2019-02-02regulator: rk808: Fix BUCK1/2 voltages on rk805Otavio Salvador
RK805 has the following voltage range for the BUCK1 and BUCK2 regulators: From 0.7125V to 1.45V in 12.5mV steps, 1.8V, 2V, 2.2V and 2.3V , which corresponds to the following values as per the RK805 datasheet: 000 000: 0.7125V 000 001: 0.725V …… 111 011: 1.45V 111 100: 1.8V 111 101: 2.0V 111 110: 2.2V 111 111: 2.3V This means that the voltage range is not linear and so RK805 can not reuse the same regulator_ops structure from RK808. Fix it by creating a list with the correct supported voltage values for RK805 BUCK1 and BUCK2 regulators. Tested on a rv1108-elgin-r1 board that now correctly reports a BUCK2 voltage of 2.2V instead of the unsupported value of 1.4875V.

Since c32569e358ad ("regulator: Use of_node_name_eq for node name comparisons") Vivien reported the mc13892-regulator complaining about not being able to find regulators. This is because prior to that commit we used of_node_cmp() to compare the regulator array passed from mc13892_regulators down to mc13xxx_parse_regulators_dt() and they are all defined in uppercase letters by the MC13892_*_DEFINE* macros, whereas they are defined as lowercase in the DTS.

2019-01-22regulator: qcom-smd: Batch up requests for disabled regulatorsBjorn Andersson
In some scenarios the early stages of the boot chain has configured regulators to be in a required state, but the later stages has skipped to inform the RPM about it's requirements. But as the SMD RPM regulators are being initialized voltage change requests will be issued to align the voltage with the valid ranges. The RPM aggregates all parameters for the specific regulator, the voltage will be adjusted and the "enabled" state will be "off" - and the regulator is turned off. This patch addresses this problem by caching the requested enable state, voltage and load and send the parameters in a batch, depending on the enable state - effectively delaying the voltage request for disabled regulators.
