rockchip: Add option to prevent booting on power plug-in

2022-06-29T03:42:10Z

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. This patch parallels the work done in the following patch series: https://lore.kernel.org/u-boot/20220121133732.2397273-1-andre.przywara@arm.com/ Signed-off-by: Chris Morgan Reviewed-by: Jaehoon Chung

power: pmic: rk8xx: Support sysreset shutdown method

2022-06-29T03:42:10Z

Add support for sysreset shutdown for this PMIC. The values were pulled from the various datasheets, but for now it has only been tested on the rk817 (for an Odroid Go Advance). Signed-off-by: Chris Morgan Reviewed-by: Jaehoon Chung Reviewed-by: Kever Yang

pmic: pca9450: Add optional SD_VSEL GPIO for LDO5

2022-06-28T13:24:31Z

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. This is a port of the same change in the Linux kernel: 8c67a11bae88 ("regulator: pca9450: Add SD_VSEL GPIO for LDO5") Signed-off-by: Frieder Schrempf Reviewed-by: Fabio Estevam Tested-by: Fabio Estevam

pmic: pca9450: add DM_I2C dependencies in Kconfig

2022-06-14T02:20:50Z

The pca9450 driver uses dm_i2c_{read,write}, which are (unsurprisingly) only available with DM_I2C. Make sure one can't create an unbuildable .config by adding proper dependencies. While here, append "in SPL" to the prompt for the SPL_ variant so it doesn't read the same as the one for the non-SPL_ variant. Signed-off-by: Rasmus Villemoes Reviewed-by: Jaehoon Chung

pmic: pca9450: Add regulator driver

2022-05-20T10:36:48Z

Add PCA9450 regulator driver. This is complementary driver for the BUCKn and LDOn regulators provided by the PCA9450 PMIC driver. Currently the driver permits reading the settngs and configuring the BUCKn and LDOn regulators. Reviewed-by: Fabio Estevam Signed-off-by: Marek Vasut Cc: Fabio Estevam Cc: Peng Fan Cc: Stefano Babic
