM: orion: Register DSA switch as a MDIO device

2017-02-07T15:51:47Z

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

2016-09-14T14:36:13Z

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: mv78xx0: simplify ethernet device creation

2016-09-14T14:35:37Z

Out of the four ethernet devices on mv78xx0, only the first one has an error interrupt line, for the other ones we pass NO_IRQ and then ignore the argument. In order to get closer to complete remove of NO_IRQ, this simply drops the unused function arguments. Signed-off-by: Arnd Bergmann Reviewed-by: Andrew Lunn Signed-off-by: Gregory CLEMENT

ARM: orion: move watchdog setup to mach-orion5x

2015-12-07T17:09:32Z

The watchdog device node is created in plat-orion/common.c but depends on the bridge address that is platform specific, so as a preparation for orion multiplatform support, we move it out of the common code into orion5x and dove. At the moment, dove does not use the watchdog, so I'm marking the function as __maybe_unused for the moment. The compiler will be able to compile out the device definition this way, and we can easily add it later. Signed-off-by: Arnd Bergmann Acked-by: Andrew Lunn Signed-off-by: Gregory CLEMENT

leds: leds-gpio: Convert gpio_blink_set() to use GPIO descriptors

2014-11-04T20:58:25Z

Commit 21f2aae91e902aad ("leds: leds-gpio: Add support for GPIO descriptors") already converted most of the driver to use GPIO descriptors. What is still missing is the platform specific hook gpio_blink_set() and board files which pass legacy GPIO numbers to this driver in platform data. In this patch we handle the former and convert gpio_blink_set() to take GPIO descriptor instead. In order to do this we convert the existing four users to accept GPIO descriptor and translate it to legacy GPIO number in the platform code. This effectively "pushes" legacy GPIO number usage from the driver to platforms. Also add comment to the remaining block describing that it is legacy code path and we are getting rid of it eventually.

ARM: orion: remove no longer needed gpio DT code

2014-04-26T19:45:28Z

Following the move to pure DT-based probing of the GPIO controllers on Orion5x, some code in plat-orion/orion-gpio.c can be removed as it is no longer used.

Following the move of the Orion5x Device Tree support to use irqchip_init() for the interrupt controller probing, the plat-orion/irq.c code for DT-probing of the interrupt controller is no longer necessary, so we can get rid of it.

ARM: orion: Move cache-feroceon-l2.h out of plat-orion

With the gradual move to DT, kirkwood has become a lot less dependent on plat-orion. cache-feroceon-l2.h is the last dependency. Move it out so we can drop plat-orion when building DT only kirkwood boards. Signed-off-by: Andrew Lunn Acked-by: Arnd Bergmann Tested-by: Jason Gunthorpe Signed-off-by: Jason Cooper

ARM: plat-orion: add missing ehci include to common.h

2013-05-13T16:04:00Z

Removing orion ehci include from board files will raise a compiler error because plat/common.h is using an enum provided by orion ehci but not including the include itself. This just adds the missing include. Signed-off-by: Sebastian Hesselbarth Signed-off-by: Jason Cooper
