soc/tegra: Changes for v5.2-rc1
Besides a couple of fixes to better cope with deferred probing, this set
of patches also implements the acquire/release protocol for resets used
during powergate operations. This is necessary to allow these resets to
be temporarily shared with other devices that may also need to control
these resets.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into arm/drivers
PM changes for am335x and am437x
This series adds support for am437x RTC-only mode in suspend. In the
RTC-only mode suspend, everything is shut down except the RTC. This
makes the power consumption very low for suspend mode.
To support RTC-only mode, we need to export omap_rtc_power_off_program()
from the rtc driver and improve PM code to save and restore the wkup
domain context. As RTC-only mode depends on the device being wired
properly for things like memory, we need to also check for the machine
type before we allow it. We also need to run DDR3 hardware leveling on
resume.
Note that there is a trivial merge conflict between the RTC branch
and these changes where the RTC branch makes tm2bcd() a void function
and the error handling parts can be just dropped.

Commit 8df127456f29 ("soc/tegra: pmc: Enable XUSB partitions on boot")
was added as a workaround to ensure that the XUSB powergates or domains
were turned on early during boot because as this time the Tegra XHCI
driver did not handle the power domains at all. Now that the Tegra XHCI
driver has been updated to properly managed the power domains, the
workaround to enable the XUSB power domain early has been removed. This
also means that we can now move the initialisation of the powergates
into the PMC driver probe. Therefore, move the powergate initialisation
into the PMC driver probe and return any errors detected. To handle any
errors, functions to cleanup and remove any power-domains registered
with the generic power-domain framework have been added.
Finally the initialisation of the 'powergates_available' bitmask is kept
in the PMC early init function to allow the legacy PMC powergate APIs to
be called during early boot for enabling secondary CPUs on 32-bit Tegra
devices.

Commit 5f84bb1a4099 ("soc/tegra: pmc: Add sysfs entries for reset info")
added sysfs entries for Tegra reset source and level. However, these
sysfs are not removed on error and so if the registering of PMC device
is probe deferred, then the next time we attempt to probe the PMC device
warnings such as the following will be displayed on boot ...
sysfs: cannot create duplicate filename '/devices/platform/7000e400.pmc/reset_reason'
Fix this by calling device_remove_file() for each sysfs entry added on
failure. Note that we call device_remove_file() unconditionally without
checking if the sysfs entry was created in the first place, but this
should be OK because kernfs_remove_by_name_ns() will fail silently.

Commit 5f84bb1a4099 ("soc/tegra: pmc: Add sysfs entries for reset info")
added support for reading the Tegra reset source and level from sysfs.
However, there are a few issues with this commit which are ...
1. The number of reset sources for Tegra210 is defined as 5 but it
should be 6.
2. The number of reset sources for Tegra186 is defined as 13 but it
should be 15.
3. The SoC data variables num_reset_sources and num_reset_levels are
defined but never used.
Fix the above by ...
1. Removing the reset source 'AOTAG' from the tegra30_reset_sources
because this is only applicable for Tegra210.
2. Adding a new tegra210_reset_sources structure for Tegra210 reset
sources.
3. Correct the number of reset sources for Tegra210 and Tegra186 by
using the ARRAY_SIZE macro.
4. Updating the functions reset_reason_show() and reset_level_show()
to check whether the value read is valid. While we are at it
clean-up these functions to remove an unnecessary u32 variable.

of_device_get_match_data()
of_match_device can return NULL if no matching device is found though
it's highly unlikely to happen in scmi_probe as it's called only if
a valid match is found.
However we can use of_device_get_match_data() instead of
of_match_device()->data to handle NULL pointer checks and return -EINVAL
in such a scenario.

of_parse_phandle_with_args() requires the caller to call of_node_put() on

However, in this case, since we don't actually use the returned pointer,
we can simply pass in NULL.

When returning from DeepSleep mode on AM437x platforms the EMIF must run
DDR hardware leveling, same as done during u-boot, to properly restore the
EMIF PHY to it's operational state on platforms using DDR3.
Call the ti-emif-sram-pm run_hw_leveling routine to perform this. This
happens after all other EMIF values are restored so the exact same
configuration used at boot is used at the end of EMIF resume as well.

In certain situations, such as when returning from low power modes, the
EMIF must re-run hardware leveling to properly restore DDR3 access.
This is accomplished by introducing a new ti-emif-sram-pm call,
ti_emif_run_hw_leveling, to check if DDR3 is in use and if so, trigger
the full write and read leveling processes.

During RTC-only suspend, power is lost to the wkup domain, so we need to
save and restore the state of that domain. We also need to store some
information within the RTC registers so that u-boot can do the right thing
at powerup.
The state is entered by getting the RTC to bring the pmic_power_en line low
which will instruct the PMIC to disable the appropriate power rails after
putting DDR into self-refresh mode. To bring pmic_power_en low, we need to
get an ALARM2 event. Since we are running from SRAM at that point, it means
calculating what the next second is (via ASM) and programming that into the
RTC. This patch also adds support for wake up source detection.

Prepare rtc driver for rtc-only with DDR in self-refresh mode.
omap_rtc_power_off now should cater to two features:
1) RTC plus DDR in self-refresh is power a saving mode where in the
entire system including the different voltage rails from PMIC are
shutdown except the ones feeding on to RTC and DDR. DDR is kept in
self-refresh hence the contents are preserved. RTC ALARM2 is connected
to PMIC_EN line once we the ALARM2 is triggered we enter the mode with
DDR in self-refresh and RTC Ticking. After a predetermined time an RTC
ALARM1 triggers waking up the system[1]. The control goes to bootloader.
The bootloader then checks RTC scratchpad registers to confirm it was an
rtc_only wakeup and follows a different path, configure bare minimal
clocks for ddr and then jumps to the resume address in another RTC
scratchpad registers and transfers the control to Kernel. Kernel then
restores the saved context. omap_rtc_power_off_program does the ALARM2
programming part.
[1] http://www.ti.com/lit/ug/spruhl7h/spruhl7h.pdf Page 2884
2) Power-off: This is usual poweroff mode. omap_rtc_power_off calls the
above omap_rtc_power_off_program function and in addition to that
programs the OMAP_RTC_PMIC_REG for any external wake ups for PMIC like
the pushbutton and shuts off the PMIC.
Hence the split in omap_rtc_power_off.

If userspace doesn't end the input with a newline (which can easily
happen if the write happens from a C program that does write(fd,
iface, strlen(iface))), we may end up including garbage from a
previous, longer value in the device_name. For example
# cat device_name
# printf 'eth12' > device_name
# cat device_name
eth12
# printf 'eth3' > device_name
# cat device_name
eth32
I highly doubt anybody is relying on this behaviour, so switch to
simply copying the bytes (we've already checked that size is <
IFNAMSIZ) and unconditionally zero-terminate it; of course, we also
still have to strip a trailing newline.
This is also preparation for future patches.

decoding the guaranteed performance register information and make
the intel_pstate driver to fall back to the nominal frequency when
reporting the base frequency if the guaranteed performance register
information is not there (Srinivas Pandruvada).

git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull IOMMU fixes from Joerg Roedel:
- Fix a bug in the AMD IOMMU driver not handling exclusion ranges
correctly. In fact the driver did not reserve these ranges for IOVA
allocations, so that dma-handles could be allocated in an exclusion
range, leading to data corruption. Exclusion ranges have not been
used by any firmware up to now, so this issue remained undiscovered
for quite some time.
- Fix wrong warning messages that the IOMMU core code prints when it
tries to allocate the default domain for an iommu group and the
driver does not support any of the default domain types (like Intel
VT-d).
* tag 'iommu-fixes-v5.1-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu:

Pull char/misc driver fixes from Greg KH:
"Here are some binder, habanalabs, and vboxguest driver fixes for
5.1-rc3.
The Binder fixes resolve some reported issues found by testing, first
by the selinux developers, and then earlier today by syzbot.
The habanalabs fixes are all minor, resolving a number of tiny things.
The vboxguest patches are a bit larger. They resolve the fact that
virtual box decided to change their api in their latest release in a
way that broke the existing kernel code, despite saying that they were
never going to do that. So this is a bit of a "new feature", but is
good to get merged so that 5.1 will work with the latest release. The
changes are not large and of course virtual box "swears" they will not
break this again, but no one is holding their breath here.
All of these have been in linux-next for a while with no reported
issues"

"The important fixes at this time are a couple fixes in ALSA core: a
fix for PCM is about the OOB access in PCM OSS plugins that has been

switching to kvmalloc(). Another fix is for a long-standing PCM
problem wrt racy PM resume.
