Modify OMAP McBSP driver to use omap hwmod framework and pm runtime APIs. Created on top of linux OMAP master (linux-omap-2.6 :master) Tested on OMAP4430 and OMAP3430 SDP boards. Verified that this patch series does not break the OMAP1 build. Highlights * McBSP is designed to use multiple hwmods for a single device when the McBSP device has sidetone feature. * To avoid funcionality break of OMAP1 McBSP in between the series and to keep the patches readable, implementation was done in two steps: - First modify mcbsp driver to use platform_get* APIs - then convert it to use hwmod framework for OMAP2+. * API's like omap_device_noidle() and omap_device_default_idle() is used to change the SYCONFIG register bits. This change is done to align with the discussion on [2] * Use '.rev' of omap_hwmod class to identify OMAP3 specific settings * Use *ST_* macros for idlest_idle bit * Incorporate other general review comments provided for hwmod adpatation of other OMAP driver's (eg., do pdata free after a omap_device_build()) * Retain fclk even after pm_runtime adaptation to facilitate switching of functional clock from one source to another Discussions related to the first RFC patch can be found at [1] [1]: http://www.mail-archive.com/linux-omap@xxxxxxxxxxxxxxx/msg36743.html [2]: http://www.mail-archive.com/linux-omap@xxxxxxxxxxxxxxx/msg39615.html Charulatha V (3) OMAP2420: hwmod data: Add McBSP OMAP2430: hwmod data: Add McBSP OMAP3: hwmod data: Add McBSP Benoit Cousson (1) OMAP4: hwmod data: Add McBSP Kishon Vijay Abraham I (6): OMAP: hwmod: Add member 'name' to omap_hwmod_addr_space struct OMAP: McBSP: Convert McBSP to platform device model OMAP3: hwmod: add dev_attr for McBSP sidetone OMAP2+: McBSP: hwmod adaptation for McBSP OMAP: McBSP: use omap_device APIs to modify SYSCONFIG OMAP: McBSP: Add pm runtime support arch/arm/mach-omap1/mcbsp.c | 383 +++++++++++++++---- arch/arm/mach-omap2/mcbsp.c | 246 ++++--------- arch/arm/mach-omap2/omap_hwmod.c | 1 + arch/arm/mach-omap2/omap_hwmod_2420_data.c | 167 ++++++++ arch/arm/mach-omap2/omap_hwmod_2430_data.c | 415 ++++++++++++++++++++ arch/arm/mach-omap2/omap_hwmod_3xxx_data.c | 535 ++++++++++++++++++++++++++ arch/arm/mach-omap2/omap_hwmod_44xx_data.c | 320 +++++++++++++++ arch/arm/mach-omap2/prcm-common.h | 4 + arch/arm/plat-omap/devices.c | 10 +- arch/arm/plat-omap/include/plat/mcbsp.h | 26 +- arch/arm/plat-omap/include/plat/omap_hwmod.h | 4 +- arch/arm/plat-omap/mcbsp.c | 143 +++++--- 12 files changed, 1942 insertions(+), 312 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
