Changes since v5: - Actually fix unit addressses for the two tsens blocks as per Stephen's comment. Changes since v4: - Revert back to a single fallback bindind qcom,tsens-v2 as per Rob's suggestion. - Rework how old (unsplit SROT and TM address space) DTs are handled by needing a 0x1000 offset but still sharing common code in tsens-v2.c - Remove the patch to added TRDY checks while we investigate Matthias' reports - Fix unit addressses for the two tsens blocks as per Stephen's comment. Changes since v3: - Introduce qcom,tsens-v2.4.0 property and make qcom,tsens-v2 a fallback, compatible property. - Rename ops_v2 to ops_generic_v2 Changes since v2: - Based on review, moved tsens-8996.c to tsens-v2.c and changed corresponding function names, struct names to allow for generic tsensv2 platforms - All v2 platforms will now only need to use the qcom,tsen-v2 property - Added a DT patch to initialize tsens driver on sdm845, now that 4.18-rc1 will contain an sdm845.dtsi Changes since v1: - Move get_temp() from tsens-8996 to tsens-common and rename - Change 8996 DT entry to allow init_common() to work across sdm845 and 8996 due to different offsets Amit Kucheria (7): thermal: tsens: Get rid of unused fields in structure thermal: tsens: Add support to split up register address space into two dt: qcom: 8996: thermal: Move to DT initialisation thermal: tsens: Rename tsens-8996 to tsens-v2 for reuse thermal: tsens: Add generic support for TSENS v2 IP dt: thermal: tsens: Document the fallback DT property for v2 of TSENS IP arm64: dts: sdm845: Add tsens nodes .../devicetree/bindings/thermal/qcom-tsens.txt | 25 +++++++++++++---- arch/arm64/boot/dts/qcom/msm8996.dtsi | 12 +++++++- arch/arm64/boot/dts/qcom/sdm845.dtsi | 16 +++++++++++ drivers/thermal/qcom/Makefile | 2 +- drivers/thermal/qcom/tsens-common.c | 11 ++++++++ drivers/thermal/qcom/{tsens-8996.c => tsens-v2.c} | 32 ++++++++++------------ drivers/thermal/qcom/tsens.c | 3 ++ drivers/thermal/qcom/tsens.h | 8 ++++-- 8 files changed, 81 insertions(+), 28 deletions(-) rename drivers/thermal/qcom/{tsens-8996.c => tsens-v2.c} (64%) Reviewed-by: Bjorn Andersson Reviewed-by: Bjorn Andersson
