From 6f67c079e61a01d599af34dbb852a4fe99d0f52d Mon Sep 17 00:00:00 2001 From: Birger Koblitz Date: Thu, 21 Jan 2021 15:16:24 +0100 Subject: [PATCH] realtek: add API for the hw tables of RTL83XX/93XX SoCs Add a table API that has per accss register locking and uses register description information to handle all table access through a single set of api calls.
