2019-04-15regulator: tps6524x: Remove *rdev[N_REGULATORS] from struct tps6524xAxel Lin1-5/+4
Current code is using devm_regulator_register() so we don't need to store *rdev for clean up, use a local variable instead. Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Mark Brown <broonie@kernel.org>

2016-04-20regulator: tps6524x: Fix broken use of spi_dev_get()Mark Brown1-1/+1
The tps6524x driver uses spi_dev_get() to take a copy of the SPI device it uses but has no obvious reason to do so and never calls spi_dev_put() to release the reference. Fix this to just a straight copy. Signed-off-by: Mark Brown <broonie@kernel.org>

2013-04-28regulator: Remove NULL test before calling regulator_unregister()Axel Lin1-2/+1
It's safe to call regulator_unregister() with NULL, thus remove the NULL test before regulator_unregister() calls. Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Mark Brown <broonie@sirena.org.uk>

2012-07-02regulator: tps6524x: Convert fixed ilimsel to table basedAxel Lin1-18/+26
This patch refactors the code to get rid of the fixed_ilimsel and FIXED_ILIMSEL flag usage, and convert all the fixed ilimsel to table based (with one entry in the table). We can differentiate fixed ilimsel by checking info->n_ilimsels == 1, thus FIXED_ILIMSEL flag can be removed. This change makes the logic of the code simpler as all the ilimsels are table based now.

2012-07-02regulator: tps6524x: Convert to regulator_list_voltage_table()Axel Lin1-33/+19
This patch adds fixed_5000000_voltage table for fixed voltage, so we can convert regulator_ops to regulator_list_voltage_table. We can differentiate fixed voltage by checking rdev->desc->n_voltages == 1, thus remove the FIXED_VOLTAGE flag usage.

2012-04-09regulator: core: Use a struct to pass in regulator runtime configurationMark Brown1-2/+6
Rather than adding new arguments to regulator_register() every time we want to add a new bit of dynamic information at runtime change the function to take these via a struct. By doing this we avoid needing to do further changes like the recent addition of device tree support which required each regulator driver to be updated to take an additional parameter. The regulator_desc which should (mostly) be static data is still passed separately as most drivers are able to configure this statically at build time.

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator Pull regulator updates for 3.4 from Mark Brown: "This has been a fairly quiet release from a regulator point of view, the only real framework features added were devm support and a convenience helper for setting up fixed voltage regulators. We also added a couple of drivers (but will drop the BQ240022 driver via the arm-soc tree as it's been replaced by the more generic gpio-regulator driver) and Axel Lin continued his relentless and generally awesome stream of fixes and cleanups." * tag 'regulator-3.4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator: (93 commits) regulator: Fix up a confusing dev_warn when DT lookup fails regulator: Convert tps6507x to set_voltage_sel regulator: Refactor tps6507x to use one tps6507x_pmic_ops for all LDOs and DCDCs regulator: Make s5m8767_get_voltage_register always return correct register regulator: s5m8767: Check pdata->buck[2|3|4]_gpiodvs earlier regulator: tps65910: Provide settling time for DCDC voltage change regulator: Add Anatop regulator driver regulator: Simplify implementation of tps65912_get_voltage_dcdc regulator: Use tps65912_set_voltage_sel for both DCDCx and LDOx regulator: tps65910: Provide settling time for enabling rails regulator: max8925: Use DIV_ROUND_UP macro regulator: tps65912: Use simple equations to get register address regulator: Fix the logic of tps65910_get_mode regulator: Merge tps65217_pmic_ldo234_ops and tps65217_pmic_dcdc_ops to tps65217_pmic_ops regulator: Use DIV_ROUND_CLOSEST in wm8350_isink_get_current regulator: Use array to store dcdc_range settings for tps65912 regulator: Rename s5m8767_convert_voltage to s5m8767_convert_voltage_to_sel regulator: tps6524x: Remove unneeded comment for N_REGULATORS regulator: Rename set_voltage_sel callback function name to *_sel regulator: Fix s5m8767_set_voltage_time_sel calculation value ...

2011-11-23regulator: pass additional of_node to regulator_register()Rajendra Nayak1-1/+1
With device tree support for regulators, its needed that the regulator_dev->dev device has the right of_node attached. To be able to do this add an additional parameter to the regulator_register() api, wherein the dt-adapted driver can then pass this additional info onto the regulator core.

2011-03-26regulator: fix tps6524x section mismatchRandy Dunlap1-1/+1
Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Fix section mismatch that is caused by init code calling exit code: pmic_remove() cannot be marked as __devexit. WARNING: drivers/regulator/tps6524x-regulator.o(.devinit.text+0x205): Section mismatch in reference from the function pmic_probe() to the function .devexit.text:pmic_remove() The function __devinit pmic_probe() references a function __devexit pmic_remove(). This is often seen when error handling in the init function uses functionality in the exit path. The fix is often to remove the __devexit annotation of pmic_remove() so it may be used outside an exit section.
