[LEDE-DEV] [PATCH v2 4/6] kernel: mac80211: add pending ath9k EEPROM swapping patches

There are two types of swapping the EEPROM data in the ath9k driver.
Before this series one type of swapping could not be used without the
other.
The first type of swapping looks at the "magic bytes" at the start of
the EEPROM data and performs swab16 on the EEPROM contents if needed.
The second type of swapping is EEPROM format specific and swaps
specific fields within the EEPROM itself (swab16, swab32 - depends on
the EEPROM format).
With this series the second part now looks at the EEPMISC register
inside the EEPROM, which uses a bit to indicate if the EEPROM data
is Big Endian (this is also done by the FreeBSD kernel).
This has a nice advantage: currently there are some out-of-tree hacks
(in OpenWrt and LEDE) where the EEPROM has a Big Endian header on a
Big Endian system (= no swab16 is performed) but the EEPROM itself
indicates that it's data is Little Endian. Until now the out-of-tree
code simply did a swab16 before passing the data to ath9k, so ath9k
first did the swab16 - this also enabled the format specific swapping.
These out-of-tree hacks are still working with the new logic, but it
is recommended to remove them. This implementation is based on a
discussion with Arnd Bergmann who raised concerns about the
robustness and portability of the swapping logic in the original OF
support patch review, see [0].
After a second round of patches (= v1 of this series) neither Arnd
Bergmann nor I were really happy with the complexity of the EEPROM
swapping logic. Based on a discussion (see [1] and [2]) we decided
that ath9k should use a defined format (specifying the endianness
of the data - I went with __le16 and __le32) when accessing the
EEPROM fields. A benefit of this is that we enable the EEPMISC based
swapping logic by default, just like the FreeBSD driver, see [3]. On
the devices which I have tested (see below) ath9k now works without
having to specify the "endian_check" field in ath9k_platform_data (or
a similar logic which could provide this via devicetree) as ath9k now
detects the endianness automatically. Only EEPROMs which are mangled
by some out-of-tree code still need the endian_check flag (or one can
simply remove that mangling from the out-of-tree code).

+Subject: [v2 PATCH 1/7] ath9k: Add a #define for the EEPROM "eepmisc" endianness
+ bit
+
+This replaces a magic number with a named #define. Additionally it
+removes two "eeprom format" specific #defines for the "big endianness"
+bit which are the same on all eeprom formats.

+Subject: [v2 PATCH 2/7] ath9k: indicate that the AR9003 EEPROM template values
+ are little endian
+
+The eepMisc field was not set explicitly. The default value of 0 means
+that the values in the EEPROM (template) should be interpreted as little
+endian. However, this is not clear until comparing the AR9003 code with
+the other EEPROM formats.
+To make the code easier to understand we explicitly state that the values
+are little endian - there are no functional changes with this patch.

+Subject: [v2 PATCH 4/7] ath9k: replace eeprom_param EEP_MINOR_REV with
+ get_eeprom_rev
+
+get_eeprom(ah, EEP_MINOR_REV) and get_eeprom_rev(ah) are both doing the
+same thing: returning the EEPROM revision (12 lowest bits). Make the
+code consistent by using get_eeprom_rev(ah) everywhere.

+Subject: [v2 PATCH 5/7] ath9k: consistently use get_eeprom_rev(ah)
+
+The AR5416_VER_MASK macro does the same as get_eeprom_rev, except that
+one has to know the actual EEPROM type (and providing a reference to
+that in a variable named "eep"). Additionally the eeprom_*.c
+implementations used the same shifting logic multiple times to get the
+eeprom revision which was also unnecessary duplication of
+get_eeprom_rev.
+
+Also use the AR5416_EEP_VER_MINOR_MASK macro where needed and introduce
+a similar macro (AR5416_EEP_VER_MAJOR_MASK) for the major version.
+Finally drop AR9287_EEP_VER_MINOR_MASK since it simply duplicates the
+already defined AR5416_EEP_VER_MINOR_MASK.

+Subject: [v2 PATCH 6/7] ath9k: Make the EEPROM swapping check use the eepmisc
+ register
+
+There are two ways of swapping the EEPROM data in the ath9k driver:
+1) swab16 based on the first two EEPROM "magic" bytes (same for all
+ EEPROM formats)
+2) field and EEPROM format specific swab16/swab32 (different for
+ eeprom_def, eeprom_4k and eeprom_9287)
+
+The result of the first check was used to also enable the second swap.
+This behavior seems incorrect, since the data may only be byte-swapped
+(afterwards the data could be in the correct endianness).
+Thus we introduce a separate check based on the "eepmisc" register
+(which is part of the EEPROM data). When bit 0 is set, then the EEPROM
+format specific values are in "big endian". This is also done by the
+FreeBSD kernel, see [0] for example.
+
+This allows us to parse EEPROMs with the "correct" magic bytes but
+swapped EEPROM format specific values. These EEPROMs (mostly found in
+lantiq and broadcom based big endian MIPS based devices) only worked
+due to platform specific "hacks" which swapped the EEPROM so the
+magic was inverted, which also enabled the format specific swapping.
+With this patch the old behavior is still supported, but neither
+recommended nor needed anymore.

+Subject: [v2 PATCH 7/7] ath9k: define all EEPROM fields in Little Endian format
+
+The ar9300_eeprom logic is already using only 8-bit (endian neutral),
+__le16 and __le32 fields to state explicitly how the values should be
+interpreted.
+All other EEPROM implementations (4k, 9287 and def) were using u16 and
+u32 fields with additional logic to swap the values (read from the
+original EEPROM) so they match the current CPUs endianness.
+
+The EEPROM format defaults to "all values are Little Endian", indicated
+by the absence of the AR5416_EEPMISC_BIG_ENDIAN in the u8 EEPMISC
+register. If we detect that the EEPROM indicates Big Endian mode
+(AR5416_EEPMISC_BIG_ENDIAN is set in the EEPMISC register) then we'll
+swap the values to convert them into Little Endian. This is done by
+activating the EEPMISC based logic in ath9k_hw_nvram_swap_data even if
+AH_NO_EEP_SWAP is set (this makes ath9k behave like the FreeBSD driver,
+which also does not have a flag to enable swapping based on the
+AR5416_EEPMISC_BIG_ENDIAN bit). Before this logic was only used to
+enable swapping when "current CPU endianness != EEPROM endianness".
+
+After changing all relevant fields to __le16 and __le32 sparse was used
+to check that all code which reads any of these fields uses
+le{16,32}_to_cpu.
