Date: Mon, 20 Sep 2021 18:42:53 +0200 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Sebastian Reichel <sebastian.reichel@...labora.com>, Sasha Levin <sashal@...nel.org> Subject: [PATCH 4.19 211/293] ARM: dts: imx53-ppd: Fix ACHC entry From: Sebastian Reichel <sebastian.reichel@...labora.com> [ Upstream commit cd7cd5b716d594e27a933c12f026d4f2426d7bf4 ] 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.
