Currently s2mps11->iodev, s2mps11->dev and config.dev point to NULL. This patch fixes the settings for config.dev. Current code does not need the *dev and *iodev of struct s2mps11_info, so remove them.

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.

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.

It is ok to request current limit with min_uA < chip->min_uA and max_uA > chip->max_uA. We need to set min_uA = chip->min_uA if (min_uA < chip->min_uA), this ensures the equation to calcuate selator does not return negative number. Also set max_uA = chip->max_uA if (max_uA > chip->max_uA), as suggested by Sonic.

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.

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.

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.
