Subject: [PATCH v2 01/15] clk: sunxi-ng: mp: Add SUNXI_CCU_P_DATA_WITH_MUX_GATE wrapper
Date: Fri, 14 Feb 2025 12:53:45 +0000 [thread overview]
Message-ID: <20250214125359.5204-2-andre.przywara@arm.com> (raw)
In-Reply-To: <20250214125359.5204-1-andre.przywara@arm.com>
The PRCM CCU in the A523 SoC contains some clocks that only feature a
P (shift) factor, but no M divider.
Treat this as a special case of an MP clock: by forcing the M mask to be
0 bits wide, this always result in the M divider value to be 1.
