This patch series adds device tree support for MUSB and device
tree support for all the related modules to get MUSB working in
OMAP platform.
A new omap-usb2 phy driver has been added (with only dt suppport)
to perform phy configurations. Previously this configuration was
performed by twl6030, using pdata function pointers.
With the addition of omap-usb2 to perform phy configurations,
twl6030 is made as a comparator driver to detect VBUS and ID events
and notify it to the glue layer.
musb core is _NOT_ yet converted to support device tree support as it
would need lot of driver re-design because of its enormous use of
function pointers. That will be in _TO DO_ list.
Changes from RFC:
Removed the dependency on [RFC PATCH 00/11] OMAP System Control Module.
Writing to control module register is now handled in otg driver itself.
Once the system control module driver get upstreamed, I'll send a patch
to make use of API's in control module driver to write to control
module register.
This series was developed on
git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb.git xceiv
This patch series depends on
[RFC PATCH v2 0/2] omap: add ocp2scp as a misc driver.
there is still some discussion on where to place the ocp2scp driver.
Once that gets finalized, I'll resend this patch series again with that
adaptaion.
Performed MUSB device mode testing on OMAP4 panda, OMAP4 SDP
and OMAP3 beagle.
