regmap: cache: Fall back to register by register read for cache defaults

2016-02-02T17:58:22Z

If we are unable to read the cache defaults for a regmap then fall back on attempting to read them word by word. This is going to be painfully slow for large regmaps but might be adequate for smaller ones.

regmap: pass buffer size to regmap_raw_read() in regcache_hw_init()

2016-01-15T18:14:14Z

regcache_hw_init() uses regmap_raw_read() to initialize cache when reg_defaults_raw isn't provided. The last parameter to regmap_raw_read() is buffer size in bytes, however regcache_hw_init() called it with number of registers to read instead, which cause problem if they aren't one byte wide in cache. This wasn't triggered by any of current in-tree drivers since they either have one-byte registers or provide reg_defaults_raw explicitly. Signed-off-by: Maciej S. Szmigiero Signed-off-by: Mark Brown

regmap: cache: Move the num_reg_defaults check as early as possible

2015-12-12T22:37:06Z

If the register defaults are provided by the driver without the number by mistake, it should just return an error with one promotion. This should be as early as possible, then there is no need to verify the register defaults' stride and the other code followed. Signed-off-by: Xiubo Li Signed-off-by: Mark Brown

regmap: cache: Add warning info for the cache check

2015-12-12T22:37:06Z

If there is no cache used for the drivers, the register defaults or the register defaults raw are not need any more. This patch will check this and print a warning. Signed-off-by: Xiubo Li Signed-off-by: Mark Brown

regmap: cache: Add 64-bit mode support

2015-12-09T20:39:22Z

Since the mmio has support the 64-bit has been supported for the 64-bit platform, so should the regcache core too. Signed-off-by: Xiubo Li Signed-off-by: Mark Brown

regmap: cache: To suppress the noise of checkpatch

2015-12-09T20:39:22Z

There will be some warning like the following when checking new patches near this code: "WARNING: Missing a blank line after declarations" This patch will suppress this warning. Signed-off-by: Xiubo Li Signed-off-by: Mark Brown

debugfs: Pass bool pointer to debugfs_create_bool()

2015-10-04T10:36:07Z

Its a bit odd that debugfs_create_bool() takes 'u32 *' as an argument, when all it needs is a boolean pointer. It would be better to update this API to make it accept 'bool *' instead, as that will make it more consistent and often more convenient. Over that bool takes just a byte. That required updates to all user sites as well, in the same commit updating the API. regmap core was also using debugfs_{read|write}_file_bool(), directly and variable types were updated for that to be bool as well.
