i3c: master: dw: reattach device on first available location of address table

2020-01-13T09:00:05+00:00

For today the reattach function only update the device address on the controller. Update the location to the first available too, will optimize the enumeration process avoiding additional checks to keep the available positions on address table consecutive.

i3c: master: make i3c_bus_set_mode static

2019-12-09T15:07:39+00:00

i3c_bus_set_mode function is only used in master.c. Make it static to avoid warning when compiling with W=1. Signed-off-by: Benjamin Gaignard Signed-off-by: Boris Brezillon

i3c: master: cdns: add data hold delay support

2019-12-09T15:07:21+00:00

This patch adds support for THD_DEL (Data Hold Delay) to Cadence I3C master constoller driver. As per MIPI I3C Specification 1.0, Table 75 (page 142) defines non-zero minimal tHD_PP timing on master output (Fig 65). This setting allows to meet this timing on master's soc outputs, regardless of PCB balancing. Signed-off-by: Przemyslaw Gaj Signed-off-by: Boris Brezillon

i3c: master: fix a memory leak bug

2019-08-12T08:11:29+00:00

In i3c_master_getmwl_locked(), the buffer used for the dest payload data is allocated using kzalloc() in i3c_ccc_cmd_dest_init(). Later on, the length of the dest payload data is checked against 'sizeof(*mwl)'. If they are not equal, -EIO is returned to indicate the error. However, the allocated buffer is not deallocated on this path, leading to a memory leak. To fix the above issue, free the buffer before returning the error.

i3c: add addr and lvr to i2c_dev_desc structure

2019-08-11T08:48:28+00:00

I need to store address and lvr value for I2C devices without static definition in DT. This allows secondary master to transmit DEFSLVS command properly. Main changes between v4 and v5: - Change in defslvs to use addr and lvr from i2c_dev_desc structure - Change in CDNS and DW drivers to use addr and lvr from i2c_dev_desc structure Signed-off-by: Przemyslaw Gaj Signed-off-by: Boris Brezillon
