v3 cover ARM: add omap3 INCOstartec board support

This set of patches adds board support for an omap3 system from INCOstartec. It's based on next-20140124.

Due to a regression since next-20140115 the following errors are present:

- pin sys_clkout2, which gets configured to 24 Mhz by the fourth patch in this set, erroneously outputs only 12 Mhz.
Just out of curiosity, configuring it to 48 Mhz puts out desired 24 Mhz.

- omap_dss, which gets configured by the third patch in this set, fails to do 'dss_set_fck_rate(fck);' in drivers/video/omap2/dss/dss.c:dss_setup_default_clock() which leads to:

    | omapdss_dss: probe of omapdss_dss failed with error -22
    | omapdss CORE error: Failed to initialize DSS platform driver
    | panel-dpi panel-dpi.0: failed to find video source 'dpi.0

Both regressions seem to have something to do with the clock framework. Could this be related to the DT clock conversion patches?

Changes compared to previous version (v3):
- rebased on next-20140124
- use pinctrl macros OMAP3_WKUP_IOPAD, OMAP3_CORE1_IOPAD and OMAP3630_CORE2_IOPAD
- use same convention for all comments
- dss-quirk: name twl4030 VPLL2 regulator as vdds_dsi
- fix style
Changes compared to previous version (v2):
- rebased on next-20140122 from next-20140115
- using omap36xx.dtsi instead of unsupported 1ghz omap37xx100
Initial version (v1):
- based on next-20140115

PATCH v3 2/4 ARM: dts: omap3: Add support for INCOstartec DBB056 baseboard

In reply to Christoph Fritz

INCOstartec LILLY-DBB056 is a carrier board (baseboard) for computer-on-module LILLY-A83X.

This patch adds device-tree support for most of its features.

PATCH v3 3/4 ARM: OMAP2+: add legacy display for omap3 DBB056

In reply to Christoph Fritz

Full device tree support for omapdss is not yet accomplished. Until then, init display by legacy platform code.

PATCH v3 4/4 ARM: OMAP2+: Add pdata quirk for sys_clkout2 for omap3 DBB056

In reply to Christoph Fritz

Full device tree support for clock control, especially to set frequencies, is not yet accomplished. Until then, configure the 24Mhz of sys_clkout2 to feed an USB-Hub here.

v3 cover ARM: add omap3 INCOstartec board support

In reply to Christoph Fritz
Quoted 13 lines · Christoph Fritz

This set of patches adds board support for an omap3 system from INCOstartec. It's based on next-20140124.

Due to a regression since next-20140115 the following errors are present:

- pin sys_clkout2, which gets configured to 24 Mhz by the fourth patch in this set, erroneously outputs only 12 Mhz.
Just out of curiosity, configuring it to 48 Mhz puts out desired 24 Mhz.

- omap_dss, which gets configured by the third patch in this set, fails to do 'dss_set_fck_rate(fck);' in drivers/video/omap2/dss/dss.c:dss_setup_default_clock() which leads to:

Quoted 6 lines
    | omapdss_dss: probe of omapdss_dss failed with error -22
    | omapdss CORE error: Failed to initialize DSS platform driver
    | panel-dpi panel-dpi.0: failed to find video source 'dpi.0

Both regressions seem to have something to do with the clock framework. Could this be related to the DT clock conversion patches?

Now with dt clock conversion fixes on its way, any chance to get this upstream?
