drivers: provide devm_platform_ioremap_resource_byname()

2019-11-05T17:33:13Z

Provide a variant of devm_platform_ioremap_resource() that allows to lookup resources from platform devices by name rather than by index.

sh: add the sh_ prefix to early platform symbols

2019-10-07T11:50:48Z

Old early platform device support is now sh-specific. Before moving on to implementing new early platform framework based on real platform devices, prefix all early platform symbols with 'sh_'.

drivers: move the early platform device support to arch/sh

2019-10-07T11:50:47Z

SuperH is the only user of the current implementation of early platform device support. We want to introduce a more robust approach to early probing. As the first step - move all the current early platform code to arch/sh. In order not to export internal drivers/base functions to arch code for this temporary solution - copy the two needed routines for driver matching from drivers/base/platform.c to arch/sh/drivers/platform_early.c. Also: call early_platform_cleanup() from subsys_initcall() so that it's called after all early devices are probed.

driver core: platform: Add platform_get_irq_byname_optional()

2019-10-07T10:52:44Z

Some drivers (e.g dwc3) first try to get an IRQ byname and then fall back to the one at index 0. In this case we do not want the error(s) printed by platform_get_irq_byname(). This commit adds a new platform_get_irq_byname_optional(), which does not print errors, for this. While at it also improve the kdoc text for platform_get_irq_byname() a bit.

Merge tag 'usb-5.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

2019-09-18T17:33:46Z

Pull USB updates from Greg KH: "Here is the big set of USB patches for 5.4-rc1. Two major chunks of code are moving out of the tree and into the staging directory, uwb and wusb (wireless USB support), because there are no devices that actually use this protocol anymore, and what we have today probably doesn't work at all given that the maintainers left many many years ago. So move it to staging where it will be removed in a few releases if no one screams. Other than that, lots of little things. The usual gadget and xhci and usb serial driver updates, along with a bunch of sysfs file cleanups due to the driver core changes to support that. Nothing really major, just constant forward progress.

driver core: platform: Introduce platform_get_irq_optional()

2019-08-28T20:52:30Z

In some cases the interrupt line of a device is optional. Introduce a new platform_get_irq_optional() that works much like platform_get_irq() but does not output an error on failure to find the interrupt.

driver core: initialize a default DMA mask for platform device

2019-08-22T16:41:55Z

We still treat devices without a DMA mask as defaulting to 32-bits for both mask, but a few releases ago we've started warning about such cases, as they require special cases to work around this sloppyness. Add a dma_mask field to struct platform_device so that we can initialize the dma_mask pointer in struct device and initialize both masks to 32-bits by default, replacing similar functionality in m68k and powerpc. The arch_setup_pdev_archdata hooks is now unused and removed. Note that the code looks a little odd with the various conditionals because we have to support platform_device structures that are statically allocated.
