Hi everyone,
This is v5 of my A80 USB support series. v5 addresses some comments
on the phy driver, and adds a patch switching the dts from phy driver
regulator bindings to phy core bindings.
Changes since v4:
- Fixed copyright date
- Dropped unused header files
- Dropped regulator
Since the phy core already supports specifying a regulator to handle
during power up/down, it was decided to drop the regulator support
in the sun9i usb phy driver.
This patch switches the DT to the core bindings. This and the phy driver
would be in the same release and should not be a problem as
Unlike previous Allwinner SoCs, there is no central PHY control block
on the A80. Also, OTG support is completely split off into a different
controller.
This adds a new driver to support the regular USB PHYs.

Drop AT91_TIMER_HZ as this can be handled using HZ_FIXED. Initial help message
was:
On AT91rm9200 chips where you're using a system clock derived
from the 32768 Hz hardware clock, this tick rate should divide
it exactly: use a power-of-two value, such as 128 or 256, to
reduce timing errors caused
mach/cpu.h is not used anymore, remove it.

Actually, the switch to

AT91 is now ready to switch to multiplatform. Do it and clean the remaining mach
includes.
Changes in v3:
- use a menu structure as asked by Arnd
- remove useless selects as pointed by Rob
- drop a patch that has already been applied
- add a patch to remove AT91_TIMER_HZ
Changes in v2:
-
Following the switch to multiplatform, uncompress.h is not used anymore. Remove
it.
at91_dbgu.h is also not used anymore

UEFI Secure Boot provides a mechanism for ensuring that the firmware will
only load signed bootloaders and kernels. Certain use cases may also
require that the kernel prevent userspace from inserting untrusted kernel
code at runtime. Add a configuration option that enforces this automatically
when
Permitting write access to MSRs allows userspace to modify the running
kernel. Prevent this if trusted_kernel is true. Based on a patch by Kees
Cook.

We have no way of validating what all of the Asus WMI methods do on a
given machine, and there's a risk that some will allow hardware state to
be manipulated in such a way that arbitrary code can be executed in the
kernel. Prevent that if trusted_kernel is true.
