Subject: [PATCH v4 0/2] mark spi clocks as critical and enable spi3 clocks
Hi,
I managed to bring some confusion on these two patches, but
finally I managed to find the right solution (which is similar to
the patch version 2).
The real issue was hidden in the spi bus as reported in the
following patch:
https://lkml.org/lkml/2016/7/7/81
This patch in principle replaces the clock_ignore_unused flags in
for the spi and enables the spi3 that in the tm2(e) board will be
connected to the IR remote controller.
Changelog:
V1 -> V2
- the "sclk_spi3" doesn't need to be enabled in boot time as it
is handled by the spi driver itself.
- use the CLK_IS_CRITICAL flag for the ioclk
V2 -> V3
- some more tests has confirmed taht "sclk_spi1,3" need to be
enabled as critical!
- added Chanwoo's review in the second commit.
V3 -> V4
- patch V3 was wrong, back to patch v2.
- reworded the commit of patch no. 1
Thanks,
Andi
