They might be required by board dts files and it's convenient to use them but I don't think they should be pre-defined. We can override the sd2_clk_pins like below in a board dts file. &sd2_clk_pins { samsung,pin-drv = <EXYNOS850_HSI_PIN_DRV_LV4>; Otherwise, looks good to me.

The patch is not that big and splitting it into several addons does not bring benefits. You still add new DTSI - either in one or two patches, there is going to be the same amount of code to review. One still has to review everything. It would be different if DTSI was already applied - then incremental updates make sense. Another reason for splitting is for different topics, when doing multiple separate actions, like fix + add, change + add. Best regards, Krzysztof

Samsung Exynos850 is ARMv8-based mobile-oriented SoC. This patch adds initial SoC support. It's not comprehensive yet, some more devices will be added later. Right now only crucial system components and most needed platform devices are defined. Crucial features (needed to boot Linux up to shell with serial console): * Octa cores (Cortex-A55), supporting PSCI v1.0 * ARM architected timer (armv8-timer) * Interrupt controller (GIC-400) * Pinctrl nodes for GPIO * Serial node Basic platform features: * Clock controller CMUs * OSCCLK clock * RTC clock * MCT timer * ARM PMU (Performance Monitor Unit) * Chip-id * RTC * Reset * Watchdog timers * eMMC * I2C * HSI2C * USI All those features were already enabled and tested on E850-96 board with minimal BusyBox rootfs.
