Hi all,
This series introduces the support for the Marvell Berlin nand controller. It is based on top of v3.19-rc6 and was tested on the Marvell Berlin BG2Q DMP board.
The support is added into the existing pxa3xx nand controller. Some additions were done in order to get this controller working: - Support for a non mandatory ECC clock has been added. - The Berlin nand controller needs to poll the status register. - Sequences of commands are quite different in order to perform read and write operations.
Changes were done in order to avoid impacting other controllers using this driver, but I'd like people actually using the pxa3xx nand driver to test theses patches to ensure no harm was done. A specific Berlin nand cmd function has been added to deal with most of the Berlin specific code.
Because of a bug in the Berlin clock driver, this series requires the fix provided by Jisheng Zhang, which is already in v3.19-rc6 (b71e8ecd57c8aae5b1815782c47b74ffe3efc09a).
Thanks!
Antoine
