From 4d212debc7a646ffa61cca767e18d882daadb51d Mon Sep 17 00:00:00 2001 From: Roy Lee Date: Wed, 29 May 2019 13:44:32 +0800 Subject: [PATCH] [device][platform] add platform as5812-54x, accton. (#2889) * Add new device accton_as5812_54x. Signed-off-by: roy_lee * Rename 5812's config.bcm. Signed-off-by: roy_lee * Change fan module to support lm-sensors. Validate for thermal policy. Signed-off-by: roy_lee * Add bask reset and lpmode control of 6 QSFP ports. Signed-off-by: roy_lee * Get currect duty of fan for comparing. Instead of by stored duty from previous iteration. Signed-off-by: roy_lee * Roll back the mistakes to update mellanox submodules. Signed-off-by: roy_lee * Rollback for misoperation on submodule platform/p4/SAI-P4-BM. Signed-off-by: roy_lee * Change indexes of ports to start from 1, as them on the front panel. Add low-power mode control of the transciever's eeprom, follows SFF-8436.
