| * regulator: vctrl: Fix out of bounds array access for vctrl->vtableAxel Lin2017-04-141-4/+4
| | | | | | | | | | | | | | | | | | | | | | Current code only allocates rdesc->n_voltages entries for vctrl->vtable. Thus use rdesc->n_voltages instead of n_voltages in the for loop. While at it, also switch to use devm_kcalloc instead of devm_kmalloc_array + __GFP_ZERO flag and fix the argument order.

| * regulator: Add driver for voltage controlled regulatorsMatthias Kaehlcke2017-04-103-0/+554
| | | | | | | | | | | | | | | | | | | | | | The output voltage of a voltage controlled regulator can be controlled through the voltage of another regulator. The current version of this driver assumes that the output voltage is a linear function of the control voltage.

| | | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some regulators (some PWM regulators) have the voltage transition non-linear i.e. exponentially. On such cases, the settling time for voltage transition can not be presented in the voltage-ramp-delay.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we are propagating voltage changes to parent regulators don't bother if the parent does not have permission to change voltages. This simplifies error checking in the function for cases where the regulator lacks some of the voltage operations.

The goal is to support simple switch regulators, however as a side effect normal continuous regulators can leak details of their supplies and provide consumers with inconsistent information. Limit the propagation of the voltage count and list to switch regulators.

The description found for the return value is: @ret: 0 on success, -ENODEV if lookup fails permanently, -EPROBE_DEFER if lookup could succeed in the future.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The supply_name member of struct regulator can be const as we don't change it in the regulator core. Furthermore, when we copy the supply name we can use kstrdup_const() here to avoid a copy if the name is in the ro data section.

| | |/ / | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When creating the link to the device sysfs entry, the regulator core calls scnprintf() and then checks if the returned value is greater or equal than the buffer size. The former can never happen as scnprintf() returns the number of bytes that were actually written to the buffer, not the bytes that *would* have been written. Use the right function in this case: snprintf(). Signed-off-by: Bartosz Golaszewski <bgolaszewski@baylibre.com> Signed-off-by: Mark Brown <broonie@kernel.org>
