Each SoC has two TCB blocks, each one including three independent channels.The following series adds support for two counter modes: increase and quadrature decoder. As for the atmel clocksource and pwm, the counter driver needs to fill some tcb capabilities in order to operate with the right configuration. This is achieved in first patch of this series. Please feel free to comment. Cheers, Changes in v5: - Fix duplicate keys errors in yaml dt-schema Changes in v4: - Use existing binding to document capture mode of the Microchip TCBs. Changes in v3: - Updated the brand name: s/atmel/microchip/. - Added missing kernel doc for new elements introduced in structure atmel_tcb_config. - Removed useless blank line - Added an explicit clock removing path using devm_add_action_or_reset Changes in v2: - Fixed first patch not applying on mainline - Updated return code to -EINVAL when user is requesting qdec mode on a counter device not supporting it. - Added an error case returning -EINVAL when action edge is performed in qdec mode. - Removed no need to explicity setting ops to NULL from static struct as it is the default value. - Changed confusing code by using snprintf for the sake of clarity. - Changed code to use ARRAY_SIZE so that future reviewers will know that num_counts matches what's in the atmel_tc_count array without having to check so themselves. - Fixed errors reported by dt_binding_check Alexandre Belloni (2): dt-bindings: atmel-tcb: convert bindings to json-schema dt-bindings: microchip: atmel,at91rm9200-tcb: add sama5d2 compatible Kamel Bouhara (3): ARM: at91: add atmel tcb capabilities dt-bindings: counter: microchip-tcb-capture counter counter: Add microchip TCB capture counter .../devicetree/bindings/mfd/atmel-tcb.txt | 56 --- .../soc/microchip/atmel,at91rm9200-tcb.yaml | 176 ++++++++ drivers/counter/Kconfig | 11 + drivers/counter/Makefile | 1 + drivers/counter/microchip-tcb-capture.c | 397 ++++++++++++++++++ include/soc/at91/atmel_tcb.h | 5 + 6 files changed, 590 insertions(+), 56 deletions(-) delete mode 100644 Documentation/devicetree/bindings/mfd/atmel-tcb.txt create mode 100644 Documentation/devicetree/bindings/soc/microchip/atmel,at91rm9200-tcb.yaml create mode 100644 drivers/counter/microchip-tcb-capture.c --- 2.25.0
