Subject: [PATCH v2 1/5] ARM: dts: s5pv210: Remove spi-cs-high on panel in Aries
Date: Sun, 27 Mar 2022 11:08:50 -0700 [thread overview]
Message-ID: <CY4PR04MB05670C771062570E911AF3B4CB1C9@CY4PR04MB0567.namprd04.prod.outlook.com> (raw)
In-Reply-To: <CY4PR04MB05677B4C4E26A8A179F6ABC0CB179@CY4PR04MB0567.namprd04.prod.outlook.com>
Since commit 766c6b63aa04 ("spi: fix client driver breakages when using
GPIO descriptors"), the panel has been blank due to an inverted CS GPIO.
In order to correct this, drop the spi-cs-high from the panel SPI device.
Fixes: 766c6b63aa04 ("spi: fix client driver breakages when using GPIO descriptors")
