-This directory contains several versions of the Linux kernel ftdi_sio driver
-patch that adds support for FreeCalypso DUART28C adapter, i.e., the optional
-configuration of DUART28 with boot control outputs.
-
-The version in the orig-202007 directory was produced at the end of 2020-07,
-when DUART28 hardware was still being designed; this original version of the
-patch was created to test the idea and to prove it working (using a generic
-FT2232D board and an oscilloscope), and it was created with the mindset of a
-hardware engineer, rather than that of Linux kernel maintainers.  This original
-patch version was made against kernel version 4.4.14 (the version used by the
-Mother), and it predates all later mainline submission and integration attempts.
+The collection of patches to Linux kernel ftdi_sio driver (adding support for
+USB device 0403:7152 and the special quirk it requires) has moved to a new Hg
+repository of its own:
 
-A patch series against then-current mainline was submitted to ftdi_sio driver
-maintainer Johan Hovold in 2020-09 for inclusion in mainline Linux.  The
-preliminary patch adding support for FreeCalypso JTAG+UART USB ID codes was
-readily accepted and has since been propagated to several stable kernel branches
-(4.4.240, 4.9.240, 4.14.202, 4.19.152, 5.4.72, 5.8.16, 5.9.1 and mainline 5.10),
-but this patch by itself does not help in any way with DUART28C support.  The
-remaining two patches from the original 2020-09 patch series (a preliminary
-patch fixing an oversight in the quirk interface and then the main patch of
-interest) were met with resistance, however - please see the article in
-doc/Linux-DTR-RTS-flaw for the full explanation.  The short version is that
-Linux kernel maintainers are refusing to accept our patch on the basis of their
-assininity, and thus We The End Users will need to apply this patch locally on
-our own systems, probably forever, or at least for the next few billion years
-until the Sun swells into a red giant and engulfs the Earth.

-3 end user patch series versions are presented in minpatch-4.4.14,
-minpatch-4.4.240 and minpatch-4.9.240.  4.4.240 and 4.9.240 already include the
-preliminary JTAG+UART USB ID code support patch (which serves mainly as an
-anchor marking the place where the new DUART28C USB ID code needs to go in
-ftdi_sio_ids.h and in the ftdi_sio.c ID code table), but 4.4.14 predates this
-patch by a few years, thus minpatch-4.4.14 includes a backport of this
-preliminary patch as well.  After this preliminary patch, each minpatch-*
-version includes the quirk port_probe patch and the main patch adding DUART28C
-support with the needed quirk.  These latter patches are the closest version we
-ever got to a mainline-acceptable state: they already underwent rounds of
-revision in response to the maintainer's criticism, addressing and fixing
-various nitpick issues before the whole idea got shot down on more ideological
-grounds.
+The old versions contained in this directory are just that - old versions;
+the new repository contains updated versions of the patches that apply against
+newer kernels.
