This driver is intended to be used by other devices as well, which require just a simple MMIO access to read temperature. Changes since v2: ================= - dt-binding: changed node name from "thermal_z0" to "thermal-z0" - dt-binding: changed node name from thermalz0_crit to "critical" Changes since v1: ================== - removed the "thermal_mmio" compatible string. With v2 version, only specific hardware can bound - add initialization function that is mapped based on the specific binding string - removed thermal_mmio_readl and thermal_readw, but kept mmio reads in callback function. Left only thermal_mmio_reab which is used by al-thermal - removed divider, bias, width which are not needed for al-thermal.
