regmap: fix page selection for noinc writes

2020-09-21T19:58:02Z

Non-incrementing writes can fail if register + length crosses page border. However for non-incrementing writes we should not check for page border crossing. Fix this by passing additional flag to _regmap_raw_write and passing length to _regmap_select_page basing on the flag.

regmap: add proper SPDX identifiers on files that did not have them.

2019-04-25T19:22:15Z

There were a few files in the regmap code that did not have SPDX identifiers on them, so fix that up. At the same time, remove the "free form" text that specified the license of the file, as that is impossible for any tool to properly parse. Also, as Mark loves // comment markers, convert all of the headers to be the same to make things look consistent :) Signed-off-by: Greg Kroah-Hartman Signed-off-by: Mark Brown

regmap: make LZO cache optional

2017-06-06T18:46:57Z

Commit 2cbbb579bcbe3 ("regmap: Add the LZO cache support") added support for LZO compression in regcache, but there were never any users added afterwards. Since LZO support itself has its own size, it currently is rather a deoptimization. So make it optional by introducing a symbol that can be selected by drivers wanting to make use of it. Saves e.g. ~46 kB on MIPS (size of LZO support + regcache LZO code). Signed-off-by: Jonas Gorski Signed-off-by: Mark Brown

regmap: Fixup the kernel-doc comments on functions/structures

2017-01-12T17:22:48Z

Most of the kernel-doc comments in regmap don't actually generate correctly. This patch fixes up a few common issues, corrects some typos and adds some missing argument descriptions. The most common issues being using a : after the function name which causes the short description to not render correctly and not separating the long and short descriptions of the function. There are quite a few instances of arguments not being described or given the wrong name as well. This patch doesn't fixup functions/structures that are currently missing descriptions.

regmap: cache: Fix num_reg_defaults computation from reg_defaults_raw

2016-07-29T22:02:19Z

In 3245d460 (regmap: cache: Fall back to register by register read for cache defaults) non-readable registers are skipped when initializing reg_defaults, but are still included in num_reg_defaults. So there can be uninitialized entries at the end of reg_defaults, which can cause problems when the register cache initializes from the full array. Fixed it by excluding non-readable registers from the count as well. Signed-off-by: Maarten ter Huurne Signed-off-by: Mark Brown

regmap: cache: Fix typo in cache_bypass parameter description

2016-03-23T18:12:39Z

Setting the flag 'cache_bypass' will bypass the cache not the hardware. Fix this comment here. Fixes: 0eef6b0415f5 ("regmap: Fix doc comment") Signed-off-by: Andrew F. Davis Signed-off-by: Mark Brown

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.
