Hello Martin
Actually you were right that my patch affects only meson8 family not the all new ones, my bad.
It's clear from the driver code meson_saradc.c and dts files.
I've made an experiment on a113l soc - changingclock_rate inmeson_sar_adc_param and measuring adc channel many times
and with low clockfrequency (priv->adc_clk) time of measurementis high
and vice versa. ADC_CLK_DIV field in SAR_ADC_REG3 is always zero.
Thanks for sharing your findings!
I need to get s805 (meson8) board for example and made experiment on it.
If you don't find any Meson8 (S802)/Meson8b (S805) or Meson8m2 (S812)
board then please provide the code that you used for your experiment
as a patch so I can give it a try on my Odroid-C1 (Meson8b).
Hello Martin
Thanks for the help! I managed to get Odroid-C1 myself. I think it'll be
useful to test further patches.
By the way seems like the board and the sock are not popular anymore...
It remains only to build mainline kernel for meson8 to perform tests.
Hope to be back soon.
Best regards
George
