Enabling the compile test should not cause automatic enabling of all
drivers.

Older Exynos designs, like Exynos5422, do not have USB Type-C and the
USB DRD PHY does not really need CONFIG_TYPEC for these devices at all.
Incorrectly added optional dependency on CONFIG_TYPEC caused this driver
to be missing for exynos_defconfig and as result Exynos5422-based boards
like Hardkernel Odroid HC1 failed to probe USB.

gs101's SS phy needs to be configured differently based on the
connector orientation, as the SS link can only be established if the
mux is configured correctly.
The code to handle programming of the mux is in place already, this commit
now adds the missing pieces to subscribe to the Type-C orientation
switch event.
Note that for this all to work we rely on the USB controller
re-initialising us. It should invoke our .exit() upon cable unplug, and
during cable plug we'll receive the orientation event after which we
expect our .init() to be called.
Above reinitialisation happens if the DWC3 controller can enter runtime
suspend automatically. For the DWC3 driver, this is an opt-in:
echo auto > /sys/devices/.../11110000.usb/power/control
Once done, things work as long as the UDC is not bound as otherwise it
stays busy because it doesn't cancel / stop outstanding TRBs. For now
we have to manually unbind the UDC in that case:
echo "" > sys/kernel/config/usb_gadget/.../UDC
Note that if the orientation-switch property is missing from the DT,
the code will behave as before this commit (meaning for gs101 it will
work in SS mode in one orientation only). Other platforms are not
affected either way.

Now exynos-pmu can register its custom regmap for gs101 via
of_syscon_register_regmap() we can switch back to the standard
syscon_regmap_lookup_by_phandle() api for obtaining the regmap.
Additionally add a Kconfig dependency for MFD_SYSCON.

Support for the Exynos4212 SoC was originally dropped as there were
no boards using it. We will be adding a device that uses it, so add
it back.

We use everywhere "Samsung" and "Exynos", not the uppercase versions.
Describe better which driver applies to which SoC, to make configuring

Fix up inconsistent usage of upper and lowercase letters in "Exynos"
name.
"EXYNOS" is not an abbreviation but a regular trademarked name.
Therefore it should be written with lowercase letters starting with
capital letter.
The lowercase "Exynos" name is promoted by its manufacturer Samsung
Electronics Co., Ltd., in advertisement materials and on website.

Pull USB/Thunderbolt/PHY driver updates from Greg KH:
"Here is the big USB and Thunderbolt and PHY driver updates for
5.6-rc1.
With the advent of USB4, "Thunderbolt" has really become USB4, so the
renaming of the Kconfig option and starting to share subsystem code
has begun, hence both subsystems coming in through the same tree here.
PHY driver updates also touched USB drivers, so that is coming in
through here as well.
Major stuff included in here are:
- USB 4 initial support added (i.e. Thunderbolt)
- musb driver updates
- USB gadget driver updates
- PHY driver updates
- USB PHY driver updates
- lots of USB serial stuff fixed up
- USB typec updates
- USB-IP fixes
- lots of other smaller USB driver updates
All of these have been in linux-next for a while now (the usb-serial
tree is already tested in linux-next on its own before merged into
here), with no reported issues"
