6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Luca Weiss <luca.weiss@xxxxxxxxxxxxx>
[ Upstream commit 3414f41a13eb41db15c558fbc695466203dca4fa ]
Both gpll6 and gpll7 are parented to CXO at 19.2 MHz and not to GPLL0
which runs at 600 MHz. Also gpll6_out_even should have the parent gpll6
and not gpll0.
Adjust the parents of these clocks to make Linux report the correct rate
and not absurd numbers like gpll7 at ~25 GHz or gpll6 at 24 GHz.
Corrected rates are the following:
gpll7 807999902 Hz
gpll6 768000000 Hz
gpll6_out_even 384000000 Hz
gpll0 600000000 Hz
gpll0_out_odd 200000000 Hz
gpll0_out_even 300000000 Hz
And because gpll6 is the parent of gcc_sdcc2_apps_clk_src (at 202 MHz)
that clock also reports the correct rate now and avoids this warning:
[ 5.984062] mmc0: Card appears overclocked; req 202000000 Hz, actual 6312499237 Hz
