soc: ixp4xx: Protect IXP4xx SoC drivers by ARCH_IXP4XX || COMPILE_TEST The move of the IXP4xx SoC drivers exposed their config options on all platforms. Fix this by wrapping them inside an ARCH_IXP4XX or COMPILE_TEST block.

ARM: ixp4xx: Move NPE and QMGR to drivers/soc The Network Processing Engine and Queue Manager are versatile firmware components used by several IXP4xx drivers. Drivers are relying on getting access to these components using <mach/*> headers which does not work with multiplatform. We need to find a better place for the drivers to live. Let's first move them to drivers/soc and the start to refactor a bit by passing resources and moving headers. This patch introduce static IRQ assignments but that will be fixed by later patches in this series. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

soc: ixp4xx-npe: Access syscon regs using regmap If we access the syscon (expansion bus config registers) using the syscon regmap instead of relying on direct accessor functions, we do not need to call this static code in the machine (arch/arm/mach-ixp4xx/common.c) which makes things less dependent on custom machine-dependent code. Look up the syscon regmap and handle the error: this will make deferred probe work with relation to the syscon.
