Syscon fits very well to access qfprom. This also means drivers which needs to access qfprom have to talk to syscon and get regmap, offset, size and then do regmap reads. This will be redone in every driver. Having a wrapper for this would avoid code duplication and also provide higher level and user friendly api for qfprom access. This patch attempts to provide such a wrapper. Advantages of this approch are: - driver need not hardcode qfprom offsets or have soc specific compatible strings to determine the offset. - access multiple qfprom resources which is tricky with standard syscon. - no code duplication. - light weight, single call. - not a platform device driver level binding.
