From 3e632d9c33d8a4f0d8f98e69b56bd2f2145d91c4 Mon Sep 17 00:00:00 2001 From: Gabor Juhos Date: Mon, 28 Oct 2024 19:48:15 +0100 Subject: [PATCH] clk: qcom: apss-ipq-pll: drop 'alpha_en_mask' from IPQ5018 PLL config Since neither 'alpha' nor 'alpha_hi' is defined in the configuration, those will be initialized with zero values implicitly. By using zero alpha values, the output rate of the PLL will be the same whether alpha mode is enabled or not. Remove the superfluous initialization of the 'alpha_en_mask' member to make it clear that enabling alpha mode is not required to get the desired output rate. Despite that enabling alpha mode is not needed for the initial configuration, the set_rate() op might require that it is enabled already. In this particular case however, the clk_alpha_pll_stromer_set_rate() function will get reset the ALPHA_EN bit when the PLL's rate changes, so dropping 'alpha_en_mask' is safe. No functional changes, the initial rate of the PLL is the same both before and after the patch. Tested on TP-Link Archer AX55 v1 (IPQ5018).
