Subject: [RESEND PATCH v7 4/5] ARM: dts: am43xx-clocks: add spread spectrum support
Date: Sun,  6 Jun 2021 22:22:52 +0200	[thread overview]
Message-ID: <20210606202253.31649-5-dariobin@libero.it> (raw)
In-Reply-To: <20210606202253.31649-1-dariobin@libero.it>

Registers for adjusting the spread spectrum clocking (SSC) have been
added. As reported by the TI spruhl7x RM, SSC is supported only for LCD
and MPU PLLs, but the PRCM_CM_SSC_DELTAMSTEP_DPLL_XXX and
PRCM_CM_SSC_MODFREQDIV_DPLL_XXX registers, as well as the enable field
in the PRCM_CM_CLKMODE_DPLL_XXX registers are mapped for all PLLs (CORE,
MPU, DDR, PER, DISP, EXTDEV).

Signed-off-by: Dario Binacchi <dariobin@libero.it>
Acked-by: Tony Lindgren <tony@atomide.com>

Changes in v7:
- Add Tony Lindgren acked tag.
