Subject: [PATCH v2 4/8] clk: loongson2: Allow zero divisors for dividers
Date: Tue, 17 Jun 2025 16:24:22 +0000 [thread overview]
Message-ID: <20250617162426.12629-5-ziyao@disroot.org> (raw)
In-Reply-To: <20250617162426.12629-1-ziyao@disroot.org>
Loongson 2K0300 and 2K0500 ship divider clocks which allows zero
divisors, in which case the divider acts the same as one is specified.
Let's pass CLK_DIVIDER_ALLOW_ZERO when registering divider clocks to
prepare for future introduction of these clocks.
