regmap: Add hook for printk logging for debugging during early init

2012-07-06T13:16:16Z

Sometimes for failures during very early init the trace infrastructure isn't available early enough to be used. For this sort of problem defining LOG_DEVICE will add printks for basic register I/O on a specific device, allowing trace to be extracted when the trace system doesn't come up early enough to work with.

regmap: Fix work_buf switching for page update during virtual range access.

2012-06-19T09:42:56Z

After page update, orginal work_buf has to be restored regardless of the result. Signed-off-by: Krystian Garbaciak Signed-off-by: Mark Brown

regmap: Add support for register indirect addressing.

2012-06-17T20:34:18Z

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: Move lock out from internal function _regmap_update_bits().

2012-06-17T20:30:39Z

Locks are moved to regmap_update_bits(), which allows to reenter internal function _regmap_update_bits() from inside of regmap read/write routines. Signed-off-by: Krystian Garbaciak Signed-off-by: Mark Brown

regmap: mmio: Staticize regmap_mmio_gen_context()

2012-06-13T18:15:11Z

regmap_mmio_gen_context() is only used in regmap-mmio.c. Thus make it static. Signed-off-by: Axel Lin Acked-by: Stephen Warren Signed-off-by: Mark Brown

regmap: Export regmap_reinit_cache()

It's supposed to be there for drivers. Signed-off-by: Mark Brown

regmap: Implement support for wake IRQs

2012-06-05T13:38:20Z

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: Don't try to map non-existant IRQs

2012-06-05T13:38:20Z

If the driver supplied an empty entry in the array of IRQs then return an error rather than trying to do the mapping. This is intended for use with handling chip variants and similar situations. Signed-off-by: Mark Brown
