Doug Anderson 8af252272a regulator: rk808: Add function for ramp delay for buck1/buck2
On rk808 buck1 and buck2 have programmable ramp delays.  Let's add a
function to allow a client of rk808 to set them.

Axel Lin 1ed3f8ce83 regulator: rk808: Fix missing of_node_put
1. Pass &pdev->dev rather than &client->dev to of_regulator_match, the *dev
   argument is used for devres to ensure devm_of_regulator_put_matches() will
   be called when unload the module.

2. of_get_child_by_name() returns a node pointer with refcount incremented.
   Thus add missing of_node_put(reg_np).

Axel Lin 5a82067f01 regulator: rk808: Fix n_voltages for DCDC4
The min_sel is 0, max_sel is 15, so n_voltages should be 16.

Axel Lin c61519fd9a regulator: rk808: Fix memory leak
The memory allocated in rk808_regulator_probe() needs to be freed when the
module is unloaded. Thus pass &pdev->dev rather than &client->dev to
devm_kzalloc.

so rk808->dev should be replaced by &client->dev here.

Doug Anderson 462004f121 regulator: rk808: Fix uninitialized value
The RK808 regulator driver was putting its config on the stack but not
initting it.  That means that you got a semi-random config.  Fix this.
