7 years agoregulator: TPS65910: Fix VDD1/2 voltage selector count

regulator: TPS65910: Fix VDD1/2 voltage selector count

Count of selector voltage is required for regulator_set_voltage
to work via set_voltage_sel. VDD1/2 currently have it as zero,
so regulator_set_voltage won't work for VDD1/2.
Update count (n_voltages) for VDD1/2.

Output Voltage = (step value * 12.5 mV + 562.5 mV) * gain

With above expr, number of voltages that can be selected is
step value count * gain count

constant for gain count will be called VDD1_2_NUM_VOLT_COARSE

existing constant for step value count is VDD1_2_NUM_VOLTS,
use VDD1_2_NUM_VOLT_FINE instead to make clear that step value
is not the only component in deciding selectable voltage count

virtio-pci: fix use after free

Commit 31a3ddda166cda86d2b5111e09ba4bda5239fae6 introduced
a use after free in virtio-pci. The main issue is
that the release method signals removal of the virtio device,
while remove signals removal of the pci device.

For example, on driver removal or hot-unplug,
virtio_pci_release_dev is called before virtio_pci_remove.
We then might get a crash as virtio_pci_remove tries to use the
device freed by virtio_pci_release_dev.

We allocate/free all resources together with the
pci device, so we can leave the release method empty.

Rafael J. Wysocki [Sat, 12 Nov 2011 22:17:27 +0000]
ACPI / cpuidle: Remove acpi_idle_suspend (to fix suspend regression)

After commit e978aa7d7d57 ("cpuidle: Move dev->last_residency update to
driver enter routine; remove dev->last_state") setting acpi_idle_suspend
to 1 by acpi_processor_suspend() causes the ACPI cpuidle routines to
return error codes continuously, which in turn causes cpuidle to lock up
(hard).

However, acpi_idle_suspend doesn't appear to be useful for any
particular purpose (it's racy and doesn't really provide any real
protection), so it can be removed, which makes the problem go away.

7 years agovrtc: change its year offset from 1960 to 1972
Feng Tang [Thu, 10 Nov 2011 13:23:39 +0000]
vrtc: change its year offset from 1960 to 1972

Real world year equals the value in vrtc YEAR register plus an offset.
We used 1960 as the offset to make leap year consistent, but for a
device's first use, its YEAR register is 0 and the system year will
be parsed as 1960 which is not a valid UNIX time and will cause many
applications to fail mysteriously. So we use 1972 instead to fix this
issue.

Updated patch which adds a sanity check suggested by Mathias

This isn't a change in behaviour for systems, because 1972 is the one we
actually use. It's the old version in upstream which is out of sync with
all devices.

7 years agodrm: do not sleep on vblank while holding a mutex
Ilija Hadzic [Mon, 31 Oct 2011 21:46:18 +0000]
drm: do not sleep on vblank while holding a mutex

drm_wait_vblank must be DRM_UNLOCKED because otherwise it
will grab the drm_global_mutex and then go to sleep until the vblank
event it is waiting for. That can wreck havoc in the windowing system
because if one process issues this ioctl, it will block all other
processes for the duration of all vblanks between the current and the
one it is waiting for. In some cases it can block the entire windowing
system.

v2: incorporate comments received from Daniel Vetter and
    Michel Daenzer.

v3/v4: after a lengty discussion with Daniel Vetter, it was concluded
       that the only thing not yet protected with locks and atomic
       ops is the write to dev->last_vblank_wait. It's only used in a
       debug file in proc, and the current code already employs no
       correct locking: the proc file only takes dev->struct_mutex,
       whereas drm_wait_vblank implicitly took the drm_global_mutex.
       Given all this, it's not worth bothering to try to fix
       the locks at this time.

7 years agodrm/radeon: Make sure CS mutex is held across GPU reset.
Michel Dänzer [Thu, 10 Nov 2011 17:57:26 +0000]
drm/radeon: Make sure CS mutex is held across GPU reset.

This was only the case if the GPU reset was triggered from the CS ioctl,
otherwise other processes could happily enter the CS ioctl and wreak havoc
during the GPU reset.

This is a little complicated because the GPU reset can be triggered from the
CS ioctl, in which case we're already holding the mutex, or from other call
paths, in which case we need to lock the mutex. AFAICT the mutex API doesn't
allow recursive locking or finding out the mutex owner, so we need to handle
this with helper functions which allow recursive locking from the same
process.

ARM: mach-shmobile: cpuidle single/global and last_state fixes

The following commits break cpuidle on SH-Mobile ARM:

46bcfad cpuidle: Single/Global registration of idle states
e978aa7 cpuidle: Move dev->last_residency update to driver enter routine; remove dev->last_state

This patch remedies these issues by up-porting the SH-Mobile
code to fit with the above introduced framework changes.

It is worth noting that the new code becomes significantly cleaner,
so these framework changes are very welcome. At the same time this
breakage could probably have been avoided by grepping for "last_state"

Paul Mundt [Fri, 11 Nov 2011 06:41:50 +0000]
drivers: sh: Generalize runtime PM platform stub.

The runtime PM platform support stub in use by ARM-based SH/R-Mobile
platforms contains nothing that's specifically ARM-related and instead of
wholly generic to anything using the clock framework.

The recent runtime PM changes interact rather badly with the lazy
disabling of clocks late in the boot process through the clock framework,
leading to situations where the runtime suspend/resume paths are entered
without a clock being actively driven due to having been lazily gated
off.

In order to correct this we can trivially tie in the aforementioned stub
as a general fallback for all SH platforms that don't presently have
their own runtime PM implementations (the corner case being SH-based
SH-Mobile platforms, which have their own stub through the hwblk API --
which in turn has bitrotted and will be subsequently adapted to use the
same stub as everyone else), regardless of whether the platforms choose
to define power domains of their own or not.

This fixes up regressions for clock framework users who also build in
runtime PM support without any specific power domains of their own, which
was previously causing the serial console to be lost when warring with
lazy clock disabling.

We disabled the check of NO_PRESENCE bit of the default pin-config
in commit f4419172 temporarily.  One problem was that the first
implementation was wrong -- the bit after the shift must be checked.
However, this would still give many regressions on machines with broken
BIOS.  They set this bit wrongly even on active pins.

A workaround is to check whether all pins contain this bit.  As far as
I've checked, broken BIOSen set this bit on all pins, no matter whether
active or not.  In such a case, the driver should ignore this bit check.

ALSA: vmaster - Free slave-links when freeing the master element

When freeing the vmaster master element, we should release slave-links
properly, not only assumig that slaves will be freed soon later.

7 years agoALSA: hda - Don't add elements of other codecs to vmaster slave

ALSA: hda - Don't add elements of other codecs to vmaster slave

When a virtual mater control is created, the driver looks for slave
elements from the assigned card instance.  But this may include the
elements of other codecs when multiple codecs are on the same HD-audio
bus.  This works at the first time, but it'll give Oops when it's once
freed and re-created via reconfig sysfs.

This patch changes the element-look-up strategy to limit only to the
mixer elements of the same codec.

pinctrl: hide subsystem from the populace

Machines that have embedded pin controllers need to select them
explicitly, so why broadcast their config options to menuconfig.
We provide a helpful submenu for those machines that do select
it, making it possible to enable debugging for example.
