regmap: add missing dependency on SoundWire

2020-07-08T14:27:28Z

CONFIG_REGMAP is not selected when no other serial bus is supported. It's largely academic since CONFIG_I2C is usually selected e.g. by DRM, but still this can break randconfig so let's be explicit.

soundwire: fix regmap dependencies and align with other serial links

2019-08-09T04:50:40Z

The existing code has a mixed select/depend usage which makes no sense. config SOUNDWIRE_BUS tristate select REGMAP_SOUNDWIRE config REGMAP_SOUNDWIRE tristate depends on SOUNDWIRE_BUS Let's remove one layer of Kconfig definitions and align with the solutions used by all other serial links.

regmap: add i3c bus support

Add basic support for i3c bus. This is a simple implementation that only give support for SDR Read and Write commands. Signed-off-by: Vitor Soares 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.

Pull char/misc driver updates from Greg KH: "Here is the big pull request for char/misc drivers for 4.16-rc1. There's a lot of stuff in here. Three new driver subsystems were added for various types of hardware busses: - siox - slimbus - soundwire as well as a new vboxguest subsystem for the VirtualBox hypervisor drivers. There's also big updates from the FPGA subsystem, lots of Android binder fixes, the usual handful of hyper-v updates, and lots of other smaller driver updates.

regmap: add SLIMbus support

2017-12-19T10:01:03Z

This patch adds support to read/write SLIMbus value elements. Currently it only supports byte read/write. Adding this support in regmap would give codec drivers more flexibility when there are more than 2 control interfaces like SLIMbus, i2c. Without this patch each codec driver has to directly call SLIMbus value element apis, and this could would get messy once we want to add i2c interface to it.
