power: domain: add i.MX8 scu power domain driver

2019-11-05T09:27:18Z

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

power: domain: make imx8-power-domain.c legacy

2019-11-05T09:27:18Z

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

power: domain: add Amlogic Everything-Else power domain driver

2019-10-18T12:33:21Z

Based on the 54ecb8f7028c ("Linux 5.4-rc1") Everything-Else power domain driver for Amlogic SoCs. This driver handles the VPU Power domain and other domains from the Everything-Else part of the SM1 and G12A SoCs. Signed-off-by: Neil Armstrong

imx: add support for i.MX8MQ power domain controller

2019-10-08T14:36:36Z

Add support for the power domain controller that's used on the i.MX8MQ. This will be needed to be able to power on the PCIe controller. Bindings taken from Linux, driver implementation taken from the i.MX8 power domain controller and adjusted for the i.MX8M SoC. Signed-off-by: Patrick Wildt

power: domain: ti-sci-power-domain: Add device ID info to get/set_device failure

2019-08-12T17:33:38Z

Failure log for ti_sci_power_domain_on/off is as below: "ti_sci_power_domain_on: get/set_device failed (-19)" The above information is useless for debug without information on what specific device access failed. So add that information as well. Signed-off-by: Nishanth Menon Signed-off-by: Lokesh Vutla

power: domain: ti_sci_power_domains: Add support for exclusive and shared access

2019-07-27T01:49:23Z

TISCI protocol supports for enabling the device either with exclusive permissions for the requesting host or with sharing across the hosts. There are certain devices which are exclusive to Linux context and there are certain devices that are shared across different host contexts. So add support for getting this information from DT by increasing the power-domain cells to 2. For keeping the DT backward compatibility intact, defaulting the device permissions to set the exclusive flag set. In this case the power-domain-cells is 1. Signed-off-by: Lokesh Vutla
