[PATCH 0/3] Add GPMC and NAND support for dm814x-evm and dra62x-j5eco-evm

[PATCH 0/3] Add GPMC and NAND support for dm814x-evm and dra62x-j5eco-evm

[Tony Lindgren]

Hi all,

Here's support for GPMC and NAND on j5-eco evm and dm814x-evm.
Probably too late for v4.5 merge window , but seems to work here if
somebody wants to play with GPMC.

To test, please use Linux next-20151222 or later and the following
patches:

[PATCH v4] clk: ti: Add support for dm814x ADPLL
[PATCH v2] ARM: dts: Add clocks for dm814x ADPLL

Check that you have CONFIG_COMMON_CLK_TI_ADPLL=y. And then you
probably want to apply this for an unrelated DSS build breakage:

[PATCH] OMAPDSS: fix omapfb build error due missing feat functions declaration

Regards,

Tony
