As musb_advance_schedule() is now the only remaning caller of musb_giveback() (and the only valid context of such call), just fold the latter into the former and then rename __musb_giveback() into musb_giveback(). This is a net minor shrink. Signed-off-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

The argument for the 'is_in' parameter of musb_cleanup_urb() is always extracted from an URB that's passed to the function. So that parameter is superfluous; remove it.

The existance of the scheduling list shouldn't matter in determining whether there's currectly an URB executing on a hardware endpoint. What should actually matter is the 'in_qh' or 'out_qh' fields of the 'struct musb_hw_ep' -- those are set in musb_start_urb() and cleared in musb_giveback() when the endpoint's URB list drains. Hence we should be able to replace the big *switch* statements in musb_urb_dequeue() and musb_h_disable() with mere musb_ep_get_qh() calls... While at it, do some more changes: - add 'is_in' variable to musb_urb_dequeue(); - remove the unnecessary 'epnum' variable from musb_h_disable(); - fix the comment style in the vicinity. This is a minor shrink of source and object code.

Factor out the often used code to get/set the active 'qh' pointer for the hardware endpoint. Change the way the case of a shared FIFO is handled by setting *both* 'in_qh' and 'out_qh' fields of 'struct musb_hw_ep'. That seems more consistent and makes getting to the current 'qh' easy when the code knows the direction beforehand. While at it, turn some assignments into intializers and fix declaration style in the vicinity.

Refactor musb_save_toggle() as follows: - replace 'struct musb_hw_ep *ep' parameter by 'struct musb_qh *qh' to avoid re-calculating this value - move usb_settogle() call out of the *if* operator.

Suppress "parasitic" endpoint interrupts in the DMA mode when using CPPI DMA driver; they're caused by the MUSB gadget driver using the DMA request mode 0 instead of the mode 1.

Sergei Shtylyov authored
The gadget EP0 code routinely ignores an interrupt at end of the data phase because of musb_g_ep0_giveback() resetting the state machine to "idle, waiting for SETUP" phase prematurely. The driver also prematurely leaves the status phase on receiving the SetupEnd interrupt. As there were still unhandled endpoint 0 interrupts happening from time to time after fixing these issues, there turned to be yet another culprit: two distinct gadget states collapsed into one. The (missing) state that comes after STATUS IN/OUT states was typically indiscernible from them since the corresponding interrupts tend to happen within too little period of time (due to only a zero-length status packet in between) and so they got coalesced; yet this state is not the same as the next one which is associated with the reception of a SETUP packet. Adding this extra state seems to have fixed the rest of the unhandled interrupts that generic_interrupt() and davinci_interrupt() hid by faking their result and only emitting a debug message -- so, stop doing that.

The V3 regulator can be configured with an external resistor connected to the feedback pin (R24 in the data sheet) to increase the voltage range. For example, hx4700 has R24 = 3.32 kOhm to achieve a maximum V3 voltage of 1.55 V which is needed for 624 MHz CPU frequency.

In the near future, the driver core is going to not allow direct access to the driver_data pointer in struct device. Instead, the functions dev_get_drvdata() and dev_set_drvdata() should be used. These functions have been around since the beginning, so are backwards compatible with all older kernel versions.

Regulators need to be available early in init in order to allow them to be available for consumers when requested.

The Maxim 1586 regulator is a voltage regulator with 2 voltage outputs, specially suitable for Marvell PXA chips. One output is in the range of required VCC_CORE by the PXA27x chips, the other in the VCC_USIM required as well by PXA27x chips. The chip is controlled through the I2C bus.

While doing trie_rebalance(): resize(), inflate(), halve() RCU free tnodes before updating their parents. It depends on RCU delaying the real destruction, but if RCU readers start after call_rcu() and before parent update they could access freed memory. It is currently prevented with preempt_disable() on the update side, but it's not safe, except maybe classic RCU, plus it conflicts with memory allocations with GFP_KERNEL flag used from these functions. This patch explicitly delays freeing of tnodes by adding them to the list, which is flushed after the update is finished.

On systems where CONFIG_SHMEM is disabled, mounting tmpfs filesystems can fail when tmpfs options are used. This is because tmpfs creates a small wrapper around ramfs which rejects unknown options, and ramfs itself only supports a tiny subset of what tmpfs supports. This makes it pretty hard to use the same userspace systems across different configuration systems. As such, ramfs should ignore the tmpfs options when tmpfs is merely a wrapper around ramfs. This used to work before commit c3b1b1cb as previously, ramfs would ignore all options. But now, we get: ramfs: bad mount option: size=10M mount: mounting mdev on /dev failed: Invalid argument Another option might be to restore the previous behavior, where ramfs simply ignored all unknown mount options ... which is what Hugh prefers.
