Subject: ARM: OMAP4: hwmod data: add aes1
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9a9ded89ad9ca46382a4ea63f36f830bccfab4ec;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ARM: OMAP4: hwmod data: add aes1

This fixes the following error during kernel boot:

platform 4b501000.aes: Cannot lookup hwmod 'aes1'

Unfortunately the AES module is only documented partly
in the OMAP4430 TRM. I found an old patch from Joel,
which I took over and updated for currently mainline.
