From 7d51b709262c5aa31d2b9cd31444112c1b2dae03 Mon Sep 17 00:00:00 2001 From: Abel Vesa Date: Wed, 24 Dec 2025 12:53:28 +0200 Subject: [PATCH] phy: qcom: edp: Make the number of clocks flexible On X Elite, the DP PHY needs another clock called ref, while all other platforms do not. The current X Elite devices supported upstream work fine without this clock, because the boot firmware leaves this clock enabled. But we should not rely on that. Also, even though this change breaks the ABI, it is needed in order to make the driver disables this clock along with the other ones, for a proper bring-down of the entire PHY. So in order to handle these clocks on different platforms, make the driver get all the clocks regardless of how many there are provided.
