The dwc2 driver sets the value of the DWC2 GAHBCFG register to 0x6, which is GAHBCFG_HBSTLEN_INCR4. But different platforms may require different values. In particular, the Broadcom 2835 SOC used in the Raspberry Pi needs a value of 0x10, otherwise the DWC2 controller stops working after a short period of heavy USB traffic. So this patch adds another driver parameter named 'ahbcfg'. The default value is 0x6. Any platform needing a different value should add a DT attribute to set it. This patch also removes the 'ahb_single' driver parameter, since that bit can now be set using 'ahbcfg'. This patch does not add DT support to platform.c, I will leave that to whoever owns the first platform that needs a non-default value. (Stephen?) Signed-off-by:

Remove the use of bus_to_virt() and just fail the transfer if an unaligned buffer with no virtual address is found. AFAIK that can't happen anyway. Also change setting of coherent DMA mask to the normal 32 bits. 31 bits was only needed when calling bus_to_virt() AFAICR. Signed-off-by:

The parameters to dwc2_host_complete() didn't make much sense. The 'context' parameter always came from the ->priv member of the 'dwc2_urb' parameter, and both of those always came from a struct dwc2_qtd. So just pass in the struct dwc2_qtd instead. This also allows us to null out the dwc2_qtd->urb member after it is freed, which the calling code forgot to do in several places, causing random driver crashes from dereferencing the freed pointer. This also requires the calls to dwc2_hc_handle_tt_clear() to be moved before the calls to dwc2_host_complete(), otherwise that routine would do nothing because dwc2_qtd->urb has already been freed.

The changes in this patch will fix the binder interface for use on 64bit machines and stand as the base of the 64bit compat support. The changes apply to the structures that are passed between the kernel and userspace. Most of the changes applied mirror the change to struct binder_version where there is no need for a 64bit wide protocol_version(on 64bit machines). The change inlines with the existing 32bit userspace(the structure has the same size) and simplifies the compat layer such that the same handler can service the BINDER_VERSION ioctl. Other changes make use of kernel types as well as user-exportable ones and fix format specifier issues. The changes do not affect existing 32bit ABI. Signed-off-by:

Since this driver is meant to be used on different types of processors and a portable driver should specify the size a variable expects to be this patch changes the types used throughout the binder interface. We use "userspace" types since this header will be exported and used by the Android filesystem. The patch does not change in any way the functionality of the binder driver. Signed-off-by:

The Android userspace aligns the data written to the binder buffers to 4bytes. Thus for 32bit platforms or 64bit platforms running an 32bit Android userspace we can have a buffer looking like this: platform buffer(binder_cmd pointer) size 32/32 32b 32b 8B 64/32 32b 64b 12B 64/64 32b 64b 12B Thus the kernel needs to check that the buffer size is aligned to 4bytes not to (void *) that will be 8bytes on 64bit machines. The change does not affect existing 32bit ABI. Signed-off-by:

BinderDriverCommands mirror the ioctl usage. Thus the size of the structure passed through the interface should be used to generate the ioctl No. The change reflects the type being passed from the user space-a pointer to a binder_buffer. This change should not affect the existing 32bit user space since BC_FREE_BUFFER is computed as: #define _IOW(type,nr,size) \ ((type) << _IOC_TYPESHIFT) | \ ((nr) << _IOC_NRSHIFT) | \ ((size) << _IOC_SIZESHIFT)) and for a 32bit compiler BC_FREE_BUFFER will have the same computed value. This change will also ease our work in differentiating BC_FREE_BUFFER from COMPAT_BC_FREE_BUFFER. The change does not affect existing 32bit ABI. Signed-off-by: -

This change will fix the BINDER_SET_MAX_THREADS ioctl to use __u32 instead of size_t for setting the max threads. Thus using the same handler for 32 and 64bit kernels. This value is stored internally in struct binder_proc and set to 15 on open_binder() in the libbinder API(thus no need for a 64bit size_t on 64bit platforms). The change does not affect existing 32bit ABI. Signed-off-by:

This change mirrors the userspace operation where struct binder_write_read members that specify the buffer size and consumed size are size_t elements. The patch also fixes the binder_thread_write() and binder_thread_read() functions prototypes to conform with the definition of binder_write_read. The changes do not affect existing 32bit ABI.

After migrating ISA DMA support from the "ni_labpc" module to the new "ni_labpc_isadma" module, the `COMEDI_NI_LABPC_ISA` configuration option no longer depends on `VIRT_TO_BUS`, so remove the dependency. (The new `COMEDI_NI_LABPC_ISADMA` option does depend on `VIRT_TO_BUS` but is not configured manually and is only selected automatically if the `VIRT_TO_BUS` and `ISA_DMA_API` options are set.)
