PM8150{,b,l} and sm8250-mtp board device trees are extended to support thermal zones provided by this thermal monitoring block. Unlike the rest of PMIC thermal senses, these thermal zones describe particular thermistors, which differ between from board to board. Changes since v8: - Simplified qcom_vadc_map_voltage_temp() code by removing ascending tables support - Simplified qcom-vadc-common volt/temp mapping code - Implement suggestions by Matthias Kaehlcke: message formatting, rewrite comments, remove unused variable initialization. Changes since v7: - Move qcom-vadc-common.h header to include/linux/iio/adc/ dir. - Use explicit sizeof(var) instead of hand-coding 1 when accessing adc-tm registers. - Remove buffer read from adc_tm5_init(). - Remove extra on-stack var from adc_tm5_get_temp(). - Minor formatting changes as suggested Daniel. Changes since v6: - Added include as noted by Jishnu Prakash. Changes since v5: - Reworked DT bindings: * Removed qcom,adc-channel, instead it is parsed from io-channels * Renamed qcom,hw-settle-time to include -us suffix - Re-added monitor enabling which got lost during refactored. Noted by Jishnu Prakash. - Use threaded IRQ handler as susggested by Jishnu. Changes since v4: - Added kernel-doc comments to ADC-TM structures - Used several sizeof(buf) instead of hand-conding register size Changes since v3: - Fix DT description to spell "thermal monitoring" instead of just TM - Fix warnings in DT example - Add EXPORT_SYMBOL_GPL(of_iio_channel_get_by_name) - Fixed whitespace chanes in qcom-vadc-common.c - Removed error message if IIO chanel get returns -EPROBE_DEFER Changes since v2: - IIO: export of_iio_channel_get_by_name() function - dt-bindings: move individual io-channels to each thermal monitoring channel rather than listing them all in device node - added fallback defaults to of_device_get_match_data calls in qcom-spmi-adc5 and qcom-spmi-adc-tm5 drivers - minor typo fixes Changes since v1: - Introduce fixp_linear_interpolate() by Craig Tatlor - Lots of syntax/whitespace changes - Cleaned up register definitions per Jonathan's suggestion - Implemented most of the suggestions from Bjorn's and Jonathan's review
