git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC cleanups from Olof Johansson: "This is the branch where we usually queue up cleanup efforts, moving drivers out of the architecture directory, header file restructuring, etc. Sometimes they tangle with new development so it's hard to keep it strictly to cleanups. Some of the things included in this branch are: * Atmel SAMA5 conversion to common clock * Reset framework conversion for tegra platforms - Some of this depends on tegra clock driver reworks that are shared with Mike Turquette's clk tree. * Tegra DMA refactoring, which are shared branches with the DMA tree. * Removal of some header files on exynos to prepare for multiplatform" * tag 'cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (169 commits) ARM: mvebu: move Armada 370/XP specific definitions to armada-370-xp.h ARM: mvebu: remove prototypes of non-existing functions from common.h ARM: mvebu: move ARMADA_XP_MAX_CPUS to armada-370-xp.h serial: sh-sci: Rework baud rate calculation serial: sh-sci: Compute overrun_bit without using baud rate algo serial: sh-sci: Remove unused GPIO request code serial: sh-sci: Move overrun_bit and error_mask fields out of pdata serial: sh-sci: Support resources passed through platform resources serial: sh-sci: Don't check IRQ in verify port operation serial: sh-sci: Set the UPF_FIXED_PORT flag serial: sh-sci: Remove duplicate interrupt check in verify port op serial: sh-sci: Simplify baud rate calculation algorithms serial: sh-sci: Remove baud rate calculation algorithm 5 serial: sh-sci: Sort headers alphabetically ARM: EXYNOS: Kill exynos_pm_late_initcall() ARM: EXYNOS: Consolidate selection of PM_GENERIC_DOMAINS for Exynos4 ARM: at91: switch Calao QIL-A9260 board to DT clk: at91: fix pmc_clk_ids data type attriubte PM / devfreq: use inclusion <mach/map.h> instead of <plat/map-s5p.h> ARM: EXYNOS: remove <mach/regs-clock.h> for exynos ...

2013-12-17usb: gadget: nokia: fix error recovery path for optional functionsAndrzej Pietrasiewicz
In the nokia gadget some USB functions (obex 1 and 2, phonet) are optional. If at the start of nokia_bind_config e.g. fi_phonet is an error pointer, which can happen because we don't fail the bind process if usb_get_function_instance() fails for fi_phonet, then f_phonet is NULL, and phonet_stat = usb_add_function(c, f_phonet); is never called and phonet_stat remains 0. If, in these circumstances, we hit the err_conf label then !phonet_stat evaluates to true and we try usb_remove_function() with its second parameter being f_phonet which is NULL and it causes NULL pointer dereference. This patch changes the initial values of (obex1|obex2|phonet)_stat to a nonzero value so that if the err_conf label is hit while the respective functions have not been acquired the usb_remove_function() is not called for those functions.

2013-12-17usb: gadget: add "maxpacket_limit" field to struct usb_epRobert Baldyga
This patch adds "maxpacket_limit" to struct usb_ep. This field contains maximum value of maxpacket supported by driver, and is set in driver probe. This value should be used by autoconfig() function, because value of field "maxpacket" is set to value from endpoint descriptor when endpoint becomes enabled. So when autoconfig() function will be called again for this endpoint, "maxpacket" value will contain wMaxPacketSize from descriptior instead of maximum packet size for this endpoint. For this reason this patch adds new field "maxpacket_limit" which contains value of maximum packet size (which defines maximum endpoint capabilities). This value is used in ep_matches() function used by autoconfig(). Value of "maxpacket_limit" should be set in UDC driver probe function, using usb_ep_set_maxpacket_limit() function, defined in gadget.h. This function set choosen value to both "maxpacket_limit" and "maxpacket" fields. This patch modifies UDC drivers by adding support for maxpacket_limit.

2013-12-12usb: gadget: FunctionFS: Remove VLAIS usage from gadget codeAndrzej Pietrasiewicz
The use of variable length arrays in structs (VLAIS) in the Linux Kernel code precludes the use of compilers which don't implement VLAIS (for instance the Clang compiler). This alternate patch calculates offsets into the kmalloc-ed memory buffer using macros. The previous patch required multiple kmalloc and kfree calls. This version uses "group" vs "struct" since it really is not a struct and is essentially a group of VLA in a common allocated block. This version also fixes the issues pointed out by Andrzej Pietrasiewicz and Michal Nazarewicz.

2013-12-12usb: gadget: configfs: allow setting function instance's nameAndrzej Pietrasiewicz
USB function's configfs config group is created in a generic way in usb/gadget/configfs.c:function_make(), which in turn delegates actual allocation and setup of the USB function instance to a particular implementation, e.g. in f_acm.c. The said implementation does its job in a parameter-less function e.g. acm_alloc_instance(), which results in creating an unnamed config group, whose name is set later in function_make(). function_make() creates the name by parsing a string of the form: <function name>.<instance name> which comes from userspace as a parameter to mkdir invocation. Up to now only <function name> has been used, while <instance name> has been ignored. This patch adds a set_inst_name() operation to struct usb_function_instance which allows passing the <instance name> from function_make() so that it is not ignored. It is entirely up to the implementor of set_inst_name() what to do with the <instance name>. In a typical case, the struct usb_function_instance is embedded in a larger struct which is retrieved in set_inst_name() with container_of(), and the larger struct contains a field to store the <instance name>.
