Subject: [PATCH v2 84/91] drm/vc4: hdmi: Adjust HSM clock rate depending on pixel rate
Date: Fri, 24 Apr 2020 17:35:05 +0200 [thread overview]
Message-ID: <3a3af29a36bec4161f40f3edcd5cacdfbfc7a9d8.1587742492.git-series.maxime@cerno.tech> (raw)
In-Reply-To: <cover.d1e741d37e43e1ba2d2ecd93fc81d42a6df99d14.1587742492.git-series.maxime@cerno.tech>
The HSM clock needs to be setup at around 101% of the pixel rate. This
was done previously by setting the clock rate to 163.7MHz at probe time and
only check in mode_valid whether the mode pixel clock was under the pixel
clock +1% or not.
However, with 4k we need to change that frequency to a higher frequency
than 163.7MHz, and yet want to have the lowest clock as possible to have a
decent power saving.
Let's change that logic a bit by setting the clock rate of the HSM clock
to the pixel rate at encoder_enable time. This would work for the
BCM2711 that support 4k resolutions and has a clock that can provide it,
but we still have to take care of a 4k panel plugged on a BCM283x SoCs
that wouldn't be able to use those modes, so let's define the limit in
the variant.
