[PATCH 0/3] ARM: OMAP2+: devices: Silence hwmod lookup failures (dmic/mcpdm)

[Peter Ujfalusi]

Hi,

Small patches to silence the hwmod lookup failures in case when we boot the
kernel on boards where the IPs are not present (OMAP2/3 vs McPDM, DMIC,
HDMI audio).

Regards,
Peter

[PATCH 1/3] ARM: OMAP2+: devices: Do not print error when McPDM hwmod lookup fails

[Peter Ujfalusi]

It means that the SoC does not have McPDM IP.

[PATCH 3/3] ARM: OMAP2+: devices: Do not print error when dss_hdmi hwmod lookup fails

[Peter Ujfalusi]

The dss_hdmi hwmod is used to create the HDMI audio device for OMAP4+
When we boot the kernel we can silently ignore the failure since the IP
does not exist on them.
