The MFD_SYSCON depends on HAS_IOMEM so when selecting it avoid unmet
direct dependencies.

Hmmm... you are right (here and in other patches) but why am I getting
all these errors:
warning: (ST_IRQCHIP && HIP04_ETH && STMMAC_PLATFORM && DWMAC_IPQ806X
&& DWMAC_LPC18XX && DWMAC_ROCKCHIP && DWMAC_SOCFPGA && DWMAC_STI &&
TI_CPSW && PINCTRL_ROCKCHIP && PINCTRL_DOVE && POWER_RESET_KEYSTONE &&
S3C2410_WATCHDOG && VIDEO_OMAP3 && VIDEO_S5P_FIMC && USB_XHCI_MTK &&
RTC_DRV_AT91SAM9 && LPC18XX_DMAMUX && VIDEO_OMAP4 && HWSPINLOCK_QCOM
&& ATMEL_ST && QCOM_GSBI && PHY_HI6220_USB) selects MFD_SYSCON which
has unmet direct dependencies (HAS_IOMEM)
?
(ARCH=um, allyesconfig)
Adding depends here (and in other places) really helps... but it
should not have any impact...

Thanks for comments,
Krzysztof

The problem is that Kconfig will just print any option that
selects the one that has a missing dependency, but doesn't
show which of those are actually enabled.

I think patch 5 by itself would have been sufficient.

Indeed... but apparently putting direct HAS_IOMEM dependency on these
symbols silences the Kconfig warning.

Thanks for analysis. Since all patches are independent (and IMHO the
last one is not needed really) so I won't resend the patchset. Instead
let maintainer pick what is meaningful.

Best regards,
