usb: musb: TXMAXP,TXCSR setting in Host mode

2012-01-10T08:50:25+00:00

The TXMAXP and TXCSR registers were not set correctly for the BULK OUT endpoints causing issues in Full speed in Host mode. ST-Ericsson Linux next: NA ST-Ericsson ID: 367049 ST-Ericsson FOSS-OUT ID: Trivial Change-Id: If5f3552235d8909adef4777f08d612df432d8709 Signed-off-by: supriya karanth

ux500: usb:handle connection of microA to A cable

2012-01-04T09:29:41+00:00

Connect Micro-A to phone first,Then connect device usb session should be valid to detect the connected device,Until host cable (micro-A) removal. MUSB session bit is cleared when usb host cable (Micro-A) removal from the phone,Not in case of only device disconnection from the usb host cable.

musb: host: Wait for TXPKTRDY to clear in host

2012-01-04T09:29:40+00:00

MUSB_TXCSR_TXPKTRDY will not get cleared if the data is not on the bus. So, need to wait for it to clear in the DMA completion callback.As per musb datasheet, generally mode 1 needs to be used for data length greater than or equal to max packet size. Bus reset happening due to scsi timeout,since in this case should not return continue for next transfers.

u8500:USB:Handle multiple Link status fn calls

2012-01-04T09:29:40+00:00

During boot time, multiple calls are made to Link status function by otg_set_host and otg_set_peripheral. This in turn calls clock and regulator enabling multiple times which creates problem with the reference count of regulators. Hence this blocks the CPU idle since the regulators are not released properly due to multiple acquire. So, Link status function calls are removed from otg_set_host and otg_set_peripheral which are not needed. The Link status call during boot shall be handled by the ab8500_usb_boot_detect function.

ux500: Change to the u8500 wdt

2011-12-21T15:55:02+00:00

This will change to the u8500 wdt that uses a watchdog in the prcmu to detect hangs on the arm side. This is not enabled by default and will need a userspace deamon that enables it, configure it and kicks it from time to time.

ux500: USB : Save/Restore musb registers correctly

2011-12-21T08:49:16+00:00

In suspended state the registers are not saved and restored properly hence back ported.

ux500: usb: restore INDEX register in resume path

2011-12-21T08:49:01+00:00

Restoring the missing INDEX register value in ux500_restore_context(). without this Hub enumeration is inconsistent, if we do multiple connect/disconnect. ST-Ericsson ID: 364906 ST-Ericsson Linux next: NA ST-Ericsson FOSS-OUT ID: NA Signed-off-by: Thirupathi
