Fourth Round of Renesas ARM based SoC fixes for v3.12 * Remove unused #gpio-ranges-cells DT property * Remove usage of deprecated #gpio-range-cells DT property from GPIO R-Car Property was deprecated in v3.11-rc2 * Correct ether pinctl naming for armadillo800eva board Regression introduced in v3.10-rc5 * Add Micrel KSZ8041 PHY fixup to lager board This resolves a problem that has been present since 3.11-rc2 * Update SDHI DT compatibility string to the <unit>-<soc> format This makes compatibility strings consistent across all renesas hardware which currently supports DT. The bindings which are being updated where intorodiced on a per-SoC basis starting in v3.8-rc7. They may have been internally consistent when originally added.

Add information to the shared APMU code regarding the APMU instance used to control the CA7 cores. This can be used on r8a7790 and r8a73a4, but should most likely be converted to DT in the future.

Extend the APMU code with a check to only allow boot of CPU cores that sit in the same cluster as CPU0. This makes it possible for people to use the r8a790 CA7 boot mode with CA7-cores only. The default CA15 boot mode will enable CA15 cores only. This is an intentional software limitation to cope with lacking scheduler support. By removing this patch it is possible to run all 8 cores in parallel, but this is not recommended without out of tree scheduler modfications or custom user space code to control the CPU affinitiy.

Introduce shared APMU SMP code for mach-shmobile. Both SMP boot up and CPU Hotplug is supported. This version does not use DT but if needed this will be added as an incremental feature patch. The code is designed around CONFIG_NR_CPUS and should in theory support any number of APMUs, however due to the current DT-less static design only a single APMU is supported.

Sergei Shtylyov authored
Currently on the Lager board NFS timeouts/delays are seen when booting. That turned out to happen because the SoC's ETH_LINK signal turns on and off after each packet. It is connected to Micrel KSZ8041 PHY's LED0 signal. Ether LEDs on the Lager board are named LINK and ACTIVE which corresponds to non-default 01 setting of the PHY control register 1 bits 14-15. The 'sh_eth' driver resets the PHY when opening the network device, so we have to set the mentioned bits back to 01 from the default 00 value which causes bouncing of ETH_LINK. That can be achieved using the PHY platform fixup mechanism if we also modify the driver to use it..

Currently DT compatibility strings of both types can be found in the kernel sources: <unit>-<soc> and <soc>-<unit>, whereas a unique format should be followed and the former one is preferred. This patch converts the SDHI MMC driver and its users to the common standard. This is safe for now, since ATM no real products are using this driver with DT.
