Subject[PATCH v4 00/13] Tegra124 EMC (external memory controller) support
Date
Hello,

in this v4 you can find these changes:

* Adapt to changes in the latest version of Thierry's IOMMU series

* OF bindings don't specify any unit-address or naming for the timings and timing subnodes. This is
in line with how the display timings are specified.

* Misc improvements on error handling and reporting

* Misc style fixes

* Adds a bit more information on the registers that need to be specified for each timing, and points
to the TRM for more details.

It depends on Thierry's MC patches at [0] and a branch can be found at [1]. So
far it has been tested only on a Jetson TK1.

Patch 1: Removes the old EMC clock, that was unused and not functional

Patch 2: Documents bindings for the new long-ram-code property

Patch 3: Adds API for reading the ram code

Patches 4 to 6: Document OF additions

Patch 7: Adds EMC node to Tegra124 DT

Patch 8: Adds timings for Jetson TK1 board

Patch 9: Adds functions to the MC driver so the EMC driver can stay within its
own registers

Patch 10: Adds the actual EMC driver, making use of the new MC API

Patch 11: Adds EMC clock driver, making use of API provided by the EMC driver

Patch 12: Adds debugfs entry for getting and setting the EMC rate

Patch 13: On Tegra124, have the EMC clock be the parent of the MC clock

Regards,

Tomeu
