mfd: s2mps11: Add manual shutdown method for Odroid XU3 On Odroid XU3 board (with S2MPS11 PMIC) the PWRHOLD bit in CTRL1 register must be manually set to 0 before initiating power off sequence. One of usual power down methods for Exynos based devices looks like: 1. PWRHOLD pin of PMIC is connected to PSHOLD of Exynos SoC. 2. Exynos holds up this pin during system operation. 3. ACOKB pin of PMIC is pulled up to VBATT and optionally to pin in other device. 4. When PWRHOLD/PSHOLD goes low, the PMIC will turn off the power if ACOKB goes high. On Odroid XU3 family the difference is in (3) - the ACOKB is grounded. This means that PMIC must manually set PWRHOLD field to low and then wait for signal from Application Processor (the usual change in PWRHOLD/PSHOLD pin will actually cut off the power). The patch adds respective binding allowing Odroid XU3 device to be powered off.

This could be observed in various hangs, e.g. in infinite loop during waiting for UDR field change. On this chip family the RTC has different I2C address than PMIC so additional regmap is needed.

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.

When device is woken up from suspend by RTC Alarm, an interrupt occurs before resuming I2C bus controller. The interrupt is handled by regmap_irq_thread which tries to read RTC registers. This read fails (I2C is still suspended) and RTC Alarm interrupt is disabled. Disable the S5M8767 interrupts during suspend (disable_irq()) and enable them during resume so the device will be still woken up but the interrupt won't happen before resuming I2C bus.

mfd: s2mps11: Add manual shutdown method for Odroid XU3 On Odroid XU3 board (with S2MPS11 PMIC) the PWRHOLD bit in CTRL1 register must be manually set to 0 before initiating power off sequence. One of usual power down methods for Exynos based devices looks like: 1. PWRHOLD pin of PMIC is connected to PSHOLD of Exynos SoC. 2. Exynos holds up this pin during system operation. 3. ACOKB pin of PMIC is pulled up to VBATT and optionally to pin in other device. 4. When PWRHOLD/PSHOLD goes low, the PMIC will turn off the power if ACOKB goes high. On Odroid XU3 family the difference is in (3) - the ACOKB is grounded. This means that PMIC must manually set PWRHOLD field to low and then wait for signal from Application Processor (the usual change in PWRHOLD/PSHOLD pin will actually cut off the power). The patch adds respective binding allowing Odroid XU3 device to be powered off.

These macros allow the suspend and resume functions to be automatically dropped by the compiler when CONFIG_SUSPEND is disabled, without having to use #ifdef guards. This has the advantage of always compiling these functions in, independently of any Kconfig option. Thanks to that, bugs and other regressions are subsequently easier to catch.
