powerpc/usb: fix bug of CPU hang when missing USB PHY clock

2012-10-22T06:25:12Z

when missing USB PHY clock, u-boot will hang during USB initialization when issuing "usb start". We should check USBGP[PHY_CLK_VALID] bit to avoid CPU hanging in this case. Due to controller issue of PHY_CLK_VALID in ULPI mode, we set USB_EN before checking PHY_CLK_VALID, otherwise PHY_CLK_VALID doesn't work. Signed-off-by: Shengzhou Liu Acked-by: Marek Vasut

mx51: Fix USB PHY clocks

2012-10-15T18:54:11Z

The i.MX51 has a single USB PHY clock, while the i.MX53 has two. These 3 clocks have different clock gate control bit-fields. The existing code was correct only for i.MX53, so this patch fixes the i.MX51 use case.

usb: ehci: don't print debug output

This is clearly some sort of debug output and should not be printed during normal operation. Signed-off-by: Lucas Stach

tegra20: port to new ehci interface

2012-10-15T18:54:00Z

EHCI interface now supports more than one controller. Wire up our usb functions to use this new interface. Signed-off-by: Lucas Stach

usb: ehci: rework to take advantage of new lowlevel interface

2012-10-15T18:54:00Z

Kill off ehci-core.h It was used to specify some static controller data. To support more than one controller being active at any time we have to carry the controller data ourselfes. Change the ehci interface accordingly. NOTE: OMAP implemented the ehci stuff a bit backwards and should be fixed to do the same thing as other platforms. But the change for now is at least compile clean. Signed-off-by: Lucas Stach Reviewed-by: Marek Vasut

usb: lowlevel interface change to support multiple controllers

2012-10-15T18:54:00Z

Carry an index in the lowlevel usb functions to make specify the respective usb controller. Also pass through an controller struct from lowlevel_init to the creation of the root usb device of this controller. Signed-off-by: Lucas Stach Reviewed-by: Marek Vasut

usb: do explicit unaligned accesses

2012-09-20T22:05:00Z

usb_hub_descriptor has to be packed as it's used for communication with the device. Member wHubCharacteristics violates the natural alignment rules. Use explicit unaligned access functions for this member. Fixes ARMv7 traping while using USB. v2: fix typo found by Thomas Langer v3: rebased on top of u-boot-usb/master Signed-off-by: Lucas Stach

USB: Fix strict aliasing in ohci-hcd

2012-09-01T14:21:53Z

commit 5f6aa03fda2a0a79940765865c1e4266be8a75f8 USB: Fix complaints about strict aliasing in OHCI-HCD tried to fix this, but gcc4.4 still complains. So, this patch basically reverts the above and does a simpler fix. also, the above commit incorrectly changed /* corresponds to data_buf[4-7] */ datab [1] = 0; to /* corresponds to databuf.u8[4-7] */ databuf.u8[1] = 0; This patch also fixes that.
