pinctrl: tegra: Add SFIO/GPIO programming on Tegra194

2020-03-27T10:46:06+00:00

Prior to Tegra186, the selection of SFIO vs. GPIO modes was done as part
of the GPIO controller's register programming. Starting with Tegra186, a
pin is configured as GPIO or SFIO with a bit in a configuration register
of the pin controller.

pinctrl: tegra: Renumber the GG.0 and GG.1 pins

2020-03-27T10:44:59+00:00

There is no need to define these at a specific offset since they are the
only pins defined for this SoC generation. Begin numbering them at 0.

pinctrl: tegra: Do not add default pin range on Tegra194

2020-03-27T10:44:30+00:00

On Tegra194, almost all of the pin control programming happens in early
boot firmware, so there is no use in having a pin range defined for all
the pins.

pinctrl: tegra: Pass struct tegra_pmx for pin range check

2020-03-27T10:42:32+00:00

Pass the struct tegra_pmx when checking for the pin range in device
tree. This makes the call site a bit easier to read and will help keep
that readability in a subsequent patch.

pinctrl: tegra: fix missing __iomem in suspend/resume

The functions should have __iomem on the register pointer
so add that to silence the following sparse warnings:

pinctrl: use devm_platform_ioremap_resource() to simplify code

2019-11-05T14:33:40+00:00

devm_platform_ioremap_resource() internally have platform_get_resource()
and devm_ioremap_resource() in it. So instead of calling them separately
use devm_platform_ioremap_resource() directly.

pinctrl: tegra: xusb: Add note about legacy status

2019-10-04T21:20:04+00:00

Add a comment about why the call to of_match_node() cannot be replaced
by of_device_get_match_data(). This will hopefully prevent people from
attempting to clean this up in the future.

pinctrl: tegra: Flush pinctrl writes during resume

2019-08-21T07:00:16+00:00

This patch adds pinctrl register read to flush all the prior pinctrl
writes and then adds barrier for pinctrl register read to complete
during resume to make sure all pinctrl changes are effective.
