Subject: [PATCH 09/34] sunxi: clock: H6: unify PLL control bit definitions
Date: Sun, 23 Mar 2025 11:35:19 +0000	[thread overview]
Message-ID: <20250323113544.7933-10-andre.przywara@arm.com> (raw)
In-Reply-To: <20250323113544.7933-1-andre.przywara@arm.com>

The Allwinner PLLs share most of their control bits, they differ mostly
in the factors and dividers.

Drop the PLL specific definition of those common bits, and use one
shared macro, for all PLLs.

This requires changing the users in the SPL clock and DRAM code.
