Subject: [PATCH 5/7] clk: qcom: gcc-sc8180x: Add missing GDSC flags
Date: Sun,  8 Mar 2026 22:00:27 -0300	[thread overview]
Message-ID: <20260309010214.224621-6-val@packett.cool> (raw)
In-Reply-To: <20260309010214.224621-1-val@packett.cool>

Similarly to sc8280xp, the GCC GDSCs can and should use the retain
registers so as not to lose their state when entering lower power modes.

Fixes: 4433594bbe5d ("clk: qcom: gcc: Add global clock controller driver for SC8180x")
Signed-off-by: Val Packett <val@packett.cool>
