2016-01-07regulator: core: remove some dead codeDan Carpenter1-8/+3
Originally queue_delayed_work() used to negative error codes or 0 and 1 on success depending if the work was queued or not. It caused a lot of bugs where people treated all non-zero returns as failures so we changed it to return bool instead in d4283e937861 ('workqueue: make queueing functions return bool'). Now it never returns failure. Checking for negative values causes a static checker warning since it is impossible based on the bool type.

2015-12-18regulator: mt6311: Use REGCACHE_RBTREEDaniel Kurtz1-0/+1
This regulator is on a slow i2c bus. Register accesses are very simple, they all either enable/disable a regulator channel, or select a new voltage level. Thus, reading registers from the device will always return what was last written. Therefore we can save a lot of time when reading registers by using a regmap_cache. Since the register map is relatively large, but we only ever access a few of them, we use an RBTREE cache.

2015-12-02regulator: core: Fix nested locking of suppliesThierry Reding1-2/+9
Commit fa731ac7ea04 ("regulator: core: avoid unused variable warning") introduced a subtle change in how supplies are locked. Where previously code was always locking the regulator of the current iteration, the new implementation only locks the regulator if it has a supply. For any given power tree that means that the root will never get locked. On the other hand the regulator_unlock_supply() will still release all the locks, which in turn causes the lock debugging code to warn about a mutex being unlocked which wasn't locked.

As noticed by Geert Uytterhoeven, my patch to avoid a harmless build warning in regulator_lock_supply() was total crap and introduced a real bug: > [ BUG: bad unlock balance detected! ] > kworker/u4:0/6 is trying to release lock (&rdev->mutex) at: > [<c0247b84>] regulator_set_voltage+0x38/0x50 we still lock the regulator supplies, but not the actual regulators, so we are missing a lock, and the unlock is unbalanced. This rectifies it by first locking the regulator device itself before using the same loop as before to lock its supplies.

2015-11-24mfd: sec-core: Rename MFD and regulator names differentlyAlim Akhtar1-4/+4
Currently S2MPSXX multifunction device is named as *-pmic, and these MFDs also supports regulator as a one of its MFD cell which has the same name, because current name is confusing and we want to sort it out. We did discussed different approaches about how the MFD and it cells need to be named here [1]. Based in the discussion this patch rename MFD regulator name as *-regulator instead of current *-pmic. This patch also changes the corresponding entries in the regulator driver to keep git-bisect happy.

2015-11-20regulator: core: avoid unused variable warningArnd Bergmann1-11/+3
The second argument of the mutex_lock_nested() helper is only evaluated if CONFIG_DEBUG_LOCK_ALLOC is set. Otherwise we get this build warning for the new regulator_lock_supply function: drivers/regulator/core.c: In function 'regulator_lock_supply': drivers/regulator/core.c:142:6: warning: unused variable 'i' [-Wunused-variable] To avoid the warning, this restructures the code to make it both simpler and to move the 'i++' outside of the mutex_lock_nested call, where it is now always used and the variable is not flagged as unused. We had some discussion about changing mutex_lock_nested to an inline function, which would make the code do the right thing here, but in the end decided against it, in order to guarantee that mutex_lock_nested() does not introduced overhead without CONFIG_DEBUG_LOCK_ALLOC.
