devres: show which resource was invalid in __devm_ioremap_resource()

2023-06-24T00:04:04+00:00

The other error prints in this call show the resource which wsan't valid,
so add this to the first print when it checks for basic validity of the
resource.

devm_ioremap_np has never been used anywhere since it was added in early
2021, so remove it.

lib: devres: Add managed arch_io_reserve_memtype_wc()

2021-09-23T07:25:59+00:00

Add devm_arch_io_reserve_memtype_wc() as managed wrapper around
arch_io_reserve_memtype_wc(). Useful for several graphics drivers
that set framebuffer memory to write combining.

lib: devres: Add error information printing for __devm_ioremap_resource()

2021-05-14T11:48:16+00:00

Ensure that all error handling branches print error information. In this
way, when this function fails, the upper-layer functions can directly
return an error code without missing debugging information. Otherwise,
the error message will be printed redundantly or missing.

asm-generic/io.h: Add a non-posted variant of ioremap()

2021-04-08T11:18:38+00:00

ARM64 currently defaults to posted MMIO (nGnRE), but some devices
require the use of non-posted MMIO (nGnRnE). Introduce a new ioremap()
variant to handle this case. ioremap_np() returns NULL on arches that
do not implement this variant.

sparc64 is the only architecture that needs to be touched directly,
because it includes neither of the generic io.h or iomap.h headers.

This adds the IORESOURCE_MEM_NONPOSTED flag, which maps to this
variant and marks a given resource as requiring non-posted mappings.
This is implemented in the resource system because it is a SoC-level
requirement, so existing drivers do not need special-case code to pick
this ioremap variant.

Then this is implemented in devres by introducing devm_ioremap_np(),
and making devm_ioremap_resource() automatically select this variant
when the resource has the IORESOURCE_MEM_NONPOSTED flag set.

driver core: platform: Document return type of more functions

2020-09-10T16:30:01+00:00

I can't always remember the return values of these functions, and so I
usually jump to the function to read the kernel-doc and see that it
doesn't tell me. Then I have to spend more time reading the code to jump
to the function that actually tells me the return values. Let's document
it here so that we don't all have to spend time digging through the code
to understand the return values.
