2015-03-26bus: ocp2scp: SYNC2 value should be changed to 0x6Kishon Vijay Abraham I1-0/+34
As per the TRMs of AM572x, OMAP4430, OMAP4460, OMAP543x, the value of SYNC2 must be set to 0x6 in order to ensure correct operation. So modified the SYNC2 value of OCP2SCP TIMING register to 0x6 in all the platforms that use OCP2SCP driver except AM437x. Also introduced a new compatible property since we don't want to modify the OCP2SCP TIMING register for AM437x. The sections in TRM where the above caution can be found is mentioned below. AM572x TRM SPRUHZ6 (http://www.ti.com/lit/ug/spruhz6/spruhz6.pdf) under section 26.3.2.2, table 26-26. OMAP4430 TRM SWPU231AP (http://www.ti.com/lit/ug/swpu231ap/swpu231ap.pdf) under section 23.12.6.2.2 , Table 23-1213.

2013-05-31ARM: OMAP2+: Remove omap4 ocp2scp pdataTony Lindgren1-60/+0
This is omap4+ only and no longer needed as omap4+ can be booted using device tree. Also remove the related pdata handling from the driver and the now unneeded platform_data/omap_ocp2scp.h.

2013-01-04Drivers: misc: remove __dev* attributes.Greg Kroah-Hartman1-3/+3
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

2012-11-07drivers: bus: ocp2scp: add pdata supportKishon Vijay Abraham I1-3/+65
ocp2scp was not having pdata support which makes *musb* fail for non-dt boot in OMAP platform. The pdata will have information about the devices that is connected to ocp2scp. ocp2scp driver will now make use of this information to create the devices that is attached to ocp2scp.

2012-08-22drivers: bus: add a new driver for omap-ocp2scpKishon Vijay Abraham I1-0/+88
Adds a new driver *omap-ocp2scp*. This driver takes the responsibility of creating all the devices that is connected to OCP2SCP. In the case of OMAP4, USB2PHY is connected to ocp2scp. This also includes device tree support for ocp2scp driver and the documentation with device tree binding information is updated.
