Avoids getting clocks that are not present. - Add OMAP5 and HSIC mode (Not tested). v8: - Re-arranged patch "USB-ehci-omap-Don-t-free-gpios-that-we-didn-t-reques.patch" to be the first since it is a candidate for stable. - Fixed issues raised by Felipe, i.e. indentation and use of switch () v7: - Updated patch 4 to not hold a spinlock when using clk_get(). - Updated patches 3 and 11 to return -EADDRNOTAVAIL on failure of demv_request_and_ioremap(). v6: - Added USB Host platform data consolidation patch as the first patch. based on request from Tony. - Rebased on v3.8-rc3. v5: - Rebased on top of todays arm-soc/for-next. - Removed the clock merging patch from the list. - Updated patches 14, 19 and 20 to accomodate the above change. - Added patch 22 to fix a build warning. v4: - Added appropriate maintainers in to/cc. - minor print message fix in patch 23 to maintain consistency. v3: - Rebased on arm-soc/for-next commit f979306c4d38d213c6977aaf3b1115e8ded71e3a. - Rearranged patch that get rids of cpu_is_omap..() macros. - Coding style fixes. v2: - Clocks are allocated dynamically based on number of ports available on the platform. - Reduced console spam if non critical clocks are not found on the platform. - Get rid of cpu_is_.. macros from USB host driver. cheers, -roger The following changes since commit 9931faca02c604c22335f5a935a501bb2ace6e20: Linux 3.8-rc3 (2013-01-09 18:59:55 -0800) are available in the git repository at: git://github.com/rogerq/linux.git linux-usbhost13-part Roger Quadros (22): USB: ehci-omap: Don't free gpios that we didn't request mfd: omap-usb-host: Consolidate OMAP USB-HS platform data mfd: omap-usb-tll: Fix channel count detection mfd: omap-usb-tll: Use devm_kzalloc/ioremap and clean up error path mfd: omap-usb-tll: Clean up clock handling mfd: omap-usb-tll: introduce and use mode_needs_tll() mfd: omap-usb-tll: Check for missing platform data in probe mfd: omap-usb-tll: Fix error message mfd: omap-usb-tll: serialize access to TLL device mfd: omap-usb-tll: Add OMAP5 revision and HSIC support mfd: omap_usb_host: Avoid missing platform data checks in suspend/resume mfd: omap-usb-host: Use devm_kzalloc() and devm_request_and_ioremap() mfd: omap-usb-host: know about number of ports from revision register mfd: omap-usb-host: override number of ports from platform data mfd: omap-usb-host: cleanup clock management code mfd: omap-usb-host: Manage HSIC clocks for HSIC mode mfd: omap-usb-host: Get rid of unnecessary spinlock mfd: omap-usb-host: clean up omap_usbhs_init() ARM: OMAP3: clock data: get rid of unused USB host clock aliases and dummies ARM: OMAP4: clock data: get rid of unused USB host clock aliases mfd: omap-usb-host: Don't spam console on clk_set_parent failure mdf: omap-usb-host: get rid of build warning arch/arm/mach-omap2/board-3430sdp.c | 2 +- arch/arm/mach-omap2/board-3630sdp.c | 2 +- arch/arm/mach-omap2/board-am3517crane.c | 2 +- arch/arm/mach-omap2/board-am3517evm.c | 2 +- arch/arm/mach-omap2/board-cm-t35.c | 2 +- arch/arm/mach-omap2/board-cm-t3517.c | 2 +- arch/arm/mach-omap2/board-devkit8000.c | 2 +- arch/arm/mach-omap2/board-igep0020.c | 4 +- arch/arm/mach-omap2/board-omap3beagle.c | 2 +- arch/arm/mach-omap2/board-omap3evm.c | 2 +- arch/arm/mach-omap2/board-omap3pandora.c | 2 +- arch/arm/mach-omap2/board-omap3stalker.c | 2 +- arch/arm/mach-omap2/board-omap3touchbook.c | 2 +- arch/arm/mach-omap2/board-omap4panda.c | 2 +- arch/arm/mach-omap2/board-overo.c | 2 +- arch/arm/mach-omap2/board-zoom.c | 2 +- arch/arm/mach-omap2/cclock3xxx_data.c | 11 - arch/arm/mach-omap2/cclock44xx_data.c | 7 - arch/arm/mach-omap2/usb-host.c | 29 +-- arch/arm/mach-omap2/usb.h | 20 +- drivers/mfd/omap-usb-host.c | 546 +++++++++++++++++----------- drivers/mfd/omap-usb-tll.c | 245 +++++++------ drivers/usb/host/ehci-omap.c | 14 +- include/linux/platform_data/usb-omap.h | 24 +- 24 files changed, 491 insertions(+), 439 deletions(-) Acked-by: Russell King
