Subject: [PATCH v5 0/5] Add support for LTC6373
The LTC6373 is a silicon, 3-bit Fully-Differential digital instrumentation
amplifier that supports the following programmable gains (Vout/Vin):
G = 0.25, 0.5, 1, 2, 4, 8, 16 + Shutdown.
The programmable interface consists of 3 digitally controled inputs.
V4->V5
Move converion logic:
- Modify to use callbacks
Use pointers in match table:
- Drop enum type from state
Driver:
- Use DIV_ROUND_CLOSEST for conversion
- Remove comma from ltc6373_ext_info[]
V3->V4
- Fix git commit message typo and remove newline between tags
V2->V3
- Use return instead of break in *_gain_dB_to_code()
- Add new line before return in *_code_to_gain_dB()
- Match parameter alignment for added _powerdown functions
- Add precursor patch for using pointers in the match table
- Add chip_info attributes: has_powerdown and powerdown_val
- Change probe logic to use has_powerdown for default powerdown state
- Added 'Fixes' tag to commit message of 'add conditional GPIO array...'
V1->V2
Driver:
- Fix chip info table indent
- Remove enable attribute
- Add ext_info powerdown attribute
- Enable by default powerdown attribute
- Set default gain after disabling powerdown to min value
Binding:
- Fix conditional checking of GPIO array size for LTC6373
- Add precursor commit for correctly checking gpio size depending upon compatible
Dumitru Ceclan (5):
