[PATCHv12 0/9] OMAP3+: PRCM chain handler

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

This is a repost of Tero's PRCM chain handler patch set with a few changes:

- A new mux patch has been added to place hwmod mux entries with
  OMAP_DEVICE_PAD_WAKEUP set into the dynamic list

- Several OCP barriers have been added to PRM writes to try to protect
  against races between PRM register writes and the MPU

- Kerneldoc documentation has been added

- The pending IRQ test functions have been split into per-SoC versions

- Some patches have been rearranged and merged to avoid churn

- The PRM IRQ handler is now installed on OMAP4

This updated series has been tested on OMAP3530 BeagleBoard in dynamic idle
with off-mode enabled, although the functions that do dynamic IRQ mapping
have not been tested.

I've preserved Signed-off-by:s and other tags, even though the patches
have been rearranged.  Any further testing would be appreciated, and if any
Signed-off-by: or other tag does not belong, please advise and I'll remove it.
I'd like to send Tony a pull request for this tomorrow.

Original series description follows:

From: Tero Kristo <t-kristo@xxxxxx>

PRCM chain handler is adding a support to the omap3+ kernel that
allows different drivers to use PRCM interrupt events for their
own purposes, typically this means IO wakeups. This work was
attempted to integrate as its own driver at some point of
the evolution of this set, however this was now postponed as
the lacking support is basically blocking a few drivers.
