From f06a3ad737c6652f3f18a9357c842f9ec05a7842 Mon Sep 17 00:00:00 2001 From: schobtr Date: Sun, 9 May 2021 23:03:12 +0700 Subject: [PATCH] [Haliburton-Celestica] Use psu driver dps200 from Linux kernel (#7247) Why I did it Fix issues below. #7133 #6602 So, remove the dps200 driver from the platform-specific driver. Then, add the dps200 module driver to the Linux kernel tree. How I did it Remove the dps200 driver from the platform-specific driver and add the dps200 module driver to the Linux kernel. How to verify it Build an image with Azure/sonic-linux-kernel#207 Then, install to the Haliburton. --- .../haliburton/modules/Makefile | 2 +- .../haliburton/modules/dps200.c | 128 ------ .../haliburton/modules/pmbus.h | 425 ------------------ 3 files changed, 1 insertion(+), 554 deletions(-) delete mode 100644 platform/broadcom/sonic-platform-modules-cel/haliburton/modules/dps200.c delete mode 100644 platform/broadcom/sonic-platform-modules-cel/haliburton/modules/pmbus.h diff --git a/platform/broadcom/sonic-platform-modules-cel/haliburton/modules/Makefile b/platform/broadcom/sonic-platform-modules-cel/haliburton/modules/Makefile index 415d1b5e62f0..b34cf2cabe20 100644 --- a/platform/broadcom/sonic-platform-modules-cel/haliburton/modules/Makefile +++ b/platform/broadcom/sonic-platform-modules-cel/haliburton/modules/Makefile @@ -1 +1 @@ -obj-m := mc24lc64t.o emc2305.o smc.o hlx_gpio_ich.o dps200.o +obj-m := mc24lc64t.o emc2305.o smc.o hlx_gpio_ich.o diff --git a/platform/broadcom/sonic-platform-modules-cel/haliburton/modules/dps200.c b/platform/broadcom/sonic-platform-modules-cel/haliburton/modules/dps200.c deleted file mode 100644 index 6279ca70decf..000000000000 --- a/platform/broadcom/sonic-platform-modules-cel/haliburton/modules/dps200.c +++ /dev/null @@ -1,128 +0,0 @@ -/* - * Hardware monitoring driver for Delta DPS200 - * - * (C) Copyright 2019, Celestica Inc. - * Author: Pradchaya Phucharoen - * - * This program is free software; you can redistribute it and/or modify - * it under the terms of the GNU General Public License as published by - * the Free Software Foundation; either version 2 of the License, or - * (at your option) any later version. - * - * This program is distributed in the hope that it will be useful, - * but WITHOUT ANY WARRANTY; without even the implied warranty of - * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
