2024-03-14power: pmic: rk8xx: fix duplicate promptQuentin Schulz1-1/+1
SPL_PMIC_RK8XX and PMIC_RK8XX both share the same prompt making it difficult to know at first glance in menuconfig what's for what, let's fix this by adding "in SPL" at the end of the prompt for the SPL symbol.

2024-03-14power: rk8xx: add support for RK806Quentin Schulz1-0/+91
This adds support for RK806, only the SPI variant has been tested. The communication "protocol" over SPI is the following: - write three bytes: - 1 byte: [0:3] length of the payload, [6] Enable CRC, [7] Write - 1 byte: LSB register address - 1 byte: MSB register address - write/read length of payload The CRC is always disabled for now. The RK806 technically supports I2C as well, and this should be able to support it without any change, but it wasn't tested. The DT node name prefix for the buck converters has changed in the Device Tree and is now dcdc-reg. The logic for buck converters is however manageable within the current logic inside the rk8xx regulator driver. The same cannot be said for the NLDO and PLDO. Because pmic_bind_children() parses the DT nodes and extracts the LDO index from the DT node name, NLDO and PLDO will have overlapping indices. Therefore, we need a separate logic from the already-existing ldo callbacks. Let's reuse as much as possible though.

The RZ/G2L SMARC module is powered via a Renesas RAA215300 PMIC which provides several voltage converters, a real time clock (RTC) and reset control. A basic driver is implemented for this device so that we can read, write and dump the PMIC registers. The raa215300_bind() function is added as a stub, binding of the sysreset driver will be added in a later patch. Additional features of this PMIC (such as reset control) may be supported by future patches.

Linux DTs stuff a value indicating if the USID is a USID or a GSID in the reg property, the Linux SPMI driver then reads the two address cells separately. U-boot's dev_read_addr() doesn't know how to handle this, so use ofnode_read_u32_index() to get just the USID. The Qcom pmic driver doesn't have support for GSID handling, so just ignore the second value for now.

2023-10-07power: pmic: rk8xx: Fix power-on source check in SPLJonas Karlman1-7/+13
The commit 30975fb73d51 ("rockchip: Add option to prevent booting on power plug-in") introduce an option to prevent booting a device when the device was powered on due to power plug-in instead of pressing a power button. This feature works by checking the power-on source during PMIC probe and powers off the device if power-on source was power plug-in. This check currently runs very late at PMIC probe in U-Boot proper. Fix so that the power-on source check can work at probe time in SPL. Also enable probe after bind and remove the PMIC banner in SPL. With this we can use ROCKCHIP_RK8XX_DISABLE_BOOT_ON_POWERON and SPL_PMIC_RK8XX to power off the device very quickly after TPL instead of after TF-A and U-Boot proper has been loaded and run.

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.

LDO5 has two separate control registers. LDO5CTRL_L is used if the input signal SD_VSEL is low and LDO5CTRL_H if it is high. The current driver implementation only uses LDO5CTRL_H. To make this work on boards that have SD_VSEL connected to a GPIO, we add support for specifying an optional GPIO and setting it to high at probe time. In the future we might also want to add support for boards that have SD_VSEL set to a fixed low level. In this case we need to change the driver to be able to use the LDO5CTRL_L register.
