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 ...

2020-01-15usb: musb: davinci: Convert to use GPIO descriptorLinus Walleij1-0/+12
The DaVinci MUSB glue contains an optional GPIO line to control VBUS power, convert this to use a GPIO descriptor and augment the EVM board file to provide this descriptor. I can't get this driver to compile properly and it depends on broken but when I didn get it to compile brokenly, it did at least not complain about THIS code being broken so I don't think I broke the driver any more than what it already is. I did away with the ifdefs that do not work with multiplatform anyway so the day someone decides to resurrect the code, the path to get it working should be easier as well since DaVinci is now multiplatform.
