regmap: Allow devices to specify regmap range start and size in config 2020-09-30T15:55:22+00:00 Pratyush Yadav p.yadav@ti.com 2020-09-24T04:34:15+00:00 d8babb9598ce237ffb1feccb576c66a21c52e5f7 Some devices need to calculate the regmap base address at runtime. This makes it impossible to use device tree to get the regmap base. Instead, allow devices to specify it in the regmap config. This will create a regmap with a single range that corresponds to the start and size given by the driver. Signed-off-by: Pratyush Yadav <p.yadav@ti.com> Reviewed-by: Simon Glass <sjg@chromium.org>

To write other lengths, regmap_raw_read() and regmap_raw_write() need to be used. This means that any driver ported from Linux that relies on regmap_{read,write}() to know the size already has to be updated at each callsite. This makes the port harder to maintain. So, allow specifying the read/write width to make it easier to port the drivers, since now the only change needed is when initializing the regmap.
