Hi, Here is the third round of the OMAP SSI driver patches. Changes since RFCv2: * Move DT data from omap34xx.dtsi to omap3.dtsi Nokia N9 uses an omap3630 and ssi for modem connection, thus SSI seems to be part of all OMAP3 SoCs. * Move DT documentation to the driver patch * Update wording in DT documentation I just applied Stephen Warrens suggestions * Removal of omap_pm_get_dev_context_loss_count as demanded by Tony Lindgren For now there is no context loss support in the driver, since I do not have enough information about the chip to support this via registers. * Dropped useless "default n" from KConfig * Add support for HSI client registration via DT * Register hsi-char as ssi client for Nokia N900 Currently only hsi-char client is available in the mainline kernel, but for the Nokia N900 two more clients will be needed: ssi-protocol and cmt-speech. Those will be added with their own patchset. * Use ida_simple_get for device id, since DT does not setup pd->id * Fixed SSI interrupt numbers in omap3.dtsi I subtracted OMAP_INTC_START before, but the original patch did not yet have OMAP_INTC_START added. * Fixed compilation as kernel modules * Fixed reload of kernel modules * Added module dependency: omap_ssi_port needs omap_port TODO: * Central Message Queue I did not yet implement a central message queue in the HSI framework. I will do this after Nokia N900 modem is working in the mainline kernel, since that makes testing easier. * Get clock data from DT This depends on a patchset, which is not yet part of any kernel tree. Apart from that I don't know which clocks will be needed. That depends on the implementation of the hwmod DTification (see next point) * Remove the hwmod DT hack This depends on some future work merging hwmod data into DT.
