Subject: [PATCH v2 4/4] ARM: dts: qcom: Add Samsung Galaxy Express support
Date: Sat, 27 May 2023 20:10:09 -0400 [thread overview]
Message-ID: <20230528001010.47868-5-guptarud@gmail.com> (raw)
In-Reply-To: <20230527040905.stmnoshkdqgiaex6@ripper>
This adds a very basic device tree file for the Samsung Galaxy Express
SGH-I437. Currently, the following things work: UART, eMMC, SD Card, and
USB.
