phy: marvell: phy-mvebu-cp110-comphy: rename instances of DLT

2019-08-27T06:07:09+00:00

The documentation for Marvell's cp110 phy refers to these registers/register regions as DTL control, DTL frequency loop enable, etc. This patch aligns the relevant code for these accordingly. Signed-off-by: Matt Pelland Signed-off-by: Kishon Vijay Abraham I

phy: marvell: phy-mvebu-cp110-comphy: implement RXAUI support

2019-08-27T06:07:09+00:00

Marvell's cp110 phy supports RXAUI on lanes 2, 3, 4, and 5 when connected to port zero. When used in this mode, lanes operate in pairs of two (2 and 3, 4 and 5). Signed-off-by: Matt Pelland Signed-off-by: Kishon Vijay Abraham I

phy: mvebu-cp110-comphy: Update comment about powering off all lanes at boot

2019-08-27T06:07:09+00:00

Now that all COMPHY modes are supported by the driver, update the comment stating that mvebu_comphy_power_off() should be called for each lane. This is still wrong because for compatibility reasons, it might break users running an old firmware (the driver only uses SMC calls for SATA, USB and PCIe configuration, there is no code in Linux to fallback on in these cases.

phy: mvebu-cp110-comphy: Add PCIe support

2019-08-27T06:07:09+00:00

Add PCIe support by filling the COMPHY modes table. Also add a new macro to generate the right value for the firmware depending on the width (PCI x1, x2, x4, etc). The width will be passed by the core as the "submode" argument of the ->set_mode() callback. If this argument is zero, default to x1 mode.

phy: mvebu-cp110-comphy: Cosmetic change in a helper

2019-08-27T06:07:09+00:00

Before adding more logic, simplify a bit the writing of the mvebu_comphy_get_mode() helper by using a pointer instead of referencing a configuration with the entire table name. Signed-off-by: Miquel Raynal Signed-off-by: Kishon Vijay Abraham I

phy: mvebu-cp110-comphy: Add SATA support

2019-08-27T06:07:09+00:00

Add the corresponding entries in the COMPHY modes table. SATA support does not need any additional care. Signed-off-by: Grzegorz Jaszczyk [miquel.raynal@bootlin.com: adapt the content to the mainline driver] Signed-off-by: Miquel Raynal Signed-off-by: Kishon Vijay Abraham I

phy: mvebu-cp110-comphy: Add USB3 host/device support

2019-08-27T06:07:09+00:00

Add USB3 host/device support by adding the right entries in the COMPHY modes table. A new macro is created to instantiate a "generic" mode ie. not an Ethernet one. This macro will be re-used when adding SATA support.

phy: mvebu-cp110-comphy: Allow non-Ethernet modes to be configured

2019-08-27T06:07:09+00:00

The COMPHY can configure the SERDES lanes in several non-Ethernet modes: SATA, USB3, PCIe. Drop the condition limiting the driver to Ethernet modes only before adding support for more. Signed-off-by: Miquel Raynal Signed-off-by: Kishon Vijay Abraham I

phy: mvebu-cp110-comphy: Rename the macro handling only Ethernet modes

2019-08-27T06:07:09+00:00

Before adding support for other PHY modes (not Ethernet ones), let's rename the MVEBU_COMPHY_CONF macro to a more specific (and shorter) appellation. Signed-off-by: Miquel Raynal Signed-off-by: Kishon Vijay Abraham I

phy: mvebu-cp110-comphy: Add RXAUI support

2019-08-27T06:07:09+00:00

Add support for RXAUI mode by adding an entry in the COMPHY modes list. There is no user for this mode yet so we can enforce an up-to-date firmware and return an error otherwise without breaking anywone.
