[Tony Lindgren]

Hi all,

Here are few ti81xx related improvments for v4.6 merge window.

Regards,

Tony

[PATCH 1/4] ARM: OMAP2+: Fix hwmod clock for l4_ls

[Tony Lindgren]

Looks like we have few cases with wrong clock, and some
entries with missing clock. It should always be sysclk6
for the l4_ls instance.

FYI, applying this into omap-for-v4.6/fixes-not-urgent, and
the rest of the series into omap-for-v4.6/soc and dt
branches.
