Subject: [PATCHv6 2/3] ARM: dts: imx53-ppd: Fix ACHC entry
Date: Mon, 12 Jul 2021 17:02:41 +0200 [thread overview]
Message-ID: <20210712150242.146545-3-sebastian.reichel@collabora.com> (raw)
In-Reply-To: <20210712150242.146545-1-sebastian.reichel@collabora.com>
PPD has only one ACHC device, which effectively is a Kinetis
microcontroller. It has one SPI interface used for normal
communication. Additionally it's possible to flash the device
firmware using NXP's EzPort protocol by correctly driving a
second chip select pin and the device reset pin.
