[PATCH 0/3] OMAP4: DSS OMAP4 hwmod support

[PATCH 0/3] OMAP4: DSS OMAP4 hwmod support

[Sumit Semwal]

This patch series enables support for OMAP4 DSS, and adds hwmod support
for dss, dispc, dsi1, dsi2, hdmi, rfbi and venc hwmods.

In OMAP4 there are severals IPs that can be reached by differents
interconnect paths depending of the access initiator (MPU vs. SDMA).

In the case of the DSS, both L3 direct path and L4 CFG path can be
used to access all the DSS IPs.
dss is also considered as an IP as dispc, rfbi, and named as dss_dss.

TODO:
This patch doesn't handle the opt clocks via hwmod - there will be a separate
patch series which will take opt clock roles from hwmod, populate them in
the device structure, so that the driver can ask for relevant opt-clocks.

Also TBD is the migration to pm_runtime APIs, which need to be adapted a little
for handling DSS-family of clocks completely.

[PATCH 2/3] OMAP4: hwmod data: add DSS DISPC DSI1,2 RFBI HDMI VENC

[Sumit Semwal]

From: Benoit Cousson <b-cousson@ti.com>

Add dss, dispc, dsi1, dsi2, hdmi, rfbi and venc hwmods.
In OMAP4 there are severals IPs that can be reached by differents
interconnect paths depending of the access initiator (MPU vs. SDMA).
In the case of the DSS, both L3 direct path and L4 CFG path can be
used to access all the DSS IPs. The two ocp_ip already exists to support
the two address spaces.

      +------------+-- L3_MAIN --+ MPU
  IP  |            |
      +-- L4_CFG --+

L3 main address range is specified first, since it is used by default.
dss is also considered as an IP as dispc, rfbi, and named as dss_dss.

[PATCH 3/3] OMAP4: DSS2: Add hwmod device names for OMAP4.

[Sumit Semwal]

Add hwmod device names for OMAP4; this enables device build for omap4 dss
hwmod IPs.

This series is confusing as the 3 patches here do not do all the things
described here.

It also doesn't apply to the master branch (e.g. PATCH 3/3 modifies
display.c, which doesn't exist until your other series.)

Please take care when writing these cover letters to be sure they are
accurate, otherwise reviewers/maintainers can't help but be confused
about what is going on.

First up, apologies for submitting these patches while the dependent
patch series is still under discussion - I guess I should've waited
till the hwmod patch series is accepted, but I thought mentioning the
dependency might be sufficient. will take care in future.

Though I don't quite understand why you think that the 3 patches don't
do all that is described.

The first patch enables building DSS for OMAP4 by updating the Kconfig
accordingly.
The second patch enables hwmod support for all the dss IP hwmod
devices, and the third one enhances the hwmod lookup to lookup OMAP4
devices as well.

If you could tell me what is missing or extra, I would correct that
and send an updated version.

Thanks, and best regards,
~Sumit.

No, stating the dependency in the changelog/cover letter is sufficient.

This is my fault for not fully parsing your description of the
dependencies and trying to apply directly to linux-omap.  My apologies.

Sorry for the noise,
