Merge tag 'soc-for-linus-2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC platform updates (part 2) from Arnd Bergmann: "These patches are all for Renesas shmobile, and depend on the earlier pinctrl updates. Remarkably, this adds support for three new SoCs: r8a73a4, r8a73a4 and r8a7778. The bulk of the code added for these is for pinctrl (using the new subsystem) and for clocks (not yet using the common clock subsystem). The latter will have to get converted in one of the upcoming releases, but shmobile is not ready for that yet. The series also contains Renesas shmobile board changes, adding one board file for each of the three new SoCs. These boards are using a mix of classic and device-tree based probing, as there is still a lot of infrastructure in shmobile that has not been converted to DT yet. Once those are resolved to the degree that no board specific setup code is needed, they can get folded into the respective SoC setup files." * tag 'soc-for-linus-2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (78 commits) ARM: shmobile: use r8a7790 timer setup code on Lager ARM: shmobile: force enable of r8a7790 arch timer ARM: shmobile: Add second I/O range for r8a7790 PFC ARM: shmobile: bockw: enable network settings on bootargs ARM: shmobile: bockw: add SMSC ethernet support ARM: shmobile: R8A7778: add Ether support ARM: shmobile: bockw: enable SMSC ethernet on defconfig ARM: shmobile: r8a7778: add r8a7778_init_irq_extpin() ARM: shmobile: r8a7778: remove pointless PLATFORM_INFO() ARM: shmobile: mackerel: clean up MMCIF vs. SDHI1 selection ARM: shmobile: mackerel: add interrupt names for SDHI0 ARM: shmobile: mackerel: switch SDHI and MMCIF interfaces to slot-gpio ARM: shmobile: mackerel: remove OCR masks, where regulators are used ARM: shmobile: mackerel: SDHI resources do not have to be numbered ARM: shmobile: Initial r8a7790 Lager board support ARM: shmobile: APE6EVM LAN9220 support ARM: shmobile: APE6EVM PFC support ARM: shmobile: APE6EVM base support ARM: shmobile: kzm9g-reference: add ethernet support ARM: shmobile: add R-Car M1A Bock-W platform support ...
