caldata_die "board $board is not supported yet"
In lantiq, ath9k caldata extraction is implemented to work in two alternate "modes", the standard one and another one with swapped byte pairs. This rearranges the functions so "standard" use is based on the caldata.sh library, while only a single local function is required for the special case. Note that while the parameter for switching between normal and swab is removed, the size of the caldata is added to the function calls to stay consistent. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de> --- v2: - Added this patch (previously separate [5/5] lantiq: modify ath9k caldata extraction to reuse caldata.sh) - Made size in caldata_extract_swap a parameter to match other functions v3: - Rebase, no other changes --- .../etc/hotplug.d/firmware/12-ath9k-eeprom | 62 +++++-------------- 1 file changed, 15 insertions(+), 47 deletions(-)
