H A D | vid-pll-div.c | 6620f45f Wed Mar 27 10:13:48 CDT 2019 Neil Armstrong <narmstrong@baylibre.com> clk: meson: vid-pll-div: remove warning and return 0 on invalid config
The vid_pll_div is a programmable fractional divider, but vendor gives a limited of known configuration value and it's corresponding fraction.
Thus when at reset value (0) or unknown value, we cannot determine the result rate.
The initial behaviour was to print a warning, but the warning triggers at each boot and when the clock tree is refreshed.
This patch moves the print to debug and returns 0 instead of the parent rate.
