This is a simple implementation which only implements register accesses via the Extended Register Read/Write Long commands.

A simple demonstration implementation is included that just splits the block write request into a sequence of single register writes. The implementation will be modified later to support those I2C clients that implement the alternative non-standard MULTIWRITE block write mode so to achieve a single I2C transfer that will be atomic even in multiple I2C master systems.

The update bits operations are only likely to be effective when used with devices that have caches but this is common enough to be useful.

This is useful when initialising the register ranges of the device like static const struct regmap_range readable_ranges[] = { regmap_reg_range(DEVICE_REG0, DEVICE_REG10), }; Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com> Signed-off-by: Mark Brown <broonie@linaro.org> 2013-09-17T12:46:57+00:00 Kuninori Morimoto kuninori.morimoto.gx@renesas.com 2013-09-02T03:30:50+00:00 urn:sha1:a0102375ee82db1e08324b1a21484854cf2c1677 Current Linux kernel is supporting regmap_field method and it is very useful feature. It needs one regmap_filed for one register access. OTOH, there is multi port device which has many same registers in the market. The difference for each register access is only its address offset. Current API needs many regmap_field for such device, but it is not good. This patch adds new regmap_fileds API which can care about multi port/offset access via regmap.
