Subject: [PATCHv5 0/2] Fix imx53-ppd UART configuration

Hi,

IMHO PATCHv4 was better, but in the end I don't have strong feelings
about this. Btw. I think this patchset is a good demonstration of
frustrating upstream kernel development can be considering PATCHv5
is basically the same as PATCHv1. Thanks for making us go in
circles :(

Changes since PATCHv4:
 * https://lore.kernel.org/lkml/20210305115058.92284-1-sebastian.reichel@collabora.com/
 * use DT property instead of sysfs config option, like the initial patch
   version did as requested by Greg.

Changes since PATCHv3:
 * https://lore.kernel.org/lkml/1539249903-6316-1-git-send-email-fabien.lahoudere@collabora.com/
 * rewrote commit message to provide a lot more details why this is needed
 * rebased to torvalds/master (5.12-rc1-dontuse), also applies on top of linux-next
 * use sysfs_emit() instead of sprintf
