From f65d7c05431901e108742e0bbdb1718c7c26eace Mon Sep 17 00:00:00 2001 From: Sheetal Tigadoli Date: Tue, 11 Feb 2025 15:37:52 +0000 Subject: [PATCH] Documentation:bindings:nvpps:Deprecate ptp_tsc_k_int property Deprecate ptp_tsc_k_int property from nvpps. The k_int parameter is calculated by the driver itself Bug 4899241 Signed-off-by: Sheetal Tigadoli Change-Id: I8e492bf6748f94fbe0136c2a1a909d8ba5031aea Reviewed-on: https://git-master.nvidia.com/r/c/linux-nv-oot/+/3300419 Reviewed-by: Kiran Kumar Bobbu GVS: buildbot_gerritrpt Reviewed-by: Sumeet Gupta --- Documentation/devicetree/bindings/nvpps/nvpps.txt | 7 ------- 1 file changed, 7 deletions(-) diff --git a/Documentation/devicetree/bindings/nvpps/nvpps.txt b/Documentation/devicetree/bindings/nvpps/nvpps.txt index 87be217b..0f5f6622 100644 --- a/Documentation/devicetree/bindings/nvpps/nvpps.txt +++ b/Documentation/devicetree/bindings/nvpps/nvpps.txt @@ -23,12 +23,6 @@ Optional properties: - memmap_phc_regs: boolean flag to indicate MAC PHC regs to be memory mapped for getting PTP time.
