Subject: [PATCH 36/50] drm/rockchip: dw_hdmi: Use auto-generated tables
|
|
|
|
The previous tables for mpll_cfg and curr_ctrl were created using the
|
|
20-pages of example settings provided by the PHY vendor. Those
|
|
example settings weren't particularly dense, so there were places
|
|
where we were guessing what the settings would be for 10-bit and
|
|
12-bit (not that we use those anyway). It was also always a lot of
|
|
extra work every time we wanted to add a new clock rate since we had
|
|
to cross-reference several tables.
|
|
|
|
In <https://crrev.com/c/285855> I've gone through the work to figure
|
|
out how to generate this table automatically. Let's now use the
|
|
automatically generated table and then we'll never need to look at it
|
|
again.
|
|
|
|
We only support 8-bit mode right now and only support a small number
|
|
of clock rates and I've verified that the only 8-bit rate that was
|
|
affected was 148.5. That mode appears to have been wrong in the old
|
|
table.
