| * power: domain: add i.MX8 scu power domain driverPeng Fan2019-11-052-1/+88
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The power domain tree is not accepted by Linux Kernel upstream. only a single pd node is used currently, as following: pd: imx8qx-pd { compatible = "fsl,imx8qm-scu-pd", "fsl,scu-pd"; #power-domain-cells = <1>; }; So to migrate to use upstream linux dts, we also need a driver to support this. This patch is to support the new method, compared with legacy power domain tree, it will be simpiler, because each device will has resource id as power domain index, it will be directly passed to scfw, and no need to let power domain build that tree. If multiple power domain is needed, it is the dts node should has correctly power domains entry added and sequence correct. Signed-off-by: Peng Fan <peng.fan@nxp.com>

| | | | | | | | | | | | | | | | | | | | | | | | The current i.MX8 power domain driver is based on i.MX vendor power domain tree which will retire later. The Linux upstream use a single pd node for power domain driver, and U-Boot will adopt that. When U-Boot i.MX8 dts synced with Linux Kernel upstream and related driver ready, the legacy driver will be removed. Signed-off-by: Peng Fan <peng.fan@nxp.com>

* | regulator: bd718x7: support ROHM BD71837 and BD71847 PMICsMatti Vaittinen2019-07-194-5/+513
|/ | | | | | | | | | | | | | | | | | | | | | | | | BD71837 and BD71847 is PMIC intended for powering single-core, dual-core, and quad-core SoC’s such as NXP-i.MX 8M. BD71847 is used for example on NXP imx8mm EVK. Add regulator driver for ROHM BD71837 and BD71847 PMICs. BD71837 contains 8 bucks and 7 LDOS. BD71847 is reduced version containing 6 bucks and 6 LDOs. Voltages for DVS bucks (1-4 on BD71837, 1 and 2 on BD71847) can be adjusted when regulators are enabled. For other bucks and LDOs we may have over- or undershooting if voltage is adjusted when regulator is enabled. Thus this is prevented by default. BD718x7 has a quirk which may leave power output disabled after reset if enable/disable state was controlled by SW. Thus the SW control is only allowed for BD71837 bucks 3 and 4 by default. The impact of this limitation must be evaluated board-by board and restrictions may need to be modified. (Linux driver get's these limitations from DT and we may want to implement same on u-Boot driver).
