Pull regulator fixes from Mark Brown: "There are a few core fixes here around error handling and handling if suspend mode configuration and some driver specific fixes here but the most important change is the fix to the fixed-regulator DT schema conversion introduced during the last merge window. That fixes one of the last two errors preventing successful execution of "make dt_binding_check" which will be enormously helpful for DT schema development" * tag 'regulator-fix-v5.4-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator: regulator: qcom-rpmh: Fix PMIC5 BoB min voltage regulator: pfuze100-regulator: Variable "val" in pfuze100_regulator_probe() could be uninitialized regulator: lochnagar: Add on_off_delay for VDDCORE regulator: ti-abb: Fix timeout in ti_abb_wait_txdone/ti_abb_clear_all_txdone regulator: da9062: fix suspend_enable/disable preparation dt-bindings: fixed-regulator: fix compatible enum regulator: fixed: Prevent NULL pointer dereference when !CONFIG_OF regulator: core: make regulator_register() EPROBE_DEFER aware regulator: of: fix suspend-min/max-voltage parsing

regulator: pfuze100-regulator: Variable "val" in pfuze100_regulator_probe() could be uninitialized

2019-10-01T17:36:42Z

In function pfuze100_regulator_probe(), variable "val" could be initialized if regmap_read() fails. However, "val" is used to decide the control flow later in the if statement, which is potentially unsafe.

regulator: lochnagar: Add on_off_delay for VDDCORE

2019-10-01T16:46:01Z

The VDDCORE regulator takes a good length of time to discharge down, so add an on_off_delay to ensure DCVDD is removed before it is powered on again. Signed-off-by: Charles Keepax Link: https://lore.kernel.org/r/20191001132017.1785-1-ckeepax@opensource.cirrus.com Signed-off-by: Mark Brown

regulator: ti-abb: Fix timeout in ti_abb_wait_txdone/ti_abb_clear_all_txdone

2019-10-01T11:21:02Z

ti_abb_wait_txdone() may return -ETIMEDOUT when ti_abb_check_txdone() returns true in the latest iteration of the while loop because the timeout value is abb->settling_time + 1. Similarly, ti_abb_clear_all_txdone() may return -ETIMEDOUT when ti_abb_check_txdone() returns false in the latest iteration of the while loop. Fix it.

regulator: da9062: fix suspend_enable/disable preparation

2019-09-23T21:21:05Z

Currently the suspend reg_field maps to the pmic voltage selection bits and is used during suspend_enabe/disable() and during get_mode(). This seems to be wrong for both use cases. Use case one (suspend_enabe/disable): Those callbacks are used to mark a regulator device as enabled/disabled during suspend. Marking the regulator enabled during suspend is done by the LDOx_CONF/BUCKx_CONF bit within the LDOx_CONT/BUCKx_CONT registers. Setting this bit tells the DA9062 PMIC state machine to keep the regulator on in POWERDOWN mode and switch to suspend voltage. Use case two (get_mode): The get_mode callback is used to retrieve the active mode state. Since the regulator-setting-A is used for the active state and regulator-setting-B for the suspend state there is no need to check which regulator setting is active.

regulator: fixed: Prevent NULL pointer dereference when !CONFIG_OF

2019-09-23T21:19:52Z

Use of_device_get_match_data which has NULL test for match before dereference match->data. Add NULL test for drvtype so it still works for fixed_voltage_ops when !CONFIG_OF.

Pull LED updates from Jacek Anaszewski: "In this cycle we've finally managed to contribute the patch set sorting out LED naming issues. Besides that there are many changes scattered among various LED class drivers and triggers. LED naming related improvements: - add new 'function' and 'color' fwnode properties and deprecate 'label' property which has been frequently abused for conveying vendor specific names that have been available in sysfs anyway - introduce a set of standard LED_FUNCTION* definitions - introduce a set of standard LED_COLOR_ID* definitions - add a new {devm_}led_classdev_register_ext() API with the capability of automatic LED name composition basing on the properties available in the passed fwnode; the function is backwards compatible in a sense that it uses 'label' data, if present in the fwnode, for creating LED name - add tools/leds/get_led_device_info.sh script for retrieving LED vendor, product and bus names, if applicable; it also performs basic validation of an LED name - update following drivers and their DT bindings to use the new LED registration API: - leds-an30259a, leds-gpio, leds-as3645a, leds-aat1290, leds-cr0014114, leds-lm3601x, leds-lm3692x, leds-lp8860, leds-lt3593, leds-sc27xx-blt Other LED class improvements: - replace {devm_}led_classdev_register() macros with inlines - allow to call led_classdev_unregister() unconditionally - switch to use fwnode instead of be stuck with OF one LED triggers improvements: - led-triggers: - fix dereferencing of null pointer - fix a memory leak bug - ledtrig-gpio: - GPIO 0 is valid Drop superseeded apu2/3 support from leds-apu since for apu2+ a newer, more complete driver exists, based on a generic driver for the AMD SOCs gpio-controller, supporting LEDs as well other devices: - drop profile field from priv data - drop iosize field from priv data - drop enum_apu_led_platform_types - drop superseeded apu2/3 led support - add pr_fmt prefix for better log output - fix error message on probing failure Other misc fixes and improvements to existing LED class drivers: - leds-ns2, leds-max77650: - add of_node_put() before return - leds-pwm, leds-is31fl32xx: - use struct_size() helper - leds-lm3697, leds-lm36274, leds-lm3532: - switch to use fwnode_property_count_uXX() - leds-lm3532: - fix brightness control for i2c mode - change the define for the fs current register - fixes for the driver for stability - add full scale current configuration - dt: Add property for full scale current. - avoid potentially unpaired regulator calls - move static keyword to the front of declarations - fix optional led-max-microamp prop error handling - leds-max77650: - add of_node_put() before return - add MODULE_ALIAS() - Switch to fwnode property API - leds-as3645a: - fix misuse of strlcpy - leds-netxbig: - add of_node_put() in netxbig_leds_get_of_pdata() - remove legacy board-file support - leds-is31fl319x: - simplify getting the adapter of a client - leds-ti-lmu-common: - fix coccinelle issue - move static keyword to the front of declaration - leds-syscon: - use resource managed variant of device register - leds-ktd2692: - fix a typo in the name of a constant - leds-lp5562: - allow firmware files up to the maximum length - leds-an30259a: - fix typo - leds-pca953x: - include the right header" * tag 'leds-for-5.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/j.anaszewski/linux-leds: (72 commits) leds: lm3532: Fix optional led-max-microamp prop error handling led: triggers: Fix dereferencing of null pointer leds: ti-lmu-common: Move static keyword to the front of declaration leds: lm3532: Move static keyword to the front of declarations leds: trigger: gpio: GPIO 0 is valid leds: pwm: Use struct_size() helper leds: is31fl32xx: Use struct_size() helper leds: ti-lmu-common: Fix coccinelle issue in TI LMU leds: lm3532: Avoid potentially unpaired regulator calls leds: syscon: Use resource managed variant of device register leds: Replace {devm_}led_classdev_register() macros with inlines leds: Allow to call led_classdev_unregister() unconditionally leds: lm3532: Add full scale current configuration dt: lm3532: Add property for full scale current. leds: lm3532: Fixes for the driver for stability leds: lm3532: Change the define for the fs current register leds: lm3532: Fix brightness control for i2c mode leds: Switch to use fwnode instead of be stuck with OF one leds: max77650: Switch to fwnode property API led: triggers: Fix a memory leak bug ...

regulator: core: make regulator_register() EPROBE_DEFER aware

2019-09-17T15:59:38Z

Sometimes it can happen that the regulator_of_get_init_data() can't retrieve the config due to a not probed device the regulator depends on. Fix that by checking the return value of of_parse_cb() and return EPROBE_DEFER in such cases.

regulator: of: fix suspend-min/max-voltage parsing

2019-09-17T15:59:18Z

Currently the regulator-suspend-min/max-microvolt must be within the root regulator node but the dt-bindings specifies it as subnode properties for the regulator-state-[mem/disk/standby] node. The only DT using this bindings currently is the at91-sama5d2_xplained.dts and this DT uses it correctly. I don't know if it isn't tested but it can't work without this fix.
