| * | | usb: musb: avoid FADDR read accessSebastian Andrzej Siewior2012-10-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is part of the workaround for AM35x advisory Advisory 1.1.20. The advisory says that the IPSS bridge can't handle 8 & 16 bit read access. An 8bit read access to FADDR results in an 32bit read access which also reads INTRTX and therefore may lose interrupts. This patch removes any reads to FADDR as they are not really required. Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: Felipe Balbi <balbi@ti.com>

* | usb: musb: am35xx: drop spurious unplugging a deviceStefano Babic2012-10-15
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On AM3517, tx and rx interrupt are detected together with the disconnect event. This generates a kernel panic in musb_interrupt, because rx / tx are handled after disconnect. This issue was seen on a Technexion's TAM3517 SOM. Unplugging a device, tx / rx interrupts together with disconnect are detected. This brings to kernel panic like this: [ 68.526153] Unable to handle kernel NULL pointer dereference at virtual address 00000011 [ 68.534698] pgd = c0004000 [ 68.537536] [00000011] *pgd=00000000 [ 68.541351] Internal error: Oops: 17 [#1] ARM [ 68.545928] Modules linked in: [ 68.549163] CPU: 0 Not tainted (3.6.0-rc5-00020-g9e05905 #178) [ 68.555694] PC is at rxstate+0x8/0xdc [ 68.559539] LR is at musb_interrupt+0x98/0x858 [ 68.564239] pc : [<c035cd88>] lr : [<c035af1c>] psr: 40000193 [ 68.564239] sp : ce83fb40 ip : d0906410 fp : 00000000 [ 68.576293] r10: 00000000 r9 : cf3b0e40 r8 : 00000002 [ 68.581817] r7 : 00000019 r6 : 00000001 r5 : 00000001 r4 : 000000d4 [ 68.588684] r3 : 00000000 r2 : 00000000 r1 : ffffffcc r0 : cf23c108 [ 68.595550] Flags: nZcv IRQs off FIQs on Mode SVC_32 ISA ARM Segment ke Note: this behavior is not seen with a USB hub, while it is easy to reproduce connecting a USB-pen directly to the USB-A of the board.

It's the introduction of the first multiplatform support on ARM, and with this (and the later branch) merged, it is now possible to build one kernel that contains support for highbank, vexpress, mvebu, socfpga, and picoxcell. More platforms will be convered over in the next few releases. Two critical last things had to be done for this to be practical and possible: * Today each platform has its own include directory under mach-<mach>/include/mach/*, and traditionally that is where a lot of driver/platform shared definitions have gone, such as platform data structures. They now need to move out to a common location instead, and this branch moves a large number of those out to include/linux/platform_data. * Each platform used to list the device trees to compile for its boards in mach-<mach>/Makefile.boot. Both of the above changes will mean that there are some merge conflicts to come (and some to resolve here). It's a one-time move and once it settles in, we should be good for quite a while. Sorry for the overhead."

It fixes a bunch of mistakes errors which nobody has triggered before, so I'm not Ccing stable tree. We are finally improving OMAP's VBUS/ID Mailbox usage so that we can introduce our PHY drivers properly. Also, we're adding support for multiple instances of the MUSB IP in the same SoC, as seen on some platforms from TI which have 2 MUSB instances. Other than that, we have some small fixes like not kicking DMA for a zero byte transfer, or properly handling NAK timeout on MUSB's host side, and the enabling of DMA Mode1 for any transfers which are aligned to wMaxPacketSize. All patches have been pending on mailing list for a long time and I don't expect any big surprises with this pull request.
