2020-08-23treewide: Use fallthrough pseudo-keywordGustavo A. R. Silva
Replace the existing /* fall through */ comments and its variants with the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary fall-through markings when it is the case.

2019-08-09regulator: twl6030: workaround the VMMC reset behaviorGregory CLEMENT
During reset the VMMC regulator doesn't reach 0V and only drops to 1.8V, furthermore the pulse width is under 200us whereas the SD specification expect 1ms. The WR_S bit allows the TWL6030 to no reset at all the VMMC during warm reset and keep the current voltage. Thanks to this workaround the SD card doesn't reach a undefined reset stage. Actually this behavior is available for all the LDO regulator, so the driver will also allow to use it with any of these regulator.

<= 1350000 It has been pointed out to me that the range for vsel = 58 is actually dead code as this is covered by an earlier check for (min_uV >= 700000) && (min_uV <= 1420000) so remove that check completely.

The range min_uV > 1350000 && min_uV <= 150000 is never reachable because of a typo in the previous range check and hence vsel = 59 is never reached. Fix the previous range check to enable the vsel = 59 setting.

2016-11-16regulator: twl: split twl6030 logic into its own fileNicolae Rosia
In order to not break existing users, we keep using the same CONFIG symbol. This makes it easier to add support for TWL6032 and refactor mfd/twl-core. Checkpatch warnings are inherited from twl-regulator.c and will be addressed in a subsequent patch.
