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-systems.com/T/#t
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,
