I originally made this patch on top of:
800e3b9a6801 Input: drop owner assignment from i2c_driver
Hi,
While testing a gas gauge, we encountered intermittent i2c issues with
the APQ8016. Sometimes, the i2c controller seems to send incomplete
messages, or doesn't send some messages. To read values from the gas
gauge, this group of two messages is sent:
- one write message of 1 byte, with the g
Drop assignments to bias-disable as the documentation [1] states that
this property doesn't take a value. Other occurrences of this property
respect that.

Hi,
I'm working on a board derived from the DragonBoard-410c (apq8016 +
wcn3620) and noticed an issue with WiFi connection monitoring. When I
get out of the range of the access point, the device stays associated,
no matter how far I go or how long I wait.
The chip on this board is the WCN3620, a

The previous version of this patch luckily worked with the clk_div_table

This commit adds the capability to allocate and init private data
embedded in the sja1000_priv structure on a per-compatible basis. The
device node is passed as a parameter of the init callback to allow
parsing of custom device tree properties.

On this board, the touchscreen, an ads7843, is not handled directly by
Linux but by a companion FPGA. This FPGA is memory-mapped and the IP
design is very similar to the mk712.
This commit adds the support for this IP.
