2019-11-27net: mscc: ocelot: use skb queue instead of skbs listYangbo Lu1-8/+1
Convert to use skb queue instead of the list of skbs. The skb queue could provide protection with lock. Signed-off-by: Yangbo Lu <yangbo.lu@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-11-21net: mscc: ocelot: convert to use ocelot_port_add_txtstamp_skb()Yangbo Lu1-0/+2
Convert to use ocelot_port_add_txtstamp_skb() for adding skbs which require TX timestamp into list. Export it so that DSA Felix driver could reuse it too.

2019-11-21net: mscc: ocelot: convert to use ocelot_get_txtstamp()Yangbo Lu1-1/+8
The method getting TX timestamp by reading timestamp FIFO and matching skbs list is common for DSA Felix driver too. So move code out of ocelot_board.c, convert to use ocelot_get_txtstamp() function and export it.

Export ocelot_hwstamp_get/set functions so that DSA driver is able to reuse them. Signed-off-by: Yangbo Lu <yangbo.lu@nxp.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-11-15net: mscc: ocelot: publish ocelot_sys.h to include/soc/msccVladimir Oltean1-0/+144
The Felix DSA driver needs to write to SYS_RAM_INIT_RAM_INIT for its own chip initialization process. Also update the MAINTAINERS file such that the headers exported by the ocelot driver are under the same maintainers' umbrella as the driver itself.

2019-11-15net: mscc: ocelot: publish structure definitions to include/soc/mscc/ocelot.hVladimir Oltean1-0/+539
We will be registering another switch driver based on ocelot, which lives under drivers/net/dsa. Make sure the Felix DSA front-end has the necessary abstractions to implement a new Ocelot driver instantiation. This includes the function prototypes for implementing DSA callbacks.

2018-10-05net: mscc: ocelot: simplify register access for PLL5 configurationQuentin Schulz1-0/+74
Since HSIO address space can be accessed by different drivers, let's simplify the register address definitions so that it can be easily used by all drivers and put the register address definition in the include/soc/mscc/ocelot_hsio.h header file.

2018-10-05net: mscc: ocelot: move the HSIO header to include/socQuentin Schulz1-0/+785
Since HSIO address space can be used by different drivers (PLL, SerDes muxing, temperature sensor), let's move it somewhere it can be included by all drivers.
