| * usb: Fix error handling in musb_hcd.cAndrew Murray2013-10-07-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The wait_until_[rx|tx]ep_ready functions return a u8 to indicate success containing the value 0, 1 or -1. This patch changes the return type to an int to accommodate the negative return values. These functions are used in the file using calls such as if (!wait_until... Where a -1 is returned it is mishandled and treated as success instead of a CRC error. This patch addresses this.

| * | spi: exynos: Support word transfersRajeshwari Shinde2013-10-08-15/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since SPI register access is so expensive, it is worth transferring data a word at a time if we can. This complicates the driver unfortunately. Use the byte-swapping feature to avoid having to convert to/from big endian in software. This change increases speed from about 2MB/s to about 4.5MB/s.

| * | spi: exynos: Minimise access to SPI FIFO levelRajeshwari Shinde2013-10-08-12/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Accessing SPI registers is slow, but access to the FIFO level register in particular seems to be extraordinarily expensive (I measure up to 600ns). Perhaps it is required to synchronise with the SPI byte output logic which might run at 1/8th of the 40MHz SPI speed (just a guess). Reduce access to this register by filling up and emptying FIFOs more completely, rather than just one word each time around the inner loop. Since the rxfifo value will now likely be much greater that what we read before we fill the txfifo, we only fill the txfifo halfway. This is because if the txfifo is empty, but the rxfifo has data in it, then writing too much data to the txfifo may overflow the rxfifo as data arrives. This speeds up SPI flash reading from about 1MB/s to about 2MB/s on snow.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For devices that need some time to react after a spi transaction finishes, add the ability to set a delay. Implement this as a delay on the first/next transaction to avoid any delay in the fairly common case where a SPI transaction is followed by other processing.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Qspi controller can have a memory mapped port which can be used for data read. Added support to enable memory mapped port read. This patch enables the following: - It enables exchange of memory map address between mtd and qspi through the introduction of "memory_map" flag. - Add support to communicate to the driver that memory mapped transfer is to be started through introduction of new flags like "SPI_XFER_MEM_MAP" and "SPI_XFER_MEM_MAP_END". This will enable the spi controller to do memory mapped configurations if required.
