regmap: mmio: add register clock support

2013-02-14T16:40:28Z

Some mmio devices have a dedicated interface clock that needs to be enabled to access their registers. This patch optionally enables a clock before accessing registers in the regmap_bus callbacks. I added (devm_)regmap_init_mmio_clk variants of the init functions that have an added clk_id string parameter. This is passed to clk_get to request the clock from the clk framework.

regmap: Add asynchronous I/O support

2013-01-29T04:14:52Z

Some use cases like firmware download can transfer a lot of data in quick succession. With high speed buses these use cases can benefit from having multiple transfers scheduled at once since this allows the bus to minimise the delay between transfers. Support this by adding regmap_raw_write_async(), allowing raw transfers to be scheduled, and regmap_async_complete() to wait for them to finish. Signed-off-by: Mark Brown

regmap: Add "no-bus" option for regmap API

2013-01-29T03:42:49Z

This commit adds provision for "no-bus" usage of the regmap API. In this configuration user can provide API with two callbacks 'reg_read' and 'reg_write' which are to be called when reads and writes to one of device's registers is performed. This is useful for devices that expose registers but whose register access sequence does not fit the 'bus' abstraction. Signed-off-by: Andrey Smirnov Signed-off-by: Mark Brown

regmap: irq: Support wake IRQ mask inversion

2013-01-04T20:53:44Z

Support devices which have an enable rather than mask register for wake sources. Signed-off-by: Mark Brown

regmap: flat: Add flat cache type

2013-01-02T10:58:53Z

While for I2C and SPI devices the overhead of using rbtree for devices with only one block of registers is negligible the same isn't always going to be true for MMIO devices where the I/O costs are very much lower. Cater for these devices by adding a simple flat array type for them where the lookups are simple array accesses, taking us right back to the original ASoC cache implementation. Thanks to Magnus Damm for the discussion which prompted this. Signed-off-by: Mark Brown
