Subject: [PATCH v2 1/1] clk: tegra: support 48MHz clock for pll_p_out1
Date: Mon, 27 Apr 2026 16:24:47 +0300 [thread overview]
Message-ID: <20260427132447.118272-2-clamor95@gmail.com> (raw)
In-Reply-To: <20260427132447.118272-1-clamor95@gmail.com>
From: Dmitry Osipenko <digetx@gmail.com>
UEFI on Surface2 sets pll_p_out1 to 48MHz which is not supported by kernel
and causes BUG() early on. Add 48MHz clock support for pll_p_out1.
