From 44e5d08812805bcb0f37e18f6c4eab1174a9d053 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Wed, 11 Aug 2021 17:49:00 +0200 Subject: ravb: Remove checks for unsupported internal delay modes MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The EtherAVB instances on the R-Car E3/D3 and RZ/G2E SoCs do not support TX clock internal delay modes, and the EtherAVB driver prints a warning if an unsupported "rgmii-*id" PHY mode is specified, to catch buggy DTBs. Commit a6f51f2efa742df0 ("ravb: Add support for explicit internal clock delay configuration") deprecated deriving the internal delay mode from the PHY mode, in favor of explicit configuration using the now mandatory "rx-internal-delay-ps" and "tx-internal-delay-ps" properties, thus delegating the warning to the legacy fallback code. Since explicit configuration of a (valid) internal clock delay configuration is enforced by validating device tree source files against DT binding files, and all upstream DTS files have been converted as of commit a5200e63af57d05e ("arm64: dts: renesas: rzg2: Convert EtherAVB to explicit delay handling"), the checks in the legacy fallback code can be removed.
