The devicetree property samsung,uart-fifosize must be mandatory, as the driver enquires about the FIFO sizes. This feature makes it compatible with Exynos8895's UART. Signed-off-by: Kaustabh Chakraborty --- This patch series is a part of Exynos7870 upstreaming. --- Changes in v2: - Modify UART compatible to now fallback Exynos8895 UART. - Remove the UART driver patch, no longer needed. - Link to v1: https://lore.kernel.org/r/20250204-exynos7870-uart-v1-0-06be6aa96284@disroot.org --- Documentation/devicetree/bindings/serial/samsung_uart.yaml | 4 ++++ 1 file changed, 4 insertions(+) --- base-commit: e5d3fd687aac5eceb1721fa92b9f49afcf4c3717 change-id: 20250203-exynos7870-uart-62f64cea2489 Best regards, diff --git a/Documentation/devicetree/bindings/serial/samsung_uart.yaml b/Documentation/devicetree/bindings/serial/samsung_uart.yaml index 070eba9f19d3e039090c58a82f93d02eed58ab84..83d9986d8e98a2a55615d15383c9c7fc89f5b52f 100644 --- a/Documentation/devicetree/bindings/serial/samsung_uart.yaml +++ b/Documentation/devicetree/bindings/serial/samsung_uart.yaml @@ -42,6 +42,10 @@ properties: - samsung,exynosautov9-uart - samsung,exynosautov920-uart - const: samsung,exynos850-uart + - items: + - enum: + - samsung,exynos7870-uart + - const: samsung,exynos8895-uart reg: maxItems: 1
