Subject: [PATCH v2 0/3] i.MX6 LDB mux/divider glitch workaround
Date: Mon, 11 Jan 2016 12:23:56 +0100	[thread overview]
Message-ID: <1452511439-10472-1-git-send-email-p.zabel@pengutronix.de> (raw)

Hi,

just so these don't get forgotten, these patches try to implement the
passed down workaround for a glitch caused by switching the ldb_di_sel
muxes which can lock up the ldb_di_ipu_div dividers.
As far as I am aware, this issue is still not mentioned in the chip
errata.

Changes since v1:
 - Rebased onto v4.4
 - Enabled workaround on i.MX6Q revision 1.0, too, but disabled the
   PLL5_VIDEO_DIV parent in that case.

v1 can be found here:
    https://patchwork.kernel.org/patch/5574731/
    https://patchwork.kernel.org/patch/5574741/
    https://patchwork.kernel.org/patch/5574751/

regards
Philipp
