Message-ID: <20230726160441.101566-2-afd@ti.com>

Subject: [PATCH v2 2/2] ARM: keystone: Merge PM function into main support file
The one function left in this file does not justify a whole extra
file nor the keystone.h support file used to forward declare that
function. Merge this into the main keystone.c file.
Signed-off-by: Andrew Davis <afd@...com>
---
Changes for v2:
- Make keystone_pm_runtime_init static (kernel test robot <lkp@...el.com>)
- Rebase on next to get patch dropping headers
- Drop all taken patches after this one in series
