Next cycle two new SoCs will be coming (Google GS101 and ExynosAutov920), so\n they will touch the same lines in some of the DT bindings (not all, though).\n It is reasonable for me to take the bindings for the new SoCs, to have clean\n `make dtbs_check` on the new DTS.\n2. Having it together helps me to have clean `make dtbs_check` within my tree\n on the existing DTS.\n3. No drivers are affected by this change.\n4. I plan to do the same for Tesla FSD and Exynos ARM32 SoCs, thus expect\n follow up patchsets.\n\nIf folks agree, please kindly Ack the patches.\n\nDescription\n===========\nSamsung Exynos SoCs reuse several devices from older designs, thus historically\nwe kept the old (block's) compatible only. This works fine and there is no bug\nhere, however guidelines expressed in\nDocumentation/devicetree/bindings/writing-bindings.rst state that:\n1. Compatibles should be specific.\n2. We should add new compatibles in case of bugs or features.\n\nAdd compatibles specific to each SoC in front of all old-SoC-like compatibles.\nThis will also help reviews of new code using existing DTS as template. No\nfunctional impact on Linux drivers behavior.\n\nFuture\n======\nIf reasonable, I will do similar work for Tesla FSD and ARMv7/ARM32 Exynos\nbindings and DTS.\n\nBest regards,\nKrzysztof\n\nKrzysztof Kozlowski (17):\n dt-bindings: hwinfo: samsung,exynos-chipid: add specific compatibles\n for existing SoC\n dt-bindings: i2c: exynos5: add specific compatibles for existing SoC\n dt-bindings: i2c: samsung,s3c2410-i2c: add specific compatibles for\n existing SoC\n dt-bindings: mmc: samsung,exynos-dw-mshc: add specific compatibles for\n existing SoC\n dt-bindings: pinctrl: samsung: add specific compatibles for existing\n SoC\n dt-bindings: rtc: s3c-rtc: add specific compatibles for existing SoC\n dt-bindings: serial: samsung: add specific compatibles for existing\n SoC\n dt-bindings: samsung: exynos-pmu: add specific compatibles for\n existing SoC\n dt-bindings: gpu: arm,mali-midgard: add specific compatibles for\n existing Exynos SoC\n dt-bindings: iio: samsung,exynos-adc: add specific compatibles for\n existing SoC\n ASoC: dt-bindings: samsung-i2s: add specific compatibles for existing\n SoC\n dt-bindings: pwm: samsung: add specific compatibles for existing SoC\n arm64: dts: exynos5433: add specific compatibles to several blocks\n arm64: dts: exynos7: add specific compatibles to several blocks\n arm64: dts: exynos7885: add specific compatibles to several blocks\n arm64: dts: exynos850: add specific compatibles to several blocks\n arm64: dts: exynosautov9: add specific compatibles to several blocks\n\n .../bindings/gpu/arm,mali-midgard.yaml | 5 ++\n .../hwinfo/samsung,exynos-chipid.yaml | 17 +++++-\n .../devicetree/bindings/i2c/i2c-exynos5.yaml | 10 +++-\n .../bindings/i2c/samsung,s3c2410-i2c.yaml | 22 ++++---\n .../bindings/iio/adc/samsung,exynos-adc.yaml | 29 +++++----\n .../mfd/samsung,exynos5433-lpass.yaml | 2 +-\n .../bindings/mmc/samsung,exynos-dw-mshc.yaml | 25 +++++---\n .../samsung,pinctrl-wakeup-interrupt.yaml | 24 +++++---\n .../bindings/pinctrl/samsung,pinctrl.yaml | 3 +-\n .../devicetree/bindings/pwm/pwm-samsung.yaml | 2 +\n .../devicetree/bindings/rtc/s3c-rtc.yaml | 5 ++\n .../bindings/serial/samsung_uart.yaml | 14 ++++-\n .../bindings/soc/samsung/exynos-pmu.yaml | 6 ++\n .../bindings/soc/samsung/exynos-usi.yaml | 2 +-\n .../bindings/sound/samsung-i2s.yaml | 19 +++---\n arch/arm64/boot/dts/exynos/exynos5433.dtsi | 60 ++++++++++++-------\n arch/arm64/boot/dts/exynos/exynos7.dtsi | 18 +++---\n arch/arm64/boot/dts/exynos/exynos7885.dtsi | 45 +++++++++-----\n arch/arm64/boot/dts/exynos/exynos850.dtsi | 34 ++++++-----\n arch/arm64/boot/dts/exynos/exynosautov9.dtsi | 6 +-\n 20 files changed, 233 insertions(+), 115 deletions(-)" }
