# # External soc control infrastructure and drivers # menuconfig ESOC bool "External SOCs Control" help External SOCs can be powered on and monitored by user space or kernel drivers. Additionally they can be controlled to respond to control commands. This framework provides an interface to track events related to the external slave socs. if ESOC config ESOC_DEV bool "ESOC userspace interface" help Say yes here to enable a userspace representation of the control link. Userspace can register a request engine or a command engine for the external soc. It can receive event notifications from the control link. config ESOC_CLIENT bool "ESOC client interface" depends on OF help Say yes here to enable client interface for external socs. Clients can specify the external soc that they are interested in by using device tree phandles. Based on this, clients can register for notifications from a specific soc. config ESOC_DEBUG bool "ESOC debug support" help Say yes here to enable debugging support in the ESOC framework and individual esoc drivers. config ESOC_MDM_4x bool "Add support for external mdm9x25/mdm9x35" help In some qualcomm boards, an external modem such as mdm9x25 or mdm9x35 is connected to a primary msm. The primary soc can control/monitor the modem via gpios. The data communication with such modems can occur over PCIE or HSIC. config ESOC_MDM_DRV tristate "Command engine for 4x series external modems" help Provides a command engine to control the behavior of an external modem such as mdm9x25/mdm9x35/QSC. Allows the primary soc to put the external modem in a specific mode. Also listens for events on the external modem. endif
