From 9296f9a8d7ffc96b8a8220a0e74c7dacb1934b2e Mon Sep 17 00:00:00 2001 From: Jonas Karlman Date: Fri, 4 Aug 2023 09:34:00 +0000 Subject: [PATCH] clk: rockchip: rk3568: Add dummy support for GMAC speed clocks Pine64 Quartz64 boards DT reference SCLK_GMAC1_RGMII_SPEED in the assigned-clocks property of the gmac1 node. This result in a ENOENT error when driver core tries to set a parent for this clock. The clock speed in rgmii/rmii mode is changed using clk_set_rate of the tx_rx clock and not using clk_set_parent of the speed clock. Add dummy support for SCLK_GMAC1_RGMII_SPEED and similar clocks to clk driver to allow a driver for gmac node to probe.
