Subject: i2c: mediatek: Fix generic definitions for bus frequency
Git-commit: ff6f3aff46beb3c29e0802cffcc559e1756c4814
Patch-mainline: v5.9-rc6
References: jsc#SLE-16106
The max frequency of mediatek i2c controller driver is
I2C_MAX_HIGH_SPEED_MODE_FREQ, not I2C_MAX_FAST_MODE_PLUS_FREQ.
Fix it.
Fixes: 90224e6468e1 ("i2c: drivers: Use generic definitions for bus frequencies")
