2012-07-12regulator: tps65910: Remvoe ↵Axel Lin1-111/+73
tps65910_reg_[read|modify_bits|read_locked|write_locked] functions The tps65910 mfd driver has been converted to regmap APIs. This patch adds tps65910_reg_update_bits() in include/linux/mfd/tps65910.h. Thus we can use tps65910_reg_read/tps65910_reg_write/tps65910_reg_update_bits directly and remove tps65910_reg_[read|modify_bits|read_locked|write_locked] functions. With this change, we can also remove the mutex in struct tps65910_reg.

2012-07-10regulator: tps65910: correct init value of n_voltagesLaxman Dewangan1-11/+11
Recent change in the core driver to get the maximum voltage is based on the (n_voltages -1) steps of voltage. For the tps65910, the (n_voltages -1)th step voltage is calculated based on the callback function list_voltage. This function direct maps the datasheet and adjust the first few steps for initial voltage as per datasheet, and hence initialize the n_voltages based on datasheet.

2012-07-03regulator: core: Add core support for GPIO controlled enable linesMark Brown1-1/+34
It is very common for regulators to support having their enable signal controlled by a GPIO. Since there are a bunch of fiddly things to get right like handling the operations when the enable signal is tied to a rail and it's just replicated code add support for this to the core. Drivers should set ena_gpio in their config if they have a GPIO control, using ena_gpio_flags to specify any flags (including GPIOF_OUT_INIT_ for the initial state) and ena_gpio_invert if the GPIO is active low. The core will then override any enable and disable operations the driver has and instead control the specified GPIO. This will in the future also allow us to further extend the core by identifying when several enable signals have been tied together and handling this properly.

2012-07-03regulator: tps65217: Fix voltage boundary checking in tps65217_pmic_map_voltageAxel Lin1-3/+3
It is ok to request voltage with min_uV < tps->info[rid]->min_uV and max_uV > tps->info[rid]->max_uV. The equation we used in uv_to_vsel() does not allow min_uV < tps->info[rid]->min_uV, otherwise it returns negative selector. So we need to set min_uV = tps->info[rid]->min_uV if min_uV < tps->info[rid]->min_uV.

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.

2012-06-30acpi_pad: fix power_saving thread deadlockStuart Hayes1-3/+4
The acpi_pad driver can get stuck in destroy_power_saving_task() waiting for kthread_stop() to stop a power_saving thread. The problem is that the isolated_cpus_lock mutex is owned when destroy_power_saving_task() calls kthread_stop(), which waits for a power_saving thread to end, and the power_saving thread tries to acquire the isolated_cpus_lock when it calls round_robin_cpu(). This patch fixes the issue by making round_robin_cpu() use its own mutex. https://bugzilla.kernel.org/show_bug.cgi?id=42981 Cc: stable@vger.kernel.org Signed-off-by: Stuart Hayes <Stuart_Hayes@Dell.com> Signed-off-by: Len Brown <len.brown@intel.com>

In commit 7a87982420e5e126bfefeb42232d1fd92052794e we added a wrapper for the WDIOC_GETSTATUS ioctl call. The code results however in a different behaviour: it returns an error if the driver doesn't support the status operation. This is not according to the API that says that when we don't support the status operation, that we just should return a 0 value. Only when the device isn't there anymore, we should return an error.
