Merge tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARM SoC platform updates from Olof Johansson: "SoC changes, a substantial part of this is cleanup of some of the older platforms that used to have a bunch of board files. In particular: - Remove non-DT i.MX platforms that haven't seen activity in years, it's time to remove them. - A bunch of cleanup and removal of platform data for TI/OMAP platforms, moving over to genpd for power/reset control (yay!) - Major cleanup of Samsung S3C24xx and S3C64xx platforms, moving them closer to multiplatform support (not quite there yet, but getting close). There are a few other changes too, smaller fixlets, etc. For new platform support, the primary ones are: - New SoC: Hisilicon SD5203, ARM926EJ-S platform. - Cpufreq support for i.MX7ULP" * tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (121 commits) ARM: mstar: Select MStar intc ARM: stm32: Replace HTTP links with HTTPS ones ARM: debug: add UART early console support for SD5203 ARM: hisi: add support for SD5203 SoC ARM: omap3: enable off mode automatically clk: imx: imx35: Remove mx35_clocks_init() clk: imx: imx31: Remove mx31_clocks_init() clk: imx: imx27: Remove mx27_clocks_init() ARM: imx: Remove unused definitions ARM: imx35: Retrieve the IIM base address from devicetree ARM: imx3: Retrieve the AVIC base address from devicetree ARM: imx3: Retrieve the CCM base address from devicetree ARM: imx31: Retrieve the IIM base address from devicetree ARM: imx27: Retrieve the CCM base address from devicetree ARM: imx27: Retrieve the SYSCTRL base address from devicetree ARM: s3c64xx: bring back notes from removed debug-macro.S ARM: s3c24xx: fix Wunused-variable warning on !MMU ARM: samsung: fix PM debug build with DEBUG_LL but !MMU MAINTAINERS: mark linux-samsung-soc list non-moderated ARM: imx: Remove remnant board file support pieces ...
