mfd: rk8xx: Add rk806 support Add support for SPI connected rk806, which is used by the RK3588 evaluation boards. The PMIC is advertised to support I2C and SPI, but the evaluation boards all use SPI. Thus only SPI support is added here.

mfd: rk808: Convert RK805 to shutdown/suspend hooks RK805 has the same kind of dual-role sleep/shutdown pin as RK809/RK817, so it makes little sense for the driver to have to have two completely different mechanisms to handle essentially the same thing.

mfd: rk808: Fix RK818 ID template The Rockchip PMIC driver can automatically detect connected component versions by reading the ID_MSB and ID_LSB registers. The probe function will always fail with RK818 PMICs because the ID_MSK is 0xFFF0 and the RK818 template ID is 0x8181. This patch changes this value to 0x8180.

mfd: rk808: Prepare rk805 for poweroff RK805 has SLEEP signal, which can put the device into SLEEP or OFF mode. The default is SLEEP mode. However, when the kernel performs power-off (actually the ATF) the device will not go fully off and this will result in higher power consumption and inability to wake the device with RTC alarm. The solution is to enable pm_power_off_prepare function, which will configure SLEEP pin for OFF function.

regulator: rk808: Add RK809 and RK817 support. Add support for the rk809 and rk817 regulator driver. Their specifications are as follows: 1. The RK809 and RK809 consist of 5 DCDCs, 9 LDOs and have the same registers for these components except dcdc5. 2. The dcdc5 is a boost dcdc for RK817 and is a buck for RK809. 3. The RK817 has one switch but The Rk809 has two. The output voltages are configurable and are meant to supply power to the main processor and other components.
