The phy is necessary for the dwc2 controllers driving the usb ports
on all arm32 Rockchip socs. Both the dwc2 as well as usb downstream
drivers (mass-storage as well as usb networking) are already built-in,
so only the phy is missing to allow booting from usb-devices without
to much hassle.

We only need to have MFD_CPCAP and CPCAP_REGULATOR as built-in to
be able to mount root on the eMMC. And then POWER_RESET_GPIO
is good to have built-in. The rest of the devices can be loadable
modules.

This gets various devices such as regulators, touchscreen, power
button, HDMI audio, LEDs, RTC, and ADC working.

Note that omapdrm needs to be configured manually as we're still

The imx6sl-evk board has a LAN8720A ethernet phy supported by SMSC_PHY.
Add this driver to the default imx config since the device is present on
one of the evaluation boards.

This used to work mostly fine with the generic phy driver until
commit 0878fff1 ("net: phy: Do not perform software reset for
Generic PHY"). The fact that soft reset is no longer performed
apparently causes RX to sometimes failes which can cause netboot to
timeout on DHCP. This is eventually retried and it works after link
up/down but can takes 90 seconds to reach the login prompt.

This was generated with "make savedefconfig" and it includes a few
additional minor cleanups.

IDE subsystem has been deprecated since 2009 and the majority
(if not all) of Linux distributions have switched to use
libata for ATA support exclusively.  However there are still
some users (mostly old or/and embedded non-x86 systems) that
have not converted from using IDE subsystem to libata PATA
drivers.  This doesn't seem to be good thing in the long-term
for Linux as while there is less and less PATA systems left
in use:

* testing efforts are divided between two subsystems

* having duplicate drivers for same hardware confuses users

This patch converts davinci_all_defconfig to use libata PATA
drivers.

On some DDR controllers, compatible with the sama5d3 one,
the sequence to enter/exit/re-enter the self-refresh mode adds
more constrains than what is currently written in the at91_idle
driver. An actual access to the DDR chip is needed between exit
and re-enter of this mode which is somehow difficult to implement.
This sequence can completely hang the SoC. It is particularly
experienced on parts which embed a L2 cache if the code run
between IDLE calls fits in it...

Moreover, as the intention is to enter and exit pretty rapidly
from IDLE, the power-down mode is a good candidate.

So now we use power-down instead of self-refresh. As we can
simplify the code for sama5d3 compatible DDR controllers,
we instantiate a new sama5d3_ddr_standby() function.

Current CMA size of 64 Mbytes is right on the edge of being small when
several drivers need to allocate large CMA buffers.

For example, if the s5p-mfc driver needs to pre-allocate CMA memory to
decode a H.264 1080p video, then there won't be enough CMA memory left
for other drivers, such as the exynos-drm driver that may need to
allocate GEM buffers for the display manager.

Increasing CMA size to 96 Mbytes in exynos_defconfig addresses use-cases
such as these.

Currently we BUG() if we see a HSR.EC value we don't recognise. As
configurable disables/enables are added to the architecture (controlled
by RES1/RES0 bits respectively), with associated synchronous exceptions,
it may be possible for a guest to trigger exceptions with classes that
we don't recognise.

While we can't service these exceptions in a manner useful to the guest,
we can avoid bringing down the host. Per ARM DDI 0406C.c, all currently
unallocated HSR EC encodings are reserved, and per ARM DDI
0487A.k_iss10775, page G6-4395, EC values within the range 0x00 - 0x2c
are reserved for future use with synchronous exceptions, and EC values
within the range 0x2d - 0x3f may be used for either synchronous or
asynchronous exceptions.

The patch makes KVM handle any unknown EC by injecting an UNDEFINED
exception into the guest, with a corresponding (ratelimited) warning in
the host dmesg. We could later improve on this with with a new (opt-in)
exit to the host userspace.
