Fix that by introducing separate maps for lookups properties in both directions. The other approach that I tried is manual shifting properties: + if (battmgr->variant == QCOM_BATTMGR_TAOYAO && prop > BATT_CHG_CTRL_LIM_MAX) + prop++; ... + if (battmgr->variant == QCOM_BATTMGR_TAOYAO && property > BATT_CHG_CTRL_LIM_MAX + 1) + property--; But I found that more obscure. Will be happy to switch if the maintainers prefer this one. Changes in v4: - Added Konrad's r-b (patch #2) - Dropped RFC tag Changes in v3: - Fix QCOM_BATTMGR_TAOYAO enum ordering (patch #2) - Order in qcom_battmgr_of_variants[] is already right (no change) - Revert the qcom,sm7325-pmic-glink SoC fallback (patch #1 and #3) - Rephrased commit message (patch #3) - Design question from v1/v2 still open: lookup tables vs. inline shift Changes in v2: - Keep the qcom,sm7325-pmic-glink SoC fallback in the compatible chain of the taoyao pmic-glink node (review feedback, patch #1 and #3) Stanislav Zaikin (3): dt-bindings: soc: qcom: add xiaomi,taoyao-pmic-glink compatible power: supply: qcom_battmgr: add Xiaomi taoyao support arm64: dts: qcom: sm7325-xiaomi-taoyao: switch to device-specific pmic-glink compatible .../bindings/soc/qcom/qcom,pmic-glink.yaml | 1 + .../boot/dts/qcom/sm7325-xiaomi-taoyao.dts | 2 +- drivers/power/supply/qcom_battmgr.c | 86 ++++++++++++++++++- 3 files changed, 84 insertions(+), 5 deletions(-) -- 2.53.0
