this series
- adds a new USB ethernet driver for adapters that are based on the
MCS7730/7830/7832 chips
- enables the driver for those boards which previously had support for
"all other" USB ethernet adapters
- updates the README.usb documentation file to list all available
drivers for USB ethernet adapters
development was done on a taskit stamp9g20, tests were done on the
taskit stamp9g20 as well as wandboard both with "Delock 61147" and
"Logilink UA0025C" adapters, transferring a 56MB file several times
with TFTP
there are several checkpatch warnings
- about CamelCase for NetReceive() and USB related structure members,
which cannot get fixed as the names are in the established API
- about a multiple assignment for the "found" flags in the USB endpoint
search, which I consider acceptable
Changes in v4:
- remove a duplicate comment in the mcs7830_read_phy() routine
- remove the actually unused mcs7830_read_config() routine
Changes in v3:
- pick up Simon's ACKs for individual patches
- drop the part of the series which moves BIT() to <common.h>
- remove BIT() macro use, declare constant numbers for bit masks
for improved portability
- re-word the commit message, include a link to the www.asix.com.tw
product page, and explictly list the supported chips
Changes in v2:
- introduced the "no #ifdef for prototypes" patch
- don't #ifdef function prototypes in header files (the newly introduced
mcs7830_*() routines in usb_ether.h)
- remove editor navigation pseudo comments (text fold markers)
- reduce the number of timeout declarations (only USB communication and
ethernet link status remaining)
- declare the ethernet adapter register set layout by means of a struct
and offsetof() instead of magic register index numbers
- separate the bit mask declarations from the register layout
declaration, use the common BIT() macro instead of re-inventing its
implementation
- rename register layout and bit field macros to reduce excessive
identifier lengths, and to not collide with the global CONFIG_* name
space
- introduce kernel nano doc comments for data structures, global
variables, and all routines
- improve handling of the list of supported dongles, remove the unused
sentinel and iterate by means of ARRAY_SIZE(), fixup whitespace for
the Sitecom entry
- decorate the mcs7830_read_config() routine with the "__maybe_unused"
attribute instead of forcing a reference by means of
"(void)identifier;" just to silence a potential compiler warning
- silent operation of the ethernet link status detection according to
U-Boot philosophy, which simplifies the .init() callback code path
- factor out common logic of PHY read/write support (the "emit a request
and wait for completion" part), unbreak the retry logic (correct
number of iterations)
- use proper errno.h codes, and propagate errors up in the call chain
- adjust the Cc: list
- introduce the patch to alpha-sort USB adapter config options
- introduce the patch to add MCS7830 USB ethernet to several boards
- introduce the patch to add MCS7830 USB ethernet for taskit stamp9g20
- introduce the patch to update README.usb for USB ethernet options
