This patch depends on patch series [1] and [2]. [1]: Initial device tree support for StarFive JH8100 SoC https://lore.kernel.org/all/20231201121410.95298-7-jeeheng.sia@starfivetech.com/ [2]: Basic clock and reset support for StarFive JH8100 RISC-V SoC https://lore.kernel.org/all/20231206115000.295825-17-jeeheng.sia@starfivetech.com/ Changes since v3: - Drop items in compatible field. - Replace items with maxItems in reset field. - Replace maxItems with items: -description in if else reset field Changes since v2: - Express JH8100 compatibility to JH7110 in dt-bindings. - Rework min/maxItems constraint for JH8100 resets property. Changes since v1: - Drop "starfive,jh8100-wdt" compatible field in starfive-wdt.c, and express them in dt-bindings. - Use minItems in resets field to cater for single reset signal in JH8100. - Reword Watchdog reset to Core reset for JH8100. StarFive's JH8100 watchdog reuses JH7100 register mapping. DT-binding of JH7100 watchdog is extended to support JH8100. Since JH8100 only uses 1 reset signal, update the binding to support one reset for "starfive,jh8100-wdt" compatible.
