[LEDE-DEV] ralink i2c / i2s update

[John Crispin]

Hi Michael,

i have been testing the update on real HW and at least the I2C update
breaks the i2c bus on mt7620 and mt7621. i will see if i can find the cause.

if i cant find out the cause i would have to revert
d8202a84096831d4e6e2a522476bd6a0d46e6413. could you also look into this
? the mqmaker witi board for example fails to talk to its RTC with the
i2c update patch applied.
