Could copy me the mfd.c file of da9063 in the lkml?

Subject: DA9063 driver development

Hello,

I am late into the discussion about the DA9063 driver because I missed the e-mail thread around 24th July
(https://lkml.org/lkml/2013/7/24/460)
so I only recently noticed that a DA9063 driver from Philipp Zabel had been submitted and accepted to linux-next.

I also noted that this driver was using a previous patch-set as its baseline; sent by Krystian Garbaciak over a year ago. Given that this original patch-set was not accepted, and the production of the DA9063 chip has advanced since the last submission, we were holding off the final DA9063 driver until later.

As I discussed earlier in https://lkml.org/lkml/2013/6/28/170 I was in the process of getting this driver ready for submission to the kernel.

It is well understood that any early submission of our driver to the community (around v3.6) meant that this sort of external driver development could happen without any further input from Dialog. However, this driver:

- is based on something that is a year old and now out of date;
- it cannot support the most recent mass-production release of DA9063 silicon;

Is it possible to remove this driver from linux-next so these issues can be resolved by Dialog?

Regards,
Steve Twiss
