2019-02-27usb: chipidea: imx: set power polarityPhilipp Puschmann1-2/+2
This patch adds support to set the power line polarity for i.MX SoCs. To let the USB controller control the power it may be necessary to configure the polarity of the power line. So far the polarity was configured by Bootloader or alternatively the power line was muxed as gpio and driven by a regulator. Also make use of of_property_read_bool.

2018-12-11usb: chipidea: imx: Warn if oc polarity isn't specifiedUwe Kleine-König1-0/+2
The polarity of the over current detection pin isn't configured on i.MX6/7 if it's unspecified in the device tree. So the actual configuration depends on bootloader behavior which is bad. So encourage users to fix their device tree by issuing a warning in this case. Signed-off-by: Uwe Kleine-König <[email protected]> Signed-off-by: Peter Chen <[email protected]>
2018-12-11usb: chipidea: imx: support configuring for active low oc signalUwe Kleine-König1-4/+12
The status quo on i.MX6 is that if "over-current-active-high" is specified in the device tree this is configured as expected. If the property is missing polarity isn't changed and so the polarity is kept as setup by the bootloader. Reset default is active high, so active low can only be used with help by the bootloader. On i.MX7 it is similar, but there disabling of over current detection has a similar inconsistency. This patch introduces a new property that allows to explicitly configure for active low over current detection and consistently sets this up. In the absence of an explicit configuration the bit is kept as is. On i.MX7 over current detection is used unless disabled in the device tree.

Traditionally, PORTSC should be set before initializing ULPI phys. But setting PORTSC before powering on the phy results in a kernel freeze on imx53 based GE PPD.

2017-11-07USB: chipidea: Remove redundant license textGreg Kroah-Hartman1-7/+0
Now that the SPDX tag is in all USB files, that identifies the license in a specific and legally-defined manner. So the extra GPL text wording can be removed as it is no longer needed at all. This is done on a quest to remove the 700+ different ways that files in the kernel describe the GPL license text. And there's unneeded stuff like the address (sometimes incorrect) for the FSF which is never needed. No copyright headers or other non-license-description text was removed.

It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the drivers/usb/ and include/linux/usb* files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text.

In order to use ULPI phy with usb host 2 and 3, we need to configure controller register to enable ULPI features. Each USB controller have different behaviour, so in order to avoid to have several "swicth(data->index)" and lock/unlock, we prefer to get the index switch and then test for features if they exist for this index.

2013-11-14Merge branch 'for-linus-dma-masks' of git://git.linaro.org/people/rmk/linux-armLinus Torvalds1-4/+3
Pull DMA mask updates from Russell King: "This series cleans up the handling of DMA masks in a lot of drivers, fixing some bugs as we go. Some of the more serious errors include: - drivers which only set their coherent DMA mask if the attempt to set the streaming mask fails. - drivers which test for a NULL dma mask pointer, and then set the dma mask pointer to a location in their module .data section - which will cause problems if the module is reloaded. To counter these, I have introduced two helper functions: - dma_set_mask_and_coherent() takes care of setting both the streaming and coherent masks at the same time, with the correct error handling as specified by the API. - dma_coerce_mask_and_coherent() which resolves the problem of drivers forcefully setting DMA masks. This is more a marker for future work to further clean these locations up - the code which creates the devices really should be initialising these, but to fix that in one go along with this change could potentially be very disruptive. The last thing this series does is prise away some of Linux's addition to "DMA addresses are physical addresses and RAM always starts at zero". We have ARM LPAE systems where all system memory is above 4GB physical, hence having DMA masks interpreted by (eg) the block layers as describing physical addresses in the range 0..DMAMASK fails on these platforms. Santosh Shilimkar addresses this in this series; the patches were copied to the appropriate people multiple times but were ignored.
