* pm-cpuidle:
cpuidle: powernv/pseries: Auto-promotion of snooze to deeper idle state
|
|
The idle cpus which stay in snooze for a long period can degrade the
perfomance of the sibling cpus. If the cpu stays in snooze for more
than target residency of the next available idle state, then exit from
snooze. This gives a chance to the cpuidle governor to re-evaluate the
last idle state of the cpu to promote it to deeper idle states.

Commit f61bf13b6a07 ("[media] vb2: add allow_zero_bytesused flag to the
vb2_queue struct") added a WARN_ONCE to catch usage of a deprecated API
using a zero value for v4l2_buffer.bytesused.
However, the condition is checked incorrectly, as the v4L2_buffer
bytesused field is supposed to be ignored for multiplanar buffers. This
results in spurious warnings when using the multiplanar API.
Fix it by checking v4l2_buffer.bytesused for uniplanar buffers and
v4l2_plane.bytesused for multiplanar buffers.
Fixes: f61bf13b6a07 ("[media] vb2: add allow_zero_bytesused flag to the vb2_queue struct")

The enable field needs to be kept in sync with the mode_blob field. Call
drm_atomic_set_mode_prop_for_crtc() instead of setting enable to false
in order to dereference the mode blob correctly.
v2:
- Check the return value of drm_atomic_set_mode_prop_for_crtc()
- Drop the num_connectors local variable

Using -1 as platform device id means that the platform driver core will not
assign any id to the device (the device name will not have id at all). This
results problems on systems that have multiple PCHs (Platform Controller
HUBs) because all of them also include their own copy of LPC device.
All the subsequent device creations will fail because there already exists
platform device with the same name.
Fix this by passing PLATFORM_DEVID_AUTO as platform device id. This makes
the platform device core to allocate new ids automatically.

Add MFD support for the DA9063 OnKey driver
The function da9063_clear_fault_log() is added to mitigate the case of a
hardware power-cut after a long-long OnKey press. Although there is no
software intervention in this case (by definition) such a shutdown would
cause persistent information within the DA9063 FAULT_LOG that would be
available during the next device restart.
Clearance of this persistent register must be completed after such a
hardware power-cut operation has happened so that the FAULT_LOG does not
continue with previous values. The clearance function has been added here
in the kernel driver because wiping the fault-log cannot be counted on
outside the Linux kernel.

Current code in mfd-core calls into ACPI to check resources even
on a system that booted with a DT (on kernels with both DT and ACPI
support compiled in). This triggers ACPI exceptions since we may
end up calling the ACPI interpreter when it has not been initialized:
"ACPI Exception: AE_BAD_PARAMETER, Thread 2064154624 could not acquire
Mutex [0x1] (20150410/utmutex-285)"
This patch fixes the issues by adding a check for an ACPI companion
device before carrying out ACPI resources checks to avoid calling
the ACPI interpreter if the fwnode representing the device is an OF one.

Allow the chip to completely power off if we enter runtime suspend and
there is no jack detection active. This is helpful for systems where
system suspend might remove the supplies to the CODEC, without informing
us. Note the powering off is done in runtime suspend rather than system
suspend, because we need to hold reset until the first time DCVDD is
powered anyway (which would be in runtime resume), and we might as well
save the extra power.

The wm5102 uses a custom boot sequence and the standard boot sequence is
disabled. However, the standard boot sequence must be run at least once
after a cold boot (caused by either a hard reset or removal of AVDD).
Unfortunately the register WRITE_SEQUENCER_CTRL_3 is not affected by the
hardware reset. This means if the device has been previously booted but
the AVDD supply has never been removed, arizona_dev_init will reset the
chip but the boot sequence will not run, which can cause numerous
problems. The solution is to manually clear this register and then boot
the chip again, which is what this patch does.

The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is
not enabled. Hence drivers that depend on GPIOLIB, but use GPIO consumer
functionality only, can still be compiled if GPIOLIB is not enabled.
Relax the dependency on GPIOLIB if COMPILE_TEST is enabled, where
appropriate.

I noticed the PMIC configuration on 37xx-evm won't actually shut down
the voltages during off-idle. Turns out 37xx-evm needs the AC charger
state transitions disabled like we are doing for SDP and LDP in the
legacy booting case.
Let's fix this for device tree based booting by setting up the quirk
flag based on the compatible flag. And let's also use the existing
define for STARTON_CHG.
Note that SDP and EVM do not have the PMIC clken wired to gate the
the oscillator while LDP has.
