regulator: core: fix constraints output buffer

2015-08-12T14:33:14Z

commit a7068e3932eee8268c4ce4e080a338ee7b8a27bf upstream. The buffer for condtraints debug isn't big enough to hold the output in all cases. So fix this issue by increasing the buffer. Signed-off-by: Stefan Wahren Signed-off-by: Mark Brown Signed-off-by: Ben Hutchings

regulator: core: fix race condition in regulator_put()

2015-02-20T00:49:35Z

commit 83b0302d347a49f951e904184afe57ac3723476e upstream. The regulator framework maintains a list of consumer regulators for a regulator device and protects it from concurrent access using the regulator device's mutex lock. In the case of regulator_put() the consumer is removed and regulator device's parameters are updated without holding the regulator device's mutex. This would lead to a race condition between the regulator_put() and any function which traverses the consumer list or modifies regulator device's parameters. Fix this race condition by holding the regulator device's mutex in case of regulator_put.

regulator: max8998: Ensure enough delay time for max8998_set_voltage_buck_time_sel

2013-02-06T04:33:28Z

commit 81d0a6ae7befb24c06f4aa4856af7f8d1f612171 upstream. Use DIV_ROUND_UP to prevent truncation by integer division issue. This ensures we return enough delay time. Signed-off-by: Axel Lin Signed-off-by: Mark Brown [bwh: Backported to 3.2: delay is done by driver, not returned to the caller] Signed-off-by: Ben Hutchings

regulator: max8997: Use uV in voltage_map_desc

2013-02-06T04:33:26Z

commit bc3b7756b5ff66828acf7bc24f148d28b8d61108 upstream. Current code does integer division (min_vol = min_uV / 1000) before pass min_vol to max8997_get_voltage_proper_val(). So it is possible min_vol is truncated to a smaller value. For example, if the request min_uV is 800900 for ldo. min_vol = 800900 / 1000 = 800 (mV) Then max8997_get_voltage_proper_val returns 800 mV for this case which is lower than the requested voltage. Use uV rather than mV in voltage_map_desc to prevent truncation by integer division.

regulator: wm831x: Set the new rather than old value for DVS VSEL

regulator: core: Release regulator-regulator supplies on error

2012-05-30T23:43:26Z

commit e81dba85c6388dfabcb76cbc2b8bd02836a53ae5 upstream. If we fail while registering a regulator make sure we release the supply for the regulator if there is one. Signed-off-by: Mark Brown Acked-by: Liam Girdwood Signed-off-by: Ben Hutchings

regulator: Fix the logic to ensure new voltage setting in valid range

2012-05-20T21:56:29Z

commit f55205f4d4a8823a11bb8b37ef2ecbd78fb09463 upstream. I think this is a typo. To ensure new voltage setting won't greater than desc->max, the equation should be desc->min + desc->step * new_val <= desc->max. Signed-off-by: Axel Lin Signed-off-by: Mark Brown Signed-off-by: Ben Hutchings

regulator: Fix setting selector in tps6524x set_voltage function

2012-03-19T16:02:34Z

commit f03570cf1709397ebe656608266b44ec772960c2 upstream. Don't assign the voltage to selector. Signed-off-by: Axel Lin Signed-off-by: Mark Brown Signed-off-by: Greg Kroah-Hartman

regulator: twl: fix twl4030 support for smps regulators

2011-11-28T18:58:31Z

SMPS regulator voltage control differs from the one of the LDO ones. Current TWL code was using LDO regulator ops for controlling the SMPS regulators, which fails. This was fixed fixed by adding separate regulator type which uses correct logic and calculations for the voltage levels. Signed-off-by: Tero Kristo Signed-off-by: Mark Brown Cc: stable@kernel.org
