From c31d1cdd7bff1d2c13d435bb9d0c76bfaa332097 Mon Sep 17 00:00:00 2001 From: Lorenzo Bianconi Date: Tue, 12 Nov 2024 01:08:49 +0100 Subject: [PATCH 1/6] clk: en7523: remove REG_PCIE*_{MEM,MEM_MASK} configuration REG_PCIE*_MEM and REG_PCIE*_MEM_MASK regs (PBUS_CSR memory region) are not part of the scu block on the EN7581 SoC and they are used to select the PCIE ports on the PBUS, so remove this configuration from the clock driver and set these registers in the PCIE host driver instead. This patch does not introduce any backward incompatibility since the dts for EN7581 SoC is not upstream yet.
