regmap: Add support for register indirect addressing.

2012-06-17T20:34:18+00:00

Devices with register paging or indirectly accessed registers can configure register mapping to map those on virtual address range. During access to virtually mapped register range, indirect addressing is processed automatically, in following steps: 1. selector for page or indirect register is updated (when needed); 2. register in data window is accessed. Configuration should provide minimum and maximum register for virtual range, details of selector field for page selection, minimum and maximum register of data window for indirect access. Virtual range registers are managed by cache as well as direct access registers. In order to make indirect access more efficient, selector register should be declared as non-volatile, if possible. struct regmap_config is extended with the following: struct regmap_range_cfg *ranges; unsigned int n_ranges; [Also reordered debugfs init to later on since the cleanup code was conflicting with the new cleanup code for ranges anyway -- broonie] Signed-off-by: Krystian Garbaciak Signed-off-by: Mark Brown

regmap: Remove warning on stubbed dev_get_regmap()

2012-06-13T15:37:43+00:00

It's perfectly sensible to ask if there's a regmap for a device which doesn't have one so the stubbed version shouldn't complain, the caller should be prepared for this. Signed-off-by: Mark Brown

regmap: Implement support for wake IRQs

2012-06-05T13:38:20+00:00

Allow chips to provide a bank of registers for controlling the wake state in a similar fashion to the masks and propagate the wake count to the parent interrupt controller. Signed-off-by: Mark Brown

regmap: Constify regmap_irq_chip

2012-06-03T12:16:51+00:00

We should never be modifying it and it lets drivers declare it const. Signed-off-by: Mark Brown

regmap: allow busses to request formatting with specific endianness

2012-06-03T12:11:43+00:00

Add a field to struct regmap_bus that allows bus drivers to request that register addresses and values be formatted with a specific endianness. The default endianness is unchanged from current operation: Big. Implement native endian formatting/parsing for 16- and 32-bit values. This will be enough to support regmap-mmio.c.

regmap: add support for non contiguous status to regmap-irq

2012-05-14T16:40:05+00:00

In some chips the IRQ status registers are not contiguous in the register map but spaced at even spaces. This is an easy case to handle with minor changes. It is assume for this purpose that the stride for status is equal to the stride for mask/ack registers as well. Signed-off-by: Graeme Gregory Signed-off-by: Mark Brown

regmap: Convert regmap_irq to use irq_domain

2012-05-13T18:25:59+00:00

This gets us up to date with the recommended current kernel infrastructure and should transparently give us device tree interrupt bindings for any devices using the framework. If an explicit IRQ mapping is passed in then a legacy interrupt range is created, otherwise a simple linear mapping is used. Previously a mapping was mandatory so existing drivers should not be affected. A function regmap_irq_get_virq() is provided to allow drivers to map individual IRQs which should be used in preference to the existing regmap_irq_chip_get_base() which is only valid if a legacy IRQ range is provided.

regmap: Implement dev_get_regmap()

2012-05-08T17:19:15+00:00

Use devres to implement dev_get_regmap(). This should mean that in almost all cases devices wishing to take advantage of framework features based on regmap shouldn't need to explicitly pass the regmap into the framework. This simplifies device setup a bit. Signed-off-by: Mark Brown
