The kernel test robot reported the following build error: All errors (new ones prefixed by >>): xtensa-linux-ld: drivers/regulator/qcom-rpmh-regulator.o: in function `rpmh_regulator_vrm_get_voltage_sel': qcom-rpmh-regulator.c:(.text+0x270): undefined reference to `rpmh_write' xtensa-linux-ld: drivers/regulator/qcom-rpmh-regulator.o: in function `rpmh_regulator_send_request': qcom-rpmh-regulator.c:(.text+0x2f2): undefined reference to `rpmh_write' xtensa-linux-ld: drivers/regulator/qcom-rpmh-regulator.o: in function `rpmh_regulator_vrm_get_voltage_sel': >> qcom-rpmh-regulator.c:(.text+0x274): undefined reference to `rpmh_write_async' xtensa-linux-ld: drivers/regulator/qcom-rpmh-regulator.o: in function `rpmh_regulator_send_request': qcom-rpmh-regulator.c:(.text+0x2fc): undefined reference to `rpmh_write_async' Which is due to REGULATOR_QCOM_RPMH depending on QCOM_RPMH || COMPILE_TEST. The problem is that QOM_RPMH can now be a module, which in that case requires REGULATOR_QCOM_RPMH=m to build. However, if COMPILE_TEST is enabled, REGULATOR_QCOM_RPMH can be set to =y while QCOM_RPMH=m which will cause build failures. The fix here is to add (QCOM_RPMH=n && COMPILE_TEST) to the dependency.

2020-09-17Merge series "Support ROHM BD9576MUF and BD9573MUF PMICs" from Matti ↵Mark Brown1-0/+10
Vaittinen <matti.vaittinen@fi.rohmeurope.com>: Initial support for ROHM BD9576MUF and BD9573MUF PMICs. These PMICs are primarily intended to be used to power the R-Car family processors. BD9576MUF includes some additional safety features the BD9573MUF does not have. This initial version of drivers does not utilize these features and for now the SW behaviour is identical. Please note that this version of drivers is only tested on BD9576MUF but according to the data-sheets the relevant parts of registers should be same so drivers should also work on BD9573MUF. This patch series includes MFD, watchdog and regulator drivers with basic functionality such as: - Enabling and pinging the watchdog - configuring watchog timeout / window from device-tree - reading regulator states/voltages - enabling/disabling VOUT1 (VD50) when control mode B is used. This patch series does not bring interrupt support. BD9576MUF and BD9573MUF are designed to keep the IRQ line low for whole duration of error condition. IRQ can't be 'acked'. So proper IRQ support would require some IRQ limiter implementation (delayed unmask?) in order to not hog the CPU. --- Matti Vaittinen (6): dt_bindings: mfd: Add ROHM BD9576MUF and BD9573MUF PMICs dt_bindings: regulator: Add ROHM BD9576MUF and BD9573MUF PMICs mfd: Support ROHM BD9576MUF and BD9573MUF wdt: Support wdt on ROHM BD9576MUF and BD9573MUF regulator: Support ROHM BD9576MUF and BD9573MUF MAINTAINERS: Add ROHM BD9576MUF and BD9573MUF drivers .../bindings/mfd/rohm,bd9576-pmic.yaml | 129 +++++++ .../regulator/rohm,bd9576-regulator.yaml | 33 ++ MAINTAINERS | 4 + drivers/mfd/Kconfig | 11 + drivers/mfd/Makefile | 1 + drivers/mfd/rohm-bd9576.c | 130 +++++++ drivers/regulator/Kconfig | 10 + drivers/regulator/Makefile | 1 + drivers/regulator/bd9576-regulator.c | 337 ++++++++++++++++++ drivers/watchdog/Kconfig | 13 + drivers/watchdog/Makefile | 1 + drivers/watchdog/bd9576_wdt.c | 295 +++++++++++++++ include/linux/mfd/rohm-bd957x.h | 61 ++++ include/linux/mfd/rohm-generic.h | 2 + 14 files changed, 1028 insertions(+) create mode 100644 Documentation/devicetree/bindings/mfd/rohm,bd9576-pmic.yaml create mode 100644 Documentation/devicetree/bindings/regulator/rohm,bd9576-regulator.yaml create mode 100644 drivers/mfd/rohm-bd9576.c create mode 100644 drivers/regulator/bd9576-regulator.c create mode 100644 drivers/watchdog/bd9576_wdt.c create mode 100644 include/linux/mfd/rohm-bd957x.h base-commit: f4d51dffc6c01a9e94650d95ce0104964f8ae822 -- 2.21.0 -- Matti Vaittinen, Linux device drivers ROHM Semiconductors, Finland SWDC Kiviharjunlenkki 1E 90220 OULU FINLAND ~~~ "I don't think so," said Rene Descartes.

2020-01-24regulator: bd718x7: Split driver to common and bd718x7 specific partsMatti Vaittinen1-0/+4
Few ROHM PMICs allow setting the voltage states for different system states like RUN, IDLE, SUSPEND and LPSR. States are then changed via SoC specific mechanisms. bd718x7 driver implemented device-tree parsing functions for these state specific voltages. The parsing functions can be re-used by other ROHM chip drivers like bd71828. Split the generic functions from bd718x7-regulator.c to rohm-regulator.c and export them for other modules to use.

2019-12-17regulator: bd71828: Basic support for ROHM bd71828 PMIC regulatorsMatti Vaittinen1-0/+12
ROHM BD71828 is a power management IC containing 7 bucks and 7 LDOs. Bucks 1,2,6 and 7 can be assigned to a regulator group controlled by run-levels. Eg. Voltages and enable/disable statuses for specific run-levels (run0 to run3) can be set via register interface and run level changes can then be done either via I2C or GPIO. This initial commit does not support assigning bucks to be controlled via run-levels but only allows them to be individually controlled. LDO5 voltage can also be controlled by GPIO2 pin and register interfaces but this driver only supports the control via register.
