u-boot.git/include/power, branch v2022.07 Unnamed repository; edit this file 'description' to name the repository. rockchip: Add option to prevent booting on power plug-in 2022-06-29T03:42:10+00:00 Chris Morgan macromorgan@hotmail.com 2022-05-27T18:18:20+00:00 30975fb73d51f65d95e9508e4af9c85badd5388c For Rockchip boards with the all rk8xx series PMICs (excluding the rk808), it is sometimes desirable to not boot whenever the device is plugged in. An example would be for the Odroid Go Advance. This provides a configurable option to check the PMIC says it was powered because of a plug-in event. If the value is 1 and this option is selected, the device shuts down shortly after printing a message to console stating the reason why it's shutting down. Powering up the board with the power button is not affected.

There is AB8500, AB8505, AB9540 and AB8540 although in practice only AB8500 and AB8505 are relevant since the platforms with AB9540 and AB8540 were cancelled and never used in production. In general, the AB8500 PMIC uses I2C as control interface, where the different register banks are represented as separate I2C devices. However, in practice AB8500 is always connected to a special I2C bus on the DB8500 SoC that is controlled by the power/reset/clock management unit (PRCMU) firmware. Add a simple driver that allows reading/writing registers of the AB8500 PMIC. The driver directly accesses registers from the PRCMU parent device (represented by syscon in U-Boot). Abstracting it further (e.g. with the i2c uclass) would not provide any advantage because the PRCMU I2C bus is always just connected to AB8500 and vice-versa. The ab8500.h header is mostly taken as-is from Linux (with some minor adjustments) to allow using similar code in both Linux and U-Boot.
