regmap: no need primary handler for nested irq

2012-09-09T03:05:45Z

The primary handler will NOT be called if the interrupt nests into another interrupt thread. Remove it to avoid confusing. Signed-off-by: Yunfan Zhang Signed-off-by: Mark Brown

regmap: irq: Add mask invert flag for enable register

2012-08-30T18:13:41Z

Currently, regmap will write 1 to mask_base to mask an interrupt and write 0 to unmask it. But some chips do not have an interrupt mask register, and only have interrupt enable register. Then we should write 0 to disable interrupt and 1 to enable. So add an mask_invert flag to handle this. If it is not set, behavior is same as previous. If set it to 1, the mask value will be inverted before written to mask_base Signed-off-by: Xiaofan Tian Signed-off-by: Mark Brown

regmap: irq: Enable devices for runtime PM while handling interrupts

2012-08-07T19:29:45Z

Some devices need to have a runtime PM reference while handling interrupts to ensure that the register I/O is available. Support this with a flag in the chip. Signed-off-by: Mark Brown

regmap: irq: initialize all irqs to wake disabled

2012-08-04T11:13:54Z

The kerneldoc for irq_set_irq_wake() says: Enable/disable power management wakeup mode, which is disabled by default. regmap_irq_set_wake() clears bits to enable wake for an interrupt, and sets bits to disable wake. Hence, we should set all bits in wake_buf initially, to mirror the expected disabled state. Signed-off-by: Stephen Warren Signed-off-by: Mark Brown

regmap: set MASK_ON_SUSPEND/SKIP_SET_WAKE if no wake_base

2012-08-04T11:13:53Z

If a regmap-irq chip has no wake base: * There's no point calling .irq_set_wake, hence IRQCHIP_SKIP_SET_WAKE. * If some IRQs in the chip are enabled for wake and some aren't, we should mask those interrupts that are not wake enabled, so that if they occur during suspend, the system is not awoken. Hence, IRQCHIP_MASK_ON_SUSPEND. Note that IRQCHIP_MASK_ON_SUSPEND is handled by check_wakeup_irqs(), which always iterates over every single interrupt in the system, irrespective of whether an interrupt is a child of a controller whose output interrupt has no wake-enabled inputs and hence is presumably masked itself. Hence this change might cause interrupt unnecessary masking operations and associated register I/O. Signed-off-by: Stephen Warren Signed-off-by: Mark Brown

regmap: name irq_chip based on regmap_irq_chip's name

2012-08-04T11:13:53Z

This is intended to give each irq_chip a useful name, rather than hard- coding them all as "regmap". Signed-off-by: Stephen Warren Signed-off-by: Mark Brown

regmap: store irq_chip inside regmap_irq_chip_data

2012-08-04T11:13:53Z

This will allow later patches to adjust portions of the irq_chip individually for each regmap_irq_chip that is created. Signed-off-by: Stephen Warren Signed-off-by: Mark Brown

regmap: irq: Only update mask bits when doing initial mask

2012-08-04T11:13:53Z

Don't write the full register, it's possible there's bits other than the masks in the same register which we shouldn't be changing. Signed-off-by: Mark Brown Tested-by: Stephen Warren

regmap: fix some error messages to take account of irq_reg_stride

2012-08-04T11:13:53Z

A number of places in the code were printing error messages that included the address of a register, but were not calculating the register address in the same way as the access to the register. Use a temporary to solve this. Signed-off-by: Stephen Warren Signed-off-by: Mark Brown
