2023-10-08hwmon: Annotate struct gsc_hwmon_platform_data with __counted_byKees Cook
Prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). As found with Coccinelle[1], add __counted_by for struct gsc_hwmon_platform_data.

2022-12-04hwmon: (gsc-hwmon) Switch to flexible array to simplify codeChristophe JAILLET
Using flexible array is more straight forward. It - saves 1 pointer in the 'gsc_hwmon_platform_data' structure - saves an indirection when using this array - saves some LoC and avoids some always spurious pointer arithmetic Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Link: https://lore.kernel.org/r/61a23e1d642397cfcecc4ac3bb0ab485d257987d.1668936855.git.christophe.jaillet@wanadoo.fr Signed-off-by: Guenter Roeck <linux@roeck-us.net>

2020-05-20hwmon: Add Gateworks System Controller supportTim Harvey
The Gateworks System Controller has a hwmon sub-component that exposes up to 16 ADC's, some of which are temperature sensors, others which are voltage inputs. The ADC configuration (register mapping and name) is configured via device-tree and varies board to board.
