phy: ti: gmii-sel: do not fail in case of gmii

2020-02-20T12:36:57+00:00

The "gmii" PHY interface mode is supported on TI AM335x/437x/5xx SoCs, so
don't fail if it's selected.

phy: ti: gmii-sel: fix set of copy-paste errors

2020-02-20T12:36:57+00:00

- under PHY_INTERFACE_MODE_MII the 'mode' func parameter is assigned
instead of 'gmii_sel_mode' and it's working only because the default value
'gmii_sel_mode' is set to 0.

- console outputs use 'rgmii_id' and 'mode' values to print PHY mode
instead of using 'submode' value which is representing PHY interface mode
now.

This patch fixes above two cases.

phy: ti: j721e-wiz: Fix build error without CONFIG_OF_ADDRESS

2020-01-17T23:05:30+00:00

If CONFIG_OF_ADDRESS is not set and COMPILE_TEST=y, the following
error is seen while building phy-j721e-wiz.c

drivers/phy/ti/phy-j721e-wiz.o: In function `wiz_remove':
phy-j721e-wiz.c:(.text+0x1a): undefined reference to
`of_platform_device_destroy'

Fix the config dependency for PHY_J721E_WIZ here.

phy: ti: j721e-wiz: Fix return value check in wiz_probe()

2020-01-17T05:24:03+00:00

In case of error, the function devm_ioremap() returns NULL pointer not
ERR_PTR(). The IS_ERR() test in the return value check should be
replaced with NULL test.

phy: ti: j721e-wiz: Manage typec-gpio-dir

2020-01-14T05:20:19+00:00

Based on this GPIO state we need to configure LN10
bit to swap lane0 and lane1 if required (flipped connector).

Type-C companions typically need some time after the cable is
plugged before and before they reflect the correct status of
Type-C plug orientation on the DIR line.

Type-C Spec specifies CC attachment debounce time (tCCDebounce)
of 100 ms (min) to 200 ms (max).

Use the DT property to figure out if we need to add delay
or not before sampling the Type-C DIR line.

phy: ti: j721e-wiz: Add support for WIZ module present in TI J721E SoC

2020-01-14T05:20:19+00:00

Add support for WIZ module present in TI's J721E SoC. WIZ is a SERDES
wrapper used to configure some of the input signals to the SERDES. It is
used with both Sierra(16G) and Torrent(10G) SERDES. This driver configures
three clock selects (pll0, pll1, dig), two divider clocks and supports
resets for each of the lanes.

phy: ti-pipe3: make clk operations symmetric in probe and remove

2019-12-20T11:30:45+00:00

The driver calls clk_prepare_enable in probe but the corresponding
clk_disable_unprepare() is in ti_pipe3_disable_clocks().
Move clk_disable_unprepare() to remove to make them symmetric.

Pull char/misc driver updates from Greg KH:
 "Here is the big set of char/misc and other driver patches for 5.5-rc1

  Loads of different things in here, this feels like the catch-all of
  driver subsystems these days. Full details are in the shortlog, but
  nothing major overall, just lots of driver updates and additions.

  All of these have been in linux-next for a while with no reported
  issues"
