[PATCH v2 0/2] serial: 8250/ingenic: Add support for the JZ4750

Posted by Siarhei Volkau 3 years, 5 months ago

JZ4750 and JZ4755 have an extra clock divisor in CGU called CPCCR.ECS.
It needs to be handled properly in the early console driver.

V1 diff:
 - splitted into separate patchset
 - code refactored to avoid peek in CGU register
 - Krzysztof's ack picked
