Changes invloves: ---------------- 1) Addition of hwmod data for omap2/3/4. 2) McSPI driver hwmod adaptation with cleanup of base address macros and using omap-device API's. 3) Runtime Conversion of McSPI driver.
I accidentally replied to the v4 series about the refresh, but this one
still needs ar refresh.
Specifically, this change from Gregory Clement touches some of the same
code as your patch:

Changes from v4: --------------- 1) 4430 hwmod file alignment based on Benoit's comments. http://www.spinics.net/lists/arm-kernel/msg111215.html 4430 Hwmod file now aligned based on: http://gitorious.org/omap-pm/linux/blobs/pm-wip/ hwmods-omap4-full/arch/arm/mach-omap2/omap_hwmod_44xx_data.c Changes from v3: --------------- 1) Updated proper Author for all patches which was missed in v2. 2) Modified 4430 hwmod data file so that mcspi data gets updated in proper alphabetical order. 3) Update omap2/3 hwmod dat files with SYSS_HAS_RESET_STATUS flag. Changes from v2: --------------- 1) Fixing minor comments and adding ack from Grant Likely. https://patchwork.kernel.org/patch/371321/ https://patchwork.kernel.org/patch/371331/ Changes from v1: --------------- 1) Fixing patch 5/5 comments for hwmod+runtime Split the patch 5/5 to hwmod adaptation and then runtime conversion http://www.mail-archive.com/linux-omap at vger.kernel.org/msg33387.html Testing Updates: ---------------- Was tested using data transfer test module available at: http://dev.omapzoom.org/?p=richo/device_driver_test.git;a=blob;f=mcspi/test_code/ utils/mcspi_modules/omap_mcspi_datatest.c; h=e42ec10c5c844abdde6a7175a268b379fbbdb655; hb=5d9a755d50e58de861c5e8991f2f607bc49b5dc3 This test basically involves MISO <--> MOSI lines looped and data transfer test done using the above test module. System wide suspend and ret/off counts observation, ensured that no behavioral difference with and without this patch series.
