drivers: remove force dma flag from buses

2018-05-03T14:25:08Z

With each bus implementing its own DMA configuration callback, there is no need for bus to explicitly set the force_dma flag. Modify the of_dma_configure function to accept an input parameter which specifies if implicit DMA configuration is required when it is not described by the firmware.

bcma: fill core OF info independently of bus type

2017-03-20T17:12:01Z

PCI devices can be described in DT as well so we should always execute relevant code. This will make bcma e.g. set of_node for cores described in DT. Signed-off-by: Rafał Miłecki Signed-off-by: Kalle Valo

bcma: use helper function to set core dev's parent

2017-03-20T17:12:00Z

A tiny code deduplication thanks to the bcma_bus_get_host_dev. Signed-off-by: Rafał Miłecki Signed-off-by: Kalle Valo

bcma: drop unneeded check for CONFIG_OF_IRQ

2017-03-20T17:11:11Z

We already have the same check in bcma_of_get_irq which really calls symbols available with CONFIG_OF_IRQ only. It appears this duplicated check was accidentally added in commit c58d900cc96a ("bcma: fix building without OF_IRQ"). The rest of code in bcma_of_fill_device should work fine without CONFIG_OF_IRQ.

bcma: make OF code more generic (not platform_device specific)

2017-01-31T07:28:34Z

OF allows not only specifying platform devices but also describing devices on standard buses like PCI or USB. This change will allow reading info from DT for bcma buses hosted on PCI cards. Signed-off-by: Rafał Miłecki Signed-off-by: Kalle Valo

bcma: use (get|put)_device when probing/removing device driver

2017-01-31T07:27:09Z

This allows tracking device state and e.g. makes devm work as expected. Signed-off-by: Rafał Miłecki Cc: Stable Signed-off-by: Kalle Valo

bcma: use of_dma_configure() to set initial dma mask

2016-09-09T09:00:37Z

While fixing another bug, I noticed that bcma manually sets up a dma_mask pointer for its child devices. We have a generic helper for that now, which should be able to cope better with any variations that might be needed to deal with cache coherency, unusual DMA address offsets, iommus, or limited DMA masks, none of which are currently handled here. This changes the core to use the of_dma_configure(), like we do for platform devices that are probed directly from DT. Signed-off-by: Arnd Bergmann Signed-off-by: Kalle Valo

bcma: fix building without OF_IRQ

2016-03-23T15:52:10Z

The bcma driver core can be built with or without DT support, but it fails to build when CONFIG_OF=y and CONFIG_OF_IRQ=n, which can happen on platforms that do not support IRQ domains. ERROR: "irq_create_of_mapping" [drivers/bcma/bcma.ko] undefined! ERROR: "of_irq_parse_raw" [drivers/bcma/bcma.ko] undefined! ERROR: "of_irq_parse_one" [drivers/bcma/bcma.ko] undefined! This adds another compile-time check for OF_IRQ, but also gets rid of now unneeded #ifdef checks: Using the simpler IS_ENABLED() check for OF_IRQ also covers the case of not having CONFIG_OF enabled. The check for CONFIG_OF_ADDRESS was added to allow building on architectures without OF_ADDRESS, but that has been addressed already in b1d06b60e90c ("of: Provide static inline function for of_translate_address if needed").

bcma: move parallel flash support to separated file

2016-03-07T12:41:08Z

This follows the way of handling other flashes and cleans code a bit. As next task we will want to move flash code to ChipCommon driver as: 1) Flash controllers are accesible using ChipCommon registers 2) This code isn't MIPS specific This change prepares bcma for that.

bcma: use module_init for the main part of bus initialization

2015-12-31T08:17:05Z

So far we were using fs_initcall. It was (and still is) needed because struct bus_type has to be registered early. However main bus initialization has to happen later as it requires SPROM which depends on NVRAM which depends on mtd. Solve it by using fs_initcall only for bus_register call and module_init for the rest. It affects bcma only when built-in obviously. This was tested with BCM4706 and BCM5357C0 (BCM47XX), BCM4708A0 (ARCH_BCM_5301X) and BCM43225 (PCIe card with bcma as module). Signed-off-by: Rafał Miłecki Signed-off-by: Kalle Valo
