It is found for instance in the samsung,coreprimevelte smartphone with which this was tested. Only implement basic support to allow for the use of regulators and onkey omitting the currently unused register definitions and I2C subclients which should thus be added with the subdevice drivers which need them. The register mapping and functions of 88PM886 are very similar to those of 88PM880 and the downstream version of the driver handles both of these devices. Possible future efforts to support 88PM880 should thus make use of this driver. Signed-off-by: Karel Balej --- Notes: RFC v2: - Remove some abstraction. - Sort includes alphabetically and add linux/of.h. - Depend on OF, remove of_match_ptr and add MODULE_DEVICE_TABLE. - Use more temporaries and break long lines. - Do not initialize ret in probe. - Use the wakeup-source DT property. - Rename ret to err. - Address Lee's comments: - Drop patched in presets for base regmap and related defines. - Use full sentences in comments. - Remove IRQ comment. - Define regmap_config member values. - Rename data to sys_off_data. - Add _PMIC suffix to Kconfig. - Use dev_err_probe. - Do not store irq_data. - s/WHOAMI/CHIP_ID - Drop LINUX part of include guard name. - Merge in the regulator series modifications in order to have more devices and modify the commit message accordingly. Changes with respect to the original regulator series patches: - ret -> err - Add temporary for dev in pm88x_initialize_subregmaps. - Drop of_compatible for the regulators. - Do not duplicate LDO regmap for bucks. - Rewrite commit message. drivers/mfd/88pm88x.c | 211 ++++++++++++++++++++++++++++++++++++ drivers/mfd/Kconfig | 12 ++ drivers/mfd/Makefile | 1 + include/linux/mfd/88pm88x.h | 46 ++++++++ 4 files changed, 270 insertions(+) create mode 100644 drivers/mfd/88pm88x.c create mode 100644 include/linux/mfd/88pm88x.h diff --git a/drivers/mfd/88pm88x.c b/drivers/mfd/88pm88x.c new file mode 100644 index 000000000000..301e3e8f26f4 --- /dev/null +++ b/drivers/mfd/88pm88x.c @@ -0,0 +1,211 @@ +// SPDX-License-Identifier: GPL-2.0-only +#include +#include +#include +#include +#include +#include +#include + +#include + +#define PM88X_REG_INT_STATUS1 0x05 + +#define PM88X_REG_INT_ENA_1 0x0a +#define PM88X_INT_ENA1_ONKEY BIT(0) + +#define PM88X_REGMAP_CONF_REG_BITS 8 +#define PM88X_REGMAP_CONF_VAL_BITS 8 +#define PM88X_REGMAP_CONF_MAX_REG 0xfe + +enum pm88x_irq_number { + PM88X_IRQ_ONKEY, + + PM88X_MAX_IRQ +};
