regmap: add support for 7/17 register formating

2021-05-26T11:16:17+00:00

This patch adds support for 7 bits register, 17 bits value type register
formating. This is used, for example, by the Analog Devices
ADMV1013/ADMV1014.

regmap-i2c: Set regmap max raw r/w from quirks

2021-05-14T12:25:03+00:00

Set regmap raw read/write from i2c quirks max read/write
so regmap_raw_read/write can split the access into chunks

regmap: Fix order of regmap write log

2020-11-12T16:05:17+00:00

_regmap_write can trigger a _regmap_select_page, which will call
another _regmap_write that will be executed first, but the log shows
the inverse order

Also, keep consistency with _regmap_read which only logs in case of
success

regmap: Add a bulk field API

Useful for devices with many fields.

regmap: add support to regmap_field_bulk_alloc/free apis

2020-09-28T19:50:03+00:00

Usage of regmap_field_alloc becomes much overhead when number of fields
exceed more than 3.
QCOM LPASS driver has extensively converted to use regmap_fields.

Using new bulk api to allocate fields makes it much more cleaner code to read!

regmap: destroy mutex (if used) in regmap_exit()

2020-09-28T17:28:45+00:00

While not destroying mutexes doesn't lead to memory leaks, it's still
the correct thing to do for mutex debugging accounting.

regmap: debugfs: Fix more error path regressions

2020-09-21T23:11:45+00:00

Many error paths in __regmap_init rely on ret being pre-initialised to
-EINVAL, add an extra initialisation in after the new call to
regmap_set_name.

regmap: fix page selection for noinc writes

2020-09-21T19:58:02+00:00

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.
