From f6abcc21d94393801937aed808b8f055ffec8579 Mon Sep 17 00:00:00 2001 From: Shazad Hussain Date: Tue, 15 Nov 2022 20:59:56 +0530 Subject: [PATCH] clk: qcom: gcc-sc8280xp: add cxo as parent for three ufs ref clks The three UFS reference clocks, gcc_ufs_ref_clkref_clk for external UFS devices, gcc_ufs_card_clkref_clk and gcc_ufs_1_card_clkref_clk for two PHYs are all sourced from CXO. Added parent_data for all three reference clocks described above to reflect that all three clocks are sourced from CXO to have valid frequency for the ref clock needed by UFS controller driver.
