Patches are generated using the "format-patch" command from the following location: *https://www.codeaurora.org/cgit/quic/kernel/galak-msm/log/?h=apq_ipq_base *rev=0771849495b4128cac2faf7d49c85c729fc48b20 Patches numbered 76/77/102/103 have already been integrated in 3.14.12, so they're not in this list. All these patches are either integrated are pending integration into kernel.org, therefore these patches should go away once the kernel gets upgraded to 3.16. Support is currently limited to AP148 board but can be extended to other platforms in the future. These changes do not cover ethernet connectivity.

Subject: [PATCH 025/182] pinctrl: msm: drop wake_irqs bitmap
|
|
|
|
Currently, the wake_irqs bitmap is used to track whether there are any
|
|
gpio's which are configured as wake irqs, and uses this to determine
|
|
whether or not to call enable_irq_wake()/disable_irq_wake() on the
|
|
summary interrupt.
|
|
|
|
However, the genirq core already handles this case, by maintaining a
|
|
'wake_count' per irq_desc, and only calling into the controlling
|
|
irq_chip when wake_count transitions 0 <-> 1.
|
|
|
|
Drop this bitmap, and unconditionally call irq_set_irq_wake() on the
|
|
summary interrupt.
