nfc: pn532: Add uart phy docs and rename it

2019-10-30T04:05:26Z

This adds documentation about the uart phy to the pn532 binding doc. As the filename "pn533-i2c.txt" is not appropriate any more, rename it to the more general "pn532.txt". This also documents the deprecation of the compatible strings ending with "...-i2c". Cc: Johan Hovold Cc: Simon Horman Reviewed-by: Rob Herring Signed-off-by: Lars Poeschel Signed-off-by: David S.

treewide: convert ISO_8859-1 text comments to utf-8

2018-08-24T01:48:43Z

Almost all files in the kernel are either plain text or UTF-8 encoded. A couple however are ISO_8859-1, usually just a few characters in a C comments, for historic reasons. This converts them all to UTF-8 for consistency.

dt-bindings: remove 'interrupt-parent' from bindings

2018-07-25T20:09:39Z

'interrupt-parent' is often documented as part of define bindings, but it is really outside the scope of a device binding. It's never required in a given node as it is often inherited from a parent node. Or it can be implicit if a parent node is an 'interrupt-controller' node. So remove it from all the binding files.

dt-bindings: Remove "status" from examples

2017-09-05T15:03:06Z

Pretty much any node can have a status property, so it doesn't need to be in examples. Converted with the following command and removed examples with SoC and board specific splits: git grep -l -E 'status.*=.*' Documentation/devicetree/ | xargs sed -i -E '/\sstatus.*=.*"(disabled|ok|okay)/d' Acked-by: Mark Rutland Signed-off-by: Rob Herring

Revert "NFC: trf7970a: Handle extra byte in response to Type 5 RMB commands"

2017-06-22T22:20:00Z

This reverts commit ab714817d7e891608d31f6996b1e4c43cf2bf342. The original commit was designed to handle a bug in the trf7970a NFC controller where an extra byte was returned in Read Multiple Blocks (RMB) command responses. However, it has become less clear whether it is a bug in the trf7970a or in the tag. In addition, it was assumed that the extra byte was always returned but it turns out that is not always the case. The result is that a byte of good data is trimmed off when the extra byte is not present ultimately causing the neard deamon to fail the read. Since the trf7970a driver does not have the context to know when to trim the byte or not, remove the code from the trf7970a driver all together (and move it up to the neard daemon). This has the added benefit of simplifying the kernel driver and putting the extra complexity into userspace.

NFC: trf7970a: Enable pins are active high not active low

2017-06-18T21:57:58Z

The example DTS code for the trf7970a sets the GPIOs for the EN and EN2 pins to active low when they are really active high so correct the error. Acked-by: Rob Herring Signed-off-by: Mark Greer Signed-off-by: Samuel Ortiz

NFC: trf7970a: Remove support for 'vin-voltage-override' DT property

2017-06-18T21:57:58Z

The 'vin-voltage-override' DT property is used by the trf7970a driver to override the voltage presented to the driver by the regulator subsystem. This is unnecessary as properly specifying the regulator chain via DT properties will accomplish the same thing. Therefore, remove support for 'vin-voltage-override'.

NFC: trf7970a: Add device tree option of 1.8 Volt IO voltage

2017-04-05T09:04:03Z

The TRF7970A has configuration options for supporting hardware designs with 1.8 Volt or 3.3 Volt IO. This commit adds a device tree option, using a fixed regulator binding, for setting the io voltage to match the hardware configuration. If no option is supplied it defaults to 3.3 volt configuration.

NFC: trf7970a: add device tree option for 27MHz clock

2017-04-05T09:03:47Z

The TRF7970A has configuration options to support hardware designs which use a 27.12MHz clock. This commit adds a device tree option 'clock-frequency' to support configuring the this chip for default 13.56MHz clock or the optional 27.12MHz clock.

NFC: Make EN2 pin optional in the TRF7970A driver

2017-04-01T22:32:34Z

Make the EN2 pin optional. This is useful for boards, which have this pin fix wired, for example to ground. Acked-by: Rob Herring Signed-off-by: Guan Ben Signed-off-by: Mark Jonas Signed-off-by: Heiko Schocher Signed-off-by: Samuel Ortiz
