[PATCH 0/3] Add minimal support for dra62x j5-eco

[PATCH 0/3] Add minimal support for dra62x j5-eco

[Tony Lindgren]

Hi all,

Here are minimal changes to add support for dra62x also known as
jacinto 5 or j5-eco. We can leverage the dm814x support being fixed in
mainline kernel also for dra62x. Compared to dm814x, dra62x has a
bit different clocks and devices.

To boot j5-eco evm, you need the the patches below on v4.4-rc3 with
the following additional patches posted earlier.

Basic clock driver for dm814x:

Fixes for dm814x:

http://marc.info/?l=linux-omap&m=144901336001085&w=2

And also make sure you have the initcall level change patch that
is needed for having omap clock drivers as regular Linux device
drivers:

[PATCH 1/3] ARM: OMAP2+: Fix SoC detection for dra62x j5-eco

[Tony Lindgren]

We can boot dra62x j5-eco using the dm814x code as the clocks and
devices are mapped in the device tree. The dra62x is also known
as jacinto 5.

We may want to add separate soc_is macros for dra62x if needed,
but this gets us to the point where we can boot dra62x with just
dts changes.

Let's also print out the unknown hawkeye register to make things
a bit easier for new SoC variants.

I'm pretty sure the "eco" in the name isn't optional. As far as I know:
jacinto 5 = dra65x ~ dm814x
jacinto 5 eco = dra62x ~ dm811x
jacinto 5 entry = dra61x/60x ~ am335x

Here ~ means equivalence modulo efuse bits.

My knowledge of TI's automotive processors is limited however, as is
public documentation, so perhaps someone from TI can ack or nak this.

OK I'll update to to use "jacinto 5 eco" specifically to avoid more
confusion.
