From: Arınç ÜNAL Date: Tue, 20 Sep 2022 17:25:50 +0000 (+0300) Subject: dt-bindings: memory: mt7621: add syscon as compatible string X-Git-Tag: v6.1-rc5~319^2~121^2~6 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=862b19b7d4a1ab3dd5a7ab95af73f8ec06fdb200;p=platform%2Fkernel%2Flinux-starfive.git dt-bindings: memory: mt7621: add syscon as compatible string The syscon string was introduced because the mt7621 clock driver needs to read some registers creating a regmap from the syscon. The bindings were added before the clock driver was properly mainlined and at first the clock driver was using ralink architecture dependent operations rt_memc_* defined in 'arch/mips/include/asm/mach-ralink/ralink_regs.h'. This string is already there on the memory controller node on mt7621.dtsi. Add syscon as a constant string on the compatible property, now that memc became a syscon. Update the example accordingly.
