mfd: intel-lpss: Fix Intel Elkhart Lake LPSS I2C input clock

2020-03-30T06:35:28Z

Intel Elkhart Lake LPSS I2C has 100 MHz input clock instead of 133 MHz that was our preliminary information. This will result slower I2C bus clock when driver calculates its timing parameters in case ACPI tables don't provide them. Slower I2C bus clock is allowed but let's fix this to match with reality. While at it, keep the same default I2C device properties as Intel Broxton since it is not known do they need any update.

mfd: aat2870: Use scnprintf() for avoiding potential buffer overflow

2020-03-30T06:35:28Z

There is still one call of sprintf() without checking the proper buffer overflow in aat2870_dump_reg(). Replace it with scnprintf() call for covering that. Signed-off-by: Takashi Iwai Signed-off-by: Lee Jones

mfd: dln2: Allow to be enumerated via ACPI

2020-03-30T06:35:28Z

On some platforms user may want to enumerate DLN2 device, its children, to be enumerated via ACPI. In order to achieve this, let's distinguish children by _ADR value. Signed-off-by: Andy Shevchenko Signed-off-by: Lee Jones

mfd: da9062: Add support for interrupt polarity defined in device tree

2020-03-30T06:35:28Z

The da9062 interrupt handler cannot necessarily be low active. Add a function to configure the interrupt type based on what is defined in the device tree. The allowable interrupt type is either low or high level trigger. Signed-off-by: Shreyas Joshi Reviewed-by: Linus Walleij Reviewed-by: Adam Thomson Signed-off-by: Lee Jones

mfd: dln2: Fix sanity checking for endpoints

2020-03-30T06:35:28Z

While the commit 2b8bd606b1e6 ("mfd: dln2: More sanity checking for endpoints") tries to harden the sanity checks it made at the same time a regression, i.e. mixed in and out endpoints. Obviously it should have been not tested on real hardware at that time, but unluckily it didn't happen. So, fix above mentioned typo and make device being enumerated again. While here, introduce an enumerator for magic values to prevent similar issue to happen in the future.

mfd: intel-lpss: Add Intel Comet Lake PCH-V PCI IDs

2020-03-30T06:35:28Z

Intel Comet Lake PCH-V has the same LPSS than Intel Kaby Lake. Add the new IDs to the list of supported devices. Signed-off-by: Andy Shevchenko Signed-off-by: Lee Jones

mfd: sc27xx: Add USB charger type detection support

2020-03-30T06:35:28Z

The Spreadtrum SC27XX series PMICs supply the USB charger type detection function, and related registers are located on the PMIC global registers region, thus we implement and export this function in the MFD driver for users to get the USB charger type.

mfd: rk808: Convert RK805 to shutdown/suspend hooks

2020-03-30T06:35:28Z

RK805 has the same kind of dual-role sleep/shutdown pin as RK809/RK817, so it makes little sense for the driver to have to have two completely different mechanisms to handle essentially the same thing. Move RK805 over to the shutdown/suspend flow to clean things up. Signed-off-by: Robin Murphy Signed-off-by: Lee Jones

mfd: rk808: Reduce shutdown duplication

2020-03-30T06:35:27Z

Rather than having 3 almost-identical functions plus the machinery to keep track of them, it's far simpler to just dynamically select the appropriate register field per variant. Signed-off-by: Robin Murphy Signed-off-by: Lee Jones

mfd: rk808: Stop using syscore ops

2020-03-30T06:35:27Z

Setting the SLEEP pin to its shutdown function for appropriate PMICs doesn't need to happen in single-CPU context, so there's really no point involving the syscore machinery. Hook it up to the standard driver model shutdown method instead. This also obviates the issue that the syscore ops weren't being unregistered on probe failure or module removal.
