2014-09-10regulator: of: Provide simplified DT parsing methodMark Brown
Currently regulator drivers which support DT all repeat very similar code to supply a list of known regulator identifiers to be matched with DT, convert that to platform data which is then matched up with the regulators as they are registered. This is both fiddly to get right and for devices which can use the standard helpers to provide their operations is the main source of code in the driver. Since this code is essentially identical for most drivers we can factor it out into the core, moving the identifiers in the match table into the regulator descriptors and also allowing drivers to pass in the name of the subnode to search. When a driver provides an of_match string for the regulator the core will attempt to use that to obtain init_data, allowing the driver to remove all explicit code for DT parsing and simply provide data instead. The current code leaks the phandles for the child nodes, this will be addressed incrementally and makes no practical difference for FDT anyway as the DT data structures are never freed.

2014-09-10regulator: remove unnecessary of_node_get() to parentGuodong Xu
These of_node_get() were added to balance refcount decrements inside of of_find_node_by_name(). See: commit c92f5dd2c42f ("regulator: Add missing of_node_put()") However of_find_node_by_name() was then replaced by of_get_child_by_name(), which doesn't call of_node_put() against its input parameter. So, need to remove these unnecessary of_node_get() calls. Signed-off-by: Guodong Xu <guodong.xu@linaro.org> Reviewed-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Mark Brown <broonie@kernel.org>

Also clean up AS3711_REG macro to remove _vshift, _min_uV and _max_uV arguments. _vshift is always 0, so remove it. _min_uV and _max_uV are not required, all required settings are set in REGULATOR_LINEAR_RANGE macro.

But if a regulator is disabled and the system warm restarted, the hardware reports OFF as the opmode so the regulator is not enabled.

2014-08-16regulator: add driver for hi6421 voltage regulatorGuodong Xu
Add driver support for HiSilicon Hi6421 voltage regulators. Two rules for regulator enabling are defined in hi6421 spec: 1) Between disable and enable of each regulator (LDOs or BUCKs), there must be a protection gap. Use @off_on_delay of regulator core to implement this. 2) No two regulators can be enabled at the same time. Use mutex in hi6421_regulator_pdata to ensure this. A protection gap of 100us is added into each LDO/BUCK's .enable_time. Signed-off-by: Guodong Xu <guodong.xu@linaro.org> Signed-off-by: Mark Brown <broonie@linaro.org>
2014-08-16regulator: core: add guard delay between calling regulator_disable and _enableGuodong Xu
Some regulator require a minimum delay between its disable and next enable. This is to avoid damages when out-of-range frequent disable/enable of a single regulator can bring to the regulator chip. Add @off_on_delay to struct regulator_desc. Device drivers' can use this field to set this guard time. Add @last_off_jiffy to struct regulator_dev. When @off_on_delay is set by driver, regulator core can store its last off (disable) time into this field.

This patch makes the regulator description macro take minimum and steps voltage as parameter. In this way many repeated macros can be removed. Now these macros are repeated only if the the LDO/BUCK ctrl registers have non-linear positions. The good thing is these ctrl registers are mostly linear so they are not passed as parameters.
