2019-08-29soc: ixp4xx: Protect IXP4xx SoC drivers by ARCH_IXP4XX || COMPILE_TESTGeert Uytterhoeven1-0/+4
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.

2019-04-23soc: ixp4xx: qmgr: Add DT probe codeLinus Walleij1-0/+8
This makes the queue manager driver able to probe from the device tree. It only needs to get a memory resource and two interrupts and the platform device provides these as resources, so all is pretty simple. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2019-04-23soc: ixp4xx: npe: Add DT probe codeLinus Walleij1-0/+8
This makes the NPE driver able to probe from the device tree. It only needs to get three memory resources and the plaform device provide these, so all is pretty simple. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2019-04-23soc: ixp4xx: qmgr: Pass resourcesLinus Walleij1-36/+35
Instead of using hardcoded base address implicitly obtained through <linux/io.h>, pass the physical base for the QMGR block as a memory resource and remap it in the driver. Also pass the two IRQs as resources and obtain them in the driver. Use devm_* accessors and simplify the error path in the process. Drop memory region request as this is done by the devm_ioremap* functions. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2019-04-23soc: ixp4xx: Remove unused functionsLinus Walleij1-23/+0
These former inlines turn out to be unused in the kernel. If they are needed in the future, they can be resurrected by reverting or studying this commit. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2019-04-23soc: ixp4xx: Uninline several functionsLinus Walleij1-0/+117
These inline functions immediately exploit the static ioremaps for the queue manager memory region. This does not work with multiplatform where everything need to be dynamically remapped, so get rid of these inlines and create new exports for those used by other drivers.

2019-04-23soc: ixp4xx: npe: Pass addresses as resourcesLinus Walleij1-16/+20
Instead of using hardcoded base addresses implicitly obtained through <linux/io.h>, pass the physical base for the three NPE blocks as memory resources and remap these in the driver. Drop the memory request region business, this will anyways be done by devm_* remapping functions. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2019-04-23ARM: ixp4xx: Turn the QMGR into a platform deviceLinus Walleij1-8/+13
Instead of registering everything related to the QMGR unconditionally in the module_init() call (which will never work with multiplatform) create a platform device and probe the QMGR like any other device. Put the device second in the list of devices added for the platform so it is there when the dependent network and crypto drivers probe later on. This probe() path will not be taken unconditionally on device tree boots, so remove the DT guard. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

2019-04-23ARM: ixp4xx: Move IXP4xx QMGR and NPE headersLinus Walleij2-2/+2
This moves the IXP4xx Queue Manager and Network Processing Engine headers out of the <mack/*> include path as that is incompatible with multiplatform. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2019-04-23ARM: ixp4xx: Move NPE and QMGR to drivers/socLinus Walleij4-0/+1147
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>
