TSENS IP v2.x supports critical interrupts and v2.3+ adds watchdog support in case the FSM is stuck. Enable support in the driver. This series was generated on top of v5.6-rc2. Changes since v6: - Fix up some lines over 80 characters - Remove Link tags Changes since v5:¬ - Introduce a function tsens_register_irq to handle uplow and critical interrupt registration and reduce code duplication - Clarify reason for patch 04 Changes from v4: - Add back patch 1 from v3[*], I mistakenly didn't post it for v4. - Remove spinlock from critical interrupt handling - Change critical interrupt handler to fall thru watchdog bark handling to handle critical interrupts too [*] https://lore.kernel.org/linux-arm-msm/77dd80eb58f0db29a03097cb442d606f810a849a.1577976221.git.amit.kucheria@xxxxxxxxxx/ Changes from v3: - Remove the DTS changes that are already queued - Fix review comments by Bjorn - Fixup patch description to clarify that we don't use TSENS critical interrupts in Linux, but need it for the watchdog support that uses the same HW irq line. - Separate kernel-doc fixes into a separate patch. Changes from v2: - Handle old DTBs w/o critical irq in the same way as fix sent for 5.5 Changes from v1: - Make tsens_features non-const to allow run time detection of features - Pass tsens_sensor around as a const - Fix a bug to release dev pointer in success path - Address review comments from Bjorn and Stephen (thanks for the review) - Add msm8998 and msm8996 DTSI changes for critical interrupts Amit Kucheria (8): drivers: thermal: tsens: De-constify struct tsens_features drivers: thermal: tsens: Pass around struct tsens_sensor as a constant drivers: thermal: tsens: use simpler variables drivers: thermal: tsens: Release device in success path drivers: thermal: tsens: Add critical interrupt support drivers: thermal: tsens: Add watchdog support drivers: thermal: tsens: kernel-doc fixup drivers: thermal: tsens: Remove unnecessary irq flag drivers/thermal/qcom/tsens-8960.c | 4 +- drivers/thermal/qcom/tsens-common.c | 194 ++++++++++++++++++++++++---- drivers/thermal/qcom/tsens-v0_1.c | 6 +- drivers/thermal/qcom/tsens-v1.c | 6 +- drivers/thermal/qcom/tsens-v2.c | 24 +++- drivers/thermal/qcom/tsens.c | 65 ++++++---- drivers/thermal/qcom/tsens.h | 103 +++++++++++++-- 7 files changed, 331 insertions(+), 71 deletions(-) -- 2.20.1
