Subject: [RFC PATCH v2 1/5] ARM: dts: imx28: reparent gpmi clock to ref_gpmi
Date: Mon, 17 Jan 2022 12:18:25 +0100 [thread overview]
Message-ID: <20220117111829.1811997-2-dario.binacchi@amarulasolutions.com> (raw)
In-Reply-To: <20220117111829.1811997-1-dario.binacchi@amarulasolutions.com>
Since ref_gpmi is sourced from pll0 (480MHz), It allows the GPMI
controller to manage High-Speed NAND Timing (edo mode 3,4 and 5).

Changes in v2:
- Reparent by device tree instead of code (drivers/clk/mxs/clk-imx28.c).
Suggested by Stephen Boyd.
