if PLATFORM_EC_HOST_INTERFACE_ESPI
config PLATFORM_EC_HOST_INTERFACE_ESPI_VW_SLP_S3
bool "SLP_S3 is an eSPI virtual wire instead of a GPIO"
help
For power sequencing, use an eSPI virtual wire instead of
defining GPIO_PCH_SLP_S3 in the GPIO device tree.
config PLATFORM_EC_HOST_INTERFACE_ESPI_VW_SLP_S4
bool "SLP_S4 is an eSPI virtual wire instead of a GPIO"
help
For power sequencing, use an eSPI virtual wire instead of
defining GPIO_PCH_SLP_S4 in the GPIO device tree.
config PLATFORM_EC_HOST_INTERFACE_ESPI_VW_SLP_S5
bool "SLP_S5 is an eSPI virtual wire instead of an alias for SLP_S4"
help
For power sequencing, use an eSPI virtual wire to read the SLP_S5 line,
as opposed to merging it into the same net as SLP_S4.
config PLATFORM_EC_HOST_INTERFACE_ESPI_RESET_SLP_SX_VW_ON_ESPI_RST
bool "Reset SLP VW signals on eSPI reset"
help
Enable this config to reset SLP* VW when eSPI_RST is asserted
for the Global Reset event case. Don't enable this config if
the platform implements the Deep-Sx entry as EC needs to
maintain these pins' states per request. Note that this is
currently unimplemented for Zephyr. Please see b/183148073.
config PLATFORM_EC_HOST_INTERFACE_ESPI_DEFAULT_VW_WIDTH_US
int "Virtual wire pulse width (microseconds)"
default 65
help
The minimum pulse width of a eSPI/LPC virtual wire signals to the
host. May vary by host chipset.
