Subject: [PATCH] ARM: OMAP3: Add missing enable/disable for EMU clock
Date: Thu, 20 Dec 2012 16:43:46 -0600 [thread overview]
Message-ID: <1356043426-7381-1-git-send-email-jon-hunter@ti.com> (raw)
The ETM/ETB drivers for OMAP3, enable the emu_src_ck clock in order
to access the ETM/ETB hardware. The emu_src_ck should enable the EMU
clock domain so that the ETM/ETB hardware is accessible. However,
currently when enabling the emu_src_ck the EMU clock domain is not
being enabled and so the ETM/ETB drivers are failing. Add enable/disable
clock functions to enable the EMU clock domain when enabling the
emu_src_ck.
