Subject: [PATCH v3 3/4] ARM: dts: am33xx-clocks: add spread spectrum support
Date: Mon, 29 Mar 2021 18:42:20 +0200 [thread overview]
Message-ID: <20210329164222.26794-4-dariobin@libero.it> (raw)
In-Reply-To: <20210329164222.26794-1-dariobin@libero.it>
Registers for adjusting the spread spectrum clocking (SSC) have been
added. As reported by the TI spruh73x RM, SSC is supported only for
LCD and MPU PLLs.
Signed-off-by: Dario Binacchi <dariobin@libero.it>
Acked-by: Tony Lindgren <tony@atomide.com>

Changes in v3:
- Add Tony Lindgren acked tag.
Changes in v2:
- Remove SSC registers from dpll_core_ck@490 node (SSC is not supported)
- Add SSC registers to dpll_mpu_ck@488 node.
