arm: make sa1111_bus_type const

2025-10-22T05:54:54Z

Because driver core can properly handle constant struct bus_type, move the sa1111_bus_type to be a constant structure as well, placing it into read-only memory which can not be modified at runtime.

ARM: sa1100: make match function take a const pointer

2024-07-19T11:47:20Z

In commit d69d80484598 ("driver core: have match() callback in struct bus_type take a const *"), the match callback for busses was changed to take a const pointer to struct device_driver. Unfortunately I missed fixing up the sa1111 code, and was only noticed after-the-fact by the kernel test robot. Resolve this issue by properly changing the sa111_match() function.

ARM: pxa: remove unused mach/bitfield.h

2022-05-07T20:56:16Z

The sa1111.h header defines some constants using the bitfield macros, but those are only used on sa1100, not on pxa, and the users include the bitfield header through mach/hardware.h. Acked-by: Robert Jarzmik Signed-off-by: Arnd Bergmann

ARM: 9048/1: sa1111: make sa1111 bus's remove callback return void

2021-02-01T19:42:13Z

The driver core ignores the return value of struct device_driver::remove because there is only little that can be done. To simplify the quest to make this function return void, let struct sa1111_driver::remove return void, too. All users already unconditionally return 0, this commit makes it obvious that returning an error code is a bad idea and ensures future users behave accordingly.

ARM: sa1111: remove legacy GPIO interfaces

2018-12-04T22:37:38Z

Now that we have migrated all users of the legacy private SA1111 gpio interfaces, we can remove these redundant GPIO interfaces. Signed-off-by: Russell King

ARM: sa1111: map interrupt numbers through irqdomain

2017-11-29T10:57:41Z

Map the interrupt numbers for SA1111 through the SA1111 IRQ domain rather than doing our own translation. This allows us to eliminate the irq_base sachip member. Signed-off-by: Russell King

ARM: sa1111: remove some redundant definitions

2017-11-29T10:57:41Z

SA1111_VBASE, SA1111_p2v, SA1111_v2p, _SA1111, SA1111_ADDR_WIDTH, SA1111_ADDR_MASK, and SA1111_DMA_ADDR are not used anywhere in the kernel, so remove these redundant definitions. Signed-off-by: Russell King

ARM: sa1111: remove special sa1111 mmio accessors

2017-11-29T10:57:41Z

Remove the special sa1111 mmio accessors from core sa1111 code, and their definition in sa1111.h now that all users are gone. Signed-off-by: Russell King

ARM: sa1111: remove legacy suspend/resume methods

2017-11-29T10:57:34Z

The legacy device-driver suspend/resume methods are not used by any of our drivers, so let's remove this redundant code. Acked-by: Rafael J. Wysocki Signed-off-by: Russell King

ARM: sa1111: remove legacy shutdown method

2017-11-27T14:26:39Z

Since the only user of the SA1111 device driver shutdown method has now gone, we can kill the bus level support code and the entry in the sa1111 device driver structure. Signed-off-by: Russell King
