This enables UBI+UBIFS to handle the NAND MTDs, including the useful
MTD_UBI_BLOCK.

[PATCH v2] ARM: davinci: da8xx-dt: Add ti-aemif lookup for clock matching

[Karl Beldan]

The davinci boards don't have their clocks in DT yet and getting a clock
with a null con_id will fail, unless registering them as clk_lookups.
This registers the aemif clock for the ti-aemif memory driver.

The current aemif lookup entry resolving to the same clock:
    'CLK(NULL,               "aemif",        &aemif_clk)'
is currently used by davinci_nand and remains for non-DT and backward
compatibility.

Currently the davinci boards only configure the AEMIF in case of non-DT
boot, via some code in mach-davinci.
This change will allow DT-based davinci platforms to do the same, via
the ti-aemif memory driver code.

 Sekhar, please note that commit 31e3a881 ("ARM: dts: da850,da850-evm:

This statement is true, but I am not sure why you limit it to those
clocks with null con_id. On DaVinci, all clocks need to be registered
via a clk_lookup entry. Else clk_get() will fail.

So can I just edit this to:

"
The davinci boards don't have their clocks in DT yet and getting a clock
will fail, unless registering them as clk_lookups.
"

while applying?

yes, noted. While sending the pull request to ARM-SoC, I send the SoC
