From 446cf811c58733c4b68149a0b83f4a258e1719ba Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Wed, 20 Nov 2019 22:34:30 +0100 Subject: [PATCH] ARM: socfpga: Actually put bridges into reset on Gen5 in bridge disable On Gen5, the 'bridge disable' command write 0x0 to brgmodrst register, which releases all bridges from reset, instead of putting all bridges into reset. Fix this by inverting the mask and actually putting the bridges into reset.
