Subject: [PATCH v6 0/3] Add QCOM SNPS PHY overriding params support
Date: Thu, 19 May 2022 09:58:06 +0530 [thread overview]
Message-ID: <1652934489-23386-1-git-send-email-quic_kriskura@quicinc.com> (raw)
changes in v6:
Fixed errors in dt-bindings.
Fixed nitpick in driver code.
changes in v5:
Fixed nitpicks in code.
Added minimum and maximum for each parameter added in dt-bindings.
Added proper suffixes to each parameter as per dtschema.
changes in v4:
Fixed nitpicks in code.
Initial compliance test results showed overshoot in the middle of eye
diagram. The current dt values were put in place to correct it and fix
overshoot issue.
changes in v3:
Added support for phy tuning parameters to be represented in bps and
corresponding register values to be written are obtained by traversing
through data map declared in the driver.
changes in v2:
Reading the individual fields in each overriding register from
device tree.
