The m32r architecture was the only user of the old-style
rtc driver for ds1302. The architecture is getting removed
now, and we have a modern driver for the same hardware in
drivers/rtc/rtc-ds1302.c, so this one won't be missed.

This is a requirement which has always existed but, somehow, wasn't
reflected in the documentation and problems weren't found until now
when Tuba Yavuz found a possible deadlock happening between dwc3 and
f_hid. She described the situation as follows:
spin_lock_irqsave(&hidg->write_spinlock, flags); // first acquire
/* we our function has been disabled by host */
if (!hidg->req) {
free_ep_req(hidg->in_ep, hidg->req);
goto try_again;
}
[...]
status = usb_ep_queue(hidg->in_ep, hidg->req, GFP_ATOMIC);
=>
[...]
=> usb_gadget_giveback_request
=>
f_hidg_req_complete
=>
spin_lock_irqsave(&hidg->write_spinlock, flags); // second acquire
Note that this happens because dwc3 would call ->complete() on a
failed usb_ep_queue() due to failed Start Transfer command. This is,
anyway, a theoretical situation because dwc3 currently uses "No
Response Update Transfer" command for Bulk and Interrupt endpoints.
It's still good to make this case impossible to happen even if the "No
Reponse Update Transfer" command is changed.

The options USB_EHCI_ATH79 and USB_OHCI_ATH79 only enable the
generic EHCI and OHCI platform drivers, and have been marked as
deprecated since 2012.
These can be safely removed if we make sure that USB_EHCI_ROOT_HUB_TT
still get enabled for the EHCI driver. This is now done be selecting
this option when the EHCI platform driver is enabled on the ATH79
platform.

It looks like there is a possibility of a double-free vulnerability on an
error path of the f_midi_set_alt function in the f_midi driver. If the
path is feasible then free_ep_req gets called twice:
req->complete = f_midi_complete;
err = usb_ep_queue(midi->out_ep, req, GFP_ATOMIC);
=> ...
usb_gadget_giveback_request
=>
f_midi_complete (CALLBACK)
(inside f_midi_complete, for various cases of status)
free_ep_req(ep, req); // first kfree
if (err) {
ERROR(midi, "%s: couldn't enqueue request: %d\n",
midi->out_ep->name, err);
free_ep_req(midi->out_ep, req); // second kfree
return err;
}
The double-free possibility was introduced with commit ad0d1a058eac
("usb: gadget: f_midi: fix leak on failed to enqueue out requests").
Found by MOXCAFE tool.

In certain cases interrupt enablement will be delayed relative to when
the InterruptEnable bits are written. One example of this is when
a GPIO's "debounce" logice is first enabled. After enabling debounce,
there is a 900 us "warm up" period during which InterruptEnable[0]
(bit 11) will read as 0 despite being written 1. During this time
InterruptSts will not be updated, nor will interrupts be delivered, even
if the GPIO's interrupt configuration has been written to the register.
To work around this delay, poll the InterruptEnable bits after setting
them to ensure interrupts have truly been enabled in hardware before
returning from the irq_enable handler.

For generic pins, parameter "arg" is 0 or 1.
For special pins, bias-disable is set by R0R1,
so we need transmited "00" to set bias-disable
When we set "bias-disable" as high-z property,
the parameter should be "MTK_PUPD_SET_R1R0_00".

(This can happen when EEPROM is not populated or configured incorrectly)
Root-Cause:
When EEE is enabled, the mac config register ASD is not set

Fix:
