staging: fsl-mc: be consistent when checking strcmp() returns

2017-08-23T23:22:32+00:00

Throughout the driver we use == 0 / != 0 to check strcmp() returns except
this place, so fix it.

Revert "staging: fsl-mc: be consistent when checking strcmp() return"

2017-08-16T18:12:06+00:00

The previous fix removed the equal to zero comparisons by the strcmps and
now the function always returns true. Revert this change to restore the
original correctly functioning code.

staging: fsl-mc: add explicit dependencies for compile-tested arches

2017-08-14T22:18:25+00:00

The driver makes use of GENERIC_MSI_IRQ_DOMAIN which requires arch
support so, on architectures that don't have it, the kernel will fail
to build. Add explicit dependency on architectures that were
compile-tested, thus fixing compilation for the ones that don't
implement GENERIC_MSI_IRQ_DOMAIN.

staging: fsl-mc: fix resource_size.cocci warnings

2017-08-14T22:18:25+00:00

Use resource_size() function on resource objects instead of
explicit computation.

This patch fixes the following coccinelle warning:

staging: fsl-mc: include irqreturn.h as needed

2017-07-30T15:25:04+00:00

The recent reshuffling of header files left one type definition
missing in some configurations:

In file included from drivers/staging/fsl-dpaa2/ethernet/dpaa2-eth.h:39:0,
                 from drivers/staging/fsl-dpaa2/ethernet/dpaa2-ethtool.c:34:
drivers/staging/fsl-dpaa2/ethernet/../../fsl-mc/include/dpaa2-io.h:86:1: error: unknown type name 'irqreturn_t'; did you mean 'irq_count'?
 irqreturn_t dpaa2_io_irq(struct dpaa2_io *obj);

I have not bisected this to the exact patch that introduced the problem,
but the solution is obvious, we just need to include the header that
contains the type.

staging: fsl-mc/dpio: Skip endianness conversion in portal config

2017-07-30T15:25:04+00:00

Writing to the register using writel does the CPU to LE conversion down the
line, so it's not required here. Doing it breaks portal configuration on
big endian kernels.

staging: fsl-mc: allow the driver compile multi-arch

2017-07-30T15:23:28+00:00

Add an alternate dependency on COMPILE_TEST, thus leaving
this driver compile on other architectures.
Also, other drivers depending on the bus are updated to depend
on ARCH_LAYERSCAPE until they'll also be made multi-arch.
This was compiled tested on:
 - booke powerpc (corenet{32,64}_smp_defconfig)
 - x86 (i386_defconfig, x86_64_defconfig, needs CONFIG_OF)
 - arm64 (defconfig)

staging: fsl-mc: make the driver compile on 32-bit

2017-07-30T15:23:28+00:00

Since there's no real constrain in MC to do only atomic 64-bit we can
enable this driver on 32-bit platforms too.
Include linux/io-64-nonatomic-hi-lo.h to make quad device io apis used
in the driver available on 32-bit platforms.
