This patch series adds initial platform support for Samsung Exynos850 SoC [1]. With this patchset it's possible to run the kernel with BusyBox rootfs as a RAM disk. More advanced platform support (like MMC driver additions) will be added later. The idea is to keep the first submission minimal to ease the review, and then build up on top of that. [1] https://www.samsung.com/semiconductor/minisite/exynos/products/mobileprocessor/exynos-850/ Changes in v3: * Removed the stub clock driver; uart clock is modeled as generic fixed clock in dts for now * See also changes in each particular patch Changes in v2: * Rebased on top of current linux-mainline * Removed patch ("pinctrl: samsung: Fix pinctrl bank pin count"); it was sent separately, as it's an independent fix * Made the patch ("dt-bindings: pinctrl: samsung: Add Exynos850 doc") to be the first in series * Removed patch ("MAINTAINERS: Changes in v2"); will add that later, when proper clock driver is implemented * Removed patch ("dt-bindings: clock: Add bindings for Exynos850 clock controller"); will add clock bindings later, when proper clock driver is implemented * Removed patch ("dt-bindings: interrupt-controller: Add IRQ constants for Exynos850"), and used hard-coded IRQ numbers in dts instead * See also changes in each particular patch Sam Protsenko (7): dt-bindings: pinctrl: samsung: Add Exynos850 doc pinctrl: samsung: Add Exynos850 SoC specific data dt-bindings: serial: samsung: Add Exynos850 doc tty: serial: samsung: Init USI to keep clocks running tty: serial: samsung: Fix driver data macros style tty: serial: samsung: Add Exynos850 SoC data arm64: dts: exynos: Add Exynos850 SoC support .../bindings/pinctrl/samsung-pinctrl.txt | 1 + .../bindings/serial/samsung_uart.yaml | 1 + .../boot/dts/exynos/exynos850-pinctrl.dtsi | 748 ++++++++++++++++++ arch/arm64/boot/dts/exynos/exynos850.dtsi | 261 ++++++ .../pinctrl/samsung/pinctrl-exynos-arm64.c | 116 +++ drivers/pinctrl/samsung/pinctrl-exynos.h | 29 + drivers/pinctrl/samsung/pinctrl-samsung.c | 2 + drivers/pinctrl/samsung/pinctrl-samsung.h | 1 + drivers/tty/serial/samsung_tty.c | 49 +- include/linux/serial_s3c.h | 9 + 10 files changed, 1214 insertions(+), 3 deletions(-) create mode 100644 arch/arm64/boot/dts/exynos/exynos850-pinctrl.dtsi create mode 100644 arch/arm64/boot/dts/exynos/exynos850.dtsi
