* spi: imx: Define register bits in the driverMarek Vasut2021-01-231-30/+0
| | | | | | | | | | The CSPI/ECSPI register bits do not differ between newer SoCs, instead of having multiple copies of the same thing for each iMX SoC, define the bits in the driver.

* arm: Don't include common.h in header filesSimon Glass2020-05-181-2/+0
| | | | | | | | | | | It is bad practice to include common.h in other header files since it can bring in any number of superfluous definitions. It implies that some C files don't include it and thus may be missing CONFIG options that are set up by that file. The C files should include these themselves. Update some header files in arch/arm to drop this. Signed-off-by: Simon Glass <sjg@chromium.org>
* watchdog: mx25: use the imx_watchdog driver for mx25Martin Kaiser2018-09-041-0/+1
| | | | | | | | | | | | | | | | | The existing imx_watchdog driver is compatible with mx25 chipsets. Add a WDOG1_BASE_ADDR define for the base address and enable the driver in watchdog's Makefile. To use the driver, a board must define CONFIG_IMX_WATCHDOG and CONFIG_HW_WATCHDOG. This fixes an issue when booting an mx25 chip via usb/serial. In this case, the boot rom will always enable the watchdog. If u-boot is running in interactive mode and the watchdog is not serviced, the system is rebooted when the watchdog expires.

* mx25: fix the offset between the USB ports' registersMartin Kaiser2018-07-231-1/+6
| | | | | | | | | | | | | | | | | | The USBOH module on imx25 chips contains two USB controllers which are called USB OTG Controller and USB Host Controller. Each one has its EHCI root hub. The OTG Controller's EHCI registers start at offset 0, the Host Controller's registers start at offset 0x400. We set CONFIG_MXC_USB_PORT=0 to select the OTG Controller and 1 for the Host Controller. Therefore, IMX_USB_PORT_OFFSET must be 0x400. Using this setting, the Host Controller starts working on my imx25 board. Please note that the imx25 reference manual claims that the Host Controller's registers start at 0x200. This is not correct. The Linux Kernel uses the correct offset 0x400 in imx25.dtsi.

* SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini2018-05-075-10/+5
| | | | | | | | | | | | | | | | | | | | When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
* imx: mx25: Remove SION bit in all pin-mux that are safeMichael Trimarchi2018-02-041-281/+290
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SION bit should be used in the situation that we need to read back the value of a pin and should not be set by default macro. We get some malfunction as raised by following thread https://www.spinics.net/lists/linux-usb/msg162574.html As reported by this application note: https://www.nxp.com/docs/en/application-note/AN5078.pdf The software input on (SION) bit is an option to force an input path to be active regardless of the value driven by the corresponding module. It is used when the nature direction of a pin depending on selected alternative function is an output, but it is needed to read the real logic value on a pin. The SION bit can be used in: • Loopback: the module of a selected alternative function drives the pad and also receives the pad value as an input • GPIO capture: the module of a selected alternative function drives the pin and the value is captured by the GPIO SION bit is not necessary when the pin is configured as a peripheral apart specific silicon bug. If an application needs to have this set, this should be done in board file or in dts file Signed-off-by: Michael Trimarchi <michael@amarulasolutions.com> Reviewed-by: Benoît Thébaudeau <benoit.thebaudeau.dev@gmail.com> Signed-off-by: Michael Trimarchi <michael@amarulasolutions.com> Reviewed-by: Fabio Estevam <fabio.estevam@nxp.com>
