regmap: Support non-incrementing registers Some devices have individual registers that don't autoincrement the register address during bulk reads but instead repeatedly read the same value, for example for monitoring GPIOs or ADCs. Add support for these.

regmap: Add regmap_noinc_read API

2018-08-09T10:00:15Z

The regmap API usually assumes that bulk read operations will read a range of registers but some I2C/SPI devices have certain registers for which a such a read operation will return data from an internal FIFO instead. Add an explicit API to support bulk read without range semantics. Some linux drivers use regmap_bulk_read or regmap_raw_read for such registers, for example mpu6050 or bmi150 from IIO. This only happens to work because when caching is disabled a single regmap read op will map to a single bus read op (as desired). This breaks if caching is enabled and reg+1 happens to be a cacheable register. Without regmap support refactoring a driver to enable regmap caching requires separate I2C and SPI paths. This is exactly what regmap is supposed to help avoid. Suggested-by: Jonathan Cameron Signed-off-by: Crestez Dan Leonard Signed-off-by: Stefan Popa Signed-off-by: Mark Brown

regmap: add SCCB support

2018-07-18T14:45:23Z

This adds Serial Camera Control Bus (SCCB) support for regmap API that is intended to be used by some of Omnivision sensor drivers. The ov772x and ov9650 drivers are going to use this SCCB regmap API. The ov772x driver was previously only worked with the i2c controller drivers that support I2C_FUNC_PROTOCOL_MANGLING, because the ov772x device doesn't support repeated starts. After commit 0b964d183cbf ("media: ov772x: allow i2c controllers without I2C_FUNC_PROTOCOL_MANGLING"), reading ov772x register is replaced with issuing two separated i2c messages in order to avoid repeated start. Using this SCCB regmap hides the implementation detail. The ov9650 driver also issues two separated i2c messages to read the registers as the device doesn't support repeated start. So it can make use of this SCCB regmap.

regmap: slimbus: add support to multi read/write

2018-07-11T10:58:04Z

SLIMbus supports upto 16 bytes in value management messages, so add support to read/writes upto 16 bytes. This also removes redundant single register reg_read/reg_write. Also useful for paged register access on SLIMbus interfaced codecs. Signed-off-by: Srinivas Kandagatla Signed-off-by: Mark Brown

regmap: Skip clk_put for attached clocks when freeing context

2018-05-17T07:11:41Z

Capability to attach an existing clk to a MMIO regmap was introduced in 4.17rc1. However, when using attached clk, regmap does not do the clk_get. Therefore it should not do the clk_put when freeing the MMIO regmap context. There does not appear to be any users of attached clocks yet so this would be a good time to make this change before anything depends on the existing behaviour.
