regulator: s2mps11: fix incorrect register for buck10

2013-02-14T18:47:59Z

commit c76edd52bf19c9d01da7edc4ff04d3707c299779 upstream. For BUCK10 the control registers are wrongly set as buck9 control register This patch corrects the control registers for buck10 Signed-off-by: Alim Akhtar Signed-off-by: Mark Brown Signed-off-by: Greg Kroah-Hartman

regulator: clear state each invocation of of_regulator_match

2013-02-14T18:47:59Z

commit a2f95c363701deba2205f81929b40222ea6f4f80 upstream. of_regulator_match() saves some dynamcially allocated state into the match table that's passed to it. By implementation and not contract, for each match table entry, if non-NULL state is already present, of_regulator_match() will not overwrite it. of_regulator_match() is typically called each time a regulator is probe()d. This means it is called with the same match table over and over again if a regulator triggers deferred probe. This results in stale, kfree()d data being left in the match table from probe to probe, which causes a variety of crashes or use of invalid data. Explicitly free all output state from of_regulator_match() before generating new results in order to avoid this.

regulator: max8998: fix incorrect min_uV value for ldo10

2013-02-14T18:47:59Z

commit 36a6f8c035760dcbd0c3acb4c2fd56268588a9cb upstream. Correct value for minimal voltage for ldo10 output is 950000 uV. This patch fixes the typo introduced by patch adf6178ad5552a7f2f742a8c85343c50 ("regulator: max8998: Use uV in voltage_map_desc"), what solves broken probe of max8998 in v3.8-rc4.

regulator: max8998: Ensure enough delay time for max8998_set_voltage_buck_time_sel

2013-01-17T16:46:39Z

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 Signed-off-by: Greg Kroah-Hartman

regulator: max8998: Use uV in voltage_map_desc

2013-01-17T16:46:39Z

commit adf6178ad5552a7f2f742a8c85343c50f080c412 upstream. Integer division may truncate. This happens when pdata->buckx_voltagex setting is not align with 1000 uV. Thus use uV in voltage_map_desc, this ensures the selected voltage won't less than pdata buckx_voltagex settings. Signed-off-by: Axel Lin Signed-off-by: Mark Brown Signed-off-by: Greg Kroah-Hartman

regulator: max8997: Use uV in voltage_map_desc

2013-01-17T16:46:39Z

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. Signed-off-by: Axel Lin Signed-off-by: Mark Brown Signed-off-by: Greg Kroah-Hartman

regulator: s2mps11: Fix ramp delay value shift operation

2013-01-17T16:45:56Z

commit f7ebaaeb0b4b97b20c1816f11884e7bfe610a2fa upstream. This patch fix the abnormal ramp delay setting. The shift operation was wrong. Signed-off-by: Sangbeom Kim Signed-off-by: Mark Brown Signed-off-by: Greg Kroah-Hartman

regulator: fix voltage check in regulator_is_supported_voltage()

2012-11-15T02:14:18Z

regulator_is_supported_voltage() should return true only if the voltage of fixed/constant regulator is between min_uV and max_uV. Signed-off-by: Marek Szyprowski Signed-off-by: Mark Brown Cc: stable@vger.kernel.org
