2023-02-22mfd: ntxec: Add version number for EC in Tolino VisionAndreas Kemnade
The EC firmware has a different version number than anything defined until now. Signed-off-by: Andreas Kemnade <andreas@kemnade.info> Signed-off-by: Lee Jones <lee@kernel.org> Link: https://lore.kernel.org/r/20230127165828.3256170-1-andreas@kemnade.info
2021-12-29mfd: ntxec: Change return type of ntxec_reg8 from __be16 to u16Jonathan Neuschäfer
Register values in NTXEC are big-endian on the I2C bus, but the regmap subsystem handles the conversion between CPU-endian and big-endian data internally. ntxec_reg8 should thus return u16, not __be16.

2021-04-14mfd: ntxec: Support for EC in Tolino Shine 2 HDAndreas Kemnade
Add the version of the EC in the Tolino Shine 2 HD to the supported versions. It seems not to have an RTC and does not ack data written to it. The vendor kernel happily ignores write errors, using I2C via userspace i2c-set also shows the error. So add a quirk to ignore that error. PWM can be successfully configured despite of that error.

2021-03-10mfd: Add base driver for Netronix embedded controllerJonathan Neuschäfer
The Netronix embedded controller is a microcontroller found in some e-book readers designed by the original design manufacturer Netronix, Inc. It contains RTC, battery monitoring, system power management, and PWM functionality. This driver implements register access and version detection. Third-party hardware documentation is available at: https://github.com/neuschaefer/linux/wiki/Netronix-MSP430-embedded-controller The EC supports interrupts, but the driver doesn't make use of them so far.
