No code within the kernel uses this API, it is retained only for drivers outside the kernel which might still need it. config STM_DMA bool "STMicroelectronics DMA API" select SH_DMA_API select LIBELF default y ---help--- Selecting this option will provide support for STMicroelectronics' custom DMA API. This API provides support for data transfers of various dimensions and complex linked list operations. In addition to these free-running operations it also allows management of the paced-transfer peripherals on recent STM parts. If you have a device from STMicroelectronics, then say Y here. Otherwise say N. config STM_DMA_DEBUG bool "STMicroelectronics DMA Debug" depends on STM_DMA default n config STM_COPROCESSOR_SUPPORT bool "STMicroelectronics coprocessor support" default y depends on (CPU_SUBTYPE_STX7100 || CPU_SUBTYPE_STX7105 \ || CPU_SUBTYPE_STX7111 || CPU_SUBTYPE_STX7141 \ || CPU_SUBTYPE_STX7200 || CPU_SUBTYPE_STX7108 \ || CPU_SUBTYPE_STX5206 \ || CPU_SUBTYPE_FLI7510) ---help--- Many of the ST system-on-chip devices have multiple CPUs, where a master CPU running Linux has control over a number of slave CPUs, which are usually used to run dedicated algorithms. Enabling this option will add support to the Linux kernel to control these slave CPUs, reserve memory for them, and thus allow code to be downloaded onto them and executed. Adding in the command line the following string: coprocessor_mem=[offset]:size0[,size1][,size2]... where: offset defines where the co-processors region starts. It's an offset from ST40 RAM start. size{n} defines the region size for the n.th slave core (max 16M).

It allows the RNG to feed /dev/random with entropy thereby ensuring real random numbers from this device. Without this option, /dev/random has little entropy and is not useful. In fact, it may block for a long time while waiting for entropy. This option should always be enabled for relevant SoCs. This option can be used in conjunction with the /dev/hw_random driver found in the char drivers menu. config STM_MALI depends on CPU_SUBTYPE_STX7108 tristate "STM Mali GPU support" default n help Enable this option to support Mali GPU Driver. config STM_MALI_DEBUG depends on STM_MALI bool "Enable debug tracing" default y ---help--- Enable this option to enable debug trace messages on the console config STM_LPC bool "Low power control" depends on PM default n ---help--- This option adds support for the hardware Low Power Control tu support the wakeup_on_timeout in the suspend operation. config STM_LPC_DEBUG depends on STM_LPC bool "LPC debug" default n ---help--- Enable this option to print out information about the LPC config PMS bool "Power Management Scheme" default n depends on PM select PM_RUNTIME help This option enables the STMicroelectronics Power Management Scheme (PMS). This is a kernel framework based around power profiles (pms_state), where the designer can specify devices power states and the clock frequency rates. Moving the system between pms_states the user application can tune the power consumption according with what the system is doing. config PMS_CHECK_GROUP bool "PMS always checks the state group" depends on PMS default n help Enable this option if the state group has to be controlled. When a group of pms_states are enabled in the same time, this option forces the PMS to check that there is no conflict inside the group itself. In case of conflict the group is rejected. config PMS_DEBUG bool "PMS debug" default n depends on PMS help Enable this option to print out information about the PMS config STM_LPM bool "STM Low Power Monitor" depends on STM_DRIVERS default n ---help--- This option adds support for the hardware low power monitor. config STM_LPM_RD_MONITOR bool "STM Low Power Monitor power key press on GPIO" depends on STM_LPM default n ---help--- This enable intercept of GPIO activity by STLPM_POWER config STM_LPM_DEBUG bool "STM Low Power Monitor debug" depends on STM_LPM default n ---help--- Enable this option to print out information about the LPM endmenu
