| | | | | | | | | | | | | | | | | | | | | | | | Unlike real i2c-devices which get detached from the driver, dummy-devices get truly unregistered. So, there has never been a need to clear the clientdata because the device will go away anyhow.

| | | | | | | | | | | | | | | | | | | | | | | | The rdc321x southbridge PCI device has no MEM PCI resources that we could pass to mfd_add_devices. Since 33254dd5, mfd_add_device checks for the mem_base argument that we set to NULL. Changing the resources passed to our MFD cells from IORESOURCE_MEM to IORESOURCE_IO fixes that. Since we use those resources as offsets to the PCI configuration space base address of the southbridge device this is also more adequate.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The interface for the AB3100 is changed to make way for the ABX500 family of chips: AB3550, AB5500 and future ST-Ericsson Analog Baseband chips. The register access functions are moved out to a separate struct abx500_ops. In this way the interface is moved from the implementation and the sub functionality drivers can keep their interface intact when chip infrastructure and communication mechanisms changes. We also define the AB3550 device IDs and the AB3550 platform data struct and convert the catenated 32bit event to an array of 3 x 8bits.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | There're two IRQ pins output from MAX8925. One is PMIC interrupt, the other is TSC interrupt. But they're sharing one irq chip. After initializing MAX8925 interrupts, unexpected TSC interrupt may occur and it can't be cleared if touch driver isn't loaded. Now move the operation of masking TSC interrupt behind requesting PMIC interrupt. If touch driver isn't loaded, this interrupt is always masked.

| * mfd: Ensure WM831x charger interrupts are acknowledged when suspendingMark Brown2010-05-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The charger interrupts on the WM831x are unconditionally a wake source for the system. If the power driver is not able to monitor them (for example, due to the IRQ line not having been wired up on the system) then any charger interrupt will prevent the system suspending for any meaningful amount of time since nothing will ack them. Avoid this issue by manually acknowledging these interrupts when we suspend the WM831x core device if they are masked. If software is actually using the interrupts then they will be unmasked and this change will have no effect.

| | | | | | | | | | | | | | | | | | | | | | Ensure that the hardware has interrupts masked if we are not using the interrupt controller on the WM831x by initialising the masks before we check for the setup data required for the IRQ line.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently completion of WM831x AUXADC conversions is monitored by checking for convertor enable. Due to the mechanism used to ensure data corruption is avoided when reading AUXADC data there may under heavy I/O be a window where this bit has cleared but the conversion results have not been updated. Data availability is only guaranteed after the AUXADC data interrupt has been asserted. Avoid this by always using the interrupt to detect completion. If the chip IRQ is not set up then we poll the IRQ status register for up to 5ms. If it is set up then we rely on the data done interrupt with a vastly increased timeout, failing the conversion if the interrupt is not generated. This also saves a register read when using interrupts. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
