2018-03-12scsi: hisi_sas: dt-bindings: add an property of signal attenuationXiaofei Tan1-0/+7
For some new boards with hip07 chipset we are required to set PHY config registers differently. The hw property which determines how to set these registers is in the PHY signal attenuation readings. This patch add an devicetree property, "hisilicon,signal-attenuation", which is used to describe the signal attenuation of an board.

2017-09-05dt-bindings: Remove "status" from examplesRob Herring1-1/+0
Pretty much any node can have a status property, so it doesn't need to be in examples. Converted with the following command and removed examples with SoC and board specific splits: git grep -l -E 'status.*=.*' Documentation/devicetree/ | xargs sed -i -E '/\sstatus.*=.*"(disabled|ok|okay)/d' Acked-by: Mark Rutland <mark.rutland@arm.com> Signed-off-by: Rob Herring <robh@kernel.org>

2016-02-23devicetree: bindings: hisi_sas: add v2 HW bindingsJohn Garry1-1/+20
Add the dt bindings for HiSi SAS controller v2 HW. The main difference in the controller from dt perspective is interrupts. The v2 controller does not have dedicated fatal and broadcast interrupts - they are multiplexed on the channel interrupt. Each SAS v2 controller can issue upto 64 commands (or connection requests) on the system bus without waiting for a response - this is know as am-max-transmissions. In hip06, sas controller #1 has a limitation that it has to limit am-max-transmissions to 32 - this limitation is due to chip system bus design. It is not anticipated that any future chip incorporating v2 controller will have such a limitation.
