regmap: Support some block operations on cached devices

2011-10-13T10:41:54+00:00

Support raw reads if all the registers being read are volatile, the cache will have no impact for tem. Support bulk reads either directly (if all the registers are volatile) or by falling back to iterating over single register reads otherwise. Signed-off-by: Mark Brown

regmap: Warn on raw I/O as well as bulk reads that bypass cache

2011-10-10T09:24:33+00:00

As with the bulk reads we really should be able to make these play nicely with the cache but warn for now. Signed-off-by: Mark Brown Acked-by: Dimitris Papastamos

regmap: Make _regmap_write() global

regmap: Incorporate the regcache core into regmap

2011-09-19T18:06:35+00:00

This patch incorporates the regcache core code into regmap. All previous patches have been no-ops essentially up to this point. The bulk read operation is not supported by regcache at the moment. This will be implemented incrementally. Signed-off-by: Dimitris Papastamos Tested-by: Lars-Peter Clausen Signed-off-by: Mark Brown

regmap: Add support for device specific write and read flag masks.

2011-09-05T21:55:57+00:00

Some buses like SPI have no standard notation of read or write operations. The general scheme here is to set or clear specific bits in the register address to indicate whether the operation is a read or write. We already support having a read flag mask per bus, but as there is no standard the bits which need to be set or cleared differ between devices and vendors, thus we need a mechanism to specify them per device. This patch adds two new entries to the regmap_config struct, read_flag_mask and write_flag_mask. These will be or'ed onto the top byte when doing a read or write operation. If both masks are empty the device will fallback to the regmap_bus masks. Signed-off-by: Lars-Peter Clausen Signed-off-by: Mark Brown

Merge branch 'regmap-linus' into regmap-next

regmap: Remove bitrotted module_put()s

2011-09-05T17:55:58+00:00

The conversion to per bus type registration functions means we don't need to do module_get()s to hold the bus types in memory (their users will link to them) so we removed all those calls. This left module_put() calls in the cleanup paths which aren't needed and which cause unbalanced puts if we ever try to unload anything. Reported-by: Jonathan Cameron Signed-off-by: Mark Brown

regmap: Add functions to check for access on registers

2011-08-14T10:51:11+00:00

We're going to be using these in quite a few places so factor out the readable/writable/volatile/precious checks. Signed-off-by: Mark Brown

regmap: Skip precious registers when dumping registers via debugfs

regmap: Provide register map dump via debugfs

2011-08-08T06:57:00+00:00

Copy over the read parts of the ASoC debugfs implementation into regmap, allowing users to see what the register values the device has are at runtime. The implementation, especially the support for seeking, is mostly due to Dimitris Papastamos' work in ASoC. Signed-off-by: Mark Brown
