This is a small patchset about tuning the syscon infrastructure a bit. As it's going to be general in the framework of the Baikal-T1 SoC support integration into the kernel, we suggest to replace the legacy text-based syscon-reboot-mode dts-bindings file with yaml-based one. Then seeing a syscon reboot block is normally expected to be a part of a system controller and based on the discussion https://lore.kernel.org/linux-pm/20200306130402.1F4F0803079F@xxxxxxxxxxxxxxxxxxxxxxxxx/ we decided to alter the syscon reboot driver so one would also try to fetch the syscon registers map from a parental DT node. regmap property is left supported although it's marked as deprecated from now. This patchset is rebased and tested on the mainline Linux kernel 5.7-rc4: 0e698dfa2822 ("Linux 5.7-rc4") tag: v5.7-rc4 Changelog v2: - Add Sebastian' Acked-by tag to patch 1. - Use a shorter summary describing the bindings modification patches. - Our corporate email server doesn't change Message-Id anymore, so the patchset is resubmitted being in the cover-letter-threaded format. - Discard patch with syscon "-endian" property support. As Rob said It shall be in the common dt-schema. - Replace patches of adding a regmap property support to the syscon-reboot-mode with patches making syscon-reboot a sub-node of a system controller node. - Mark regmap property as deprecated from now.
