2014-06-21regulator: palmas: Fix SMPS enable/disable/is_enabledNishanth Menon1-0/+12
We use regmap regulator ops to enable/disable and check if regulator is enabled for various SMPS. However, these depend on valid enable_reg, enable_mask and enable_value in regulator descriptor. Currently we do not populate these for SMPS other than SMPS10, this results in spurious results as regmap assumes that the values are valid and ends up reading register 0x0 RTC:SECONDS_REG on Palmas variants that do have RTC! To fix this, we update proper parameters for the descriptor fields. Further, we want to ensure the behavior consistent with logic prior to commit dbabd624d4eec50b6, where, once you do a set_mode, enable/disable ensure the logic remains consistent and configures Palmas to the configuration that we set with set_mode (since the configuration register is common). To do this, we can rely on the regulator core's regulator_register behavior where the regulator descriptor pointer provided by the regulator driver is stored. (no reallocation and copy is done). This lets us update the enable_value post registration, to remain consistent with the mode we configure as part of set_mode.

2014-06-05regulator: palmas: Fix SMPS list for 0VNishanth Menon1-0/+2
get_voltage_sel reads from SMPS register - if the read selector value is 0, the SMPS is actually disabled - So, this is in addition to the ctrl_register that may also be used to enable/disable the SMPS. The original logic(prior to commit dbabd624d4eec50b6) used to be: static int palmas_map_voltage_smps(struct regulator_dev *rdev, int min_uV, int max_uV) <snip> if (min_uV == 0) return 0; To handle this scenario, with the transition to regulator_list implementation, we seem to have missed the data necessary to mark as one of the valid entries as "0" 'disabled regulator' which results in 0 volts - So, stick with pre-existing logic. Without this added to the list, palmas regulator driver, on probe, attempts to setup constraints and in the case of OMAP5uEVM, SMPS9 (which is mapped for 2v1 audio supply) fails in regulator_list_voltage_linear_range mapping of '0', and as a fall back of constraints not being applied, the entire regulator list is not enumerated due to assumption that something system wide has gone bad on with the PMIC.

With commit 064d5cd110f94ce41ca5681dcda8b77fa63d5b95 (regulator: core: Fix the init of DT defined fixed regulators) We ensure that regulator must be capable of providing it's current voltage when constraints are used, however adding the return value in the print is a little more informative to explain the nature of the failure involved. So, instead of providing message such as: smps9: failed to get the current voltage having error value added to the message such as: smps9: failed to get the current voltage(-22) is a little more informative for debugging the error.

2014-06-03regulator: as3722: Make 0 a valid selectorThierry Reding1-0/+2
As of commit 064d5cd110f9 (regulator: core: Fix the init of DT defined fixed regulators) the regulator core tries to query the current voltage of a regulator when applying constraints. This exposes a bug in the AS3722 regulator driver which fails to read the voltage of disabled regulators. The reason is that the hardware is programmed to a selector of 0, but none of the voltage tables include 0 as a valid selector. The datasheets indicate that 0 is a valid selector when the regulators are powered off. To fix this, add a range including selector 0 to the voltage tables.

When a regulator is defined using DT and it has a single voltage the regulator init always tries to apply this voltage. However it fails if the regulator isn't settable because it is using an internal low level function. To overcome this we now first query the regulator and only set it if needed.

2014-06-01regulator: core: Disable unused regulators after deferred probing is doneSaravana Kannan1-1/+1
regulator_init_complete does a scan of regulators which dont have always-on or consumers are automatically disabled as being unused. However, with deferred probing, late_initcall() is too soon to declare a regulator as unused as the regulator itself might not have registered due to defferal - Example: A regulator deffered due to i2bus not available which in turn is deffered due to pinctrl availability. Since deferred probing is done in late_initcall(), do the cleanup of unused regulators by regulator_init_complete in late_initcall_sync instead of late_initcall.

2014-06-01regulator: Don't disable unused regulators we don't have permission forMark Brown1-2/+6
In the spirit of conservatism that governs our general approach to permissions it is better if we don't touch regulators we weren't explicitly given permissions to control. This avoids the need to explicitly specify unknown regulators in DT as always on, if a regulator is not otherwise involved in software control it can be omitted from the DT. Regulators explicitly given constraints in DT still need to have an always on constraint specified as before. Signed-off-by: Mark Brown <broonie@linaro.org>
