Subject: [PATCH AUTOSEL 5.7 006/274] drm: bridge: adv7511: Extend list of audio sample rates
Date: Mon,  8 Jun 2020 19:01:39 -0400	[thread overview]

In-Reply-To: <20200608230607.3361041-1-sashal@kernel.org>

From: Bogdan Togorean <bogdan.togorean@analog.com>

[ Upstream commit b97b6a1f6e14a25d1e1ca2a46c5fa3e2ca374e22 ]

be computed accordingly so this commit extend the list up to maximum
supported sample rate.
