2017-04-25ehci-ppc4xx: Prepare for usage of readl()/writel() accessorsAlexey Brodkin
We used to have opencoded ehci_readl()/writel() which required no external functions to be called. Now with attempt to switch to generic readl()/writel() accessors we see a missing declaration of those accessors in ehci-ppc4xx. Something like that happens if applied http://patchwork.ozlabs.org/patch/726714/: ---------------->8--------------- CC drivers/usb/host/ehci-ppc4xx.o drivers/usb/host/ehci-ppc4xx.c: In function 'ehci_hcd_init': drivers/usb/host/ehci-ppc4xx.c:23:3: warning: implicit declaration of function 'readl' [-Wimplicit-function-declaration] HC_LENGTH(ehci_readl(&(*hccr)->cr_capbase))); ^ ---------------->8--------------- Signed-off-by: Alexey Brodkin <[email protected]> Cc: Tom Rini <[email protected]> Cc: Marek Vasut <[email protected]> Cc: Stefan Roese <[email protected]> Reviewed-by: Stefan Roese <[email protected]>

2017-04-14usb: dwc2: invalidate the dcache before starting the DMAEddie Cai
We should invalidate the dcache before starting the DMA. In case there are any dirty lines from the DMA buffer in the cache, subsequent cache-line replacements may corrupt the buffer in memory while the DMA is still going on. Cache-line replacement can happen if the CPU tries to bring some other memory locations into the cache while the DMA is going on.

2017-04-14usb: dwc3: gadget: make cache-maintenance on event buffers more robustPhilipp Tomsich
Merely using dma_alloc_coherent does not ensure that there is no stale data left in the caches for the allocated DMA buffer (i.e. that the affected cacheline may still be dirty). The original code was doing the following (on AArch64, which translates a 'flush' into a 'clean + invalidate'): # during initialisation: 1. allocate buffers via memalign => buffers may still be modified (cached, dirty) # during interrupt processing 2. clean + invalidate buffers => may commit stale data from a modified cacheline 3. read from buffers This could lead to garbage info being written to buffers before reading them during even-processing. To make the event processing more robust, we use the following sequence for the cache-maintenance: # during initialisation: 1. allocate buffers via memalign 2. clean + invalidate buffers (we only need the 'invalidate' part, but dwc3_flush_cache() always performs a 'clean + invalidate') # during interrupt processing 3. read the buffers (we know these lines are not cached, due to the previous invalidation and no other code touching them in-between) 4. clean + invalidate buffers => writes back any modification we may have made during event processing and ensures that the lines are not in the cache the next time we enter interrupt processing Note that with the original sequence, we observe reproducible (depending on the cache state: i.e. running dhcp/usb start before will upset caches to get us around this) issues in the event processing (a fatal synchronous abort in dwc3_gadget_uboot_handle_interrupt on the first time interrupt handling is invoked) when running USB mass storage emulation on our RK3399-Q7 with data-caches on.

2017-04-14usb: dwc3: ensure consistent types for dwc3_flush_cachePhilipp Tomsich
The dwc3_flush_cache() call was declared and used inconsistently: * The declaration assumed 'int' for addresses (a potential issue when running in a LP64 memory model). * The invocation cast the address to 'long'. This change ensures that both the declaration and usage of this function consistently uses 'uintptr_t' for correct behaviour even when the allocated buffers (to be flushed) reside outside of the lower 32bits of memory.
