* e200v1/c200v1: Implement limited samplerate switching. Rates 24kHz and below ↵Michael Sevakis2010-06-26
| | | | | | are being a bear as far as minor crackling at higher amplitude-- leave them out for the time being since no solution is currently evident. 48, 44, 32 (rec rates 24, 22, 16) seem perfectly fine. I'm betting c200 is ok to include because it uses the same setup as e200. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27139 a1c6a512-1295-4272-9138-f99709370657

| | | | | | say at this point about any change in battery life but it frees up a percent or two of CPU cycles as measured in the buffering screen. No change in recording transfers yet. Testing seemed to check out so put it out for general use and see what happens. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@20052 a1c6a512-1295-4272-9138-f99709370657

* Change c200 and e200 to use the same IIS FIFO format as seems to be working ↵Michael Sevakis2007-10-09
| | | | | | for others. Samples there have been packed for a long time though so no change to that. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15051 a1c6a512-1295-4272-9138-f99709370657

* Use halfword IIS FIFO mode for H10. Won't save interrupts but seems it ↵Michael Sevakis2007-10-07

* Unify PCM interface just above the hardware driver level for all targets ↵Michael Sevakis2007-10-06

* PP502x: Make RAM physical addresses uncached. Cache the flash ROM on targets ↵Michael Sevakis2007-10-04
| | | | | | with one. Kill all the now unneeded cache flushing and i2s tweaking on e200 so clicking is no worry. Write the driver framebuffer at uncached addresses. Recording monitoring may be a little noisy in the left channel for the moment when not boosted and will be addressed. All seems to work as advertised including flash ROM dump. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@14976 a1c6a512-1295-4272-9138-f99709370657
