i3c: master add i3c_master_attach_boardinfo to preserve boardinfo

2020-10-29T09:11:37+00:00

[ Upstream commit 9da36a7ec42135428e1d41621e3703429bda3b2e ] Boardinfo was lost if I3C object for devices with boardinfo available are not created or not added to the I3C device list because of some failure e.g. SETDASA failed, retrieve info failed etc This patch adds i3c_master_attach_boardinfo which scan boardinfo list in the master object and 'attach' it to the I3C device object.

i3c master: GETMRL's 3rd byte is optional even with BCR_IBI_PAYLOAD

2020-04-16T12:27:46+00:00

According to the I3C spec v1.1 document, GETMRL's payload is 2 bytes, with an optional 3rd byte if the IBI private payload is larger than 1 byte. The whole GETMRL may also be optional so max_ibi_len already defaults to 1 if BCR_IBI_PAYLOAD prior to the i3c_master_getmrl_locked() call.
