[PATCH v2 0/2] CQE support for cadence eMMC host controller

Posted by Rohan Joshi via B4 Relay 1 month, 1 week ago

Hi,

This series adds CQE (Command Queue Engine) support for cadence
eMMC host controller. The Cadence controller can support CQE which
is determined by reading a non standard capability register.
Updates to devicetree are also made to identify CQE register space
which may be used by the driver.
