Merge tag 'renesas-kconfig-cleanups-for-v3.18' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas into next/cleanup
Pull "Renesas ARM Based SoC Kconfig Cleanups for v3.18" from Simon Horman: * Update name of "R-Car M2-W" SoC (previously there was no "-W") * Consolidate Legacy SH_CLK_CPG and CPU_V7 Kconfig * Only select PM_RMOBILE for legacy case * Cleanup pm-rcar.o and pm-rmobile.o build using Kconfig Signed-off-by: Arnd Bergmann <arnd@arndb.de> * tag 'renesas-kconfig-cleanups-for-v3.18' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas: ARM: shmobile: r8a7791 is now called "R-Car M2-W" ARM: shmobile: Consolidate Legacy SH_CLK_CPG Kconfig ARM: shmobile: Consolidate Legacy CPU_V7 Kconfig ARM: shmobile: Only select PM_RMOBILE for legacy case ARM: shmobile: Cleanup pm-rmobile.o build using Kconfig ARM: shmobile: Cleanup pm-rcar.o build using Kconfig ARM: shmobile: Introduce a Kconfig entry for R-Car Gen2 ARM: shmobile: Introduce a Kconfig entry for R-Car Gen1 ARM: shmobile: Introduce a Kconfig entry for R-Mobile Includes an update to 3.17-rc2 to avoid a dependency
