The S2MPS15 PMIC is similar in functionality to S2MPS11/14 PMIC. It contains 27 LDO and 10 Buck regulators, RTC, three 32.768 KHz clock outputs and allows programming these blocks via a I2C interface. This patch series adds initial support for LDO/Buck regulators of S2MPS15 PMIC. Changes since v4: * Dorpped Krzysztof reviewed-by and Lee Acked-by tags from patch 1/4, because of the new changes to DT bindings. Seeking a fresh review/ack tags. * Removed samsung,s2mps15-clk compatible as we can reuse exsisting compatible of s2mps13. * Added acked-by on patch 2/4 * Modified rtc driver as s2mps15 differs from s2mps14/13 etc, addressed Krzysztof concerns on rtc patch. There are some other improvement suggestion from Krzystof for the rtc, I feel that can be done as a sperate patch later. Changes since v3: * Changes regulator driver name from s2mps15-pmic -> s2mps15-regulator as disscussed here [2] * Re-use the exsisting compatible/names for s2mps15 clock block. Changes since v2: * Addressed Lee Jones review comments. Changes since v1: * Added suggestion from Krzysztof [1]. * Added s2mps15's 32.768 clocks support. * Added s2mps15's rtc support. V1 of these patches (with a lesser features) were posted a year back, since then there is not much progress on this, this is my attempt to move things forward.
