In order to support new chip rts5228, the definitions of some internal registers and workflow have to be modified. Added rts5228.c rts5228.h for independent functions of the new chip rts5228 Signed-off-by: Ricky Wu <ricky_wu@realtek.com> Link: https://lore.kernel.org/r/20200706070259.32565-1-ricky_wu@realtek.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
