SubjectRe: [PATCH v5 0/5] Genericize DW MIPI DSI bridge and add i.MX 6 driver
From

Hi Adrian,

Due to different ways of work I use different mail client, so forgive me
if there are some misconfugrations.

So we have above 400 lines more just to add slightly different register
layout of v1.01.

Quite big linecount for apparently small (?) functional change - I was
too lazy to check how many reg fields are really used (some are not used
at all), but it does not seem to be big enough to justyfy so big change IMO.

I will add more comments in specific patches.


Regards

Andrzej
