From 74128d801b5165650ae6222e8cf23780fbc55e67 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Thu, 23 Sep 2021 01:09:45 +0200 Subject: watchdog: ux500_wdt: Drop platform data Drop the platform data passing from the PRCMU driver. This platform data was part of the ambition to support more SoCs, which in turn were never mass produced. Only a name remains of the MFD cell so switch to MFD_CELL_NAME().
