SPI: omap2_mcspi driver (ccdc7bf9) · Commits · 戴 / test

Add OMAP24XX McSPI (Multichannel SPI) controller driver. This driver is tested very well under OMAP GIT tree with N800 - Nokia Internet Tablet, and some other OMAP2 boards. Recent updates included bugfixes, cleanups, speedups, and better conformance to the current SPI programming interface. This doesn't yet understand the third controller instance on the OMAP 2430.
