Subject:    [PATCH 08/11] [WIP] ARM: shmobile: r8a7740: Add D4 pm domain support

[Download RAW message or body]

Add support for the D4 power domain.
This domain contains the Coresight-ETM hardware block.

FIXME: D4 is not added, as this breaks resume (dbg_cpu_pm_notify() calls
       reset_ctrl_regs(), which crashes as D4 is powered down, and commit
       0d352e3d006c9589 ("ARM: hw_breakpoint: trap undef instruction
       exceptions in reset_ctrl_regs") doesn't seem to work...)
