From 1ebaa5e189151a396de3fcd280078eaf7b922920 Mon Sep 17 00:00:00 2001 From: Daniel Machon Date: Thu, 24 Oct 2024 00:01:20 +0200 Subject: [PATCH 01/15] net: sparx5: add support for lan969x targets and core clock In preparation for lan969x, add lan969x targets to sparx5_target_chiptype and set the core clock frequency for these throughout. Lan969x only supports a core clock frequency of 328MHz. Also, set the policer update internal (pol_upd_int) matching the 328 MHz frequency of the lan969x targets.

Add new Kconfig symbol CONFIG_LAN969X_CONFIG for compiling the lan969x driver. It has been decided to give lan969x its own Kconfig symbol, as a considerable amount of code is needed, beside the Sparx5 code, to add full chip support (and more will be added in future series). Also this makes it possible to compile Sparx5 without lan969x.

69b614251784fb0c2baf8729c041326a5bb42720 Mon Sep 17 00:00:00 2001 From: Daniel Machon Date: Thu, 24 Oct 2024 00:01:26 +0200 Subject: [PATCH 07/15] net: lan969x: add register diffs to match data Add new file lan969x_regs.c that defines all the register differences for lan969x, and add it to the lan969x match data. GW_DEV2G5_PHASE_DETECTOR_CTRL, FP_DEV2G5_PHAD_CTRL_PHAD_ENA and FP_DEV2G5_PHAD_CTRL_PHAD_FAILED are required by the new register macros which was introduced earlier. Add these for Sparx5 also.

In order to accommodate for this in the future, we need to give lan969x it's own function for calculating the DSM calendar. The function calculates the calendar for each taxi bus. The calendar is used for bandwidth allocation towards the ports attached to the taxi bus. A calendar configuration consists of up-to 64 slots, which may be allocated to ports or left unused. Each slot accounts for 1 clock cycle. Also expose sparx5_cal_speed_to_value(), sparx5_get_port_cal_speed, sparx5_cal_bw and SPX5_DSM_CAL_EMPTY for use by lan969x.
