We can now probe devices with ti-sysc interconnect driver and dts
data. Let's drop the custom ti,hwmods dts property. We have already
dropped the platform data earlier, but have been still allocating it
dynamically, which is no longer needed.

- Update more panel options in omap2plus_defconfig that got changed

- Remove unused twl_keypad for logicpd-torpedo-som to avoid boot

Implement the service call for configuring a shared structure between a
VCPU and the hypervisor in which the hypervisor can write the time
stolen from the VCPU's execution time by other tasks on the host.
User space allocates memory which is placed at an IPA also chosen by user
space. The hypervisor then updates the shared structure using
kvm_put_guest() to ensure single copy atomicity of the 64-bit value
reporting the stolen time in nanoseconds.
Whenever stolen time is enabled by the guest, the stolen time counter is
reset.
The stolen time itself is retrieved from the sched_info structure
maintained by the Linux scheduler code. We enable SCHEDSTATS when
selecting KVM Kconfig to ensure this value is meaningful.

We currently intertwine the KVM PSCI implementation with the general
dispatch of hypercall handling, which makes perfect sense because PSCI
is the only category of hypercalls we support.
However, as we are about to support additional hypercalls, factor out
this functionality into a separate hypercall handler file.

In some scenarios, such as buggy guest or incorrect configuration of the
VMM and firmware description data, userspace will detect a memory access
to a portion of the IPA, which is not mapped to any MMIO region.
For this purpose, the appropriate action is to inject an external abort
to the guest. The kernel already has functionality to inject an
external abort, but we need to wire up a signal from user space that
lets user space tell the kernel to do this.
It turns out, we already have the set event functionality which we can
perfectly reuse for this.

For a long time, if a guest accessed memory outside of a memslot using
any of the load/store instructions in the architecture which doesn't
supply decoding information in the ESR_EL2 (the ISV bit is not set), the
kernel would print the following message and terminate the VM as a
result of returning -ENOSYS to userspace:
load/store instruction decoding not implemented
The reason behind this message is that KVM assumes that all accesses
outside a memslot is an MMIO access which should be handled by
userspace, and we originally expected to eventually implement some sort
of decoding of load/store instructions where the ISV bit was not set.
However, it turns out that many of the instructions which don't provide
decoding information on abort are not safe to use for MMIO accesses, and
the remaining few that would potentially make sense to use on MMIO
accesses, such as those with register writeback, are not used in
practice. It also turns out that fetching an instruction from guest
memory can be a pretty horrible affair, involving stopping all CPUs on
SMP systems, handling multiple corner cases of address translation in
software, and more. It doesn't appear likely that we'll ever implement
this in the kernel.
What is much more common is that a user has misconfigured his/her guest
and is actually not accessing an MMIO region, but just hitting some
random hole in the IPA space. In this scenario, the error message above
is almost misleading and has led to a great deal of confusion over the
years.
It is, nevertheless, ABI to userspace, and we therefore need to
introduce a new capability that userspace explicitly enables to change
behavior.
This patch introduces KVM_CAP_ARM_NISV_TO_USER (NISV meaning Non-ISV)
which does exactly that, and introduces a new exit reason to report the
event to userspace. User space can then emulate an exception to the
guest, restart the guest, suspend the guest, or take any other
appropriate action as per the policy of the running system.

r0-r3 & r12 registers are saved & restored, before & after svc
respectively. Intention was to preserve those registers across thread to
handler mode switch.
On v7-M, hardware saves the register context upon exception in AAPCS
complaint way. Restoring r0-r3 & r12 is done from stack location where
hardware saves it, not from the location on stack where these registers
were saved.
To clarify, on stm32f429 discovery board:
1. before svc, sp - 0x90009ff8
2. r0-r3,r12 saved to 0x90009ff8 - 0x9000a00b
3. upon svc, h/w decrements sp by 32 & pushes registers onto stack
4. after svc, sp - 0x90009fd8
5. r0-r3,r12 restored from 0x90009fd8 - 0x90009feb
Above means r0-r3,r12 is not restored from the location where they are
saved, but since hardware pushes the registers onto stack, the registers
are restored correctly.
Note that during register saving to stack (step 2), it goes past
0x9000a000. And it seems, based on objdump, there are global symbols
residing there, and it perhaps can cause issues on a non-XIP Kernel
(on XIP, data section is setup later).
Based on the analysis above, manually saving registers onto stack is at
best no-op and at worst can cause data section corruption. Hence remove
storing of registers onto stack before svc.

There have been some cases of droid4 battery bulging that seem to be
related to being left connected to the charger for several weeks.
It is suspected that the 4.35V charge voltage configured for the battery
is too much in the long run, so lets limit the charge voltage to 4.2V.
It could also be that the batteries are just getting old.
We don't really want to just change the charge voltage to 4.2V as Android
may have charged the battery to 4.35V as pointed out by Pavel Machek.
To add checks for battery voltage, the driver needs to understand the
voltage it's charging at, and also needs to better understand it's
charger state. Right now it only understands connect and disconnect,
while now we need to know also a connected state but not charging.
So let's add better charger state handling with help of chrgcurr2 interrupt
for detecting charge full and retry, and add a check for battery voltage
before we start charging. And then we finally can lower the charge voltage
to 4.2V.
Note that we've been using the same register values as the Android distros
on droid4, so it is suspected that the same problem also exists in Android.

Looks like the i2c timings in high-speed mode do not work properly to
allow us to clear I2C_DISABLE bits for PRM_VOLTCTRL register and the
device reboots if I2C_DISABLE bits are cleared.
Let's configure the voltage controller i2c for low-speed mode as done in
the Motorola Mapphone Android Linux kernel. This saves us about 7mW of
power during retention compared to the high-speed values.
Let's also change the low-speed warning to pr_info about relying on the
bootloader configured low-speed values like we currently do.

after commit db8918f61d51 ("iommu/omap: streamline enable/disable
through runtime pm callbacks") to enable/disable the clocks properly
and maintain the reference count and the omap_hwmod state machine.
So, add these callbacks through iommu pdata quirks for the OMAP3
ISP IOMMU.

The OMAP IOMMU driver requires the device_enable/idle platform
data ops on all the IOMMU devices to be able to enable and disable
the clocks after commit db8918f61d51 ("iommu/omap: streamline
enable/disable through runtime pm callbacks"). Plug in these
pdata ops for all the existing IOMMUs through pdata quirks to
maintain functionality.

Similar to existing omap3_vc_set_pmic_signaling(), let's add omap4
specific omap4_vc_set_pmic_signaling(). This allows the configured
devices to enable voltage controller for retention later on during
init.

Nothing in mach-mmp/ uses them and they belong to the PHY driver.

Let's move cputype.h away from mach-mmp/ so that the drivers outside that
directory are able to tell the precise silicon revision. The MMP3 USB OTG
PHY driver needs this.

Used to bring up the second core on MMP3.

Similar to MMP2, which this patch is based on. Known differencies from MMP2
are:
* Two PJ4B cores instead of one PJ4
* Tauros 3 L2 cache controller instead of Tauros 2
* A GIC interrupt controller optionally used instead of the MMP one
* A TWD local timer
* Different USB2 PHY
* A USB3 SS controller
* More interrupt muxes
Hard to tell what else is different, because documentation is not
available.

The MMP2 and later includes a system control unit in this area. We'll need
that to initialize the secondary core on MMP3.

MMP3 has a PJ4B with a Tauros 3 cache controller that uses CACHE_L2X0
instead, while CACHE_TAUROS2 is present on PJ4 and PJ1 (Mohawk) based
platforms only.
