[PATCH 0/8] ARM: omap4/5: crypto support fixes

[PATCH 0/8] ARM: omap4/5: crypto support fixes

[Tero Kristo]

Hi,

This series fixes a couple of crypto data bugs for omap4/5. It also adds
support for crypto accelerators for omap5; the data for these is just
basically copied over from omap4.

OMAP5 currently appears to be running out of available DMA channels,
SPI/MMC are allocating a huge number of channels permanently in boot and
there are only 32 of them available in total. To mitigate the issue
partly, I have left the DES node disabled by default to save two
channels, if someone needs DES support, it can be easily enabled.
However, it might be useful to actually disable some of the SPI/MMC
nodes to save on the number of channels and to avoid running into any
problems.

-Tero

[PATCH 1/8] ARM: dts: omap4: fix node names for the l4_cm clkctrl nodes

[Tero Kristo]

The node name for these should be clk instead of clock. Otherwise the
clock driver won't be able to map the parent/child relationships
properly, and large number of clocks end up in orphaned state.

Heh this is no longer needed since commit 6c3090520554
("clk: ti: clkctrl: Fix hidden dependency to node name")
that added support for using the compatible name :)

Maybe you are using some older tree? Or else there's
still something wrong somewhere.

I was using 5.7-rc1 as baseline so can't be that.

Ok you can ignore this and patch #2 for omap5 for similar case. It seems 
like the patch 6c3090520554 actually forgot to fix the subclock names, 
and it causes issues in mixed clock node setup. Will post a fix against 
the clock driver shortly.

[PATCH 6/8] ARM: dts: omap5: add DES crypto accelerator node

[Tero Kristo]

OMAP5 contains a single DES crypto accelerator instance. Add node for
this in DT to enable it.

We keep the node disabled for now, as it appears OMAP5 platform is
running out of available DMA channels, and DES is the least interesting
crypto accelerator available on the device.

[PATCH 7/8] ARM: OMAP4: Make L4SEC clock domain SWSUP only

[Tero Kristo]

Commit c2ce5fb3f3f5 ('ARM: OMAP: DRA7xx: Make L4SEC clock domain SWSUP
only') made DRA7 SoC L4SEC clock domain SWSUP only because of power
state transition issues detected with HWSUP mode. Based on
experimentation similar issue exists on OMAP4, so do the same change
for OMAP4 also.
