spi: remove completely broken Tegra driver 2012-10-01T12:29:49+00:00 Stephen Warren swarren@nvidia.com 2012-09-28T16:15:48+00:00 536a53a300d0d40152796eefb0a9e6e36ca37f7d The current SPI driver has many issues. Examples are: * Segfaulting on most transfers due to expecting all transfers to have both RX and TX buffers. * Hanging on TX transfers since the whole driver flow is driven by RX DMA completion, but the HW is only told to enable RX for RX transfers. * Use of clk_disable_unprepare() from atomic context. * Once those and other minor issues are fixed, the driver still doesn't actually work. * The driver also implements a deprecated API to the SPI core. For this reason, simply remove the driver completely. This has two advantages: 1) This will remove the last use of Tegra's <mach/dma.h>, which will allow that file to be removed, which is required for single zImage work. 2) The downstream driver is significaly different from the current code. I believe a patch to re-add the downstream driver (with appropriate cleanup) will be much simpler to review if it's a new file rather than randomly interspered with essentially unrelated existing code.
