ath79: add support for kernel 5.4
Signed-off-by: David Bauer <mail@david-bauer.net>
[refreshed]
Signed-off-by: Koen Vandeputte <koen.vandeputte@ncentric.com>
* Sync the patches with the changes done for kernel 4.19
* Use KERNEL_TESTING_PATCHVER
* Refresh the configuration
* Fix multiple compile bugs in the patches
* Only add own ag71xx files for kernel 4.19 and use upstream version for
5.4.
