Subject: [PATCH] overlays: Fix some unusable fragments
|
||||||
|
|
||||||
|
A forthcoming overlaycheck update looks for dormant fragments with no
|
||||||
|
parameters to enable them. The test discovered some real errors, which
|
||||||
|
this patch fixes, and one case where some fragments aren't yet being
|
||||||
|
used, which this comments out until they are.

Subject: [PATCH] dts: rp1: Don't use DMA with UARTs
|
||||||
|
|
||||||
|
DMA has been enabled on RP1's UART0, but with mixed success. Transmits
|
||||||
|
seem to work, but the DMA interface is not well suited to receiving
|
||||||
|
arbitrary amounts of data. In particular, the PL011 driver is slow to
|
||||||
|
pass on the received data, batching it into large blocks.
|
||||||
|
|
||||||
|
On balance, it's better to just disable the DMA support. As with the
|
||||||
|
other UARTs, the required runes are left in the DTS as comments.
