drivers: use dev_read_addr_ptr when cast to pointer

2023-05-06T09:28:18Z

The fdt_addr_t and phys_addr_t size have been decoupled. A 32bit CPU can expect 64-bit data from the device tree parser, so use dev_read_addr_ptr instead of the dev_read_addr function in the various files in the drivers directory that cast to a pointer. As we are there also streamline the error response to -EINVAL on return. Signed-off-by: Johan Jonker Reviewed-by: Simon Glass

Merge branch 'for-2023.07' of https://source.denx.de/u-boot/custodians/u-boot-mpc8xx

2023-04-29T13:29:41Z

This pull request adds support for the last CPU board from CS GROUP France (previously CSSI). That CPU board called CMPCPRO has a mpc8321E CPU (Family PQII PRO hence its name) and can be plugged in place of the CMPC885 board. In order to support that new board, the following changes are included in this series: - Make the mpc8xx watchdog driver more generic for reusing it with mpc83xx - Fix various small problems on mpc83xx platform - Add a GPIO Driver for QE GPIOs - Add support for mpc832x into mpc83xx SPI driver - Refactor existing board code that will be shared with new board - Add the new board

watchdog: ftwdt010: return a previously deleted driver now ported to DM

2023-04-18T06:42:43Z

The ftwdt010 watchdog driver was deleted by commit 11232139e399 ("nds32: Remove the architecture") Return it to the codebase in a DM compatible form. Enable it in sandbox_defconfig to test compilability. Another platform using ftwdt010 will be submitted later. Signed-off-by: Sergei Antonov Reviewed-by: Stefan Roese

watchdog: Add a watchdog driver for Raspberry Pi boards

2023-04-18T06:42:43Z

This driver supports the bcm2835 watchdog found on Raspberry Pi boards. It is derived from the Linux driver and was tested on two Raspberry Pi board versions (B+ and 3B+). Signed-off-by: Etienne Dublé Reviewed-by: Stefan Roese

watchdog: mpc8xxx: Add support for mpc83xx

2023-04-06T12:50:03Z

Introduce a new compatible "fsl,pq2pro-wdt" On mpc83xx, the prescaling factor is 0x10000. Don't write the watchdog configuration register in start.S as it can be written only once. Signed-off-by: Christophe Leroy

watchdog: mpc8xxx: Make it generic

2023-04-06T12:47:47Z

mpc8xx, mpc83xx and mpc86xx have similar watchdog with almost same memory registers. Refactor the driver to get the register addresses from the device tree and use the compatible to know the prescale factor. Calculate the watchdog setup value from the provided timeout. Don't declare it anymore as an HW_WATCHDOG, u-boot will start servicing the watchdog early enough. On mpc8xx the watchdog configuration register is also used for configuring the bus monitor. So add it as an option to the watchdog when it is mpc8xx. When watchdog is not selected, leave the configuration of the initial SYPCR from Kconfig. Signed-off-by: Christophe Leroy

watchdog: mpc8xx: Rename it mpc8xxx
