Subject: [PATCH 084/146] clk: sunxi-ng: h3/h5: Add max. rate constraint to
|
|
pll-video
|
|
|
|
As it turns out, pll-video can be set to higher rate that it is really
|
|
supported by HW.
|
|
|
|
For example, one monitor requested 185.58 MHz pixel clock. Clock
|
|
framework calculated that minimum rate error would be when pll-video
|
|
is set to 2040 MHz. This is clearly out of specs.
|
|
|
|
Both H3 and H5 user manuals specify 600 MHz as maximum supported rate.
|
|
However, BSP clock drivers allow up to 912 MHz and 1008 MHz
|
|
respectively. Here 912 MHz is chosen because user manuals were already
|
|
proven wrong once for lower limits.
