2020-09-18Headphone / lineout pause/resume #FS13237William Wilgus1-1/+3
Allow Lineout to behave like headphone port in regards to plug/unplug pause/resume Change-Id: I9cb2c9c40e0bdf3bf7e1e272164acd343f6b3850
2020-09-17jz4760: Heavily rework USB driver to add working DMA supportSolomon Peachy2-139/+245
* DMA Bulk IN (ie our TX) results in sequential transfers 33-68% faster. * DMA Bulk OUT (ie RX) is mostly stripped out due to complete brokenness. * Interrupt and control endpoints remain PIO-driven. Other improvements: 1) Use consistent endpoint references (no magic numbers) 2) Greatly enhanced logging 3) DMA support can be compiled out completely 4) Setting lockswitch will disable all DMA operations at runtime 5) Much more robust error checking and recovery Change-Id: I57b82e655e55ced0dfe289e379b0b61d8fe443b4

2020-09-13Xduoo X3 Add tree scrolling FS#13240, Emulate Multibutton pressesWilliam Wilgus2-19/+50
Fixes deficiencies with the button system on the X3 The x3 has an interesting button layout. Multiple key presses are NOT supported unless [BUTTON_POWER] is one of the combined keys As you can imagine this causes problems as the power button takes precedence in the button system and initiates a shutdown if the key is held too long instead of BUTTON_POWER use BUTTON_PWRALT in combination with other keys IF using as a prerequsite button then BUTTON_POWER should be used Multiple buttons are emulated by button_read_device but there are a few caveats to be aware of: Button Order Matters! different keys have different priorities, higher priority keys 'overide' the lower priority keys VOLUP[7] VOLDN[6] PREV[5] NEXT[4] PLAY[3] OPTION[2] HOME[1] There will be no true release or repeat events, the user can let off the button pressed initially and it will still continue to appear to be pressed as long as the second key is held Tree scrolling is PLAY+NEXT or PLAY+PREV Change-Id: I88dfee1c70a6a99659e8227f5becacc50cc43910

PLL1 clock for those frequencies has been dropped from 508 to 169.5 MHz, so it's still a respectable reduction. (I'm not sure how/why it ever worked with the XTAL source, but it did, and was off by an audible amount) Change-Id: I614d87e7dfdfe9210702b9c646d3863c06d6780b
