Subject: [PATCH v2 0/6] i3c: master: some improvment for i3c master
Date: Wed, 18 Oct 2023 16:59:23 -0400 [thread overview]
Message-ID: <20231018205929.3435110-1-Frank.Li@nxp.com> (raw)
These are dependent on bugs fixed serial: https://lore.kernel.org/imx/20231016153232.2851095-1-Frank.Li@nxp.com/T/#t
There are three major improvement
1. Add actual size in i3c_transfer because i3c allow target early termiate
transfer.
2. Add API for i3c_dev_gettstatus_format1 for i3c comand GET_STATUS.
3. svc master enable hotjoin default
Change from v1 to v2.
- Hotjoin control by sys entry, default enable hotjoin, which standard i3c
feature, user can disable by echo 0 > /sys/bus/i3c/i3c-0/hotjoin
- use actual_len, add document
- using &xfers[i]
- still keep check cmd->xfer because i2c and ccc transfer, xfer is NULL.
- fixed issue found by checkpatch --strict
Frank Li (6):
