From c41f66ea9dae235cc1a5c3108a4420483d730328 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Tue, 5 May 2026 17:29:09 +0200 Subject: [PATCH] clk: qcom: dispcc-x1e80100: Fix (possibly) dumping regmap Reading few registers at the end of the block (e.g. 0x10000, 0x10004) might result in synchronous external abort, so limit the regmap to the last readable register which allows dumping the regs for debugging.
