| config PWM_NPCX |
| default y |
| depends on PWM |
| help |
| Enable support for NPCX PWM driver. |
| |
| config ADC_NPCX |
| default y |
| depends on ADC |
| help |
| Enable support for NPCX ADC driver. In NPCX7 series, it includes a |
| 10-bit resolution Analog-to-Digital Converter (ADC). Up to 10 voltage |
| inputs can be measured and a internal voltage reference (VREF), 2.816V |
| (typical) is used for measurement. |
| |
| config WDT_NPCX |
| default y |
| depends on WATCHDOG |
| help |
| Enable support for NPCX Watchdog driver. Besides watchdog |
| functionality, it also provides the protection mechanism over software |
| execution. After setting the configuration registers, the software can |
| lock it to provide a higher level of protection against subsequent |
| erroneous software action. Once a section of the TWD is locked, only |
| reset or the unlock sequence releases it. |
| |
| config ESPI_NPCX |
| default y |
| depends on ESPI |
| help |
| Enable support for NPCX ESPI driver. The Intel Enhanced Serial |
| Peripheral Interface (eSPI) provides a path for migrating host |
| sub-devices via LPC to a lower pin count, higher bandwidth bus. |
| So far, this driver supports all of functionalities beside flash |
| channel support. It will be supported in the future. Please refer |
| https://www.intel.com/content/www/us/en/support/articles/000020952/ |
| software/chipset-software.html for more detail. |
| |
| config I2C_NPCX |
| default y |
| depends on I2C |
| help |
| Enable support for NPCX I2C driver. The NPCX SMB/I2C modules provides |
| full support for a two-wire SMBus/I2C synchronous serial interface. |
| Each interface is a two-wire serial interface that is compatible with |
| both Intel SMBus and Philips I2C physical layer. There are 8 SMBus |
| modules and 10 buses in NPCX7 series. |
| |
| config TACH_NPCX |
| default y |
| depends on SENSOR |
| help |
| Enable support for NPCX tachometer sensor driver. The NPCX7 series |
| contains two tachometer (TACH) modules that contains two counters |
| (counter A and B). They are used to capture/compare a counter value |
| when an event is generated on comparison of signals match. |
