Add startup time to LDO regulators of S2MPS11 PMIC on Odroid XU3/XU4/HC1
family of boards to be sure the voltage is proper before relying on the

The datasheet for all the S2MPS1x family is inconsistent here and does
not specify unambiguously the value of ramp delay for LDO. It mentions
30 mV/us in one timing diagram but then omits it completely in LDO
regulator characteristics table (it is specified for bucks).
However the vendor kernels for Galaxy S5 and Odroid XU3 use values of 12
mV/us or 24 mV/us.
Without the ramp delay value the consumers do not wait for voltage
settle after changing it. Although the proper value of ramp delay for
LDOs is unknown, it seems safer to use at least some value from
reference kernel than to leave it unset.

arm: exynos: Detect revision later, when all resources are ready
Detection of board revision is done early - before power setup. In case of
Odroid XU3/XU4/HC1 family, the detection is done using ADC which
is supplied by LDO4/VDD_ADC regulator. This regulator could be turned
off (e.g. by kernel before reboot). If ADC is used early, the
regulators are not yet available and the detection won't work.
Split the revision detection out of set_board_type() into separate
function called later - either when displaying board info (in late mode)
or during misc_init_r. The idea is that set_board_type() will be called
early so its method of detection are limited to flattened device tree
(exynos5-dt-types.c for Exynos5) or GPIO (odroid.c for Exynos4412). The
newly added set_board_revision() can be called only later, when
resources like regulator are available.

an improvement.
Eventually we will want to have full DM functionality in runtime services.

we should pull it in without the amazing new RTS DM framework.

Hence, remove the SDHI/USB nodes from r8a77965-u-boot.dtsi. This is
equivalent to partially reverting below v2019.01 commits:
- f529bc551b6d ("ARM: dts: rmobile: Extract USB nodes on M3N")
- 830b94f76867 ("ARM: dts: rmobile: Extract SDHI nodes on M3N")
Duplicating the nodes from <soc>.dtsi to <soc>-u-boot.dtsi is obviously:
- not needed if no U-boot-specific changes are needed in those nodes.
- potentially dangerous/error-prone, since the duplicated properties
override the properties originally defined in <soc>.dtsi. One
possible consequence is that <soc>.dtsi is getting an update from
Linux, while <soc>-u-boot.dtsi stays unchanged. In this situation,
the obsolete property values from <soc>-u-boot.dtsi will take
precedence masking some of the <soc>.dtsi updates, potentially
leading to all kind of obscure issues.

of r8a77965-u-boot.dtsi) before and after the patch (slightly

What below output means is there is already a mismatch in some of

U-Boot customization is needed in SDHI/USB DT nodes, get rid of them in
