Subject: [PATCH v3 0/3] Add support for WDIOF_CARDRESET on TI AM65x
Date: Thu, 13 Jul 2023 17:51:24 +0800 [thread overview]
Message-ID: <20230713095127.1230109-1-huaqian.li@siemens.com> (raw)
From: Li Hua Qian <huaqian.li@siemens.com>
The watchdog hardware of TI AM65X platform does not support
WDIOF_CARDRESET feature, add a reserved memory to save the watchdog
reset cause, to know if the board reboot is due to a watchdog reset.
Changes in v3:
- Add memory-region back for the reserved memory, and remove reserved
memory from the watchdog IO address space.
- Add changelog.
- Link to v2:
https://lore.kernel.org/linux-watchdog/20230711091713.1113010-1-huaqian.li@siemens.com
Changes in v2:
- Remove memory-region and memory-size properties, and bind the reserved
memory to watchdog IO address space.
- Remove the unnecessary rti_wdt_ioctl.
- Fix the mail list
- Link to v1:
https://lore.kernel.org/all/3137d87e56ef75ba0b8a923d407b2fecace6ccbd.camel@siemens.com/
v1 had a wrong mail list at the beginning, and the mail thread was
messed up.
