musb: am35x: Workaround for fifo read issue

2010-08-12T14:40:00Z

AM35x supports only 32bit read operations so we need to have workaround for 8bit and 16bit read operations. Signed-off-by: Ajay Kumar Gupta

musb: MSC host support for AM35x

2010-08-12T14:40:00Z

Tested MSC Host on AM3517EVM. Signed-off-by: Ajay Kumar Gupta

musb: fix compilation warning

2010-07-15T20:11:01Z

Fixes below compilation warning omap3.c: In function 'musb_platform_init': omap3.c:123: warning: implicit declaration of function 'omap3_evm_need_extvbus' Signed-off-by: Ajay Kumar Gupta Acked-by: Remy Bohmer Signed-off-by: Sandeep Paulraj

drivers/usb/host/ohci-hcd: rename readl/writel to ohci_readl/ohci_writel

2010-06-30T19:38:10Z

This avoids a build warning that you see if anyone in the header chain has included io.h (which is coming shortly). The previous code redefined readl/writel; this patch renames it to be specific to ohci. The defines are also moved from ohci-hcd.c to ohci.h. Signed-off-by: Becky Bruce

musb: Program extvbus for OMAP3EVM Rev >= E

2010-06-30T19:37:37Z

OMAP3EVM Rev >=E uses external Vbus supply so setting 'extvbus' to '1' for OMAP3EVM Rev >=E runtime based on EVM revision. CC: Remy Bohmer Signed-off-by: Ajay Kumar Gupta

musb: Add Phy programming for using external Vbus

2010-06-30T19:37:37Z

MUSB PHY on OMAP3EVM Rev >= E uses external Vbus supply to support 500mA of power.We need to program MUSB PHY to use external Vbus for this purpose. Adding 'extvbus' member in musb_config structure which should be set by all the boards where MUSB interface is using external Vbus supply. Also added ULPI bus control register read/write abstraction for Blackfin processor as it doesn't have ULPI registers. CC: Remy Bohmer Signed-off-by: Ajay Kumar Gupta Acked-by: Mike Frysinger

musb: Use name based initialization for musb_config

2010-06-30T19:37:37Z

Changed musb_config initialization for omap3.c, davinci.c and da8xx.c using name of structure fields. This would cause the uninitialized field to be null by default and thus would help in avoiding to init some flags required to be set only for a few selected platforms.

USB OHCI support for at91sam9g45 SoC

2010-06-30T19:37:36Z

Add USB OHCI support for at91sam9g45ekes/at91sam9m10g45ek boards. Note that according to errata from Atmel, OHCI is not operational on the first revision of at91sam9g45 chip. So this patch enables OHCI support for later revisions. Signed-off-by: Sergey Matyukevich

EHCI: zero out QH transfer overlay in ehci_submit_async()

2010-06-29T21:03:40Z

ehci_submit_async() doesn't really zero out the QH transfer overlay (as the EHCI specification suggests) which leads to the controller seeing the "token" field as the previous call has left it, i.e.: - if a timeout occured on the previous call (Active bit left as 1), controller incorrectly tries to complete a previous transaction on a newly programmed endpoint; - if a halt occured on the previous call (Halted bit set to 1), controller just ignores the newly programmed TD(s) and the function then keeps returning error ad infinitum. This turned out to be caused by the wrong orger of the arguments to the memset() call in ehci_alloc(), so the allocated TDs weren't cleared either. While at it, stop needlessly initializing the alternate next TD pointer in the QH transfer overlay... Signed-off-by: Sergei Shtylyov Acked-by: Remy Bohmer
