From 8ab9eeef728ab62ff7f43efc4b9d835ef0a465b1 Mon Sep 17 00:00:00 2001 From: Gabor Juhos Date: Mon, 11 Mar 2024 19:45:19 +0100 Subject: clk: qcom: clk-alpha-pll: remove invalid Stromer register offset [ Upstream commit 4f2bc4acbb1916b8cd2ce4bb3ba7b1cd7cb705fa ] The offset of the CONFIG_CTL_U register defined for the Stromer PLL is wrong. It is not aligned on a 4 bytes boundary which might causes errors in regmap operations. Maybe the intention behind of using the 0xff value was to indicate that the register is not implemented in the PLL, but this is not verified anywhere in the code. Moreover, this value is not used even in other register offset arrays despite that those PLLs also have unimplemented registers. Additionally, on the Stromer PLLs the current code only touches the CONFIG_CTL_U register if the result of pll_has_64bit_config() is true which condition is not affected by the change. Due to the reasons above, simply remove the CONFIG_CTL_U entry from the Stromer specific array.
