Subject[PATCH v8 0/7] Netronix embedded controller driver for Kobo and Tolino ebook readers
Date
This patchset adds basic support for the embedded controller found on
older ebook reader boards designed by/with the ODM Netronix Inc.[1] and
sold by Kobo or Tolino, for example the Kobo Aura and the Tolino Shine.
These drivers are based on information contained in the vendor kernel
sources, but in order to all information in a single place, I documented
the register interface of the EC on GitHub[2].

[1]: http://www.netronixinc.com/products.aspx?ID=1
[2]: https://github.com/neuschaefer/linux/wiki/Netronix-MSP430-embedded-controller

v8:
- MFD: Add missing module metadata to the core driver
- PWM/RTC: Copy dev.of_node from the parent device, to ensure that these
devices are linked to the devicetree node

v7:
- https://lore.kernel.org/lkml/20210109180220.121511-1-j.neuschaefer@gmx.net/
- Adjust the RTC patch to a change in the RTC API:
rtc_register_device is now devm_rtc_register_device.
- Add a #define for the known firmware version (0xd726).
Lee Jones suggested doing this in a follow-up patch, but since I'm
respinning the series anyway, I'm doing it here.


Jonathan Neuschäfer (7):
dt-bindings: Add vendor prefix for Netronix, Inc.
dt-bindings: mfd: Add binding for Netronix embedded controller
mfd: Add base driver for Netronix embedded controller
pwm: ntxec: Add driver for PWM function in Netronix EC
rtc: New driver for RTC in Netronix embedded controller
MAINTAINERS: Add entry for Netronix embedded controller
ARM: dts: imx50-kobo-aura: Add Netronix embedded controller
