2021-03-15ARM: dts: imx: bx50v3: Define GPIO line namesIan Ray1-0/+5
Define GPIO line names for b450v3, b650v3, and b850v3. Signed-off-by: Ian Ray <ian.ray@ge.com> Signed-off-by: Sebastian Reichel <sebastian.reichel@collabora.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
2020-09-22ARM: dts: imx6q: align GPIO hog names with dtschemaKrzysztof Kozlowski1-7/+7
dtschema for pca95xx expects GPIO hogs to end with 'hog' prefix. While touching the hogs, fix indentation (spaces -> tabs). Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
2020-05-20ARM: dts/imx6q-bx50v3: Set display interface clock parentsRobert Beckett1-7/+0
Avoid LDB and IPU DI clocks both using the same parent. LDB requires pasthrough clock to avoid breaking timing while IPU DI does not. Force IPU DI clocks to use IMX6QDL_CLK_PLL2_PFD0_352M as parent and LDB to use IMX6QDL_CLK_PLL5_VIDEO_DIV. This fixes an issue where attempting atomic modeset while using HDMI and display port at the same time causes LDB clock programming to destroy the programming of HDMI that was done during the same modeset.

2018-11-16ARM: dts: imx6q-bx50v3: user-space watchdog GPIO configurationIan Ray1-7/+0
Leave b{4,6}50v3 GPIO expander pca953x pins P05,P10,P11 unconfigured as they are now used to implement an additional watchdog mechanism in user space. P10,P11 pins remain unused (and therefore hogged) on b850v3. Signed-off-by: Ian Ray <ian.ray@ge.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
2018-01-23ARM: dts: imx6q-b450v3: Add switch port configurationSebastian Reichel1-0/+52
This adds support for the Marvell switch and names the network ports according to the labels, that can be found next to the connectors. The switch is connected to the host system using a PCI based network card. The PCI bus configuration has been written using the following information: root@b450v3# lspci -tv -[0000:00]---00.0-[01]----00.0 Intel Corporation I210 Gigabit Network Connection root@b450v3# lspci -nn 00:00.0 PCI bridge [0604]: Synopsys, Inc.

2017-03-07ARM: dts: imx6q-bx50v3: change pca953x GPIO default settingsKen Lin1-0/+7
Leave pca953x P06,P07 pins on b850v3 platform and P06 pin on b450v3/b650v3 unconfigured in the kernel space since they could be configured as DP1_RST and DP2_RST by the applications for the DP FW update support.

The license text has been mangled at some point then copy pasted across multiple files. Restore it to what it should be. Note that this is not intended as a license change.

2016-08-29ARM: dts: imx6q-bx50v3: configure unused pca953x pinsKen Lin1-0/+16
At power on, pca953x GPIO pins are configured as input and may cause unexpected interrupts. Configure the unused pins as GPO low to avoid unexpected interrupts.

2016-04-26ARM: dts: imx: b450/b650v3: Move ldb_di clk assignmentAkshay Bhat1-1/+4
Previously the LDB_DIx clocks could be specified in the ldb node. With the ERR009219 errata fix applied, the ldb_di clocks now needs to be specified in the clks node to ensure the clocks are setup early in the boot process.
