From e9cde87ec1eaba3b5233093aec8f4f6c256b3a54 Mon Sep 17 00:00:00 2001 From: Heiko Schocher Date: Tue, 16 Apr 2019 13:31:58 +0200 Subject: dtb_platdata.py: prevent define generation of alias generate define for an alias only if the struct is not created already. This prevents compilerwarning: PLAT spl/dts/dt-platdata.o spl/dts/dt-platdata.c:11:46: error: missing braces around initializer [-Werror=missing-braces] static const struct dtd_simple_bus dtv_ahb = { ^ spl/dts/dt-platdata.c:20:46: error: missing braces around initializer [-Werror=missing-braces] static const struct dtd_simple_bus dtv_apb = { ^ cc1: all warnings being treated as errors on the at91 based taurus board. Reason is in at91sam9260.dtsi is defined: ahb { compatible = "simple-bus"; ranges; and later: pinctrl: pinctrl@fffff400 { compatible = "atmel,at91rm9200-pinctrl", "simple-bus"; ranges = <0xfffff400 0xfffff400 0x600>; without this patch dtoc generates: struct dtd_atmel_at91rm9200_pinctrl { fdt32_t atmel_mux_mask[6]; fdt32_t ranges[3]; fdt32_t reg[6]; }; struct dtd_simple_bus { bool ranges; }; "#define dtd_simple_bus dtd_atmel_at91rm9200_pinctrl" and the line with "define dtd_simple_bus..." introduces the warning. This define is not needed.
