Subject: [PATCH 5.8 18/38] omapfb: dss: Fix max fclk divider for omap36xx
Date: Mon, 10 Aug 2020 17:19:08 +0200 [thread overview]
Message-ID: <20200810151804.786453607@linuxfoundation.org> (raw)
In-Reply-To: <20200810151803.920113428@linuxfoundation.org>
From: Adam Ford <aford173@gmail.com>
commit 254503a2b186caa668a188dbbd7ab0d25149c0a5 upstream.
The drm/omap driver was fixed to correct an issue where using a
divider of 32 breaks the DSS despite the TRM stating 32 is a valid
number. Through experimentation, it appears that 31 works, and
it is consistent with the value used by the drm/omap driver.
This patch fixes the divider for fbdev driver instead of the drm.
Fixes: f76ee892a99e ("omapfb: copy omapdss & displays for omapfb")
