* Bring a few simplifications to a10_gpio:Luiz Otavio O Souza2015-07-131-155/+103
| | | | | | | | | | | | | | o Return the real hardware state in gpio_pin_getflags() instead of keep the last state in an internal table. Now the driver returns the real state of pins (input/output and pull-up/pull-down) at all times. o Use a spin mutex. This is required by interrupts and the 1-wire code. o Use better variable names and place parentheses around them in MACROS. o Do not lock the driver when returning static data. Tested with gpioled(4) and DS1820 (1-wire) sensors on banana pi. Notes: svn path=/head/; revision=285484

| | | | | | | | | | | | | | | | change to GMAC easier on A20 SoCs. On A10 only the EMAC controller is available (fast ethernet), but on A20 there is also GMAC a high (or better) performant controller (gigabit ethernet). On A20 the both controllers uses the same pins to talk to the ethernet PHY (MII or RGMII) and they can be selected by the GPIO pin mux. There is work in progress to bring in GMAC support.

* Add AHCI attachment code for Allwinner A10/A20 SoCs.Luiz Otavio O Souza2015-07-034-0/+412
| | | | | | | | | | | | | | | | | | | | | | | | The Allwinner SoC has an AHCI device on its internal main bus rather than the PCI bus. This SoC is somewhat underdocumented, and its SATA controller is no exception. The methods to support this chip were harvested from the Linux Allwinner SDK, and then constants invented to describe what's going on based on low-level constants contained in the SATA standard and guess work. This SoC requires a specific AHCI channel setup in order to start the operations on the channel properly. Clock setup and AHCI channel setup idea came from NetBSD. Tested on Cubieboard 2 and Banana pi (and attachment on Cubieboard by Pratik Singhal).

* Add DMA support for Allwinner MMC controller.Luiz Otavio O Souza2015-07-012-22/+237
| | | | | | | | | | | | | | | DMA handles all data transfers up to 128K or 16 segments and fallback to pio mode when DMA requirements are not met. The read performance has improved greatly while the write performance also showed some improvement but seems limited by the card type and quality.

* Add the MMC/SD driver for Allwinner SoCs.Luiz Otavio O Souza2015-05-215-1/+1007
| | | | | | | | | | | | | | | | | | | | | | | | | This is based on the patch sent by Alexander Fedorov with the following fixes/improvements: - Better error handling; - Clock is derived from PLL6 (obtained from netbsd); - No more unnecessary busy loops on interrupt handler; - style(9) fixes and code cleanup. I also want to thanks Martin Galvan who has sent an alternative implementation with some interesting fixes. Tested on CubieBoard2, Banana-Pi (thanks to netgate!) and Cubieboard1 (Pratik Singhal). This is intended to pave the way for the upcoming GSoC work (and make easier the build of images for the supported boards).

* Add the necessary support to use both TX queues available on if_emac.Luiz Otavio O Souza2015-04-172-12/+29
| | | | | | | | | | | | | | | Each TX queue can hold one packet (yes, if_emac can send only two(!) packets at a time). Even with this change the very limited FIFO buffer (3 KiB for TX and 13 KiB for RX) fill up too quick to sustain higher throughput. For the TCP case it turns out that TX isn't the limiting factor, but the RX side is (the FIFO fill up and starts to discard packets, so the sender has to slow down).

* Fix the 'wrong packet header' errors for if_emac.Luiz Otavio O Souza2015-04-171-3/+1
| | | | | | | | | | | | | | Do not strip the ethernet CRC until we read all data from FIFO, otherwise the CRC bytes would be left in FIFO causing the failure of next packet (wrong packet header). When this error happens the receiver has to be disabled and the RX FIFO flushed, discarding valid packets. With this fix if_emac behaves a lot better. Notes: svn path=/head/; revision=281639

Simplebus used to only instantiate its children whose status="okay" but that was improper behavior, fixed in r261352. Now that it doesn't check anymore and probes all its children; the children all have to do the check because really only the children know how to properly interpret their status property strings. Right now all existing drivers only understand "okay" versus something- that's-not-okay, so they all use the new ofw_bus_status_okay() helper. Notes: svn path=/head/; revision=261410
