Hello,
I have one patch that enables the spi initialization of the WM510205 audio codec Without the patch, this message indicates that the codec chip fails with the current chipselect number in spi-pxa2xx:
[ 0.296256] pxa2xx-spi 80860F0E:00: cs1 >= max 1 [ 0.296270] spi_master spi32766: failed to add SPI device WM510205:00 from ACPI
So raise num_chipselect by one to enable the codec. The WM510202 is on chipselect = 1.
With the patch applied I got in dmesg now:
[ 6.056829] pxa2xx-spi 80860F0E:00: no DMA channels available, using PIO [ 6.067035] pxa2xx-spi 80860F0E:00: registered master spi32766 (dynamic) [ 6.067214] spi spi-WM510205:00: 8333333 Hz actual, PIO [ 6.067221] spi spi-WM510205:00: setup mode 0, 8 bits/w, 8000000 Hz max --> 0 [ 6.067287] pxa2xx-spi 80860F0E:00: registered child spi-WM510205:00
