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: Export regmap_reinit_cache()

2012-06-07T21:57:21Z

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

regmap: Fix the size calculation for map->format.buf_size

2012-06-03T12:14:01Z

The word to be transmitted/received via regmap is composed by the following parts: config->reg_bits config->val_bits config->pad_bits ,so the total size should be calculated by summing up the number of bits of each element and using a DIV_ROUND_UP to return the number of bytes.

regmap: clean up debugfs if regmap_init fails

2012-06-03T12:13:38Z

If debugfs isn't cleaned up, stale files will be left in the filesystem which will cause an OOPS when accessed the first time, and hang the accessing application when accessed again, presumably due to some lock being left held. Signed-off-by: Stephen Warren Signed-off-by: Mark Brown

regmap: allow busses to request formatting with specific endianness

2012-06-03T12:11:43Z

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.
