ARM: dts: Move .dts files to vendor sub-directories

2023-06-21T17:39:50+00:00

The arm dts directory has grown to 1559 boards which makes it a bit unwieldy to maintain and use. Past attempts stalled out due to plans to move .dts files out of the kernel tree. Doing that is no longer planned (any time soon at least), so let's go ahead and group .dts files by vendors. This move aligns arm with arm64 .dts file structure. There's no change to dtbs_install as the flat structure is maintained on install. The naming of vendor directories is roughly in this order of preference: - Matching original and current SoC vendor prefix/name (e.g. ti, qcom) - Current vendor prefix/name if still actively sold (SoCs which have been aquired) (e.g. nxp/imx) - Existing platform name for older platforms not sold/maintained by any company (e.g. gemini, nspire) The whole move was scripted with the exception of MAINTAINERS and a few makefile fixups.

ARM: dts: Unify pinctrl-single pin group nodes for omap3

2023-05-23T07:59:19+00:00

We want to unify the pinctrl-single pin group nodes to use naming "pins". Otherwise non-standad pin group names will add make dtbs checks errors when the pinctrl-single yaml binding gets merged. Cc: Conor Dooley Cc: Krzysztof Kozlowski Cc: Rob Herring Signed-off-by: Tony Lindgren

ARM: dts: logicpd-torpedo: Add isp1763 support to baseboard

2022-02-18T08:30:02+00:00

The baseboard has an ISP1763 USB controller acting as a host. Since the pinmuxing for the corresponding IRQ is different between OMAP35 and DM37, the pinmux has been placed in the kit-level files, while the common code is placed into the baseboard file.

ARM: dts: logicpd-torpedo-37xx-devkit: Increase camera pixel clock

2019-10-22T16:33:34+00:00

The default settings used on the baseboard are good for the OMAP3530 and are compatible with the DM3730. However, the DM3730 has a faster L3 clock which means the camera pixel clock can also be pushed faster as well. This patch increase the Pixel clock to 90MHz which is the maximum the current ISP driver permits for an L3 clock of 200MHz. Signed-off-by: Adam Ford Signed-off-by: Tony Lindgren

ARM: dts: logicpd-torpedo: Disable Bluetooth Serial DMA

2019-10-22T16:23:11+00:00

The default serial driver for omap2plus is the 8250_omap driver. Unfortunately, this driver does not yet appear to have fully functional DMA on OMAP3630/DM3730 which causes some timeouts and frame errors. This patch removes the DMA entry from the device tree which allow the UART to operate without Bluetooth frame errors. If/when DMA is working on OMAP3630, this should be reverted.

ARM: dts: Improve omap l4per idling with wlcore edge sensitive interrupt

2018-07-03T06:57:20+00:00

The wl1835mod.pdf data sheet says this pretty clearly for WL_IRQ line: "WLAN SDIO out-of-band interrupt line. Set to rising edge (active high) by default." And it seems this interrupt can be optionally configured to use falling edge too since commit bd763482c82e ("wl18xx: wlan_irq: support platform dependent interrupt types"). On omap4, if the wlcore interrupt is configured as level instead of edge, L4PER will stop doing hardware based idling after ifconfig wlan0 down is done and the WL_EN line is pulled down. The symptoms show up with L4PER status registers no longer showing the IDLEST bits as 2 but as 0 for all the active GPIO banks and for L4PER_CLKCTRL. Also the l4per_pwrdm RET count stops increasing in the /sys/kernel/debug/pm_debug/count. While there is also probably a GPIO related issue that needs to be still fixed, this change gets us to the point where we can have L4PER idling. I'm guessing wlcore was at some point configured to use level interrupts because of edge handling issues in gpio-omap. However, with the recent fixes to gpio-omap the edge interrupts seem to be working just fine. Let's change it for all omap boards with wlcore interrupt set as level.

2017-12-11T17:43:53+00:00

The newly added OMAP35xx Torpedo does not have a WiFi option, so this patch moves the WL1283 binding and pin muxing to the logicpd-torpedo-37xx-devkit since it's only applicable on that SOM Signed-off-by: Adam Ford Signed-off-by: Tony Lindgren
