phy: fix build breakage: add PHY_MODE_SATA

2019-01-13T05:07:14+00:00

Commit 49e54187ae0b ("ata: libahci_platform: comply to PHY framework") uses
the PHY_MODE_SATA, but that enum had not yet been added. This caused a
build failure for me, with today's linux.git.

Also, there is a potentially conflicting (mis-named) PHY_MODE_SATA, hiding
in the Marvell Berlin SATA PHY driver.

Fix the build by:

    1) Renaming Marvell's defined value to a more scoped name,
       in order to avoid any potential conflicts: PHY_BERLIN_MODE_SATA.

    2) Adding the missing enum, which was going to be added anyway as part
       of [1].

phy: qcom-qmp: Utilize fully-specified DT registers

2018-12-12T04:32:11+00:00

Utilize the newly fixed up DT bindings to get the tx2 and rx2 register
regions for the second lane of dual-lane PHYs. Before this change,
the driver was simply using lane one's register region and adding
0x400, which reached well beyond the DT-specified register
allocation. This would have been a crash were it not for the page size
on ARM64. Fix the driver not to rely on the magic of virtual memory by
using the newly specified DT register regions for tx2 and rx2.

In order to support existing device trees, this change also contains a
fallback mode for when those new register regions don't exist, which
reverts to the original behavior of overreaching and prints a complaint.

phy: dphy: Add configuration helpers

2018-12-12T04:31:51+00:00

The MIPI D-PHY spec defines default values and boundaries for most of the
parameters it defines. Introduce helpers to help drivers get meaningful
values based on their current parameters, and validate the boundaries of
these parameters if needed.

phy: Add configuration interface

2018-12-12T04:31:50+00:00

The phy framework is only allowing to configure the power state of the PHY
using the init and power_on hooks, and their power_off and exit
counterparts.

While it works for most, simple, PHYs supported so far, some more advanced
PHYs need some configuration depending on runtime parameters. These PHYs
have been supported by a number of means already, often by using ad-hoc
drivers in their consumer drivers.

That doesn't work too well however, when a consumer device needs to deal
with multiple PHYs, or when multiple consumers need to deal with the same
PHY (a DSI driver and a CSI driver for example).

So we'll add a new interface, through two funtions, phy_validate and
phy_configure. The first one will allow to check that a current
configuration, for a given mode, is applicable. It will also allow the PHY
driver to tune the settings given as parameters as it sees fit.

phy_configure will actually apply that configuration in the phy itself.

phy: Use of_node_name_eq for node name comparisons

2018-12-12T04:31:44+00:00

Convert string compares of DT node names to use of_node_name_eq helper
instead. This removes direct access to the node name pointer.

For instances using of_node_cmp, this has the side effect of now using
case sensitive comparisons. This should not matter for any FDT based
system which all of these are.
