There is also a rework of the 32khz clock handling so it is not used for clockevents on 32 bit counter because the increased rate improves the resolution and doesn't have any drawback with that counter width. This replaces a patch that has been carried in the linux-rt tree for a while. Changes in v3: - Moved the child node documentation to the parent documentation Changes in v2: - Rebased on v5.7-rc1 - Moved the binding documentation to its proper place - Added back the atmel,tcb-timer child node documentation Alexandre Belloni (8): dt-bindings: atmel-tcb: convert bindings to json-schema dt-bindings: microchip: atmel,at91rm9200-tcb: add sama5d2 compatible ARM: dts: at91: sama5d2: add TCB GCLK clocksource/drivers/timer-atmel-tcb: rework 32khz clock selection clocksource/drivers/timer-atmel-tcb: fill tcb_config clocksource/drivers/timer-atmel-tcb: stop using the 32kHz for clockevents clocksource/drivers/timer-atmel-tcb: allow selecting first divider clocksource/drivers/timer-atmel-tcb: add sama5d2 support Kamel Bouhara (1): ARM: at91: add atmel tcb capabilities .../devicetree/bindings/mfd/atmel-tcb.txt | 56 ------- .../soc/microchip/atmel,at91rm9200-tcb.yaml | 150 ++++++++++++++++++ arch/arm/boot/dts/sama5d2.dtsi | 12 +- drivers/clocksource/timer-atmel-tcb.c | 101 +++++++----- include/soc/at91/atmel_tcb.h | 5 + 5 files changed, 219 insertions(+), 105 deletions(-) delete mode 100644 Documentation/devicetree/bindings/mfd/atmel-tcb.txt create mode 100644 Documentation/devicetree/bindings/soc/microchip/atmel,at91rm9200-tcb.yaml
