This patch set contains a couple of fixes related to APM X-Gene SATA
controller driver.
v2 Change:
1. Drop the Link down retry patch from this patch set.
v4 Change:
1. Drop the patch to fix the csr-mask in dts for PHY clock
node of SATA Host Controller 1.
2. Add the patch to correct the OOB tunning parameters for
the COMINIT/COMWAKE parameters.
3. Add the patch to remove the NCQ support from the APM
X-Gene AHCI SATA Host controller driver.
4. Add the patch to remove the clock and PHY reference nodes
from the APM X-Gene Host controller dts node.
v5 Change :
1. All the patches are based on 3.16.0-rc6/for-3.17 kernel.
2. Drop the patch to remove the clock and PHY reference nodes
from the APM X-Gene Host controller dts node as it breaks
with old firmware.
3. Add the patch to skip phy and clock initialisation if
already done in the firmware.
4. Add the patch to fix the csr-mask in dts for PHY clock
node of SATA Host Controller 1.
5. Add the patch to remove the NCQ support from the APM
X-Gene AHCI SATA Host controller driver based on 3.16.0-rc6/
for-3.17 kernel.
6. Drop the patch to correct the OOB tunning parameters for
the COMINIT/COMWAKE parameters as it is already applied to
3.16/for-3.17 branch by the maintainer.
7. Drop the patch to fix the watermark threshold as it is
already applied to 3.16/for-3.17 branch by the maintainer.
v6 change :
1. Drop the patch to skip phy and clock initialisation if
already done in the firmware.
2. Drop the patch to fix the csr-mask in dts for PHY clock
node of SATA Host Controller 1.
3. Add the remove the clock and PHY node patch as it
fixes the dropped patches together. This patch works with
old and new firmware as well.
v7 change :
1. Drop the patch to remove the clock and PHY reference nodes
from the APM X-Gene Host controller dts node as it breaks
with old firmware if sata not initialised from the firmware.
2. Add the patch to skip phy and clock initialisation if
already done in the firmware.
3. Add the patch to fix the csr-mask in dts for PHY clock
node of SATA Host Controller 1.
4. Add the Link down retry patch with a proper comments and
explanation.
5. Drop the patch to remove NCQ as it is applied to 3.16/for-3.17.
v8 change :
1. Adding proper comments for link down retry patch.
2. changing the return type to bool for skip phy patch.
v9 change:
1. Fixing the code to match the comment for link down
retry patch.
