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.

After finding a reasonable gain, the function converts the configured gain to a gain configuration option selector enum max9611_csa_gain. Make the conversion clearly visible by using an explicit cast. This also avoids a warning seen with clang: drivers/iio/adc/max9611.c:292:16: warning: implicit conversion from enumeration type 'enum max9611_conf_ids' to different enumeration type 'enum max9611_csa_gain' [-Wenum-conversion] *csa_gain = gain_selectors[i]; ~ ^~~~~~~~~~~~~~~~~ Signed-off-by:Stefan Agner <stefan@agner.ch> Signed-off-by:

In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through.

Compatible strings tend to follow manufacturer,model format. In case one wants to do a matching with manufacturer stripped off he can still do so since SPI/I2C core will try id_table based matching anyway. Signed-off-by:

This patch adds support for QCOM SPMI PMIC5 family of ADC driver that supports hardware based offset and gain compensation. The ADC peripheral can measure both voltage and current channels whose input signal is connected to the PMIC ADC AMUX. The register set and configuration has been refreshed compared to the prior QCOM PMIC ADC family. Register ADC5 as part of the IIO framework. Signed-off-by:

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:

I have disabed CONFIG_EROFS_FS for now:" The reason of compiling error is: Since -next collects and merges developing patches including common vfs stuff from multi-trees, but those patches didn't cover erofs, such as: ('vfs: Suppress MS_* flag defs within the kernel unless explicitly enabled") https://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git/commit/?h=for-next&id=109b45090d7d3ce2797bb1ef7f70eead5bfe0ff3 ("vfs: Require specification of size of mount data for internal mounts") https://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git/commit/?h=for-next&id=0a191e4505a4f255e6513b49426213da69bf0e80 Above vfs related patches has not been merged in staging tree, if we submit those erofs patches to staging mailing list and after including them in staging-{test,nexts} tree, it can easily cause compiling error. We worked out some patches to adjust those vfs change, but now we just submit them to -next tree temporarily to avoid compiling error. For potentail conflict in between erofs and vfs changes in incoming merge window, Stephen suggested that we can disable CONFIG_EROFS_FS temporarily to pass merge window, and after that we can do restore by reenabling CONFIG_EROFS_FS and applying those fixing patches. Also Greg confirmed this solution. So, let's disable compiling erofs for a while. Suggested-by:Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by:

Apex doesn't implement different types of resets based on the reset type param passed through the gasket layer or from userspace via the gasket_reset ioctl. The reset type is dropped from the gasket framework in a previous patch due to a lack of present need and non-conforming use of this parameter by the framework. Drop the parameter from the apex driver as well. Signed-off-by:

Todd Poynor authored
The "type of reset" parameter to the gasket device reset APIs isn't required by the only gasket device submitted upstream, apex. The framework documents the param as private to the device driver and a pass-through at the gasket layer, but the gasket core calls the device driver with a hardcoded reset type of zero, which is not documented as having a predefined meaning. In light of all this, remove the reset type parameter from the framework. Remove the reset ioctl reset type parameter, and bump the framework version number to reflect the interface change.
