The LiteX SOC controller driver makes use of IOMEM functions like devm_platform_ioremap_resource(), which are only available if CONFIG_HAS_IOMEM is defined. This causes the driver to be enable under make ARCH=um allyesconfig, even though it won't build.

2021-01-29soc: renesas: rcar-sysc: Mark device node OF_POPULATED after initGeert Uytterhoeven
The R-Car System Controller (SYSC) driver registers PM domains from an early_initcall(). It does not use a platform driver, as secondary CPU startup on R-Car H1 needs to control the CPU power domains, before initialization of the driver framework. As fw_devlink only considers devices, it does not know that the System Controller is ready. Hence probing of on-chip devices that are part of the SYSC PM domain fails if fw_devlink is enabled: probe deferral - supplier e6180000.system-controller not ready Fix this by setting the OF_POPULATED flag for the SYSC device node after successful initialization. This will make of_link_to_phandle() ignore the SYSC device node as a dependency, and consumer devices will be probed again.

Add a helper that takes a virtual address rather than the muram offset. This will be used in a couple of places to avoid having to store both the offset and the virtual address, as well as removing NULL checks from the callers.

2021-01-21soc: fsl: qe: store muram_vbase as a void pointer instead of u8Rasmus Villemoes
The two functions cpm_muram_offset() and cpm_muram_dma() both need a cast currently, one casts muram_vbase to do the pointer arithmetic on void pointers, the other casts the passed-in address u8*. It's simpler and more consistent to just always use void* and drop all the casting.

2021-01-20ARM: remove zte zx platformArnd Bergmann
The ZTE ZX set-top-box SoC platform was added in 2015 by Jun Nie, with Baoyou Xie and Shawn Guo subsequently becoming maintainers after the addition of the 64-bit variant. However, the only machines that were ever supported upstream are the reference designs, not actual set-top-box devices that would benefit from this support. All ZTE set-top-boxes from the past few years seem to be based on third-party SoCs. While there is very little information about zx296702 and zx296718 on the web, I found some references to other chips from the same family, such as zx296716 and zx296719, which were never submitted for upstream support. Finally, there is no support for the GPU on either of them, with the lima and panfrost device drivers having been added after work on the zx platform had stopped. Shawn confirmed that he has not seen any interest in this platform for the past four years, and that it can be removed. Thanks to Jun and Shawn for maintaining this platform over the past five years.

2021-01-15soc: samsung: pm_domains: Convert to regular platform driverMarek Szyprowski
When Exynos power domain driver was introduced, the only way to ensure that power domains will be instantiated before the devices which belongs to them was to initialize them early enough, before the devices are instantiated in the system. This in turn required not to use any platform device infrastructure at all, as there have been no way to ensure proper probe order between devices. This has been finally changed and upcomming patch "driver core: Set fw_devlink=on by default" ensures that each device will be probbed only when its resource providers are ready. This allows to convert Exynos power domain driver to regular platform driver. This is also required by the mentioned commit to enable probing any device which belongs to the Exynos power domains, as otherwise the core won't notice that the power domains are in fact available.
