i3c: master: Use dev_to_i3cmaster()

2019-08-27T07:43:59Z

Since we have dev_to_i3cmaster() available, use it. Signed-off-by: Axel Lin Signed-off-by: Boris Brezillon

i3c: master: fix a memory leak bug

2019-08-12T08:11:29Z

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

2019-08-11T08:48:28Z

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

i3c: master: cdns: Use for_each_set_bit()

2019-08-11T08:45:52Z

This simplifies and standardizes slot manipulation code by using for_each_set_bit() library function. Signed-off-by: Andy Shevchenko Signed-off-by: Boris Brezillon

i3c: master: Add of_node_put() before return

2019-08-11T08:45:51Z

Each iteration of for_each_available_childe_of_node puts the previous node, but in the case of a return from the middle of the loop, there is no put, thus causing a memory leak. Add an of_node_put before the return. Issue found with Coccinelle. Signed-off-by: Nishka Dasgupta Signed-off-by: Boris Brezillon

i3c: move i3c_device_match_id to device.c and export it

2019-07-27T09:22:19Z

Some I3C device drivers need to know which entry matches the i3c_device object passed to the probe function Let's move i3c_device_match_id() to device.c and export it so it can be used by drivers. Signed-off-by: Vitor Soares Signed-off-by: Boris Brezillon

i3c: master: Use struct_size() helper

2019-07-04T10:05:14Z

Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes, in particular in the context in which this code is being used. So, replace the following form: sizeof(*defslvs) + ((ndevs - 1) * sizeof(struct i3c_ccc_dev_desc)) with: struct_size(defslvs, slaves, ndevs - 1) This code was detected with the help of Coccinelle.

i3c: dw: add limited bus mode support

i3c: add mixed limited bus mode

2019-06-20T07:23:22Z

The i3c bus spec defines a bus configuration where i2c devices don't have a 50ns filter but support SCL running at SDR max rate (12.5MHz). This patch introduces the limited bus mode so that users can use a higher speed in presence of i2c devices index 1. Signed-off-by: Vitor Soares Cc: Boris Brezillon Cc: Signed-off-by: Boris Brezillon
