Subject: [PATCH 3/5] clk: rockchip: rk3568: Add PLL rate for 115.2MHz
Date: Wed, 18 Oct 2023 11:18:46 -0500 [thread overview]
Message-ID: <20231018161848.346947-4-macroalpha82@gmail.com> (raw)
In-Reply-To: <20231018161848.346947-1-macroalpha82@gmail.com>
From: Chris Morgan <macromorgan@hotmail.com>
Add support for a PLL rate of 115.2MHz so that the Powkiddy RK2023 panel
can run at a requested 60hz (59.99, close enough).
I have confirmed this rate fits with all the constraints
listed in the TRM for the VPLL (as an integer PLL) in Part 1 "Chapter
2 Clock & Reset Unit (CRU)."
