2019-01-18Staging: fbtft: Switch to the gpio descriptor interfaceNishad Kamdar27-587/+143
This switches the fbtft driver to use GPIO descriptors rather than numerical gpios: Utilize the GPIO library's intrinsic handling of OF GPIOs and polarity. If the line is flagged active low, gpiolib will deal with this. Remove gpios from platform device structure. Neither assign statically numbers to gpios in platform device nor allow gpios to be parsed as module parameters.

2019-01-18staging: android: ion: Remove struct ion_platform_heapAndrew F. Davis3-41/+11
Now that ION heap registration has been re-worked to not depend on board files or have a central heap register helper there is no need to have this data structure. Most of the fields are unused. Some heap creation helpers are still available that use this to define the a heap but only use 2 or 3 elements from this struct, just convert these to get supplied these values from the heap registrar directly.

2019-01-15staging: rtl8712u: Fix suspend and resume callbacksKai-Heng Feng1-8/+0
When system resume and the rtl8712u dongle didn't lose its power, it doesn't work quite right: [ 146.844241] r8712u 2-3:1.0 wlp0s4f1u3: Unable to resume ... [ 154.029573] r8712u 2-3:1.0 wlp0s4f1u3: In r8711_wx_set_scan: bDriverStopped=1 The !netif_running() check in PM callbacks aren't correct because rtl8712u doesn't support runtime suspend, so the when the PM ops get called, it's system suspend or system resume, hence we want to "stop everthing" or "resume everything". The NULL check on pnetdev is also redundant, the only place pnetdev can become NULL is the disconnect callback, which is mutually exclusive to PM callbacks. This can make rtl8712u starts working after system resume. Signed-off-by: Kai-Heng Feng <kai.heng.feng@canonical.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2019-01-15staging: rtl8712u: Remove dummy reset-resume callbackKai-Heng Feng1-8/+0
An USB wireless dongle uses rtl8712u stops working after system suspend/resume. When a USB device lost its power during suspend, the USB core knows the power was lost and a reset-resume or a re-probe is required. But rtl8712u provides a dummy reset-resume callback, which gets called and renders the device dead after resume. So remove the reset-resume call back, if power was lost during suspend, let the USB core unbind and probe the device to solve the issue.
