treewide: convert devfdt_get_addr_ptr() to dev_read_addr_ptr()

2020-08-22T14:53:37Z

When you enable CONFIG_OF_LIVE, you will end up with a lot of conversions. To help this tedious work, this commit converts devfdt_get_addr_ptr() to dev_read_addr_ptr() by coccinelle. I also removed redundant casts because dev_read_addr_ptr() returns an opaque pointer. To generate this commit, I ran the following semantic patch excluding include/dm/. @@ type T; expression dev; @@ -(T *)devfdt_get_addr_ptr(dev) +dev_read_addr_ptr(dev) @@ expression dev; @@ -devfdt_get_addr_ptr(dev) +dev_read_addr_ptr(dev) Signed-off-by: Masahiro Yamada Reviewed-by: Simon Glass

dm: core: Fix devfdt_get_addr_ptr return value

2020-08-22T13:59:14Z

According to the description of devfdt_get_addr_ptr, this function should return NULL on failure, but currently it returns (void *)FDT_ADDR_T_NONE. Fix this by making devfdt_get_addr_ptr return NULL on failure, as described in the function comments. Also, update the drivers currently checking (void *)FDT_ADDR_T_NONE to check for NULL.

watchdog: Add support for K3 RTI watchdog

2020-08-11T04:48:27Z

This is based on the Linux kernel driver for the RTI watchdog. To actually reset the system on an AM65x, it requires firmware running on the R5 that accepts the NMI and issues the actual system reset via TISCI. Kind of an iTCO, except that this watchdog hardware has support for no-way-out, and only for that. On the J721E, reset works without extra firmware help when routing the RTI interrupt via the ESM.

Watchdog: introduce ARM SBSA watchdog driver

2020-07-27T08:54:15Z

According to Server Base System Architecture (SBSA) specification, the SBSA Generic Watchdog has two stage timeouts: the first signal (WS0) is for alerting the system by interrupt, the second one (WS1) is a real hardware reset. More details about the hardware specification of this device: ARM DEN0029B - Server Base System Architecture (SBSA) This driver can operate ARM SBSA Generic Watchdog as a single stage In the single stage mode, when the timeout is reached, your system will be reset by WS1. The first signal (WS0) is ignored. Signed-off-by: Zhao Qiang Signed-off-by: Biwen Li Reviewed-by: Stefan Roese Reviewed-by: Priyanka Jain

treewide: convert devfdt_get_addr() to dev_read_addr()

treewide: convert (void *)devfdt_get_addr() to dev_read_addr_ptr()

2020-07-25T20:46:57Z

Use the _ptr suffixed variant instead of casting. Also, convert it to dev_read_addr_ptr(), which is safe to CONFIG_OF_LIVE. One curious part is an error check like follows in drivers/watchdog/omap_wdt.c: priv->regs = (struct wd_timer *)devfdt_get_addr(dev); if (!priv->regs) return -EINVAL; devfdt_get_addr() returns FDT_ADDR_T_NONE (i.e. -1) on error. So, this code does not catch any error in DT parsing. dev_read_addr_ptr() returns NULL on error, so this error check will work. I generated this commit by the following command: $ find . -name .git -prune -o -name '*.[ch]' -type f -print | \ xargs sed -i -e 's/([^*)]*\*)devfdt_get_addr(/dev_read_addr_ptr(/' I manually fixed drivers/usb/host/ehci-mx6.c Signed-off-by: Masahiro Yamada
