2017-07-12bus: omap-ocp2scp: Fix error handling in omap_ocp2scp_probeKishon Vijay Abraham I
The error handling code in omap_ocp2scp_probe fails to invoke pm_runtime_disable and fails to initialize return value in certain cases. Fix it here. Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com> Signed-off-by: Sekhar Nori <nsekhar@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

2015-03-26bus: ocp2scp: SYNC2 value should be changed to 0x6Kishon Vijay Abraham I
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. OMAP4460 TRM SWPU235AB (http://www.ti.com/lit/ug/swpu235ab/swpu235ab.pdf) under section 23.12.6.2.2, Table 23-1213. OMAP543x TRM SWPU249 (http://www.ti.com/lit/pdf/swpu249) under section 27.3.2.2, Table 27-27.

2014-10-20bus: drop owner assignment from platform_driversWolfram Sang
A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
2013-05-30ARM: OMAP2+: Remove omap4 ocp2scp pdataTony Lindgren
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.

2013-01-03Drivers: misc: remove __dev* attributes.Greg Kroah-Hartman
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 I
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. This is needed to fix MUSB regression caused by commit c9e4412a (arm: omap: phy: remove unused functions from omap-phy-internal.c) Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com> Acked-by: Felipe Balbi <balbi@ti.com> [tony@atomide.com: updated comments for regression info] Signed-off-by: Tony Lindgren <tony@atomide.com>

2012-08-22drivers: bus: add a new driver for omap-ocp2scpKishon Vijay Abraham I
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.
