| | | | | | | | | | | | | | | | | | Move the initialization regcache related fields of the regmap struct to regcache_init. This allows us to keep regmap and regcache code better separated.

| | * | regmap: Report if we actually handled an interrupt in regmap-irqMark Brown2011-11-281-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While the IRQ core doesn't currently support shared threaded interrupts that's no reason for drivers not to do their bit and report IRQ_NONE when they don't get an interrupt. This allows the core spurious/wedget interrupt detection support to do its thing. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
| | * | regmap: Add a reusable irq_chip for regmap based interrupt controllersMark Brown2011-11-083-0/+288

This won't cover everything but it's a good start. Each chip supplies a base for the status registers, a base for the mask registers, an optional base for writing acknowledgements (which may be the same as the status registers) and an array of bits within each of these register banks which indicate the interrupt. There is an assumption that the bit for each interrupt will be the same in each of the register bank. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The different devices handled by the WM8994 can be distinguished using their ID registers so we don't need to rely on the user having registered the device correctly. Instead do the initial regmap setup with a minimal configuration only supporting physical I/O and then configure the cache once we have identified the device.

| | * | regmap: Allow drivers to reinitialise the register cache at runtimeMark Brown2011-12-051-0/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sometimes the register map information may change in ways that drivers can discover at runtime. For example, new revisions of a device may add new registers. Support runtime discovery by drivers by allowing the register cache to be reinitialised with a new function regmap_reinit_cache() which discards the existing cache and creates a new one.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Describe the register map to the regmap core so that we can use its diagnostic features and cache support. This is split out from the patch using it due to the size so that the actual code change is a bit clearer. As the various devices are supersets of each other the access maps are built up by layering the functions on top of each other, though the interface for specifying the register defaults isn't currently amenable to this.

Further, interrupts might have been pending on another CPU, so device callback might get invoked after reset. This conflicts with how drivers use reset, which is typically: reset unregister a callback running after reset completed can race with unregister, potentially leading to use after free bugs. Fix by flushing out the write, and flushing pending interrupts. This assumes that device is never reset from its vq/config callbacks, or in parallel with being added/removed, document this assumption. Signed-off-by: Michael S.

To address this issue make find_root_bridges() ignore PCIe root complexes with PCIe native hotplug enabled and make add_bridge() return error code if PCIe native hotplug is enabled for the given root port. This causes acpiphp to refuse to load if PCIe native hotplug is enabled for all complexes and to refuse binding to the root complexes with PCIe native hotplug is enabled.

VDD1/2 currently have it as zero, so regulator_set_voltage won't work for VDD1/2. Update count (n_voltages) for VDD1/2. Output Voltage = (step value * 12.5 mV + 562.5 mV) * gain With above expr, number of voltages that can be selected is step value count * gain count constant for gain count will be called VDD1_2_NUM_VOLT_COARSE existing constant for step value count is VDD1_2_NUM_VOLTS, use VDD1_2_NUM_VOLT_FINE instead to make clear that step value is not the only component in deciding selectable voltage count Signed-off-by: Afzal Mohammed <afzal@ti.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

This caused a black screen even after the backlight is enabled again. It should return the internal backlight_level instead, so that it won't be influenced by the backlight-enable state.
