Re: USB Ethernet gadget on Nokia n900
Hi! My N900 can boot kernel from v3.12-rc5-n900 branch compiled with arch/arm/configs/rx51_defconfig. Also it can boot full Maemo5 system (with CSSU and some minor system changes) and usb network via g_nokia.ko gadget working fine... So if it does not working for you then kernel usb subsystem could have problems with using gadgets directly from zimage. After some hand-bisecting and real-bisecting, I found two commits that cause problems for 3.13: With these reverted, I get usb networking back in 3.13 on nokia n900. (Pali, if you revert these, you should get working usb networking in your 3.13 branch, too.) Any ideas?

The usb_phy_set_resume and usb_phy_set_suspend is replaced with power_on and power_off to align with the new PHY framework. musb-xceiv can't be removed as of now because musb core uses xceiv.state and xceiv.otg. Once there is a separate state machine to handle otg, these can be moved out of xceiv and then we can start using the generic PHY framework.

[PATCH v4 0/8] Per-user clock constraints
Hello, this fourth version of the series is mainly intended to address many good comments from Stephen Boyd, most notably: * Make sure that best_parent_p is populated with the current parent before calling clk_ops.determine_rate() * Make sure we don't lose information about the caller in of_clk_get_* * Refresh the effective rate after a per-user clk is removed * Store requested rate and re-apply it when constraints are updated The first six patches are just cleanups that should be desirable on their own, and that should make easier to review the actual per-user clock patch. The seventh patch actually moves the per-clock data that was stored in struct clk to a new struct clk_core and adds references to it from both struct clk and struct clk_hw. struct clk is now ready to contain information that is specific to a given clk consumer. The eighth patch adds API for setting floor and ceiling constraints and stores that information on the per-user struct clk, which is iterable from struct clk_core. They are based on top of 3.18-rc1. http://cgit.collabora.com/git/user/tomeu/linux.git/log/?h=per-user-clk-constraints-v4 Thanks, Tomeu Tomeu Vizoso (8): MIPS: Alchemy: Remove direct access to prepare_count field of struct clk clk: Remove unused function __clk_get_prepare_count clk: Don't try to use a struct clk* after it could have been freed clk: Don't expose __clk_get_accuracy clk: change clk_debugfs_add_file to take a struct clk_hw clk: Change clk_ops-determine_rate to return a clk_hw as the best parent clk: Make clk API return per-user struct clk instances clk: Add floor and ceiling constraints to clock rates Documentation/clk.txt | 2 +- arch/arm/mach-omap2/cclock3xxx_data.c | 108 +++-- arch/arm/mach-omap2/clock.h | 11 +- arch/arm/mach-omap2/clock_common_data.c | 5 +- arch/mips/alchemy/common/clock.c| 17 +- drivers/clk/at91/clk-programmable.c | 4 +- drivers/clk/bcm/clk-kona.c | 4 +- drivers/clk/clk-composite.c | 9 +- drivers/clk/clk.c | 788 +--- drivers/clk/clk.h | 5 + drivers/clk/clkdev.c| 73 ++- drivers/clk/hisilicon/clk-hi3620.c | 2 +- drivers/clk/qcom/clk-rcg.c | 20 +- drivers/clk/qcom/clk-rcg2.c | 28 +- drivers/clk/sunxi/clk-factors.c | 4 +- drivers/clk/sunxi/clk-sun6i-ar100.c | 4 +- include/linux/clk-private.h | 41 +- include/linux/clk-provider.h| 17 +- include/linux/clk.h | 18 + 19 files changed, 771 insertions(+), 389 deletions(-) -- 1.9.3 -- To unsubscribe from this list: send the line unsubscribe linux-omap in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
[PATCH v4 7/8] clk: Make clk API return per-user struct clk instances
Moves clock state to struct clk_core, but takes care to change as little API as
possible.
struct clk_hw still has a pointer to a struct clk, which is the
implementation's per-user clk instance, for backwards compatibility.
The struct clk that clk_get_parent() returns isn't owned by the caller, but by
the clock implementation, so the former shouldn't call clk_put() on it.
Because some boards in mach-omap2 still register clocks statically, their clock
registration had to be updated to take into account that the clock information
is stored in struct clk_core now.
Signed-off-by: Tomeu Vizoso tomeu.viz...@collabora.com
---
v4: * Remove unused function __clk_core_to_clk
* Use core more often as the name for struct clk_core* variables
* Make sure we don't lose information about the caller in of_clk_get_*
v3: * Rebase on top of linux-next 20141009
v2: * Remove exported functions that aren't really used outside clk.c
* Rename new internal functions to clk_core_ prefix
* Remove redundant checks for error pointers in *_get_parent
* Change __clk_create_clk to take a struct clk_hw instead
* Match the original error behavior in clk_get_sys

Well it works with omap2plus_defconfig long as serial port timeouts are configured, no USB cable is connected and and the screen is blanked. When it works, both keyboard debug LEDs will go off during idle, which really should be most of the time if you plan to use it as a phone. The left debug LED goes off for retention idle, when both go off it's hitting off-idle.

[PATCH v2 35/47] arm: Register with kernel poweroff handler
Register with kernel poweroff handler instead of setting pm_power_off
directly. Always use register_power_off_handler_simple as there is no
indication that more than one poweroff handler is registered.
If the poweroff handler only resets the system or puts the CPU in sleep mode,
select the fallback priority to indicate that the poweroff handler is one
of last resort. If the poweroff handler powers off the system, select the
default priority.

- Use defines to specify poweroff handler priorities
- Drop changes in arch/arm/mach-at91/setup.c (file removed upstream)
