* zephyr: add batteries to device treeMichał Barnaś2021-09-031-0/+2
| | | | | | | | | | | | | | | | | | | | | | This commit adds possibility to define board's batteries in device tree. Default battery is defined by adding "default_battery" as node's label. It also adds common batteries definitions that can be used using compatible string. If no 'batteries' node is defined in device tree, custom board's logic must be used and old "named-batteries" should be defined.

The decision about which sensor is made in runtime thus all drivers have to be built-in.

* Add chip-specific shim along with i2c moduleYuval Peress2020-11-081-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change accomplishes 2 things: 1. It refactors the zephyr/shim directory to structure around chip specific compilation. In this example, we're focusing on npcx7m6fb which is used in volteer but others can be added easily. 2. It shims the common/i2c_master.c by providing an alternate implementation of i2c_xfer_unlocked that calls down to the Zephyr API i2c_write_read instead of the chip specific i2c_xfer_no_retry or chip_i2c_xfer_with_notify. The shim layer is made possible by the addition of zephyr/shim/include/i2c/i2c.h which adds a functions that needs to be implemented per chip (npcx7 family in this case) and allows us to map the current port int which is defined in chip/${CHIP}/registers.h (chip/npcx/registers-npcx7.h in our case). This function (i2c_get_device_for_port) maps the platform/ec port int to a const struct device * which is needed in the Zephyr I2C APIs.

The event timer does not make sense for Zephyr code, but we need it defined to prevent link errors (timerinfo uses it). Perhaps the solution to this is to add a new config option (e.g., CONFIG_EVENT_TIMER) which can be used to selectively enable/disable the event timer in the CrOS EC. But punting this work for now and just adding a fake definition.
