[PATCH v4 00/16] rockchip: add support for SARADCv2 and RK806 PMIC and regulators
The RK3588 has a new IP for SARADC compared to older SoCs of the same vendor but most of the boilerplate is shared, so rockchip-saradc.c driver is adapted instead of creating a new one.
Because the SARADC requires a vref-supply which is commonly coming from a regulator of the RK806 PMIC, support for the RK806 PMIC and regulators are also added in this patch series. Finally, RK806 PMIC is the first one to actually support SPI as communication layer between the SoC and the PMIC (but supports I2C as well according to the datasheet). This adds support for RK806 over SPI though there should be no reason for RK806 over I2C to not work.
Note that the DT now uses a different prefix for the buck and ldo node names and the RK806 is the first one to use nldo and pldo and while they both are LDOs, they have overlapping indices which makes it impossible to simply reuse the rk8xx_ldo driver and need to define new ones (though some callbacks can be reused, as is done in this patch series).
The SARADC was tested by toggling the BIOS button connected over channel 0 on RK3588 Jaguar and using the adc or button commands to watch over the value. The PMIC was tested with the pmic command for reading the CHIP_VERS registers and writing to the WDT_REG (0x73). The regulators were tested by using a modified DT for RK3588 Jaguar and playing with the regulator command to enable/disable some buck/nldo/pldo and modify their output voltage.
This has a light dependency on https://lore.kernel.org/u-boot/20240221-jaguar-v3-0-1f256a82201b@theobroma-s... because of: - remove of asm/io.h include in favor of asm/arch-rockchip/hardware.h (both should be included if applied before the dependency) - Jaguar defconfig modified in this patch series is added in the aforementioned patch series,
Signed-off-by: Quentin Schulz quentin.schulz@theobroma-systems.com --- Changes in v4: - use uint8_t instead of char to fix clang's -Wsingle-bit-bitfield-constant-conversion for the members of rk806_cmd data structure, they all are storing unsigned numbers anyway, - Link to v3: https://lore.kernel.org/r/20240304-rk3588-saradc-v3-0-7424e2ed5d3b@theobroma...

The read-only mode is currently supported but only for 16b-aligned buffers. For unaligned buffers, the last byte will be read in RW mode right now, which isn't what is desired. Instead, let's put the controller back into RO mode for that last byte and skip any write in the xfer loop.
This is required for 3-wire SPI mode where PICO/POCI lanes are shorted on HW level. This incidentally the recommended design for RK806 PMIC for RK3588 products.

On RK809 in PMIC_POWER_ENX registers, in order to set or clear a bit N, the bit at offset N + 4 needs to be set otherwise nothing is done.
This fixes the inability to modify the SWITCH state on RK809.

By passing a rk8xx_reg_info directly to the internal get_value, it'd be possible to call this same function with a logic for getting the rk8xx_reg_info different from the current get_ldo_reg, e.g. for NLDO and PLDO support for RK806.
No logic change is expected.

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.

This adds support for the SARADCv2 found on RK3588.
There is no stop callback as it is currently configured in single conversion mode, where the ADC is powered down after a single conversion has been made.
Due to what seems to be a silicon bug, a controller reset needs to be issued before starting a channel conversion otherwise Rockchip says that channel 1 will error whatever that means. This is aligned with upstream and downstream Linux kernel as well as downstream U-Boot.

The SARADC is used on Jaguar for multiple things: - channel 0 is used (at runtime) as a BIOS button, - channel 2 is exposed on the Mezzanine connector for customer specific logic, - channel 5 and 6 are used for identification,
Since the SARADC requires a vref-supply provided by the RK806 PMIC, its support and the support for its regulators are also enabled.
The button, adc, pmic and regulator commands are also enabled for CLI use in U-Boot for debugging and scripting purposes.
The RK806 PMIC on Jaguar being routed on the SPI bus, let's enable Rockchip SPI controller driver.
Finally, the SARADC channel 1 on Jaguar is hardwired so will never change in the lifetime of a unit, for that reason, disable the Rockchip Download Mode check by setting ROCKCHIP_BOOT_MODE_REG symbol to 0.

The ADC controller drivers are obviously all depending on ADC symbol being selected.
While they don't seem to fail to build without, they won't be useful without that symbol selected, so let's make sure the options aren't shown in menuconfig when ADC isn't selected.

ADC support is implied by the Rockchip arch Kconfig but that means it should be possible to disable ADC support and still be able to build.
However the weak implementation of rockchip_dnl_key_pressed() currently blindly use functions from the ADC subsystem which do not exist when ADC is not enabled, failing the build.
Therefore, let's encapsulate this logic with a check on the ADC symbol being selected.
