usb: gadget: android: Honor CONFIG_USB_GADGET_VBUS_DRAW

The maximum current draw was hard coded to 500 mA.  composite.c
has code that uses CONFIG_USB_GADGET_VBUS_DRAW to set the
bMaxPower and to set whether or not the device is self-powered if
they haven't been set.  This change removes the code in android.c

Marc Zyngier [Fri, 10 Feb 2012 10:50:26 +0000]
smp_twd: make sure timer is stopped before registering it

On secondary CPUs, the Timer Control Register is not reset
to a sane value before the timer is registered, and the TRM
doesn't seem to indicate any reset value either. In some cases,
the kernel will take an interrupt too early, depending on what
junk was present in the registers at reset time.

The fix is to set the Timer Control Register to 0 before
registering the clock_event_device and enabling the interrupt.

Problem seen on VE (Cortex A5) and Tegra.

regmap: Bypassing cache when initializing cache

During regcache_init, if client has not passed the
default data of cached register then it is directly
read from the hw to initialize cache. This hw register
read happens before cache ops are initialized and hence
avoiding register read to check for the data available

7 years agoregmap: Fix cache defaults initialization from raw cache defaults
Lars-Peter Clausen [Wed, 15 Feb 2012 09:23:25 +0000]
regmap: Fix cache defaults initialization from raw cache defaults

Currently registers with a value of 0 are ignored when initializing the register
defaults from raw defaults. This worked in the past, because registers without a
explicit default were assumed to have a default value of 0. This was changed in
commit b03622a8 ("regmap: Ensure rbtree syncs registers set to zero properly").
As a result registers, which have a raw default value of 0 are now assumed to
have no default. This again can result in unnecessary writes when syncing the
cache. It will also result in unnecessary reads for e.g. the first update
operation. In the case where readback is not possible this will even let the
update operation fail, if the register has not been written to before.

So this patch removes the check. Instead it adds a check to ignore raw defaults
for registers which are volatile, since those registers are not cached.

7 years agoregmap: Don't use bitfields for booleans

regmap: Don't use bitfields for booleans

This was a cut'n'paste from some older code.

Since we're about to add debugfs support don't do the obvious thing and
use bool, use u32 instead (which debugfs has been using since time
immemorial).

regmap: if format_write is used, declare all registers as "unreadable"

Using .format_write means, we have a custom function to write to the
chip, but not to read back. Also, mark registers as "not precious" and
"not volatile" which is implicit because we cannot read them. Make those

7 years agoregmap: Support register patch sets
Mark Brown [Sat, 21 Jan 2012 12:01:14 +0000]
regmap: Support register patch sets

Device manufacturers frequently provide register sequences, usually not
fully documented, to be run at startup in order to provide better defaults
for devices (for example, improving performance in the light of silicon
evaluation). Support such updates by allowing drivers to register update
sets with the core. These updates will be written to the device immediately
and will also be rewritten when the cache is synced.

The assumption is that the reason for resyncing the cache will always be
that the device has been powered off. If this turns out to not be the case
then a separate operation can be provided.

Currently the implementation only allows a single set of updates to be
specified for a device, this could be extended in future.

7 years agoregmap: Reset cache status when reinitialsing the cache
Mark Brown [Fri, 20 Jan 2012 13:39:37 +0000]
regmap: Reset cache status when reinitialsing the cache

When we reinitialise the cache make sure that we reset the cache access
flags, ensuring that the reinitialised cache is in the default state
which is what callers would and do expect given the function name.

This is particularly likely to cause issues in systems where there was no
cache previously as those systems have cache bypass enabled, as for the
wm8994 driver where this was noticed.
