regulator: palmas: fix typo in enable_reg calculation

2014-06-24T10:58:36Z

When setting up .enable_reg for an SMPS regulator, presumably we should call PALMAS_BASE_TO_REG(PALMAS_SMPS_BASE, ...) rather than using LDO_BASE. This change makes the LCD panel and HDMI work again on the NVIDIA Dalmore board anyway.

regulator: bcm590xx: fix vbus name

2014-06-22T11:00:14Z

The vbus regulator was not getting its name set. This results in the sysfs entry being empty. The lack of a bcm590xx_regs[] table entry also upsets Coverity runs. Add the table entry so the name gets set properly. Signed-off-by: Graham Williams Acked-by: Matt Porter Signed-off-by: Mark Brown

regulator: palmas: Fix SMPS enable/disable/is_enabled

2014-06-21T10:22:09Z

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.

Pull module updates from Rusty Russell: "Most of this is cleaning up various driver sysfs permissions so we can re-add the perm check (we unified the module param and sysfs checks, but the module ones were stronger so we weakened them temporarily). Param parsing gets documented, and also "--" now forces args to be handed to init (and ignored by the kernel). Module NX/RO protections get tightened: we now set them before calling parse_args()" * tag 'modules-next-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux: module: set nx before marking module MODULE_STATE_COMING. samples/kobject/: avoid world-writable sysfs files. drivers/hid/hid-picolcd_fb: avoid world-writable sysfs files. drivers/staging/speakup/: avoid world-writable sysfs files. drivers/regulator/virtual: avoid world-writable sysfs files. drivers/scsi/pm8001/pm8001_ctl.c: avoid world-writable sysfs files. drivers/hid/hid-lg4ff.c: avoid world-writable sysfs files. drivers/video/fbdev/sm501fb.c: avoid world-writable sysfs files. drivers/mtd/devices/docg3.c: avoid world-writable sysfs files. speakup: fix incorrect perms on speakup_acntsa.c cpumask.h: silence warning with -Wsign-compare Documentation: Update kernel-parameters.tx param: hand arguments after -- straight to init modpost: Fix resource leak in read_dump()

regulator: palmas: Fix SMPS list for 0V

2014-06-05T11:40:51Z

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) 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.
