Merge branch 'microchip=ksz8-cleanup'
Pieter Van Trappen says: ==================== net: dsa: microchip: rename and clean ksz8 series files The first KSZ8 series implementation was done for a KSZ8795 device but since several other KSZ8 devices have been added. Rename these files to adhere to the ksz8 naming convention as already used in most functions and the existing ksz8.h; add an explanatory note. In addition, clean the files by removing macros that are defined at more than one place and remove confusion by renaming the KSZ8830 string which in fact is not an existing KSZ series switch. Signed-off-by: Pieter Van Trappen <[email protected]> --- v4: - correct once more Kconfig list of supported switches v3: https://lore.kernel.org/netdev/[email protected]/ - rename all KSZ8830 to KSZ88X3 only (not KSZ8863) - update Kconfig as per Arun's suggestion v2: https://lore.kernel.org/netdev/[email protected]/ - more finegrained description in Kconfig and ksz8.c header - add KSZ8830/ksz8830 to KSZ8863/ksz88x3 renaming v1: https://lore.kernel.org/netdev/[email protected]/ ==================== Signed-off-by: David S. Miller <[email protected]>
