Hi,
The patchset is based on David Miller's "net-next" repo.
The patchset extends the Broadcom iProc mdio mux to add support for
suspend/resume and the ability to configure the internal clock
divider. The patchset also sets the scan control register to
disable external master access.
The base address of the mdio-mux-bcm-iproc is modified to point to the
start of the mdio block's address space, to be able to access all the
mdio's registers. The missing registers are required to configure the
internal clock divider registers in some of the Broadcom SoC's.
Changes from v3:
- Removed 'platform_set_drvdata(pdev, NULL)' call (in patch 5/8)
- Fixed the return code handling for the devm_clk_get() call (in patch
7/8)
- Added Reviewed-by tag to Patch 8/8
Changes from v2:
- Addressed Andrew's comments:
- Moved to using devm_mdiobus_alloc. Added this as a separate patch.
- Changed to reverse christmas tree order for variable declaration in
the clock patch
- Addressed Florian's comments:
- Removed null checks for the clock before calling unprepare in
both clock and pm patches.
- Added check for EPROBE_DEFER when fetching the clock in the clock
patch.
- The patch to use the devm API has been added before the clock & pm
patches. This patch is now patch '5' in the series.
- Added reviewed-by tags to commit messages of patches which remain
unmodified from v2.
- Modified PM patch to use platform_get_drvdata() in suspend/resume
API's, similar to the recent fix that went in for the remove()
api.
Changes from v1:
- Addressed Andrew's comments.
- Reworked the patches to be based on 'net-next'
- Removed 'fixes' from the commit messages, the changes are related
to the new features being added.
- Maintained backward compatibility to older dt-blob's specifying
base addresse with an offset. The correction is applied in the
driver and a message is printed to update the dt-blob.
- Re-worked and re-ordered the last four patches (4-7).
- Added setting of the scan control register as a new patch
- Added a call to 'clk_prepare_enable()' in the patch that adds
the clock config support, removed the debug message when clock
is not passed.
- Simplified the pm support patch (removed the array used for the
save/restore logic).
Thanks
