[PATCH v5 0/6] iio: adc: meson: add iio channels to read channel 7 mux inputs

From: George Stark
Date: Tue Jul 11 2023 - 16:02:15 EST


Changelog:

v1->v2:
split refactoring patch [1] into 4 smaller patches, fix comment style

[1] https://lore.kernel.org/lkml/20230621062715.455652-2-gnstark@xxxxxxxxxxxxxx/

v2->v3:
remove patch 'meson saradc: unite iio channel array definitions' [1] after discussion

patch 'meson saradc: add enum for iio channel array indexes'
- change enum items prefix from INDEX_ to NUM_ since name 'channel index' is
more relevant to channel array index in iio world and with 2 tables our array index is
not always equal to channel number
- resolve conflicts after deleting [1]
- update commit message, previous patch [2]
- return channel number for temp channel. It wasn't used and isn't used currently
but may need later

patch meson saradc: support reading from channel 7 mux inputs
- resolve conflicts after deleting [1]
- update commit message, previous patch [3]
- add routine find_channel_by_num to get channel by channel number
