mfd: sec-core: Cleanup formatting to a consistent style

2019-02-18T09:07:17Z

Cleanup the formatting to have consistent style across the file (only white-space issues). No expected difference in code. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Lee Jones

mfd: sec-core: Return gracefully instead of BUG() if device cannot match

2019-02-07T10:43:15Z

Replace impossible BUG() in probe with a proper return. This can be triggered only in case of a clear bug (e.g. adding broken half-support for new S2MPSXX flavor) but BUG() is discouraged and the boot process can actually try to continue. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Lee Jones

mfd: sec-core: Add SPDX license identifiers

mfd: sec-core: Export OF module alias table

2018-07-27T08:27:15Z

In case of Device Tree platforms, even though the Samsung PMIC sec device is instantiated from DT, the driver is still matched through I2C module alias. That is because I2C core always reports an I2C module alias instead of DT one. This could change in the future so export DT module alias. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Lee Jones

mfd: sec: Use devm_mfd_add_devices and devm_regmap_add_irq_chip

2016-05-09T12:27:38Z

Use devm_mfd_add_devices() for adding MFD child devices and devm_regmap_add_irq_chip() for IRQ chip registration. This reduces the error code path and .remove callback for removing MFD child devices and deleting IRQ chip data.

mfd: sec-core: Rename MFD and regulator names differently

2015-11-24T11:11:16Z

Currently S2MPSXX multifunction device is named as *-pmic, and these MFDs also supports regulator as a one of its MFD cell which has the same name, because current name is confusing and we want to sort it out. We did discussed different approaches about how the MFD and it cells need to be named here [1]. Based in the discussion this patch rename MFD regulator name as *-regulator instead of current *-pmic. This patch also changes the corresponding entries in the regulator driver to keep git-bisect happy.

mfd: sec: Add support for S2MPS15 PMIC

2015-11-23T10:33:16Z

Add support for S2MPS15 PMIC which is similar to S2MPS11 PMIC. The S2MPS15 PMIC supports 27 LDO regulators, 10 buck regulators, RTC, three 32.768KHz clock outputs and battery charger. This patch adds initial support for LDO and buck regulators of S2MPS15 device.

mfd: sec-core: Remove unused s2mpu02-rtc and s2mpu02-clk children

2015-10-30T18:57:38Z

The commit 54e8827d5f0e ("mfd: sec-core: Add support for S2MPU02 device") added new MFD child devices for S2MPU02: RTC and clock provider (the clock provider with new compatible). However support for these devices was not added to existing drivers (rtc-s5m, clk-s2mps11). New drivers were not submitted neither. This means that the name of children devices is completely unused. The "samsung,s2mpu02-clk" compatible remains undocumented so it is unclear what is provided by that compatible. Clean up this by removing unused child devices and undocumented compatible.

mfd: sec-core: Disable buck voltage reset on watchdog falling edge

2015-10-30T17:20:37Z

The WRSTBI bit (disabled by default but enabled by bootloader), when set, is responsible for resetting voltages to default values of certain bucks on falling edge of Warm Reset Input pin from AP. However on some boards (with S2MPS13) the pin is pulled down so any suspend will effectively trigger the reset of bucks supplying the power to the little and big cores. In the same time when resuming, these bucks must provide voltage greater or equal to voltage before suspend to match the frequency chosen by cpufreq. If voltage (default value of voltage after reset) is lower than one set by cpufreq before suspend, then system will hang during resuming.
