Subject: [PATCH AUTOSEL 4.4 9/9] drm/nouveau/i2c/g94-: increase NV_PMGR_DP_AUXCTL_TRANSACTREQ timeout
Date: Tue, 14 Jul 2020 10:40:23 -0400	[thread overview]
Message-ID: <20200714144024.4036118-9-sashal@kernel.org> (raw)
In-Reply-To: <20200714144024.4036118-1-sashal-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>

From: Ben Skeggs <bskeggs-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org>

[ Upstream commit 0156e76d388310a490aeb0f2fbb5b284ded3aecc ]

Tegra TRM says worst-case reply time is 1216us, and this should fix some
spurious timeouts that have been popping up.
